Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 641 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 642 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 643 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 644 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 645 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 646 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 647 Multifunction Electronic Control Modules: Connector Views Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 648 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 649 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 650 Multifunction Electronic Control Modules: Electrical Diagrams Diagram 59-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 651 Diagram 59-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 652 Diagram 59-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 653 Diagram 59-4 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 654 Diagram 59-5 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Page 655 Multifunction Electronic Control Modules: Service Precautions CAUTION: ^ Prior to removal of module, it is necessary to upload module configuration information to scan tool.

The A/C blower motor speed control is controlled by switching the control signal voltage of 5 volts OFF and ON 2,000 times per second. By varying the ratio of time on (+5 volts) to time off (0 volts), the EATC module tells the A/C blower motor speed control how fast the blower motor should run. The A/C blower motor speed control has the following features: ^ Has circuitry to protect the blower motor from burning out in the event of a locked rotor condition. ^ Can compensate for changes in battery positive voltage (B+) which prevents the blower speed from slowing down when the engine is idling and will provide up to a maximum of 30 amperes for blower motor operation with battery voltages between 10 and 16 volts. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Control Module HVAC > Component Information > Diagrams > Page 770 Control Module HVAC: Service and Repair REMOVAL 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 789 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 790 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 791 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 792 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 793 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 794 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Fuel Gauge Module > Component Information > Testing and Inspection Fuel Gauge Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that is a part of, please refer to Instrument Panel, Gauges and Warning Indicators; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Instrument Panel Control Module > Component Information > Technical Service Bulletins > Customer Interest for Instrument Panel Control Module: > 02-23-4 > Nov > 02 > Engine Controls - DTC P1635 Set After PCM/IC Replacement Technical Service Bulletin # 02-23-4 Date: 021125 Engine Controls - DTC P1635 Set After PCM/IC Replacement Article No. 02-23-4 11/25/02 ^ DIAGNOSTIC TROUBLE CODE (DTC) - P1635 AND/OR P1639 PRESENT AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT GASOLINE ENGINE VEHICLES ONLY ^ LAMP - 4X4 LAMP ILLUMINATED AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT - GASOLINE ENGINE VEHICLES ONLY ^ SPEEDOMETER - INACCURATE AND/OR INOPERATIVE AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT - GASOLINE ENGINE VEHICLES ONLY FORD: 1999-2002 MUSTANG 2000-2002 FOCUS 1999-2002 EXPEDITION, F-150 2000-2002 E SERIES 2001-2002 EXPLORER SPORT TRAC, EXPLORER SPORT, RANGER 2002 EXPLORER LINCOLN: 1999-2002 TOWN CAR, NAVIGATOR 2002 BLACKWOOD MERCURY: 2002 MOUNTAINEER Article 02-5-8 is being republished in its entirety to update the Service Procedure and to clarify build dates for Explorer.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 890 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 891 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 892 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules -

ISSUE Some vehicles may exhibit an inoperative or inaccurate speedometer, 4x4 lamp illuminated, and/or Diagnostic Trouble Code (DTCs) P1635 or P1639 present after a Powertrain Control Module (PCM) or Instrument Cluster replacement. This may be caused by the Vehicle Identification (VID) block that must be programmed when replacing the PCM. ACTION As part of the calibration, there is an area referred to as the Vehicle Identification (VID) block. The VID block must be programmed when replacing the PCM. Failure to perform the proper Programmable Module Installation procedure may generate fault code: P1639 VID Block not programmed or is corrupt--P1635 Tire/Axle Out Of Acceptable Range. Refer to the following procedures to ensure the PCM is properly configured.

In the event either code is set, use one of the following NGS Procedures "B" or "C" or WDS Procedure "D" to ensure the PCM is properly configured. NOTE THE FOLLOWING NGS PROCEDURES MUST BE PERFORMED USING THE NGS FLASH CABLE. Procedure A - NGS PREFERRED Method To Prevent P1635/P1639 1. With the original PCM installed and using the NGS service card, select "Programmable Module Installation". 2. Select PCM from the module list. 3. Select "Retrieve Module Config-Old ECU". 4. After the Module data has been stored, install the new PCM, press CANCEL to return to the menu and select "Restore Module Config-New ECU". This procedure will retrieve the VID data from the original PCM and store it into the new PCM. If the original PCM will not communicate, install the new PCM and start the procedure over at Step 1. If the new PCM VID is blank, the NGS will direct you to contact the As-Built Data center during Step a above. Obtain As-Built Data from the Professional Technician Society (PTS) website and manually enter the PCM data from the As-Built Data sheet as the NGS asks for it. After the data has been entered, continue to Step 4 above. Procedure B - NGS Alternative Method 1. Using NGS service card, select "Service Bay Functions". 2. Select PCM from the module list. 3. Select "Module Configuration". 4. Select "94-02 EECV & PTEC-By TSB". 5. Cycle ignition as directed by NGS. 6. Once the PCM initializes and the warning screen is displayed, Tire size/Axle, etc. can then be updated. Procedure C - If the VID block is not correctly programmed - but has some data stored in it, the NGS Service Function Card may not be able to configure the PCM due to the need to reprogram the module 1. Create an NGS Flash Card with the correct calibration (Tear Tag). 2. Start the reprogramming process. (you will be notified that the vehicle already has the latest calibration). 3. Select CANCEL - you will be given the opportunity to update PCM parameters (Vehicle ID block data). 4. Update the Vehicle ID block data and, it necessary, the NGS will continue to reflash the module. Procedure D - WDS Procedure if proper Programmable Module Installation was not performed and P1639/P1635 is set Using WDS with B11 or later software and ignition in OFF position: 1.

The EEPROM contains the vehicle strategy including calibration information specific to the vehicle. The IC has the capability to be reprogrammed or reflashed. This is described below by the Flash EEPROM Procedure. As part of the calibration there is an area referred to as the Vehicle Identification (VID) Block. The VID block must be programmed when replacing the PCM and is described under Programming the VID Block for a Replacement PCM. The VID block is an existing PCM can also be tailored to accommodate various hardware changes made to the vehicle since production. This is described under Making Changes to the VID Block and also under the FLASH EEPROM Procedure. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VID number, octane adjust, fuel octane. fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control, four wheel drive and manual versus non manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool. When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to reflash the PCM to reset the VID block. This is accomplished by the Flash EEPROM Procedure. Programming the VID Block for a Replacement PCM A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and in need of programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM. Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of the scan tool to retrieve data from the old PCM before removing from the vehicle. The stored data can now be downloaded to the new PCM after replacing. This same process can also be accomplished during the Flash EEPROM Procedure described below. Manual data entry must be performed if the old module is damaged and not capable of communicating. Remove and replace the old PCM. Contact the "AS BUILT" data center by fax for the data needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used. The following information will need to be faxed in: dealer name, dealer P & A code, dealer phone number, dealer fax number, technician's name, VIN and module being programmed. The necessary VID block data will then be faxed back. Enter the vehicle data string provided by the "AS BUILT" data center.

Restraint Systems > Air Bag Control Module > Component Information > Locations > Page 1018 Air Bag Control Module: Description and Operation The Restraints Control Module (RCM) performs the following functions: ^ signals the inflators to deploy the air bags in the event of a deployable crash. ^ monitors the air bag Supplemental Restraint System (SRS) for faults. ^ illuminates the air bag indicator if a fault is detected. ^ flashes the air bag indicator to indicate the Lamp Fault Code (LFC) detected. ^ communicates through the Data Link Connector (DLC) the current or historical Diagnostic Trouble Codes (DTCs). ^ signals the Generic Electronic Module (GEM) to activate a chime if the air bag indicator is not available and another SRS fault exists. NOTE: The safing sensor is internal to the RCM and is not repaired separately. The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster. When the ignition is cycled (turned OFF and then ON), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash a two-digit Lamp Fault Code (LFC). The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the Data Link Connector (DLC), using a scan tool. If the air bag indicator does not function, and a system fault is detected, the RCM will signal the GEM to activate the audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair. LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After the fault has been corrected, the next highest priority fault will be displayed. The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that an air bag deployment is required. The backup power supply will deplete its stored energy approximately 1 minute after the battery ground cable is disconnected. Sensor WARNING: THE RESTRAINTS CONTROL MODULE (RCM) ORIENTATION IS CRITICAL FOR CORRECT SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HAS BEEN INVOLVED IN A COLLISION IN WHICH THE CENTER TUNNEL AREA HAS BEEN DAMAGED, INSPECT THE MOUNTING AND BRACKET FOR DEFORMATION. IF DAMAGED, THE RCM MUST BE REPLACED WHETHER OR NOT THE AIR BAGS HAVE DEPLOYED. IN ADDITION, MAKE SURE THE AREA OF THE RCM MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION. The SRS uses four crash sensors. Two of the sensors are integral to the RCM and not separately serviceable. In addition, there are two side crash sensors mounted beneath their respective seats. The RCM is mounted to the center tunnel beneath the instrument panel. Mounting orientation is critical for correct operation of all crash sensors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Service and Repair > Removal and Installation Air Bag Control Module: Service and Repair Removal and Installation REMOVAL AND INSTALLATION WARNING: ^ TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY FRONT OR SIDE AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS AND BEFORE SERVICING, REPLACING, ADJUSTING OR STRIKING COMPONENTS NEAR THE FRONT OR SIDE AIR BAG SENSORS, SUCH AS DOORS, INSTRUMENT PANEL, CONSOLE, DOOR LATCHES, STRIKERS, SEATS AND HOOD LATCHES. ^ THE SIDE AIR BAG SENSORS ARE LOCATED AT OR NEAR THE BASE OF THE B-PILLAR. ^ TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT LEAST ONE MINUTE.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1081 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1082 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1083 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1084 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1085 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1086 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Page 1087 Heated Glass Control Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Windows; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations Heated Glass Element Relay: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations > Page 1091 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations > Page 1092 Heated Glass Element Relay: Testing and Inspection Component Testing Procedure Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions Power Window Control Module: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1097 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1105 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1106 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1107 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure.

The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration.

You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules - Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 1161 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Relays and Modules > Relays and Modules -

It consists of a float containing a magnet and a reed switch mounted in the bottom of the brake master cylinder reservoir. When the brake fluid in the brake master cylinder reservoir gets to a predetermined level, the floating magnet actuates the reed switch, causing the red brake warning indicator to illuminate. Loss of brake fluid from either the primary (front) or secondary (rear) system will cause this system to activate. If the brake fluid level warning switch is inoperative, a new brake master cylinder reservoir must be installed. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Differential Speed Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Parking Brake Release Switch > Component Information > Specifications Parking Brake Release Switch: Specifications Parking brake remote release to instrument panel bolts: 2.1-2.9 Nm (18.7-25.8 ft. lbs.) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Parking Brake Release Switch > Component Information > Specifications > Page 1272 Parking Brake Release Switch: Service and Repair Removal and Installation 1.

The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > Page 1296 Coolant Temperature Sensor/Switch (For Computer): Service and Repair REMOVAL 1.

If the temperature exceeds 130°C (265°F), the PCM disables four fuel injectors at a time. The PCM will alternate which four fuel injectors are disabled every 32 engine cycles. The four cylinders the are not being fuel injected act as air pumps to aid in cooling the engine. - If the temperature exceeds 166°C (330°F), the PCM disables all of the fuel injectors until the engine temperature drops below 153°C (308°F). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Engine Temperature Sensor > Component Information > Specifications > Page 1303 Engine Temperature Sensor: Service and Repair Removal and Installation Warning: The electrical power to the air suspension system must be shut off prior to hoisting or jacking an air suspension vehicle.

See Figure 1. Note that the revised SCDS has a different electrical connector. A jumper adapter (which is included in the parts kit) is required when replacing the old SCDS with the revised SCDS. SCDS Location In most late model year vehicles involved in this recall, the SCDS is located on the master cylinder. In early model year vehicles (1992-1998), the SCDS may be located on the master cylinder but is often found on a brake line distribution block or on the brake proportioning valve. If in doubt, just follow the metal brake lines from the master cylinder until the switch is found. ^ On early model year E-Series vehicles, the SCDS is located on the left frame rail. ^ On E-450 models only, remove the 3 screws and position the coolant degas bottle forward to allow access to the SCDS and servo. ^ On F-53 vehicles, if the SCDS is not located on the master cylinder, it may be located in a brake line junction block approximately 457 mm (18 in) below the master cylinder. It may be necessary to reposition wiring harnesses and/or remove add-on equipment in order to locate the switch. ^ On 1993 MARK VIII vehicles, the steering wheel intermediate shaft needs to be disconnected from the inside of the vehicle and the outside of the vehicle, and then positioned upwards to gain access to the SCDS. - When the intermediate steering shaft is disconnected, the steering wheel must be in the LOCK position to prevent damage to the clockspring. - During installation of the intermediate steering shaft, new bolts must be installed. Tighten the bolts to 49 Nm (36 lb-ft). ^ On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield aside. ^ On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front wheel.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 1329 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 1330 9. Cut approximately 3 mm (1/8 in) off the grease tube applicator tip. 10. Before installing the jumper harness, fill the vehicle harness end of the jumper (male pin connector end) with Motorcraft Electrical Grease II XG-15-A. See Figure 7. 11. Install the adapter jumper harness by connecting it to both the SCDS and the vehicle harness. Using the provided tie strap, secure the jumper harness to a nearby component such as the speed control cable or another wire harness. NOTICE: Be sure to apply and adequate amount of grease to the vehicle harness connector only. DO NOT apply the grease directly to the connector of the servo module. 12.

See Figure 1. Note that the revised SCDS has a different electrical connector. A jumper adapter (which is included in the parts kit) is required when replacing the old SCDS with the revised SCDS. SCDS Location In most late model year vehicles involved in this recall, the SCDS is located on the master cylinder. In early model year vehicles (1992-1998), the SCDS may be located on the master cylinder but is often found on a brake line distribution block or on the brake proportioning valve. If in doubt, just follow the metal brake lines from the master cylinder until the switch is found. ^ On early model year E-Series vehicles, the SCDS is located on the left frame rail. ^ On E-450 models only, remove the 3 screws and position the coolant degas bottle forward to allow access to the SCDS and servo. ^ On F-53 vehicles, if the SCDS is not located on the master cylinder, it may be located in a brake line junction block approximately 457 mm (18 in) below the master cylinder. It may be necessary to reposition wiring harnesses and/or remove add-on equipment in order to locate the switch. ^ On 1993 MARK VIII vehicles, the steering wheel intermediate shaft needs to be disconnected from the inside of the vehicle and the outside of the vehicle, and then positioned upwards to gain access to the SCDS. - When the intermediate steering shaft is disconnected, the steering wheel must be in the LOCK position to prevent damage to the clockspring. - During installation of the intermediate steering shaft, new bolts must be installed. Tighten the bolts to 49 Nm (36 lb-ft). ^ On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield aside. ^ On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front wheel.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 1373 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 1374 9. Cut approximately 3 mm (1/8 in) off the grease tube applicator tip. 10. Before installing the jumper harness, fill the vehicle harness end of the jumper (male pin connector end) with Motorcraft Electrical Grease II XG-15-A. See Figure 7. 11. Install the adapter jumper harness by connecting it to both the SCDS and the vehicle harness. Using the provided tie strap, secure the jumper harness to a nearby component such as the speed control cable or another wire harness. NOTICE: Be sure to apply and adequate amount of grease to the vehicle harness connector only. DO NOT apply the grease directly to the connector of the servo module. 12. Apply a 5 mm (3/16 in) high bead of Motorcraft Electrical Grease II XG-15-A across the entire width and length of the servo vehicle harness connector.

The A/C pressure sensor provides a voltage signal to the Powertrain Control Module (PCM) that is proportional to the A/C pressure. The PCM uses this information for A/C clutch control, fan control and idle speed control. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 1485 Refrigerant Pressure Sensor / Switch: Description and Operation A/C Pressure Switch A/C Cycling Switch A/C Cycling Switch The A/C cycling switch is mounted on a Schrader valve-type fitting on the top of the suction accumulator. ^ A valve depressor, located inside the threaded end of the A/C cycling switch, presses in on the Schrader valve stem. ^ This allows the suction pressure inside the suction accumulator to control the operation of the A/C cycling switch. ^ The electrical switch contacts open when the suction pressure drops to 152 - 193 kPa (22 - 28 psi). ^ The contacts close when the suction pressure rises to 276 - 324 kPa (40 - 47 psi). ^ When the A/C cycling switch contacts close, the A/C clutch field coil is energized. ^ When the A/C cycling switch contacts open, the A/C clutch field coil is deenergized and compressor operation stops. ^ The A/C cycling switch will control the A/C evaporator core pressure at a point where the plate/fin surface temperature will be maintained slightly above freezing. ^ This prevents icing of the A/C evaporator core and blockage of airflow. ^ It is not necessary to discharge the refrigerant system to remove the A/C cycling switch. Wide Open Throttle A/C Cut-Off Wide Open Throttle A/C Cut-Off Mustang The Wide Open Throttle Air Conditioning Cut-off (WAC) output is used by the PCM to disengage the A/C clutch when A/C compressor operation is not desirable. Under normal conditions, with the A/C off, the PCM will ground the WAC output, which opens the normally closed WOT A/C cut-off relay inside the constant control relay module. When the A/C demand switch is turned on, and the A/C cycling switch and A/C high pressure switch high pressure contacts are closed, voltage is supplied to the WOT A/C cut-off relay contacts and to the ACCS circuit. The voltage on the ACCS circuit indicates to the PCM that A/C is requested. The PCM will then verify that A/C clutch operation is desirable (for example, engine not cranking, overheated or not at WOT). If A/C clutch operation is desirable, the PCM will adjust idle speed as necessary and "unground" the WAC output. This closes the normally closed WOT A/C cut-off relay and allows voltage to be supplied to the A/C clutch. All Others For these applications, the wide open throttle A/C cutoff relay (may be referred to as the A/C clutch relay) is normally open. There is no direct electrical connection between the A/C switch or EATC Module and the A/C clutch. The PCM will receive a signal indicating that A/C is requested (for some applications, this message is sent through the BUS + and BUS - circuits). When A/C is requested, the PCM will check other A/C related inputs that are available (such as ACP (SW), ACCS). If these inputs indicate A/C operation is OK, and the engine conditions are OK (such as coolant temperature, engine rpm, throttle position), the PCM will ground the WAC output, closing the relay contacts and sending voltage to the A/C clutch. Air Conditioning Cycling Switch PCM Inputs Air Conditioning Cycling Switch The Air Conditioning (A/C) cycling switch may be wired to either the ACCS or ACPSW PCM input. When the A/C cycling switch opens, the PCM will turn off the A/C clutch. For information on the specific function of the A/C cycling switch, refer to Climate Control system. The A/C Cycling Switch (ACCS) circuit to the PCM provides a voltage signal which indicates when the A/C is requested. When the A/C demand switch is turned on, and both the A/C cycling switch and the high pressure contacts of the A/C high pressure switch (if equipped and in circuit) are closed, voltage is supplied to the ACCS circuit at the PCM. Refer to the applicable Wiring Diagram for vehicle specific wiring. If the ACCS signal is not received by the PCM, the PCM circuit will not allow the A/C to operate. For additional information, refer to PCM outputs, wide open throttle air conditioning cutoff. NOTE: The Town Car, Continental, LS6/LS8 and Windstar do not have a dedicated (separate) input to the PCM indicating that A/C is requested. This information is received by the PCM through the BUS + and BUS - (SCP) communication. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 1486 Air Conditioning High Pressure Switch Typical Air Conditioning Pressure Sensor Air Conditioning High Pressure Switch The A/C high pressure switch is used for additional A/C system pressure control. The A/C high pressure switch is either dual function for two-speed electric fan applications or single function for all others. For refrigerant containment control, the normally closed high pressure contacts open at a predetermined A/C pressure. This will result in the A/C turning off, preventing the A/C pressure from rising to a level that would open the A/C high pressure relief valve. For fan control, the normally open medium pressure contacts close at a predetermined A/C pressure. This grounds the ACPSW circuit input to the PCM. The PCM will then turn on the high speed fan to help reduce the pressure. The A/C pressure cutoff switch is used to interrupt A/C compressor operation in the event of high system discharge pressures. ^ The A/C pressure cutoff switch is mounted on a Schrader valve-type fitting on the high pressure side of the A/C manifold and tube. ^ A valve depressor, located inside the threaded end of the A/C pressure cutoff switch, presses on the Schrader valve stem. ^ This allows the A/C pressure cutoff switch to monitor the compressor discharge pressure. ^ When the compressor discharge pressure rises to approximately 2,896 kPa (420 psi), the switch contacts open, disengaging the A/C compressor. ^ When the pressure drops to approximately 1724 kPa (250 psi) the contacts close to allow operation of the A/C compressor. ^ It is not necessary to discharge the refrigerant system to remove the A/C pressure cutoff switch. For additional information, refer to the Wiring Diagrams. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Service and Repair > Compressor Cut-Off/Cycling Switch Refrigerant Pressure Sensor / Switch: Service and Repair Compressor Cut-Off/Cycling Switch REMOVAL 1.

On most applications the BPP switch is hard wired to the PCM and supplies battery positive voltage (B+) when the vehicle brake pedal is applied. On other applications the BPP switch signal is broadcast over the SCP link via another module to be received by the PCM. On applications where the BPP switch is hard wired to the PCM and stoplamp circuit, if all stoplamp bulbs are burned out (open), high voltage is present at the PCM due to a pull-up resistor in the PCM. This provides fail-safe operation in the event the circuit to the stoplamp bulbs has failed. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Diagrams > Page 1521 Brake Light Switch: Service and Repair REMOVAL 1.

Verify the customer concern by operating the multifunction or ignition switch. 2. Visually inspect for obvious signs of mechanical and electrical damage. 3. If the concern remains after the inspection, connect the scan tool to the Data Link Connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle: ^ check that the program card is properly installed. ^ check the connections to the vehicle. ^ check the ignition switch position. 4. If scan tool still does not communicate with the vehicle, refer to the scan tool manual. 5. Perform the DATA LINK DIAGNOSTIC TEST. If the scan tool responds with: ^ CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network. ^ NO RESP/NOT EQUIP for GEM, go to Pinpoint Test A. ^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the GEM. 6. If the DTCs retrieved arc related to the concern, go to the Generic Electronic Module (GEM) Diagnostic Trouble Code (DTC) Index to continue diagnostics. 7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling. Diagram Of Air Flow Through Throttle Body Containing MAF Sensor Hot And Cold Wire (and IAT Sensor Where Applicable) Terminals Some MAF sensors have Integrated Bypass Technology (IBT) with an integrated Intake Air Temperature (IAT) sensor. The present applications with IBT are: Focus, Escort (4V), 2.0 L Contour/Mystique, Cougar, Taurus/Sable, Windstar, Explorer/Mountaineer and E-Series. The MAF sensor is located between the air cleaner and the throttle body or inside the air cleaner assembly. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Description and Operation > Page 1716 Mass Air Flow Sensor: Service and Repair REMOVAL 1.

The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the Powertrain Control Module (PCM) and used for synchronizing the firing of sequential fuel injectors. The Coil On Plug (COP) Ignition applications also use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications Coolant Temperature Sensor/Switch (For Computer): Specifications Water temperature sensor 12-17 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1732 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General Coolant Temperature Sensor/Switch (For Computer): Description and Operation General The ECT sensor: ^ sends the PCM a signal indicating engine temperature. ^ resistance decreases as coolant temperature increases. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General > Page 1735 Coolant Temperature Sensor/Switch (For Computer): Description and Operation 2000 All (Except diesel/Propane/Villager) Engine Coolant Temperature The Engine Coolant Temperature (ECT) sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The ECT measures the temperature of the engine coolant.

By monitoring the crankshaft mounted pulse wheel, the CKP is the primary sensor for ignition information to the Powertrain Control Module (PCM). The trigger wheel has a total of 35 teeth spaced 10 degrees apart with one empty space for a missing tooth. The 6.8L ten cylinder pulse wheel has 39 teeth spaced 9 degrees apart and one 9 degree empty space for a missing tooth. By monitoring the trigger wheel, the CKP indicates crankshaft position and speed information to the PCM. By monitoring the missing tooth, the CKP is also able to identify piston travel in order to synchronize the ignition system and provide a way of tracking the angular position of the crankshaft relative to fixed reference. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Description and Operation > 2000 All (Except diesel/Propane/Villager) > Page 1743 Crankshaft Position Sensor: Description and Operation Engine Ignition The CKP sensor: ^ is a variable reluctance sensor. ^ is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft. ^ provides base timing and crankshaft speed (rpm) to the Powertrain Control Module (PCM). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Description and Operation > 2000 All (Except diesel/Propane/Villager) > Page 1744 Crankshaft Position Sensor: Description and Operation Electronic Engine Controls The CKP sensor: ^ sends the PCM a signal indicating crankshaft position. ^ is essential for calculating spark timing. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Crankshaft Position Sensor > Component Information > Description and Operation > Page 1745 Crankshaft Position Sensor: Service and Repair REMOVAL 1.

The electrical resistance of a strain gauge increases as pressure increases, and decreases as pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to pressure. Strain gauge type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. The Fuel Rail Pressure (FRP) sensor senses the pressure difference between the fuel rail and the intake manifold. The return fuel line to the fuel tank has been deleted in this type of fuel system. The differential fuel/intake manifold pressure together with measured fuel temperature provides an indication of the fuel vapors in the fuel rail. Both differential pressure and temperature feedback signals are used to control the speed of the fuel pump. The speed of the fuel pump sustains fuel rail pressure which preserve fuel in its liquid state. The dynamic range of the fuel injectors increase because of the higher rail pressure, which allows the injector pulse width to decrease. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations > Page 1759 Fuel Tank Pressure Sensor: Service Precautions CAUTION: The fuel tank pressure sensor must be disengaged from the fuel tank before it can be removed.

Supercharged 5.4L Lightning vehicles use (2) IAT sensors. Both sensors operate as described above. However, one is located before the supercharger at the air cleaner for standard OBD II/cold weather input, while a second sensor (IAT2) is located after the supercharger in the intake manifold. The IAT2 sensor located after the supercharger provides air temperature information to the PCM to control border-line spark and to help determine intercooler efficiency. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Intake Air Temperature Sensor <--> [Intake Air Temperature Sensor] > Component Information > Description and Operation > Page 1772 Intake Air Temperature Sensor: Service and Repair REMOVAL 1.

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1792 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1793 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1794 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1795 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1796 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1797 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1798 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1799 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1800 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1801 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1802 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1803 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 1804 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 1805 Heated Oxygen Sensor: Specifications Heated Oxygen Sensor 46 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 1806 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions Heated Oxygen Sensor: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1809 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1817 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1818 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1819 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1820 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1821 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1822 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 1823 Heated Oxygen Sensor: Connector Views Ford does not give the connector view. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Page 1824 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General Heated Oxygen Sensor: Description and Operation General The HO2S: ^ has the ability to create a voltage signal dependent on exhaust oxygen content. ^ provides feedback information to the PCM used to calculate fuel delivery. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General > Page 1827 Heated Oxygen Sensor: Description and Operation Heated Oxygen Sensor Heated Oxygen Sensor The Heated Oxygen Sensor (HO2S) detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. A high concentration of oxygen (lean air/fuel ratio) in the exhaust produces a low voltage signal less than 0.4 volt. A low concentration of oxygen (rich air/fuel ratio) produces a high voltage signal greater than 0.6 volt. The HO2S provides feedback to the PCM indicating air/fuel ratio in order to achieve a near stoichiometric air/fuel ratio of 14.7:1 during closed loop engine operation. The HO2S generates a voltage between 0.0 and 1.1 volts. Heated Oxygen Sensor (HO2S) Embedded with the sensing element is the HO2S heater. The heating element heats the sensor to temperatures of 800°C (1400°F). At approximately 300°C (600°F) the engine can enter closed loop operation. The VPWR circuit supplies voltage to the heater and the PCM will complete the ground when the proper conditions occur. For model year 1998 a new HO2S heater and heater control system are installed on some vehicles. The high power heater reaches closed loop fuel control temperatures. The use of this heater requires that the HO2S heater control be duty cycled, to prevent damage to the heater. The 6 ohm design is not interchangeable with new style 3.3 ohm heater. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > Page 1828 Heated Oxygen Sensor: Service and Repair EGO Sensor Wrench SPECIAL SERVICE TOOL(S) REMOVAL 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 1855 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling.

The electrical resistance of a thermistor decreases as temperature increases, and increases as temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Fuel Temperature (EFT) Sensor The EFT sensor measures the temperature of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Inertia Fuel Shutoff Switch > Component Information > Description and Operation Inertia Fuel Shutoff Switch: Description and Operation Inertia Fuel Shutoff (IFS) Switch Inertia Fuel Shutoff (IFS) Switch The Inertia Fuel Shutoff (IFS) switch is used in conjunction with the electric fuel pump. The purpose of the IFS switch is to shut off the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Sensors and Switches > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 1984 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

Toe is adjusted by the use of the front wheel spindle tie rod adjusting sleeve. The three basic alignment angles are camber, caster, and toe. Camber and toe affect tire wear and directional stability, caster affects directional stability only. Camber, caster and toe settings change when the vehicle is loaded. The specifications given are static settings with the vehicle unloaded. Camber is the inward or outward tilting of the wheels at the top. When the wheels tilt out at the top the camber is positive (+). When the wheels tilt in at the top the camber is negative (-). The amount of camber is measured in degrees from vertical. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Specifications > Page 2099 Steering axis inclination (included angle) is the center line drawn through the ball joints when viewed from the front. Caster is the tilting of the steering axis either forward or backward from vertical. A backward tilt is positive (+) and a forward tilt is negative Wheel Track Toe is a measurement of how much the front of the wheels are turned in or out from the straight-ahead position. When the wheels are turned in, toe is positive (+)(toe in). When the wheels are turned out, toe is negative (-)(toe out). Toe is measured in degrees, from side to side and totaled. Toe should only be checked and adjusted after the camber and caster have been set to the proper specifications. Dogtracking Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Specifications > Page 2100 By design the vehicle has a front track that is wider at the front than the rear. Front track is the distance between the two front tires; rear track is the distance between the two rear tires. Dogtracking is the condition where the rear axle is not square to the chassis. Heavily crowned roads may give the illusion of dogtracking. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Service and Repair > Camber and Caster Adjustment Alignment: Service and Repair Camber and Caster Adjustment 1. Remove the alignment plate. 1. Remove the upper suspension arm nuts. 2. Remove the alignment plate. 2. Install the washers and the adjusting nuts. 3. Note: A pry bar can be used between the front suspension upper arm and the frame pocket to aid in moving the arm. To increase caster and camber, use the following steps. 1. To increase caster move the front of the front suspension upper arm outboard and move the rear of the front suspension upper arm inboard. 2. To increase camber, move the front suspension upper arm outboard equally. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Service and Repair > Camber and Caster Adjustment > Page 2103 4. To decrease caster and camber, use the following steps. 1. To decrease caster, move the front of the front suspension upper arm inboard and move the rear of the front suspension upper arm outboard. 2. To decrease camber, move the front suspension upper arm inboard equally. 5. Note: Each increment of the notches on the frame pocket represents 0.4 degree. Set the caster and camber to specifications. If a caster increase of 1.2 degrees is required, move the front of the front suspension upper arm outboard by 3 notches and move the rear of the front suspension upper arm inboard by 3 notches, since one notch represents 0.4 degree. 6. Tighten the upper suspension arm nuts. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Service and Repair > Camber and Caster Adjustment > Page 2104 Alignment: Service and Repair Toe Adjustment 1. Start the engine and center the steering wheel. 2. Turn the engine off, and hold the steering wheel in the "straightforward" position by attaching a rigid link from the steering wheel to the brake pedal. 3. Check the toe settings; follow the equipment manufacturer's instructions. 4. Hold the tie-rod end while loosening the toe set jam nuts. 5. Rotate the front wheel spindle tie-rod adjusting sleeve to desired position. 6. Note: Whenever the toe set jam nuts are loosened for toe adjustment, the nut and tie-rod threads must be cleaned and lubricated. Tighten the jam nuts as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Alignment > System Information > Service and Repair > Camber and Caster Adjustment > Page 2105 1.

For additional information, refer to the Compression Pressure Limit Chart. Compression Pressure Limit Chart Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 2150 Compression Check: Testing and Inspection General Remarks Note: Removing fuses and disconnecting electrical components causes the Powertrain Control Module (PCM) to log an error message. After the measurements have been carried out this error message should be cleared from memory by connecting to PDU. Note: Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted). The compression pressure should be checked with the engine at operating temperature. Check The Compression Pressure WARNING: On manual transmissions shift the transmission into neutral. On automatic transmission vehicles, select "P". Failure to follow these instructions may result in personal injury. 1. Remove the fuel pump relay. 2. Start the engine-the engine will start, run for a few seconds then stall. 3. Remove the spark plugs. 4. Install the compression tester. 5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading. 6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes. 7. Install the components in reverse order, observing the specified tightening torques. 8. Reset the PCM fault memory. Interpretation of the Results The indicated compression pressure are considered within specification if the lowest reading cylinder is within 75% of the highest reading. CAUTION: If engine oil is sprayed into the combustion chamber, after carrying out the measurement run the engine at 2000 rpm for about 15 minutes, in order to burn the oil and prevent damage to the catalytic converter. If the measurement on one or more cylinders is much lower than the specified value, spray some engine oil into the combustion chamber and repeat the compression measurement. If the reading greatly improves, the piston rings are damaged. If the reading stays the same, the cause is either damaged valve seats or valve stem seals. If the measurements for two cylinders next to each other arc both too low then it is very likely that the cylinder head gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the engine oil. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Valve Clearance > System Information > Specifications Valve Clearance: Specifications The manufacturer indicates that this vehicle has hydraulic lifters or adjusters and therefore does not require adjustment. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Locations Drive Belt: Locations Accessory Drive 4.6L, 5.4L(2V), 5.4L(4V) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Locations > Page 2157 Drive Belt: Diagrams Accessory Drive 4.6L, 5.4L(2V), 5.4L(4V) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Locations > Page 2158 Drive Belt: Description and Operation Accessory Drive 4.6L, 5.4L(2V), 5.4L(4V) The accessory drive consists of the: - drive belt (8620). - generator pulley. - power steering pump pulley. - crankshaft pulley. - A/C clutch pulley. - belt idler pulley. - drive belt tensioner. - water pump pulley.

Service as required. 2. Rotate the drive belt tensioner and check for a binding or frozen condition. Replace components as required. V-Ribbed Belt With Cracks (Acceptable) V-Ribbed Belt With Chunks Of Rib Missing (Not Acceptable) Drive Belt Misalignment CAUTION: Incorrect drive belt installation will cause excessive drive belt wear and may cause the drive belt to come off the drive pulleys. Non-standard replacement drive belts may track differently or improperly. If a replacement drive belt tracks improperly, replace it with an original equipment drive belt to avoid performance failure or loss of drive belt. With the engine running, check drive belt tracking. If the (A) edge of the drive belt rides beyond the edge of the pulleys, noise and premature wear may occur. Make sure the (B) drive belt rides correctly on the pulley. If a drive belt tracking condition exists, proceed with the following: Visually check the drive belt tensioner for damage, especially the mounting pad surface. If the drive belt tensioner is not installed correctly, the mounting surface pad will be out of position. This will result in chirp and squeal noises. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2163 - With the engine running, visually observe the grooves in the pulleys (not the pulley flanges or the pulley forward faces) for excessive wobble. Replace components as required. - Check all accessories, mounting brackets and the drive belt tensioner for any interference that would prevent the component from mounting properly. Correct any interference condition and recheck the drive belt tracking. - Tighten all accessories, mounting brackets, and drive belt tensioner retaining hardware to specification. Recheck the drive belt tracking. Drive Belt Noise/Flutter Note: Tensioner is shown in free-state position against arm travel stops. Drive Belt Tensioner/Belt Length Indicator Drive belt chirp occurs due to pulley misalignment or excessive pulley runout. It can be the result of a damaged pulley or an improperly aligned pulley. To correct, determine the area where the noise comes from. Check each of the pulleys in that area with a straightedge to the crankshaft pulley, look for accessory pulleys out of position in the fore/aft direction or at an angle to the straightedge. Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions, such as: engine start up, rapid engine acceleration, or A/C clutch engagement. Drive belt squeal can occur under certain conditions: If the A/C discharge pressure goes above specifications: + the A/C system is overcharged. + the A/C condenser core airflow is blocked. - If the A/C OFF equalized pressure (the common discharge and suction pressure that occurs after several minutes) exceeds specifications. - If any of the accessories are damaged, have a worn or damaged bearing, internal torsional resistance above normal. All accessories should be rotatable by hand in the unloaded condition. If not, inspect the accessory. - If fluid gets on the drive belt. This includes power steering fluid, engine coolant, engine oil or air conditioning system lubricant. If fluid does get on the drive belt during service, clean the drive belt with soap and water and thoroughly rinse with clean water. The drive belt does not have to be Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2164 replaced if no apparent damage has occurred. - Note: The drive belt tensioner arm should rotate freely without binding. If the drive belt is too long. A drive belt that is too long will allow the drive belt tensioner arm to go all the way to the arm travel stop under certain load conditions, which will release tension to the drive belt. If the drive belt tensioner indicator is outside the installation wear range window, replace the drive belt. - If the drive belt tensioner is worn or damaged. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Drive Belt > Component Information > Testing and Inspection > Page 2165 Drive Belt: Adjustments Note: Drive belt tension is not adjustable.

ISSUE The majority of repeat heater core leaks are due to high flow rate or use of poor quality coolant. However, electrolysis should also be checked, especially when repeat repairs have occurred. ACTION If the heater core is leaking, review the location of the leakage and check the condition of the coolant. SERVICE PROCEDURE 1. Review the location of the leakage and check the condition of the coolant: a. If leaks are found on the inlet (or outlet) tubes entering / exiting the heater core, it is most likely due to due to high flow rate - replace the Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Hoses > Heater Hose > Component Information > Technical Service Bulletins > Customer Interest for Heater Hose: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 2204 heater core and install a restrictor in the heater hose closest to the engine block, reference Workshop Manual, Section 412. b. If leaks are found in the body of the heater core itself, and does not appear to be the result of physical damage like contact or puncture, check the coolant for possible electrolysis. Testing For Electrolysis Check for voltage in the cooling system by touching the negative contact of a voltmeter to the battery ground or a known good ground and suspend the positive lead in the coolant, making sure it is in contact with the coolant but not touching any metal part of the radiator or cooling system. Both AC and DC voltages must be checked. Vehicles normally have DC voltages; however, a faulty engine block heater or faulty diode in the alternator can produce AC voltages. It is understood that coolant is lost due to heater core failure but try to obtain a voltage reading on the old coolant in the engine block before addition to or replacement of. To keep more coolant from exiting the heater core clamp off heater core lines and measure coolant in the engine block. Try not to dilute the original coolant with new coolant during testing if possible. 1. Determine whether coolant condition is acceptable. a. Remove both cables from the battery and ensure they do not contact each other or the vehicle. b. Touch negative lead of voltmeter to engine ground and positive lead in the coolant. NOTE POSITIVE TEST PROBE IS IN THE COOLANT FOR TESTING. c. Check the voltage in the cooling system. If less than or equal to 0.4 volts (V) OK, reconnect battery cables and proceed to Step 2. d. If greater than 0.4 V, flush cooling system thoroughly. e. Recheck voltage less than or equal to 0.4 V. f. Reconnect battery cables. g. Refill the system with appropriate Motorcraft® engine coolant. 2. Check for loose or missing grounds at static conditions. a. Turn off all accessories. Turn ignition on but do not start engine. b. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. c. Voltage less than or equal to 0.4 V on all grounds OK. d. Any one greater than 0.4 V, check and clean ground cable connections. e. Check accessories without using the on off switch on the vehicle instrument panel, use a jumper wire to ground. f. Plug in engine block heater, if equipped, and test. g. Recheck voltage less than or equal to 0.4 V. h. Unplug engine block heater, if equipped. 3. Check for loose, missing, or inadequate grounds. a. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. b. Crank engine but do not start. c. Monitor voltage while cranking. less than or equal to 0.4 V OK d.

ISSUE The majority of repeat heater core leaks are due to high flow rate or use of poor quality coolant. However, electrolysis should also be checked, especially when repeat repairs have occurred. ACTION If the heater core is leaking, review the location of the leakage and check the condition of the coolant. SERVICE PROCEDURE 1. Review the location of the leakage and check the condition of the coolant: a. If leaks are found on the inlet (or outlet) tubes entering / exiting the heater core, it is most likely due to due to high flow rate - replace the Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Hoses > Heater Hose > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Heater Hose: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 2211 heater core and install a restrictor in the heater hose closest to the engine block, reference Workshop Manual, Section 412. b. If leaks are found in the body of the heater core itself, and does not appear to be the result of physical damage like contact or puncture, check the coolant for possible electrolysis. Testing For Electrolysis Check for voltage in the cooling system by touching the negative contact of a voltmeter to the battery ground or a known good ground and suspend the positive lead in the coolant, making sure it is in contact with the coolant but not touching any metal part of the radiator or cooling system. Both AC and DC voltages must be checked. Vehicles normally have DC voltages; however, a faulty engine block heater or faulty diode in the alternator can produce AC voltages. It is understood that coolant is lost due to heater core failure but try to obtain a voltage reading on the old coolant in the engine block before addition to or replacement of. To keep more coolant from exiting the heater core clamp off heater core lines and measure coolant in the engine block. Try not to dilute the original coolant with new coolant during testing if possible. 1. Determine whether coolant condition is acceptable. a. Remove both cables from the battery and ensure they do not contact each other or the vehicle. b. Touch negative lead of voltmeter to engine ground and positive lead in the coolant. NOTE POSITIVE TEST PROBE IS IN THE COOLANT FOR TESTING. c. Check the voltage in the cooling system. If less than or equal to 0.4 volts (V) OK, reconnect battery cables and proceed to Step 2. d. If greater than 0.4 V, flush cooling system thoroughly. e. Recheck voltage less than or equal to 0.4 V. f. Reconnect battery cables. g. Refill the system with appropriate Motorcraft® engine coolant. 2. Check for loose or missing grounds at static conditions. a. Turn off all accessories. Turn ignition on but do not start engine. b. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. c. Voltage less than or equal to 0.4 V on all grounds OK. d. Any one greater than 0.4 V, check and clean ground cable connections. e. Check accessories without using the on off switch on the vehicle instrument panel, use a jumper wire to ground. f. Plug in engine block heater, if equipped, and test. g. Recheck voltage less than or equal to 0.4 V. h. Unplug engine block heater, if equipped. 3. Check for loose, missing, or inadequate grounds. a. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. b. Crank engine but do not start. c. Monitor voltage while cranking. less than or equal to 0.4 V OK d. If greater than 0.4 V, ground or repair starter. e. Start engine and run at about 2000 rpm. f. Turn on all accessories including those customer only uses occasionally such as CB radio, cell phone, etc. g. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Hoses > Heater Hose > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Heater Hose: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 2212 h.

The condenser to evaporator tube contains high pressure liquid refrigerant upstream of the A/C evaporator core orifice. The A/C manifold and tube is attached to the A/C compressor with O-ring seals and has the following features: ^ The upstream side contains low pressure refrigerant gas. ^ The downstream side contains high pressure refrigerant gas. ^ An integral non-serviceable muffler and a serviceable high pressure A/C charge port valve are located on the downstream side. ^ The downstream side also contains a fitting used to mount the A/C pressure cutoff switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C pressure cutoff switch can be removed without discharging the A/C system. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Service and Repair > Auxiliary Climate Control Hose/Line HVAC: Service and Repair Auxiliary Climate Control Front Auxiliary Evaporator Outlet and Inlet Line REMOVAL NOTE: The 5/8 inch front auxiliary evaporator outlet line is shown, the 3/8 inch front auxiliary evaporator inlet line is similar. 1.

ISSUE This TSB article describes Ford Motor Company's position on the use of propylene glycol-based engine coolants. ACTION Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Technical Service Bulletins > Engine Coolant - Propylene Glycol Recommendations > Page 2296 Ford Motor Company does not recommend nor endorse the use of engine coolants made with propylene glycol in Ford vehicles. Ford Motor Company currently recommends the use of ethylene glycol-based engine coolants. Published information suggests that engine coolants made with propylene glycol may provide engine cooling performance equivalent to engine coolants made with ethylene glycol. However, different brands of engine coolant provide varying corrosion protection for the cooling system. Ford does not have performance data for the multitude of engine coolants available in the aftermarket and therefore cannot recommend the use of any coolant except those sold by Ford Customer Service Division. Consult the vehicle's Owner's Guide to determine the appropriate Ford Customer Service Division coolant for the vehicle. Furthermore, claims of toxicological and environmental advantages of propylene glycol over ethylene glycol may be misleading. When significant new information is developed, Ford will review this policy. Ford Motor Company specifications recommend that vehicles be maintained using certain ethylene glycol-based engine coolants. Those specifications do not refer to engine coolants made with propylene glycol. Although the Ford New Vehicle Limited Warranty is not automatically voided upon the use of a coolant made with propylene glycol, if such use results in damage to the vehicle or its components, the cost of repairing the damage would not be covered by the Ford New Vehicle Limited Warranty.

Ozone Depletion Scientific research performed over the past 15 years links the release of chlorofluorocarbons (CFC)s, also know by the trade name Freon) into the atmosphere to ozone depletion. When CFCs are released into the atmosphere, they eventually reach the ozone layer located in the stratosphere where they react with and destroy ozone molecules. Harmful Effects Ozone depletion and the corresponding increase in UV radiation has been shown to lead to higher incidents of cancer as well as global warming. When viewed from a global perspective, ozone depletion holds an enormous potential for damage. Upper Level Vs. Ground Level Ozone Confusion often arises when we hear about the necessity of the ozone layer and ground level ozone. The ozone layer existing high above the earth is beneficial but the same compound, when located at ground level, is harmful to humans, animals, crops and vegetation. Ground level ozone is a component of smog and forms when hydrocarbons (HC) react with nitrogen oxides (NOx) in the presence of sunlight and heat. Montreal Protocol In response to the growing body of evidence demonstrating the detrimental effects of (CFC)s, 24 countries and the European community met in Montreal, Canada, in 1987 to establish standards for the control of (CFC)s. Since that time, a total of 132 countries have become signatories to this agreement leading to an end of production of R12 in December, 1995, in all developed countries. As established by the Montreal Protocol, R12 production in developed countries has ceased. Clean Air Act The United States Congress, acting in response to the Montreal Protocol, banned production of (CFC)s by the year 2000. Congress also amended the Clean Air Act in an effort to control both the production and use of (CFC)s for refrigerant applications including mobile vehicle air conditioning systems.

Connect the R-134a A/C Refrigerant Center to the low and high-pressure service gauge port valves. 2. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer. 3. Once the service center has recovered the vehicle A/C system refrigerant, close the service center inlet valve (if so equipped). Then switch off the power supply. 4. Allow the vehicle A/C system to remain closed for about two minutes. Observe the system vacuum level as shown on the gauge. If the pressure does not rise, disconnect the recovery station hose(s). 5. If the system pressure rises, repeat steps 2 through 5 until the vacuum level remains stable for two minutes. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fluids > Refrigerant Oil > Component Information > Specifications > Fluid Type Specifications Refrigerant Oil: Fluid Type Specifications PAG Refrigerant Compressor Oil (R-134a Systems) Ford Part Number................................................................................................................................. ................F7AZ-19589-DA (Motorcraft YN-12-C) Ford Specification................................................................................................................................. ...................................................WSH-M1C231-B Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fluids > Refrigerant Oil > Component Information > Specifications > Page 2346 Refrigerant Oil: Service and Repair CAUTION: During normal A/C operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If certain components of the system are removed, some of the refrigerant oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part. 1. Rotate the A/C compressor shaft six to eight revolutions while collecting oil in a clean measuring device. ^ If the amount of oil drained from the old A/C compressor is between 85 - 142 ml (3 - 5 ounces), pour the same amount plus 30 ml (1 ounce) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor. ^ If the amount of oil that was removed from the old A/C compressor is greater than 142 ml (5 ounces), pour the same amount drained of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor. ^ If the amount of oil that was removed from the old A/C compressor is less than 85 ml (3 ounces), pour 85 ml (3 ounces) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor.

This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. 1. Turn all vehicle accessories OFF. 2. Turn the ignition switch to OFF. 3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 5. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. The side impact sensors (if equipped) are located at or near the base of the B-pillars. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). 6. Disconnect the battery ground cable (14301) and wait at least one minute. Repowering Procedure Warning: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards. 1. Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected. 2. Turn the ignition switch from OFF to ON. 3. Install the RCM fuse F22 (10A) to the CJB and close the cover. Warning: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected. 4. Connect the battery ground cable. 5. Prove out the supplemental restraint system (SRS) as follows: Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either: fail to light. - remain lit continuously. - flash. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 2373 The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either: fail to light. - remain lit continuously. - flash. The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 2384 Air Bag(s) Arming and Disarming: Service and Repair Air Bag System Reconnect Checklist The checklist below should be completed following diagnosis or repair of any air bag system concern. 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2405 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2406 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2407 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2408 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2409 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 2410 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box Fuse: Application and ID Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box > Page 2413 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box > Page 2414 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box > Page 2415 Fuse: Application and ID Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box > Page 2416 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Application and ID > Battery Junction Box > Page 2417 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box Fuse Block: Locations Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box > Page 2422 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box > Page 2423 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box > Page 2424 Fuse Block: Locations Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box > Page 2425 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Locations > Battery Junction Box > Page 2426 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions Fuse Block: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 2429 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 2437 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 2438 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 2439 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Fuses

This bulletin is authored and endorsed by Hunter, Michelin, Goodyear, Continental/General, Hankook, Bridgestone/Firestone and Pirelli. Items addressed are software upgrades, road test (exercise tires), assembly center verification and warranty restrictions. This type of equipment can be a valuable tool to improve customer satisfaction when used as a vibration repair tool. This type of equipment can also provide a high level of customer satisfaction when used as an assembly too! when the customer has purchased new wheels/tires in the "Around-the-Wheel" program. ACTION The Hunter GSP9700/9712 road force measurement tool is NOT to be used for determining if a tire or wheel meets a specification. It can be used as a service diagnostic tool to minimize road force variation of the tire/wheel assembly. The tool such as the Hunter GSP97OO can approximate the low point of the "'1heel and the high point of the tire. This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly road force variation. This will minimize the contribution to vibration from the tire/wheel assembly.

The wheel resting on the ground could cause the vehicle to move. - The tire and wheel must always be correctly matched. It is very important to determine the size of each component before any assembly operations commence. Do not mount a 16-inch tire on a 16.5-inch wheel. Failure to adhere to these instructions can result in an explosive separation and cause serious bodily injury or death. Do not mount a 16.5-inch tire on a 16-inch wheel. The tire can come off without warning. - Aftermarket aerosol tire sealants are extremely flammable. Always question the customer to make sure these products have not been used. - Use only wheels and wheel nuts that have been designed for current model year ford trucks. Aftermarket wheels or wheel nuts may not fit or function correctly, and can cause personal injury or damage the vehicle. - Always wear safety goggles or a face shield when performing any work with tire and wheel assemblies. - Retighten the wheel nuts at 800 km (500 miles) after any wheel change or any time the wheel nuts are loosened. - Failure to retighten wheel nuts at the mileage specified can allow wheels to come off while the vehicle is in motion, possibly causing loss of vehicle control and collision. CAUTION: Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong detergents. Use Custom Bright Metal Cleaner .8A-19522-A or equivalent meeting Ford specification ESR-M5B194-B. - Reduce the air pressure as much as possible by pushing the valve core plunger in prior to removing the valve core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Page 2509 Wheels: Description and Operation WARNING: Do not mix different types of tires, such as radial, bias, or bias-belted, on the same vehicle except in emergencies (temporary spare usage). Vehicle handling can be seriously affected and can result in loss of control. Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures. Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear. Replacement tires should follow the recommended: tire sizes. - speed rating. - load range. - radial construction type. Use of any other tire size or type may seriously affect: ride. - handling. - speedometer/odometer calibration. - vehicle ground clearance. - tire clearance between the body and chassis. - Wheel bearing life. - brake cooling. New wheels need to be installed when: bent. - dented. - heavily rusted. - leaking. - they have elongated wheel hub bolt holes. - they have excessive lateral or radial runout. The Expedition uses a two-piece wheel nut, containing the nut and a washer. Wheel and tire assemblies are attached by five noncentering wheel nuts. When balancing wheels and tires, use T-type balancing weights. The spare tire is mounted under the frame. The valve stem should. be on the top side of the tire to reduce the possibility of accidental valve stem air leakage. To equalize tire wear, rotate the tires periodically. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Service and Repair > Wheel and Tire Wheels: Service and Repair Wheel and Tire Removal 1.

For additional information, refer to the Compression Pressure Limit Chart. Compression Pressure Limit Chart Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Compression Check > System Information > Specifications > Page 2554 Compression Check: Testing and Inspection General Remarks Note: Removing fuses and disconnecting electrical components causes the Powertrain Control Module (PCM) to log an error message. After the measurements have been carried out this error message should be cleared from memory by connecting to PDU. Note: Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted). The compression pressure should be checked with the engine at operating temperature. Check The Compression Pressure WARNING: On manual transmissions shift the transmission into neutral. On automatic transmission vehicles, select "P". Failure to follow these instructions may result in personal injury. 1. Remove the fuel pump relay. 2. Start the engine-the engine will start, run for a few seconds then stall. 3. Remove the spark plugs. 4. Install the compression tester. 5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading. 6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes. 7. Install the components in reverse order, observing the specified tightening torques. 8. Reset the PCM fault memory. Interpretation of the Results The indicated compression pressure are considered within specification if the lowest reading cylinder is within 75% of the highest reading. CAUTION: If engine oil is sprayed into the combustion chamber, after carrying out the measurement run the engine at 2000 rpm for about 15 minutes, in order to burn the oil and prevent damage to the catalytic converter. If the measurement on one or more cylinders is much lower than the specified value, spray some engine oil into the combustion chamber and repeat the compression measurement. If the reading greatly improves, the piston rings are damaged. If the reading stays the same, the cause is either damaged valve seats or valve stem seals. If the measurements for two cylinders next to each other arc both too low then it is very likely that the cylinder head gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the engine oil. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Camshaft Bearing > Component Information > Specifications Camshaft Bearing: Specifications Camshaft Bearing Cap Bolts 71-106 in.lb Sequence - Romeo Engine --Sequence - Windsor Engine --- Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Camshaft Bearing > Component Information > Specifications > Page 2559 Camshaft Bearing: Service and Repair Refer to Engine Service and Repair for "General Procedures" and "Disassembly and Assembly of Subassemblies".

Verify customer concern by running the engine. 2. Inspect the drive belt for chunking, fraying and wear. 3. Check the drive belt for correct routing. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2723 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2724 Drive Belt: Component Tests and General Diagnostics Belt Tension Note: Drive belt tension is not adjustable. The drive belt tensioner automatically adjusts drive belt tension. Belt Tensioner, Automatic Check the automatic drive belt tensioner: 1. With the engine off, check for proper drive belt routing. Service as required. 2. Rotate the drive belt tensioner and check for a binding or frozen condition. Replace components as required. V-Ribbed Belt With Cracks (Acceptable) V-Ribbed Belt With Chunks Of Rib Missing (Not Acceptable) Drive Belt Misalignment CAUTION: Incorrect drive belt installation will cause excessive drive belt wear and may cause the drive belt to come off the drive pulleys. Non-standard replacement drive belts may track differently or improperly. If a replacement drive belt tracks improperly, replace it with an original equipment drive belt to avoid performance failure or loss of drive belt. With the engine running, check drive belt tracking. If the (A) edge of the drive belt rides beyond the edge of the pulleys, noise and premature wear may occur. Make sure the (B) drive belt rides correctly on the pulley. If a drive belt tracking condition exists, proceed with the following: Visually check the drive belt tensioner for damage, especially the mounting pad surface. If the drive belt tensioner is not installed correctly, the mounting surface pad will be out of position. This will result in chirp and squeal noises. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2725 - With the engine running, visually observe the grooves in the pulleys (not the pulley flanges or the pulley forward faces) for excessive wobble. Replace components as required. - Check all accessories, mounting brackets and the drive belt tensioner for any interference that would prevent the component from mounting properly. Correct any interference condition and recheck the drive belt tracking. - Tighten all accessories, mounting brackets, and drive belt tensioner retaining hardware to specification. Recheck the drive belt tracking. Drive Belt Noise/Flutter Note: Tensioner is shown in free-state position against arm travel stops. Drive Belt Tensioner/Belt Length Indicator Drive belt chirp occurs due to pulley misalignment or excessive pulley runout. It can be the result of a damaged pulley or an improperly aligned pulley. To correct, determine the area where the noise comes from. Check each of the pulleys in that area with a straightedge to the crankshaft pulley, look for accessory pulleys out of position in the fore/aft direction or at an angle to the straightedge. Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions, such as: engine start up, rapid engine acceleration, or A/C clutch engagement. Drive belt squeal can occur under certain conditions: If the A/C discharge pressure goes above specifications: + the A/C system is overcharged. + the A/C condenser core airflow is blocked. - If the A/C OFF equalized pressure (the common discharge and suction pressure that occurs after several minutes) exceeds specifications. - If any of the accessories are damaged, have a worn or damaged bearing, internal torsional resistance above normal. All accessories should be rotatable by hand in the unloaded condition. If not, inspect the accessory. - If fluid gets on the drive belt. This includes power steering fluid, engine coolant, engine oil or air conditioning system lubricant. If fluid does get on the drive belt during service, clean the drive belt with soap and water and thoroughly rinse with clean water. The drive belt does not have to be Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 2726 replaced if no apparent damage has occurred. - Note: The drive belt tensioner arm should rotate freely without binding. If the drive belt is too long. A drive belt that is too long will allow the drive belt tensioner arm to go all the way to the arm travel stop under certain load conditions, which will release tension to the drive belt. If the drive belt tensioner indicator is outside the installation wear range window, replace the drive belt. - If the drive belt tensioner is worn or damaged. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Testing and Inspection > Page 2727 Drive Belt: Adjustments Note: Drive belt tension is not adjustable.

ISSUE Some vehicles equipped with the Romeo built 4.6L 2V engine or 5.4L 2V Windsor and 5.4L Supercharged engine may exhibit an oil leak or oil weepage from the cylinder head gasket at the right hand rear or the left hand front of the engine. Oil weepage is not considered detrimental to engine performance or durability. An oil leak may be caused by metal chip debris lodged between the head gasket and the block, chip debris between the cylinder head and the head gasket, or by damage to the cylinder head sealing surface that occurred during the manufacturing process. ACTION Once an oil leak is verified with a black light test at the head gasket joint, replacement of the head gasket can be performed. If the head was damaged by chip contamination, the head should be replaced. A revised "Service-Only" gasket is now released for both of these cases.

The revised "Service-Only" gasket has a feature by which the embossed sealing area does not follow the same sealing path as the original gasket. This area is surrounding the High Pressure Oil Feed (HPOF) area. It is triangular in shape and is found in the rear of the passenger side cylinder head, or, in the front of the drivers side cylinder head (Figure 1 and Figure 2). Required for service are: ^ A straightedge (machine flatness toleranced to 0.0002" per foot in length) (available from Snap-On or as provided by Ford Motor Company) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Cylinder Head Gasket > Component Information > Technical Service Bulletins > Customer Interest: > 03-6-2 > Mar > 03 > Engine - Oil Leak From R/H Cylinder Head Gasket > Page 2862 ^ Motorcraft Silicone Gasket Remover (ZC-30) ^ Metal Surface Prep (ZC-31) ^ Service-only gasket (3U7Z-6051-BA for drivers side and/or 3U7Z-6051-AA for passenger side) with the new embossed area The engine should be allowed to cool before removing the head or warpage may occur in deck flatness. The cylinder head and block decks should be cleaned before performing a flatness check. Dark metal stains below the surface of the metal are normal. Do not attempt to polish off the stains with grinders or scrapers. Use a plastic scraper (or plastic ice scraper or equivalent) to pull away any residual silicone RTV with ZC-30 and ZC-31 applied in sequence. The Workshop Manual and Service Labor Time Standards have been recently updated for both cars and truck using 4.6L 2V and 5.4L 2V and Supercharged 5.4L engines. These include instructions to remove the engine prior to removing the cylinder head. Service Labor Time Standards allow for extra time in engine removal and cylinder head deck leak repair out of vehicle. Cylinder Head Kits are available on most applications. Refer to the current Parts Catalog Listing for applicability.

ISSUE Some vehicles equipped with the Romeo built 4.6L 2V engine or 5.4L 2V Windsor and 5.4L Supercharged engine may exhibit an oil leak or oil weepage from the cylinder head gasket at the right hand rear or the left hand front of the engine. Oil weepage is not considered detrimental to engine performance or durability. An oil leak may be caused by metal chip debris lodged between the head gasket and the block, chip debris between the cylinder head and the head gasket, or by damage to the cylinder head sealing surface that occurred during the manufacturing process. ACTION Once an oil leak is verified with a black light test at the head gasket joint, replacement of the head gasket can be performed. If the head was damaged by chip contamination, the head should be replaced. A revised "Service-Only" gasket is now released for both of these cases.

AFTER REMOVING THE HEAD BOLTS, WITHDRAW THE HEAD FROM THE ENGINE COMPARTMENT. USE EXTREME CARE NOTING THAT THE GASKET SURFACE OF THE HEAD COULD BE DAMAGED ON THE WAY OUT OF THE VEHICLE IF ALLOWED TO HIT AGAINST OTHER ENGINE COMPONENTS. ONCE REMOVED, PLACE THE HEAD ON A BENCH, GASKET SIDE UP, USING A PIECE OF CLEAN CARDBOARD ON THE BENCH SURFACE UNDERNEATH. DO NOT SLIDE THE HEAD GASKET SURFACE ALONG THE BENCHTOP OR DAMAGE WILL OCCUR. NOTE SOME ENGINES REQUIRE A "DE-TORQUING" PROCEDURE OF THE CYLINDER HEAD BOLTS. CONSULT WITH THE APPROPRIATE MODEL YEAR WORKSHOP MANUAL FIRST, AS THIS PROCEDURE IS USUALLY DONE ON FOUR-VALVE ENGINES. HOWEVER, ALL ALUMINUM HEADS ARE PRONE TO WARPAGE DURING REMOVAL IF TAKEN OFF WHEN HOT OR WARM. THE ENGINE SHOULD BE COOLED SUFFICIENTLY BY THE TIME THE HEADS ARE ACCESSIBLE DURING TEARDOWN. ALLOW AN ADEQUATE COOL DOWN PERIOD. NOTE IN SOME ENGINE APPLICATIONS, IT MAY BE NECESSARY TO "RUBBER BAND" A FEW OF THE HEAD BOLTS TOGETHER DUE TO TIGHT CLEARANCES OF THE HEAD NEAR HEATER/AC PLENUMS AND THE BODY COWL. THIS WILL ALLOW THE BOLTS TO CLEAR THE BLOCK DECK AS THE HEAD IS WITHDRAWN FROM THE VEHICLE. Place CLEAN shop towels over the cylinder block bores to prevent further contamination from reaching internal parts and surfaces. If a towel is to be removed, do it SLOWLY . Debris collected on the towel can fall on the engine if care is not exercised as it is removed. Gasket surfaces are machined to near-mirror surface quality. Scratches, dents, gouges, and other impressions may allow oil, coolant, and compression gases to leak into other sealed cavities and/or the atmosphere. Surface imperfections deteriorate the head gasket's ability to seal effectively. Contamination on these surfaces will cause leaks from "shimming" the head even under full head bolt torque. Contamination will also cause marks on the polished gasket surface, creating a leak path. Inspection For Damage and Cleaning Procedure The overall straightness of the cylinder head and block face is held within very tight specification. Defects known as "waviness" or "depressions" cannot be surface machined out with ordinary equipment. Machining must meet manufacturer's specification on surface finish quality and be less than 0.001" inch (0.025 mm) level as measured under a known quality straightedge using a feeler gauge. If the engine has been overheated the cylinder head may have been damaged or warped. Re-surfacing will not correct this damage. The head must not contain any impressions on its sealing surface deeper than 0.001" (0.025 mm). There must not be any scratches or gouges present, especially those which track to another sealing cavity or to the atmosphere. Ensure that the mating cylinder block surface is completely free of solid contamination, corrosion, and fluids. Use Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA or equivalent, to rid the surface of any material, which could later interfere with the gasket's sealing ability. WARNING UNDER NO CIRCUMSTANCES ARE ANY ALUMINUM GASKET SURFACES TO BE CLEANED USING RAZOR BLADES, ROTARY ABRASIVE DEVICES INCLUDING ROLOC AND 3M BRANDED SCOTCHBRITE PRODUCTS, ROTARY WIRE BRUSHES, SINGLE HANDLED WIRE BRUSHES, HAND ABRASIVE SUCH AS SANDPAPER OR EMERY CLOTH, OR ANY CARBON STEEL BLADE. THESE TOOLS ARE PROVEN TO CUT AND DAMAGE ALUMINUM AND WILL DISRUPT THE POLISHED FINISH. ABRASIVE PARTICLES ARE ALSO SUSCEPTIBLE TO ENTERING THE ENGINE CAVITIES AND MAY CAUSE INTERNAL ENGINE DAMAGE. THE ONLY TOOLS ACCEPTABLE ARE PLASTIC AND WOOD SCRAPERS COMBINED WITH USE OF MOTORCRAFT METAL SURFACE CLEANER, F4AZ-19A536-RA, OR EQUIVALENT SOLVENT. The original head bolts are to be discarded. Only new head bolts are acceptable for use in a head gasket repair. Use of old bolts can cause clamp load failure because they were stretched from the last torquing procedure either from the plant or a previous field repair. The new head bolt shanks and threads should be thoroughly cleaned, dried, and lightly lubricated. Oil the bolts and let oil drip for a minimum of 5 minutes. Use of too much oil may cause hydraulic lockup in the bolt hole. The corresponding bolt holes in the cylinder block must be free of contamination consisting of dirt particles, coolant, and oil. Bolts can mechanically or hydraulically lock on top of these materials and cause for poor clamping of the cylinder head gasket. Use very lightly compressed air to blow out the bolt holes. Use care to prevent debris from scattering over the internal engine surfaces. To clean the cylinder block gasket surface, a plastic or wood scraper in combination with Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA, or equivalent solvent can be used with a portable shop vacuum. Move the scraper toward the vacuum nozzle to direct loosened material quickly away from the block surface. It is not necessary to expect aluminum head surfaces to be shiny and bright after the vehicle has been in service. Sanding, scraping, or polishing will create surface depressions that cause leaks. The surface is expected to be flat within 0.001" (0.025 mm) and free of dirt, metal chips, and liquid contaminants. Any staining of the metal surface is considered normal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Cylinder Head Gasket > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Cylinder Head Gasket: > 02-1-4 > Jan > 02 > Engine Head Gasket - Approved Replacement Procedures > Page 2883 Machining of aluminum heads and blocks is an unacceptable field practice for quality control purposes of flatness and surface finish standards. Removing material will also raise the risk of internal reciprocating components striking each other, as well as changing the emissions calibration of the engine. Machining practices of aluminum blocks and heads are not reimbursable. Ford Remanufacturers are authorized to perform this procedure and have the necessary equipment to put the specified surface finish on the head within original factory limits. Installation Onto the Cylinder Block Surface WARNING ANY GASKET SEALING AIDS WHICH ARE NOT LIMITED TO, AND INCLUDE AVIATION CEMENT, COPPER SPRAYS, OR GLUES ARE NOT TO BE USED. THE GASKET MUST BE FITTED DRY WITHOUT SUPPLEMENTAL SEALING AIDS. ATTEMPTS TO SEAL WITH THESE COMPOUNDS WILL CAUSE HEAD SHIMMING AND/OR NEW LEAK PATHS. THESE COMPOUNDS HAVE ALSO BEEN KNOWN TO CAUSE EMISSIONS SENSORS TO FAIL THEREBY TRIPPING FAULT CODES IN THE PCM. Ensure that all surfaces of the cylinder block, cylinder head, and gasket are fully free of any solid or liquid contamination and have been prepared for assembly using Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA, or equivalent solvent. Also ensure that any residual dirt on the engine was removed successfully from the surrounding areas of the block to head face of the head and the block. Using Workshop Manual procedures, assemble the head to the block carefully. Do not allow the gasket surfaces to scrape or bang against other engine parts. The head may pick up material along the way, if this is allowed. Once in place, with dowels properly aligned to the head and ensuring that the head is fully square, seated, and resting on the block deck in a level condition, install new "torque-to-yield" cylinder head bolts to a finger tight condition. Refer to the appropriate model year Workshop Manual for the procedure to torque the head bolts in the correct sequence and at the intervals specified. Failure to follow these instructions may result in a warped head, and damaged head bolt threads. Do not use "cheater pipes" on torque wrenches. Use a known quality, calibrated torque wrench. Pull evenly and steady on each bolt. Do not exert side pressures on the bolt hex, which can disrupt the integrity of the bolt head and give a false reading on the final torque value of the fastener. Once the engine is fully reassembled, be sure that fluid levels have been topped off as required for the operation. When the engine is ready for starting, ensure that the engine 6i1 pump is (was) primed properly and is in a "ready to start" condition with all engine oil galleys having been charged with oil. WARNING DO NOT RACE THE ENGINE UPON INITIAL STARTUP. MAINTAIN ENGINE IDLE TO BUILD OIL PRESSURE. USE OF A MECHANICAL PRESSURE GAUGE WILL ENSURE THAT OIL FLOW HAS DEVELOPED ON THE PUMP'S PRESSURE SIDE. A DEFECTIVE GAUGE OR LIGHT IN THE INSTRUMENT PANEL WILL NOT VERIFY PRESSURE HAS BEEN OBTAINED. SEVERE INTERNAL ENGINE DAMAGE WILL RESULT IF PRESSURE IS NOT OBSERVED AND STEADILY MAINTAINED. Allow a warm up period, which brings the engine to normal operating temperature. Check for leaks around the gasket joints of the head, front cover, and associated component parts. The vehicle should be road tested within normal guidelines to raise the engine to operating temperature and verify the repair is sound. Shut down the engine, allow for a cool-down and drain-back period to enable fluids to return to levels. Check fluid levels using owner guide recommendations (dipstick, sight gages, etc.). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Cylinder Head Gasket > Component Information > Technical Service Bulletins > All Other Service Bulletins for Cylinder Head Gasket: > 06-18-16 > Sep > 06 > Engine - Reman Engine Head Gasket Identification Cylinder Head Gasket: All Technical Service Bulletins Engine - Reman Engine Head Gasket Identification TSB 06-18-16 09/18/06 IDENTIFYING THE CORRECT REPLACEMENT HEAD GASKET FOR CERTAIN REMANUFACTURED ENGINES - SERVICE TIP FORD: 1999-2006 Mustang, Mustang, Mustang, Mustang, Mustang, Mustang 2000-2005 Thunderbird 2001-2005 Taurus 2001-2006 Crown Victoria, Crown Victoria 2005 Five Hundred, Freestyle 1997-2005 Expedition 1997-2006 E-Series, Explorer, F-150, F-Super Duty 1999-2003 Windstar 1999-2004 F-53 Motorhome Chassis 2000-2005 Excursion 2001-2003 Explorer Sport 2001-2005 Escape, Escape, Explorer Sport Trac, Ranger 2004-2005 Freestar, Freestar 2006 F-53 Motorhome Chassis LINCOLN: 2000-2006 Lincoln LS 2001-2002 Continental 2001-200 Town Car 1998-2004 Navigator, Navigator 2003-2004 Aviator 2006 Mark LT MERCURY: 2001 Cougar 2001-2005 Sable 2001-2006 Grand Marquis 2003-2006 Marauder 2005 Montego 1997-2006 Mountaineer 2004-2005 Monterey 2005 Mariner ISSUE On various vehicles when servicing the head gasket on certain Ford remanufactured engines, it is critical to determine the type of remanufactured engine that is being serviced, in order to identify the correct replacement gasket.

Inspection For Damage and Cleaning Procedure The overall straightness of the cylinder head and block face is held within very tight specification. Defects known as "waviness" or "depressions" cannot be surface machined out with ordinary equipment. Machining must meet manufacturer's specification on surface finish quality and be less than 0.001" inch (0.025 mm) level as measured under a known quality straightedge using a feeler gauge. If the engine has been overheated the cylinder head may have been damaged or warped. Re-surfacing will not correct this damage. The head must not contain any impressions on its sealing surface deeper than 0.001" (0.025 mm). There must not be any scratches or gouges present, especially those which track to another sealing cavity or to the atmosphere. Ensure that the mating cylinder block surface is completely free of solid contamination, corrosion, and fluids. Use Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA or equivalent, to rid the surface of any material, which could later interfere with the gasket's sealing ability. WARNING UNDER NO CIRCUMSTANCES ARE ANY ALUMINUM GASKET SURFACES TO BE CLEANED USING RAZOR BLADES, ROTARY ABRASIVE DEVICES INCLUDING ROLOC AND 3M BRANDED SCOTCHBRITE PRODUCTS, ROTARY WIRE BRUSHES, SINGLE HANDLED WIRE BRUSHES, HAND ABRASIVE SUCH AS SANDPAPER OR EMERY CLOTH, OR ANY CARBON STEEL BLADE. THESE TOOLS ARE PROVEN TO CUT AND DAMAGE ALUMINUM AND WILL DISRUPT THE POLISHED FINISH. ABRASIVE PARTICLES ARE ALSO SUSCEPTIBLE TO ENTERING THE ENGINE CAVITIES AND MAY CAUSE INTERNAL ENGINE DAMAGE. THE ONLY TOOLS ACCEPTABLE ARE PLASTIC AND WOOD SCRAPERS COMBINED WITH USE OF MOTORCRAFT METAL SURFACE CLEANER, F4AZ-19A536-RA, OR EQUIVALENT SOLVENT. The original head bolts are to be discarded. Only new head bolts are acceptable for use in a head gasket repair. Use of old bolts can cause clamp load failure because they were stretched from the last torquing procedure either from the plant or a previous field repair. The new head bolt shanks and threads should be thoroughly cleaned, dried, and lightly lubricated. Oil the bolts and let oil drip for a minimum of 5 minutes. Use of too much oil may cause hydraulic lockup in the bolt hole. The corresponding bolt holes in the cylinder block must be free of contamination consisting of dirt particles, coolant, and oil. Bolts can mechanically or hydraulically lock on top of these materials and cause for poor clamping of the cylinder head gasket. Use very lightly compressed air to blow out the bolt holes. Use care to prevent debris from scattering over the internal engine surfaces. To clean the cylinder block gasket surface, a plastic or wood scraper in combination with Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA, or equivalent solvent can be used with a portable shop vacuum. Move the scraper toward the vacuum nozzle to direct loosened material quickly away from the block surface. It is not necessary to expect aluminum head surfaces to be shiny and bright after the vehicle has been in service. Sanding, scraping, or polishing will create surface depressions that cause leaks. The surface is expected to be flat within 0.001" (0.025 mm) and free of dirt, metal chips, and liquid contaminants. Any staining of the metal surface is considered normal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Cylinder Head Gasket > Component Information > Technical Service Bulletins > All Other Service Bulletins for Cylinder Head Gasket: > 02-1-4 > Jan > 02 > Engine Head Gasket - Approved Replacement Procedures > Page 2897 Machining of aluminum heads and blocks is an unacceptable field practice for quality control purposes of flatness and surface finish standards. Removing material will also raise the risk of internal reciprocating components striking each other, as well as changing the emissions calibration of the engine. Machining practices of aluminum blocks and heads are not reimbursable. Ford Remanufacturers are authorized to perform this procedure and have the necessary equipment to put the specified surface finish on the head within original factory limits. Installation Onto the Cylinder Block Surface WARNING ANY GASKET SEALING AIDS WHICH ARE NOT LIMITED TO, AND INCLUDE AVIATION CEMENT, COPPER SPRAYS, OR GLUES ARE NOT TO BE USED. THE GASKET MUST BE FITTED DRY WITHOUT SUPPLEMENTAL SEALING AIDS. ATTEMPTS TO SEAL WITH THESE COMPOUNDS WILL CAUSE HEAD SHIMMING AND/OR NEW LEAK PATHS. THESE COMPOUNDS HAVE ALSO BEEN KNOWN TO CAUSE EMISSIONS SENSORS TO FAIL THEREBY TRIPPING FAULT CODES IN THE PCM. Ensure that all surfaces of the cylinder block, cylinder head, and gasket are fully free of any solid or liquid contamination and have been prepared for assembly using Motorcraft Metal Surface Cleaner, F4AZ-19A536-RA, or equivalent solvent. Also ensure that any residual dirt on the engine was removed successfully from the surrounding areas of the block to head face of the head and the block. Using Workshop Manual procedures, assemble the head to the block carefully. Do not allow the gasket surfaces to scrape or bang against other engine parts. The head may pick up material along the way, if this is allowed. Once in place, with dowels properly aligned to the head and ensuring that the head is fully square, seated, and resting on the block deck in a level condition, install new "torque-to-yield" cylinder head bolts to a finger tight condition. Refer to the appropriate model year Workshop Manual for the procedure to torque the head bolts in the correct sequence and at the intervals specified. Failure to follow these instructions may result in a warped head, and damaged head bolt threads. Do not use "cheater pipes" on torque wrenches. Use a known quality, calibrated torque wrench. Pull evenly and steady on each bolt. Do not exert side pressures on the bolt hex, which can disrupt the integrity of the bolt head and give a false reading on the final torque value of the fastener. Once the engine is fully reassembled, be sure that fluid levels have been topped off as required for the operation. When the engine is ready for starting, ensure that the engine 6i1 pump is (was) primed properly and is in a "ready to start" condition with all engine oil galleys having been charged with oil. WARNING DO NOT RACE THE ENGINE UPON INITIAL STARTUP. MAINTAIN ENGINE IDLE TO BUILD OIL PRESSURE. USE OF A MECHANICAL PRESSURE GAUGE WILL ENSURE THAT OIL FLOW HAS DEVELOPED ON THE PUMP'S PRESSURE SIDE. A DEFECTIVE GAUGE OR LIGHT IN THE INSTRUMENT PANEL WILL NOT VERIFY PRESSURE HAS BEEN OBTAINED. SEVERE INTERNAL ENGINE DAMAGE WILL RESULT IF PRESSURE IS NOT OBSERVED AND STEADILY MAINTAINED. Allow a warm up period, which brings the engine to normal operating temperature. Check for leaks around the gasket joints of the head, front cover, and associated component parts. The vehicle should be road tested within normal guidelines to raise the engine to operating temperature and verify the repair is sound. Shut down the engine, allow for a cool-down and drain-back period to enable fluids to return to levels. Check fluid levels using owner guide recommendations (dipstick, sight gages, etc.). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Front Crankshaft Seal > Component Information > Specifications Front Crankshaft Seal: Specifications Special Tools Removal 1.

After the measurements have been carried out this error message should be cleared from memory by connecting to PDU. Note: Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted). The compression pressure should be checked with the engine at operating temperature. Check The Compression Pressure WARNING: On manual transmissions shift the transmission into neutral. On automatic transmission vehicles, select "P". Failure to follow these instructions may result in personal injury. 1. Remove the fuel pump relay. 2. Start the engine-the engine will start, run for a few seconds then stall. 3. Remove the spark plugs. 4. Install the compression tester. 5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading. 6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes. 7. Install the components in reverse order, observing the specified tightening torques. 8. Reset the PCM fault memory. Interpretation of the Results The indicated compression pressure are considered within specification if the lowest reading cylinder is within 75% of the highest reading. CAUTION: If engine oil is sprayed into the combustion chamber, after carrying out the measurement run the engine at 2000 rpm for about 15 minutes, in order to burn the oil and prevent damage to the catalytic converter. If the measurement on one or more cylinders is much lower than the specified value, spray some engine oil into the combustion chamber and repeat the compression measurement. If the reading greatly improves, the piston rings are damaged. If the reading stays the same, the cause is either damaged valve seats or valve stem seals. If the measurements for two cylinders next to each other arc both too low then it is very likely that the cylinder head gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the engine oil. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Valve Clearance > System Information > Specifications Valve Clearance: Specifications The manufacturer indicates that this vehicle has hydraulic lifters or adjusters and therefore does not require adjustment. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Water Pump > Component Information > Specifications > Water Pump Water Pump: Specifications Water pump bolts 15 - 22 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Water Pump > Component Information > Specifications > Water Pump > Page 3019 Water Pump: Specifications Water pump pulley bolts 15 - 22 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Engine > Water Pump > Component Information > Specifications > Page 3020 Water Pump: Service and Repair Removal and Installation 1.

ISSUE This TSB article describes Ford Motor Company's position on the use of propylene glycol-based engine coolants. ACTION Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Technical Service Bulletins > Engine Coolant - Propylene Glycol Recommendations > Page 3026 Ford Motor Company does not recommend nor endorse the use of engine coolants made with propylene glycol in Ford vehicles. Ford Motor Company currently recommends the use of ethylene glycol-based engine coolants. Published information suggests that engine coolants made with propylene glycol may provide engine cooling performance equivalent to engine coolants made with ethylene glycol. However, different brands of engine coolant provide varying corrosion protection for the cooling system. Ford does not have performance data for the multitude of engine coolants available in the aftermarket and therefore cannot recommend the use of any coolant except those sold by Ford Customer Service Division. Consult the vehicle's Owner's Guide to determine the appropriate Ford Customer Service Division coolant for the vehicle. Furthermore, claims of toxicological and environmental advantages of propylene glycol over ethylene glycol may be misleading. When significant new information is developed, Ford will review this policy. Ford Motor Company specifications recommend that vehicles be maintained using certain ethylene glycol-based engine coolants. Those specifications do not refer to engine coolants made with propylene glycol. Although the Ford New Vehicle Limited Warranty is not automatically voided upon the use of a coolant made with propylene glycol, if such use results in damage to the vehicle or its components, the cost of repairing the damage would not be covered by the Ford New Vehicle Limited Warranty.

The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > Page 3053 Coolant Temperature Sensor/Switch (For Computer): Service and Repair REMOVAL 1.

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. 1. Inspect for evidence of coolant leakage at the heater water hose to heater core attachments. A coolant leak in the heater water hose could follow the heater core tube to the heater core and appear as a leak in the heater core. NOTE: Testing of returned heater cores reveals that a large percentage of heater cores are good and did not require installation of a new heater core. If a heater core leak is suspected, the heater core must be tested by following the plugged heater core component test before the heater core pressure test. Carry out a system inspection by checking the heater system thoroughly. 2. Check the integrity of the heater water hose clamps. NOTE: Spring-type clamps are installed as original equipment. Installation and overtightening of non-specification clamps can cause leakage at the heater water hose connection and damage the heater core. Heater Core Plugged WARNING: THE HEATER CORE INLET HOSE WILL BECOME TOO HOT TO HANDLE IF THE SYSTEM IS WORKING CORRECTLY. 1. Check to see that the engine coolant is at the proper level. 2. Start the engine and turn on the heater. 3. When the engine coolant reaches operating temperature, feel the heater core outlet hose to see if it is hot. If it is not hot: ^ the heater core may have an air pocket. ^ the heater core may be plugged. ^ the thermostat may not be working correctly. Heater Core-Pressure Test Use the radiator/heater core pressure tester to carry out the pressure test. 1. Drain the coolant from the cooling system. NOTE: Due to space limitations, a bench test may be necessary for pressure testing. 2. Disconnect the heater water hoses from the heater core. 3. Install a short piece of heater water hose, approximately 101 mm (4 inches) long on each heater core tube. 4. Fill the heater core and heater water hoses with water and install plug BT-7422-B and adapter BT-7422-A from the radiator/heater core pressure tester in the heater water hose ends. Secure the heater water hoses, plug and adapter with hose clamps. 5. Attach the pump and gauge assembly from the radiator/heater core pressure tester to the adapter. 6. Close the bleed valve at the base of the gauge. Pump 241 kPa (35 psi) of air pressure into the heater core. 7. Observe the pressure gauge for a minimum of three minutes. 8. If the pressure drops, check the heater water hose connections to the core tubes for leaks. If the heater water hoses do not leak, remove the heater core from the vehicle and carry out the bench test. Heater Core Bench Test 1. Remove the heater core from the vehicle. 2. Drain all of the coolant from the heater core. 3. Connect the 101 mm (4 inch) test heater water hoses with plug and adapter to the core tubes. Then connect the radiator/heater core pressure tester to the adapter. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Core > Component Information > Description and Operation > Page 3093 4.

ISSUE The majority of repeat heater core leaks are due to high flow rate or use of poor quality coolant. However, electrolysis should also be checked, especially when repeat repairs have occurred. ACTION If the heater core is leaking, review the location of the leakage and check the condition of the coolant. SERVICE PROCEDURE 1. Review the location of the leakage and check the condition of the coolant: a. If leaks are found on the inlet (or outlet) tubes entering / exiting the heater core, it is most likely due to due to high flow rate - replace the Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Hose > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Heater Hose: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 3114 heater core and install a restrictor in the heater hose closest to the engine block, reference Workshop Manual, Section 412. b. If leaks are found in the body of the heater core itself, and does not appear to be the result of physical damage like contact or puncture, check the coolant for possible electrolysis. Testing For Electrolysis Check for voltage in the cooling system by touching the negative contact of a voltmeter to the battery ground or a known good ground and suspend the positive lead in the coolant, making sure it is in contact with the coolant but not touching any metal part of the radiator or cooling system. Both AC and DC voltages must be checked. Vehicles normally have DC voltages; however, a faulty engine block heater or faulty diode in the alternator can produce AC voltages. It is understood that coolant is lost due to heater core failure but try to obtain a voltage reading on the old coolant in the engine block before addition to or replacement of. To keep more coolant from exiting the heater core clamp off heater core lines and measure coolant in the engine block. Try not to dilute the original coolant with new coolant during testing if possible. 1. Determine whether coolant condition is acceptable. a. Remove both cables from the battery and ensure they do not contact each other or the vehicle. b. Touch negative lead of voltmeter to engine ground and positive lead in the coolant. NOTE POSITIVE TEST PROBE IS IN THE COOLANT FOR TESTING. c. Check the voltage in the cooling system. If less than or equal to 0.4 volts (V) OK, reconnect battery cables and proceed to Step 2. d. If greater than 0.4 V, flush cooling system thoroughly. e. Recheck voltage less than or equal to 0.4 V. f. Reconnect battery cables. g. Refill the system with appropriate Motorcraft® engine coolant. 2. Check for loose or missing grounds at static conditions. a. Turn off all accessories. Turn ignition on but do not start engine. b. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. c. Voltage less than or equal to 0.4 V on all grounds OK. d. Any one greater than 0.4 V, check and clean ground cable connections. e. Check accessories without using the on off switch on the vehicle instrument panel, use a jumper wire to ground. f. Plug in engine block heater, if equipped, and test. g. Recheck voltage less than or equal to 0.4 V. h. Unplug engine block heater, if equipped. 3. Check for loose, missing, or inadequate grounds. a. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. b. Crank engine but do not start. c. Monitor voltage while cranking. less than or equal to 0.4 V OK d. If greater than 0.4 V, ground or repair starter. e. Start engine and run at about 2000 rpm. f. Turn on all accessories including those customer only uses occasionally such as CB radio, cell phone, etc. g. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Hose > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Heater Hose: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 3115 h.

The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > Page 3170 Coolant Temperature Sensor/Switch (For Computer): Service and Repair REMOVAL 1.

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3206 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3207 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3208 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3209 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3210 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3211 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3212 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3213 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3214 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3215 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3216 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3217 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3218 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Page 3219 Catalytic Converter: Specifications Three way catalytic converter to exhaust manifold nuts 30 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Page 3220 Generic Catalyst and Exhaust System Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Page 3221 Catalytic Converter: Description and Operation Overview Generic Catalyst and Exhaust System The Catalytic Converter and Exhaust Systems work together to control the release of harmful engine exhaust emissions into the atmosphere. The engine exhaust gas consists mainly of Nitrogen (N), Carbon Dioxide (CO2) and Water Vapor (H2O). However, it also contains Carbon Monoxide (CO), Oxides Of Nitrogen (NOx), Hydrogen (H), and various unburned Hydrocarbons (HCs). CO, NOx, and HCs are major air pollutants, and their emission into the atmosphere must be controlled. The exhaust system generally consists of an exhaust manifold, front exhaust pipe, upstream Heated Oxygen Sensor (HO2S), rear exhaust pipe, downstream HO2S, a muffler and an exhaust tailpipe. The catalytic converter is installed between the front and rear exhaust pipes. Catalytic converter efficiency is monitored by the On Board Diagnostic (OBD II) system. (Refer to OBD II Monitors to Catalyst Efficiency Monitor-Federal Test Procedure for specific information.) Catalytic Converter A catalyst is a material that remains unchanged when it initiates and increases the speed of a chemical reaction. A catalyst will also enable a chemical reaction to occur at a lower temperature. The concentration of exhaust gas products released to the atmosphere must be controlled. The catalytic converter assists in this task. It contains a catalyst in the form of a specially treated honeycomb structure saturated with catalytically active precious metals. As the exhaust gases come in contact with the catalyst, they are changed into mostly harmless products. The catalyst initiates and speeds up heat producing chemical reactions of the exhaust gas components so they are used up as much as possible. Exhaust System The purpose of the exhaust system is to convey engine emissions from the exhaust manifold to the atmosphere. Engine exhaust emissions are directed from the engine exhaust manifold to the catalytic converter through the front exhaust pipe. An HO2S is mounted on the front exhaust pipe before the catalyst. The catalytic converter reduces the concentration of Carbon Monoxide (CO), unburned Hydrocarbons (HCs) and Oxides Of Nitrogen (NOx) in the exhaust emissions to an acceptable level. The reduced exhaust emissions are directed from the catalytic converter to a muffler through the rear exhaust pipe. Another HO2S is mounted on the rear exhaust pipe. Lastly, the exhaust emissions are directed to the atmosphere through an exhaust tailpipe. HARDWARE The downstream HO2S may be located after the light off catalyst or underbody catalyst. The underbody catalyst may be in-line with the light off catalyst, or the underbody catalyst may be common to two light off catalysts, forming a "Y" pipe configuration. For an exact configuration of the catalyst and exhaust system, refer to Exhaust System. Three Way Catalytic Converter The Three Way Catalytic (TWC) converter contains either Platinum (Pt) and Rhodium (Rh) or Palladium (Pd) and Rhodium (Rh). The TWC converter catalyzes the oxidation reactions of unburned HCs and CO and the reduction reaction of NOx. The three-way conversion can br brst accomplished by always operating the engine air fuel/ratio at or close to stoichiometry. Exhaust Manifold/Runners The exhaust manifold runners collect exhaust gases from engine cylinders. The number of exhaust manifolds and exhaust manifold runners depends on Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Page 3222 the engine configuration and number of cylinders. Exhaust Pipes Exhaust pipes are usually treated during manufacturing with an anti-corrosive coating agent to increase the life of the product. The pipes serve as guides for the flow of exhaust gases from the engine exhaust manifold through the catalytic converter and the muffler. Upstream Heated and Downstream Heated Oxygen Sensors The HO2S provide the Powertrain Control Module (PCM) with voltage and frequency information related to the oxygen content of the exhaust gas. (Refer to the PCM Inputs for a description of how the H02S operates.) In addition to providing the PCM with indications of how rich/lean the engine is operating, the upstream HO2S signal serves as an input to the H02S monitor. The downstream HO2S signal is an input to the Catalyst Efficiency monitor. (Refer to the OBD II Monitors for specific information on these monitors.) Muffler Mufflers are usually treated during manufacturing with an anti-corrosive coating agent to increase the life of the product. The muffler reduces the level of noise produced by the engine, and it also reduces the noise produced by exhaust gases as they travel from the catalytic converter to the atmosphere. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Technical Service Bulletins > Page 3223 Catalytic Converter: Service and Repair Removal and Installation All vehicles 1.

The EEPROM contains the vehicle strategy including calibration information specific to the vehicle. The IC has the capability to be reprogrammed or reflashed. This is described below by the Flash EEPROM Procedure. As part of the calibration there is an area referred to as the Vehicle Identification (VID) Block. The VID block must be programmed when replacing the PCM and is described under Programming the VID Block for a Replacement PCM. The VID block is an existing PCM can also be tailored to accommodate various hardware changes made to the vehicle since production. This is described under Making Changes to the VID Block and also under the FLASH EEPROM Procedure. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VID number, octane adjust, fuel octane. fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control, four wheel drive and manual versus non manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool. When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to reflash the PCM to reset the VID block. This is accomplished by the Flash EEPROM Procedure. Programming the VID Block for a Replacement PCM A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and in need of programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM. Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of the scan tool to retrieve data from the old PCM before removing from the vehicle. The stored data can now be downloaded to the new PCM after replacing. This same process can also be accomplished during the Flash EEPROM Procedure described below. Manual data entry must be performed if the old module is damaged and not capable of communicating. Remove and replace the old PCM. Contact the "AS BUILT" data center by fax for the data needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used. The following information will need to be faxed in: dealer name, dealer P & A code, dealer phone number, dealer fax number, technician's name, VIN and module being programmed. The necessary VID block data will then be faxed back. Enter the vehicle data string provided by the "AS BUILT" data center. Refer to the Worldwide Diagnostic System users manual for details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Relays and Modules -

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications Coolant Temperature Sensor/Switch (For Computer): Specifications Water temperature sensor 12-17 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 3337 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General Coolant Temperature Sensor/Switch (For Computer): Description and Operation General The ECT sensor: ^ sends the PCM a signal indicating engine temperature. ^ resistance decreases as coolant temperature increases. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General > Page 3340 Coolant Temperature Sensor/Switch (For Computer): Description and Operation 2000 All (Except diesel/Propane/Villager) Engine Coolant Temperature The Engine Coolant Temperature (ECT) sensor is a thermistor device in which resistance changes with temperature.

The electrical resistance of a strain gauge increases as pressure increases, and decreases as pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to pressure. Strain gauge type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. The Fuel Rail Pressure (FRP) sensor senses the pressure difference between the fuel rail and the intake manifold. The return fuel line to the fuel tank has been deleted in this type of fuel system. The differential fuel/intake manifold pressure together with measured fuel temperature provides an indication of the fuel vapors in the fuel rail. Both differential pressure and temperature feedback signals are used to control the speed of the fuel pump. The speed of the fuel pump sustains fuel rail pressure which preserve fuel in its liquid state. The dynamic range of the fuel injectors increase because of the higher rail pressure, which allows the injector pulse width to decrease. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations > Page 3364 Fuel Tank Pressure Sensor: Service Precautions CAUTION: The fuel tank pressure sensor must be disengaged from the fuel tank before it can be removed.

The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The EOT measures the temperature of the engine oil. The EOT sensor is similar in construction to the Engine Coolant Temperature (ECT) sensor. On some applications, EOT input to the PCM is used to initiate a soft engine shutdown. This prevents engine damage from occurring as a result of high oil temperature. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis Technical Service Bulletin # 01-9-7 Date: 010514 Emissions/Engine Controls - Driveability Diagnosis Article No. 01-9-7 05/14/01 DRIVEABILITY - H025 (HEATED OXYGEN SENSOR), CATALYST, AND FUEL SYSTEM MONITORS - SERVICE TIPS - OBD II VEHICLES ONLY FORD: 1994-1997 THUNDERBIRD 1994-2001 MUSTANG 1995-2001 CROWN VICTORIA 1996-1997 PROBE 1996-2000 CONTOUR 1996-2001 ESCORT, TAURUS 2000-2001 FOCUS 1994-1997 F SUPER DUTY, F-250 HD, F-350 1995-2001 ECONOLINE, RANGER, WINDSTAR 1996 BRONCO 1996-1997 AEROSTAR 1996-2001 EXPLORER 1997-2001 EXPEDITION, F-150, F-250 LD 1999-2001 SUPER DUTY F SERIES 2000-2001 EXCURSION 2001 ESCAPE LINCOLN: 1995-2001 CONTINENTAL, TOWN CAR 1996-1998 MARK VIII 2000-2001 LS 1998-2001 NAVIGATOR MERCURY: 1994-1997 COUGAR 1995-2001 GRAND MARQUIS 1996-1999 TRACER 1996-2000 MYSTIQUE 1996-2001 SABLE 1999-2001 COUGAR 1997-2001 MOUNTAINEER ISSUE This article is intended to be an aide in diagnosing conditions related to Heated Oxygen Sensor (HO2S), Catalyst, and Fuel System Monitor related Diagnostic Trouble Codes (DTCs).

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3397 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3398 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3399 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3400 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3401 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3402 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3403 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3404 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3405 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3406 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3407 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3408 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3409 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 3410 Heated Oxygen Sensor: Specifications Heated Oxygen Sensor 46 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 3411 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions Heated Oxygen Sensor: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3414 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3422 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3423 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3424 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3425 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3426 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3427 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3428 Heated Oxygen Sensor: Connector Views Ford does not give the connector view. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Page 3429 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General Heated Oxygen Sensor: Description and Operation General The HO2S: ^ has the ability to create a voltage signal dependent on exhaust oxygen content. ^ provides feedback information to the PCM used to calculate fuel delivery. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General > Page 3432 Heated Oxygen Sensor: Description and Operation Heated Oxygen Sensor Heated Oxygen Sensor The Heated Oxygen Sensor (HO2S) detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. A high concentration of oxygen (lean air/fuel ratio) in the exhaust produces a low voltage signal less than 0.4 volt. A low concentration of oxygen (rich air/fuel ratio) produces a high voltage signal greater than 0.6 volt. The HO2S provides feedback to the PCM indicating air/fuel ratio in order to achieve a near stoichiometric air/fuel ratio of 14.7:1 during closed loop engine operation. The HO2S generates a voltage between 0.0 and 1.1 volts. Heated Oxygen Sensor (HO2S) Embedded with the sensing element is the HO2S heater. The heating element heats the sensor to temperatures of 800°C (1400°F). At approximately 300°C (600°F) the engine can enter closed loop operation. The VPWR circuit supplies voltage to the heater and the PCM will complete the ground when the proper conditions occur. For model year 1998 a new HO2S heater and heater control system are installed on some vehicles. The high power heater reaches closed loop fuel control temperatures. The use of this heater requires that the HO2S heater control be duty cycled, to prevent damage to the heater. The 6 ohm design is not interchangeable with new style 3.3 ohm heater. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > Page 3433 Heated Oxygen Sensor: Service and Repair EGO Sensor Wrench SPECIAL SERVICE TOOL(S) REMOVAL 1.

The sensor housing has a three-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and increases connector durability. The TP sensor is mounted on the throttle body. As the TP sensor is rotated by the throttle shaft, four operating conditions are determined by the PCM from the TP. Those conditions are closed throttle (includes idle or deceleration), part throttle (includes cruise or moderate acceleration), wide open throttle (includes maximum acceleration or de-choke on crank), and throttle angle rate. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Description and Operation > Page 3451 Throttle Position Sensor: Service and Repair REMOVAL 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 3460 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling. Diagram Of Air Flow Through Throttle Body Containing MAF Sensor Hot And Cold Wire (and IAT Sensor Where Applicable) Terminals Some MAF sensors have Integrated Bypass Technology (IBT) with an integrated Intake Air Temperature (IAT) sensor. The present applications with IBT are: Focus, Escort (4V), 2.0 L Contour/Mystique, Cougar, Taurus/Sable, Windstar, Explorer/Mountaineer and E-Series. The MAF sensor is located between the air cleaner and the throttle body or inside the air cleaner assembly. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Description and Operation > Page 3491 Mass Air Flow Sensor: Service and Repair REMOVAL 1.

The electrical resistance of a thermistor decreases as temperature increases, and increases as temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Fuel Temperature (EFT) Sensor The EFT sensor measures the temperature of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Inertia Fuel Shutoff Switch > Component Information > Description and Operation Inertia Fuel Shutoff Switch: Description and Operation Inertia Fuel Shutoff (IFS) Switch Inertia Fuel Shutoff (IFS) Switch The Inertia Fuel Shutoff (IFS) switch is used in conjunction with the electric fuel pump. The purpose of the IFS switch is to shut off the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle. Refer to the Owner Guide for the location of the IFS. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > General Throttle Position Sensor: Description and Operation General The TP sensor: ^ sends the PCM a signal indicating the throttle plate angle. ^ is the main input to the PCM from the driver. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > General > Page 3504 Throttle Position Sensor: Description and Operation Throttle Position Sensor Throttle Position Sensor Throttle Position (TP) Sensor The Throttle Position (TP) sensor is a rotary potentiometer sensor that provides a signal to the PCM that is linearly proportional to the throttle plate/shaft position. The sensor housing has a three-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and increases connector durability. The TP sensor is mounted on the throttle body. As the TP sensor is rotated by the throttle shaft, four operating conditions are determined by the PCM from the TP. Those conditions are closed throttle (includes idle or deceleration), part throttle (includes cruise or moderate acceleration), wide open throttle (includes maximum acceleration or de-choke on crank), and throttle angle rate. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > Page 3505 Throttle Position Sensor: Service and Repair REMOVAL 1.

Compression Pressure Limit Chart Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 3575 Compression Check: Testing and Inspection General Remarks Note: Removing fuses and disconnecting electrical components causes the Powertrain Control Module (PCM) to log an error message. After the measurements have been carried out this error message should be cleared from memory by connecting to PDU. Note: Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted). The compression pressure should be checked with the engine at operating temperature. Check The Compression Pressure WARNING: On manual transmissions shift the transmission into neutral. On automatic transmission vehicles, select "P". Failure to follow these instructions may result in personal injury. 1. Remove the fuel pump relay. 2. Start the engine-the engine will start, run for a few seconds then stall. 3. Remove the spark plugs. 4. Install the compression tester. 5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading. 6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes. 7. Install the components in reverse order, observing the specified tightening torques. 8. Reset the PCM fault memory. Interpretation of the Results The indicated compression pressure are considered within specification if the lowest reading cylinder is within 75% of the highest reading. CAUTION: If engine oil is sprayed into the combustion chamber, after carrying out the measurement run the engine at 2000 rpm for about 15 minutes, in order to burn the oil and prevent damage to the catalytic converter. If the measurement on one or more cylinders is much lower than the specified value, spray some engine oil into the combustion chamber and repeat the compression measurement. If the reading greatly improves, the piston rings are damaged. If the reading stays the same, the cause is either damaged valve seats or valve stem seals. If the measurements for two cylinders next to each other arc both too low then it is very likely that the cylinder head gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the engine oil. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Valve Clearance > System Information > Specifications Valve Clearance: Specifications The manufacturer indicates that this vehicle has hydraulic lifters or adjusters and therefore does not require adjustment. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Specifications Mass Air Flow Sensor: Specifications Mass Air Flow (MAF) Sensor Plate Nuts 10 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Specifications > Page 3583 Mass Air Flow Sensor: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Specifications > Page 3584 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Specifications > Page 3585 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Specifications > Page 3586 Mass Air Flow Sensor: Service Precautions CAUTION: ^ Do not tamper with the sensing elements located in the Mass Air Flow (MAF) sensor.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling.

The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature.

Thermistor-type sensors are considered passive sensors.

The IAT provides air temperature information to the PCM. The PCM uses the air temperature information as a correction factor in the calculation of fuel, spark and MAF. The IAT sensor provides a quicker temperature change response time than the ECT sensor. Supercharged 5.4L Lightning vehicles use (2) IAT sensors. Both sensors operate as described above. However, one is located before the supercharger at the air cleaner for standard OBD II/cold weather input, while a second sensor (IAT2) is located after the supercharger in the intake manifold. The IAT2 sensor located after the supercharger provides air temperature information to the PCM to control border-line spark and to help determine intercooler efficiency. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor <--> [Intake Air Temperature Sensor] > Component Information > Description and Operation > Page 3599 Intake Air Temperature Sensor: Service and Repair REMOVAL 1.

A signal is then sent to the Powertrain Control Module (PCM) and used for synchronizing the firing of sequential fuel injectors. The Coil On Plug (COP) Ignition applications also use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications Coolant Temperature Sensor/Switch (For Computer): Specifications Water temperature sensor 12-17 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 3614 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General Coolant Temperature Sensor/Switch (For Computer): Description and Operation General The ECT sensor: ^ sends the PCM a signal indicating engine temperature. ^ resistance decreases as coolant temperature increases. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General > Page 3617 Coolant Temperature Sensor/Switch (For Computer): Description and Operation 2000 All (Except diesel/Propane/Villager) Engine Coolant Temperature The Engine Coolant Temperature (ECT) sensor is a thermistor device in which resistance changes with temperature.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 3641 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 3642 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 3643 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration.

If there is a communication error, attempt to communicate with a different diagnostic scan tool, such as NGS, NGS+, VCM or another WDS. NOTE IF COMMUNICATION STILL CANNOT BE ESTABLISHED, VOLTAGE DROP PCM POWERS, GROUNDS, AND CHECK VREF. PCM REPLACEMENT - STANDARD 1. Open WDS vehicle session with original PCM installed in vehicle. If the original PCM is not able to communicate, to open a session, proceed to the Blank Path Programming procedure. 2. Install the new PCM. NOTE IF WDS NEEDS TO BE USED ON A DIFFERENT VEHICLE WHILE THE NEW PCM IS BEING INSTALLED, PLACE THE VEHICLE SESSION ON "HOLD" FOR USE LATER. 3. Attempt to start the vehicle. 4. Run KOEO Self Test to check for diagnostic trouble codes (DTCs) in PCM. 5. Check for DTC P0602/P0605/P1639. a. If DTC P0602/P0605/P1639 is present then Programmable Module Installation (PMI) procedure must be performed. Use the WDS session opened at Step 1. b. If DTC P0602/P0605/P1639 is not present, then verify Programmable Parameters are properly set such as tire size, axle ratio, etc. 6. Check for DTC B2900. a. If DTC B2900 is present, perform PMI on the ABS module. Do Not replace ABS module for this procedure when directed. You may be prompted to enter the 9 lines of PCM As-Built data during this procedure. b. If DTC B2900 is not present proceed to Step 7. 7. Diagnose all other DTCs following normal diagnostic procedures. REPROGRAMMING DOES NOT COMPLETE OR FAILS - Existing PCM Reprogramming Or PCM Replacement 1. Verify all cables are properly connected. 2. Verify vehicle battery is at proper charge level. 3. Verify scan tool battery is at proper charge level. 4. Attempt reprogramming procedure again. 5. If reprogramming still does not complete properly, save current session, reboot WDS, open previous session, and attempt reprogramming again. 6. If reprogramming still does not complete or you are now unable to communicate with PCM, proceed to the Blank Path Programming procedure. BLANK PATH PROGRAMMING - Existing PCM Reprogramming Or PCM Replacement Perform this procedure prior to PCM replacement if a vehicle comes in with a PCM that will not communicate, or if steps earlier in this TSB directed you to this procedure. 1. Verify powers and grounds to PCM by loading and voltage drop testing circuits. 2. Follow Pin Point Tests to verify network integrity.

Use WDS if available. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Technical Service Bulletins > All Other Service Bulletins for Powertrain Control Module: > 04-24-14 > Dec > 04 > Engine Controls - General PCM Programming Procedures > Page 3681 a. Make sure WDS is docked or attached to vehicle battery supply. b. Verify WDS software is at the latest release level. 3. If there is a communication error, attempt to communicate with a different diagnostic scan tool, such as NGS, NGS+, VCM or another WDS. NOTE IF COMMUNICATION STILL CANNOT BE ESTABLISHED, VOLTAGE DROP PCM POWERS, GROUNDS, AND CHECK VREF. PCM REPLACEMENT - STANDARD 1. Open WDS vehicle session with original PCM installed in vehicle. If the original PCM is not able to communicate, to open a session, proceed to the Blank Path Programming procedure. 2. Install the new PCM. NOTE IF WDS NEEDS TO BE USED ON A DIFFERENT VEHICLE WHILE THE NEW PCM IS BEING INSTALLED, PLACE THE VEHICLE SESSION ON "HOLD" FOR USE LATER. 3. Attempt to start the vehicle. 4. Run KOEO Self Test to check for diagnostic trouble codes (DTCs) in PCM. 5. Check for DTC P0602/P0605/P1639. a. If DTC P0602/P0605/P1639 is present then Programmable Module Installation (PMI) procedure must be performed. Use the WDS session opened at Step 1. b. If DTC P0602/P0605/P1639 is not present, then verify Programmable Parameters are properly set such as tire size, axle ratio, etc. 6. Check for DTC B2900. a. If DTC B2900 is present, perform PMI on the ABS module. Do Not replace ABS module for this procedure when directed. You may be prompted to enter the 9 lines of PCM As-Built data during this procedure. b. If DTC B2900 is not present proceed to Step 7. 7. Diagnose all other DTCs following normal diagnostic procedures. REPROGRAMMING DOES NOT COMPLETE OR FAILS - Existing PCM Reprogramming Or PCM Replacement 1. Verify all cables are properly connected. 2. Verify vehicle battery is at proper charge level. 3. Verify scan tool battery is at proper charge level. 4. Attempt reprogramming procedure again. 5. If reprogramming still does not complete properly, save current session, reboot WDS, open previous session, and attempt reprogramming again. 6. If reprogramming still does not complete or you are now unable to communicate with PCM, proceed to the Blank Path Programming procedure. BLANK PATH PROGRAMMING - Existing PCM Reprogramming Or PCM Replacement Perform this procedure prior to PCM replacement if a vehicle comes in with a PCM that will not communicate, or if steps earlier in this TSB directed you to this procedure. 1.

The EEPROM contains the vehicle strategy including calibration information specific to the vehicle. The IC has the capability to be reprogrammed or reflashed. This is described below by the Flash EEPROM Procedure. As part of the calibration there is an area referred to as the Vehicle Identification (VID) Block. The VID block must be programmed when replacing the PCM and is described under Programming the VID Block for a Replacement PCM. The VID block is an existing PCM can also be tailored to accommodate various hardware changes made to the vehicle since production. This is described under Making Changes to the VID Block and also under the FLASH EEPROM Procedure. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VID number, octane adjust, fuel octane. fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control, four wheel drive and manual versus non manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool. When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to reflash the PCM to reset the VID block. This is accomplished by the Flash EEPROM Procedure. Programming the VID Block for a Replacement PCM A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and in need of programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM. Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of the scan tool to retrieve data from the old PCM before removing from the vehicle. The stored data can now be downloaded to the new PCM after replacing. This same process can also be accomplished during the Flash EEPROM Procedure described below. Manual data entry must be performed if the old module is damaged and not capable of communicating. Remove and replace the old PCM. Contact the "AS BUILT" data center by fax for the data needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used. The following information will need to be faxed in: dealer name, dealer P & A code, dealer phone number, dealer fax number, technician's name, VIN and module being programmed. The necessary VID block data will then be faxed back. Enter the vehicle data string provided by the "AS BUILT" data center. Refer to the Worldwide Diagnostic System users manual for details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Temperature Sensor > Component Information > Specifications Engine Temperature Sensor: Specifications Cylinder head temperature sensor (CHT) 18 - 20 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Temperature Sensor > Component Information > Specifications > Page 3698 Engine Temperature Sensor: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Temperature Sensor > Component Information > Specifications > Page 3699 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Temperature Sensor > Component Information > Specifications > Page 3700 Engine Temperature Sensor: Description and Operation The CHT sensor: ^ is mounted into the wall of the cylinder head and is not connected to any coolant passages. ^ sends a signal to the PCM indicating cylinder head temperature. If the temperature exceeds 130°C (265°F), the PCM disables four fuel injectors at a time. The PCM will alternate which four fuel injectors are disabled every 32 engine cycles. The four cylinders the are not being fuel injected act as air pumps to aid in cooling the engine. - If the temperature exceeds 166°C (330°F), the PCM disables all of the fuel injectors until the engine temperature drops below 153°C (308°F). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Temperature Sensor > Component Information > Specifications > Page 3701 Engine Temperature Sensor: Service and Repair Removal and Installation Warning: The electrical power to the air suspension system must be shut off prior to hoisting or jacking an air suspension vehicle. This can be accomplished by turning off the air suspension switch located below the glove box in the lower right of the passenger foot well. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during the operations. Failed to follow the instruction may result in personal injury. 1. Raise the vehicle on a hoist. 2. Remove the right front fender splash shield. 3. Remove the dual converter Y-pipe. 4.

The electrical resistance of a strain gauge increases as pressure increases, and decreases as pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to pressure. Strain gauge type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. The Fuel Rail Pressure (FRP) sensor senses the pressure difference between the fuel rail and the intake manifold. The return fuel line to the fuel tank has been deleted in this type of fuel system. The differential fuel/intake manifold pressure together with measured fuel temperature provides an indication of the fuel vapors in the fuel rail. Both differential pressure and temperature feedback signals are used to control the speed of the fuel pump. The speed of the fuel pump sustains fuel rail pressure which preserve fuel in its liquid state. The dynamic range of the fuel injectors increase because of the higher rail pressure, which allows the injector pulse width to decrease. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations > Page 3708 Fuel Tank Pressure Sensor: Service Precautions CAUTION: The fuel tank pressure sensor must be disengaged from the fuel tank before it can be removed.

The IAC valve assembly meters intake air around the throttle plate through a bypass within the IAC valve assembly and throttle body. The PCM determines the desired idle speed or bypass air and signals the IAC valve assembly through a specified duty cycle. The IAC valve responds by positioning the IAC valve to control the amount of bypassed air. The PCM monitors engine rpm and increases or decreases the AC duty cycle in order to achieve the desired rpm. On applications with air-assisted injectors, the IAC valve also supplies a small amount of air into the path of the fuel injectors.

NOTE: The IAC Valve Assembly is NOT ADJUSTABLE and CANNOT BE CLEANED. The IAC valve (part of throttle body assembly) has an internal diode on some applications. If the internal diode is measured in crossed terminal position with a digital multimeter, there will be an incorrect or negative reading. It is important that the mating component and harness connectors are correctly oriented. Diagnostic procedures emphasize this importance. The PCM uses the IAC valve assembly to control: ^ No touch start ^ Cold engine fast idle for rapid warm-up ^ Idle (corrects for engine load) ^ Stumble or stalling on deceleration (provides a dashpot function) ^ Over-temperature idle boost. ^ Air Assist to Injectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Air Control Valve <--> [Idle Speed/Throttle Actuator - Electronic] > Component Information > Description and Operation > Page 3721 Idle Air Control Valve: Testing and Inspection Idle Air Control (IAC) Valve Check 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage.

CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3737 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3738 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3739 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3740 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3741 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3742 Multiplex Communication Network: Electrical Diagrams Diagram 14-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Diagrams > Diagram Information and Instructions > Page 3743 Diagram 14-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Description and Operation > Description and Operation Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Description and Operation > Description and Operation > Page 3746 Multiplex Communication Network: Description and Operation Principles and Operation The vehicle has two module communication networks. The Standard Corporate Protocol (SCP), which is an unshielded twisted-pair cable (data bus plus, circuit 914 and data bus minus, circuit 915 ) and the International Standards Organization (ISO) 9141 communications network, which is a single-wire network (circuit 70 [/WH]). Both networks can be connected to the scan tool through one connector called the Data Link Connector (DLC). The DLC can be found under the instrument panel between the steering column and the radio. The SCP communication network allows inter-module communication. This allows single inputs or outputs to be shared by multiple modules over common circuits. The SCP network will remain operational even with the severing of one of the bus wires. Communications will also continue if one of the bus wires is shorted to ground or power, or if some, but not all, termination resistors are lost. The PCM is the only module that contains termination resistors. The ISO 9141 communications network does not permit inter-module communication. When the scan tool communicates to modules on the ISO 9141 communication network, the scan tool initiates all communications. Unlike the SCP network, the ISO 9141 communication network will not function if the network is shorted to ground or power. Also, if one of the modules on the ISO 9141 communication network loses power or shorts internally, communications to that module will fail. The PCM is on the SCP communication network. The PCM controls the engine for better fuel economy, emissions control and failure mode detection and storage. This module also performs all Passive Anti-theft System (PATS) functions. For additional PCM information, refer to Powertrain Management. For PATS information, refer to Antitheft and Alarm Systems. The Restraint Control Module (RCM) is on the ISO 9141 communication network. The RCM controls the deployment of the air bags based on sensor input. For additional information, refer to Air Bag Systems. The Electronic Automatic Temperature Control (EATC) module is on the SCP communication network. The EATC module controls automatic climate functions that maintain the vehicle interior temperature at a constant setting. For additional information, refer to Heating and Air Conditioning. The Generic Electronic Module (GEM) is on the ISO 9141 communication network. The GEM controls a variety of systems: ^ windshield wipers ^ courtesy lamps ^ 4-wheel shift on the fly ^ warning chimes ^ one-touch down power windows For additional GEM information, refer to Multifunction Electronic Control Module. The Driver Seat Module (DSM) is on the ISO 9141 communication network. The DSM controls the positioning and programming of the driver seat, pedals and both outside mirrors. For additional information, refer to Seats. The Remote Anti-theft Personality (RAP) module is on the ISO 9141 communication network. The RAP module controls the remote entry, interior lamp illumination signal to the GEM and panic alarm from the keyless entry remote. For additional information, refer to Keyless Entry. The anti-lock brake control module is on the ISO 9141 communication network. The module controls brake pressure to the four wheels to keep the vehicle under control while braking. For additional information, refer to Antilock Brake System. The following describes the rear- and four-wheel air suspension modules: The air suspension control module is on the ISO 9141 communication network and controls the air compressor motor (through a solid state relay) and all system solenoids. The module also provides power to front and rear height sensors on four-wheel air suspension systems, or rear height sensors on the rear-wheel suspension systems. The module controls vehicle height adjustments by monitoring two height sensors, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals and the brake switch. The module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing the vehicle and module. The control module is mounted in the passenger compartment inside the instrument panel above the radio and temperature controls. The air suspension control module monitors and controls the system through a 32-pin two-way connector. It is keyed so that the control module cannot be plugged into an incorrect harness. There are two sides of the harness connection to the module. Each is uniquely colored and keyed to prevent reversal of connections. For additional information on the rear-wheel air suspension, refer to Electronic Level Control. For additional information on the four-wheel air suspension, refer to Electronic Level Control. The instrument cluster is on the SCP communication network. The instrument cluster is also called a Hybrid Electronic Cluster (HEC). It is an analog Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Description and Operation > Description and Operation > Page 3747 face cluster with a digital odometer. The instrument cluster displays a variety of information. For additional information, refer to Instrument Panel, Gauges and Warning Indicators. The Parking Aid Module (PAM) is connected to the ISO 9141 communication module. The module controls sensors in the rear bumper that detect close objects when the vehicle is in reverse. For additional information, refer to Collision Avoidance and Parking Assist Systems. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Multiplex Communication Network <--> [Information Bus] > Component Information > Description and Operation > Description and Operation > Page 3748 Multiplex Communication Network: Description and Operation Principles of Operation Some modules support the ability to change specified factory configuration settings and preset preference items. The process used to change the settings and customer preference items is module configuration. This vehicle supports two methods of module configuration. ^ Customer preference items ^ Anti-theft configure Customer Preference Items This method is used to enable or disable module-controlled items or systems to suit the preference of the customer. Not all features controlled by the module are listed in this configuration method. Refer to the Module Configuration Index for a list of features per module.

The electrical resistance of a thermistor decreases as the temperature increases and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature. Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. Engine Coolant Temperature (ECT) Sensor The EOT measures the temperature of the engine oil. The EOT sensor is similar in construction to the Engine Coolant Temperature (ECT) sensor. On some applications, EOT input to the PCM is used to initiate a soft engine shutdown. This prevents engine damage from occurring as a result of high oil temperature. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis Technical Service Bulletin # 01-9-7 Date: 010514 Emissions/Engine Controls - Driveability Diagnosis Article No. 01-9-7 05/14/01 DRIVEABILITY - H025 (HEATED OXYGEN SENSOR), CATALYST, AND FUEL SYSTEM MONITORS - SERVICE TIPS - OBD II VEHICLES ONLY FORD: 1994-1997 THUNDERBIRD 1994-2001 MUSTANG 1995-2001 CROWN VICTORIA 1996-1997 PROBE 1996-2000 CONTOUR 1996-2001 ESCORT, TAURUS 2000-2001 FOCUS 1994-1997 F SUPER DUTY, F-250 HD, F-350 1995-2001 ECONOLINE, RANGER, WINDSTAR 1996 BRONCO 1996-1997 AEROSTAR 1996-2001 EXPLORER 1997-2001 EXPEDITION, F-150, F-250 LD 1999-2001 SUPER DUTY F SERIES 2000-2001 EXCURSION 2001 ESCAPE LINCOLN: 1995-2001 CONTINENTAL, TOWN CAR 1996-1998 MARK VIII 2000-2001 LS 1998-2001 NAVIGATOR MERCURY: 1994-1997 COUGAR 1995-2001 GRAND MARQUIS 1996-1999 TRACER 1996-2000 MYSTIQUE 1996-2001 SABLE 1999-2001 COUGAR 1997-2001 MOUNTAINEER ISSUE This article is intended to be an aide in diagnosing conditions related to Heated Oxygen Sensor (HO2S), Catalyst, and Fuel System Monitor related Diagnostic Trouble Codes (DTCs).

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3834 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3835 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3836 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3837 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3838 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3839 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3840 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3841 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3842 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3843 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3844 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3845 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 3846 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 3847 Heated Oxygen Sensor: Specifications Heated Oxygen Sensor 46 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 3848 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions Heated Oxygen Sensor: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3851 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3859 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3860 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3861 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3862 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3863 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3864 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 3865 Heated Oxygen Sensor: Connector Views Ford does not give the connector view. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Page 3866 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General Heated Oxygen Sensor: Description and Operation General The HO2S: ^ has the ability to create a voltage signal dependent on exhaust oxygen content. ^ provides feedback information to the PCM used to calculate fuel delivery. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General > Page 3869 Heated Oxygen Sensor: Description and Operation Heated Oxygen Sensor Heated Oxygen Sensor The Heated Oxygen Sensor (HO2S) detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. A high concentration of oxygen (lean air/fuel ratio) in the exhaust produces a low voltage signal less than 0.4 volt. A low concentration of oxygen (rich air/fuel ratio) produces a high voltage signal greater than 0.6 volt. The HO2S provides feedback to the PCM indicating air/fuel ratio in order to achieve a near stoichiometric air/fuel ratio of 14.7:1 during closed loop engine operation. The HO2S generates a voltage between 0.0 and 1.1 volts. Heated Oxygen Sensor (HO2S) Embedded with the sensing element is the HO2S heater. The heating element heats the sensor to temperatures of 800°C (1400°F). At approximately 300°C (600°F) the engine can enter closed loop operation. The VPWR circuit supplies voltage to the heater and the PCM will complete the ground when the proper conditions occur. For model year 1998 a new HO2S heater and heater control system are installed on some vehicles. The high power heater reaches closed loop fuel control temperatures. The use of this heater requires that the HO2S heater control be duty cycled, to prevent damage to the heater. The 6 ohm design is not interchangeable with new style 3.3 ohm heater. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > Page 3870 Heated Oxygen Sensor: Service and Repair EGO Sensor Wrench SPECIAL SERVICE TOOL(S) REMOVAL 1.

The differential pressure feedback sensor receives this signal through two hoses referred to as the downstream pressure hose (REF SIGNAL) and upstream pressure hose (HI SIGNAL). The HI and REF hose connections are marked on the aluminum differential pressure feedback EGR sensor housing for identification (note that the HI signal uses a larger diameter hose). The differential pressure feedback EGR sensor outputs a voltage proportional to the pressure drop across the metering orifice and supplies it to the PCM as EGR flow rate feedback. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Pressure Feedback Exhaust Sensor, EGR > Component Information > Description and Operation > Differential Pressure Feedback EGR Sensor > Page 3880 Pressure Feedback Exhaust Sensor: Description and Operation General The differential pressure feedback EGR sensor: ^ monitors the EGR flow rate through the EGR valve tube. ^ sends an EGR flow rate signal to the Powertrain Control Module (PCM). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Pressure Feedback Exhaust Sensor, EGR > Component Information > Description and Operation > Page 3881 Pressure Feedback Exhaust Sensor: Service and Repair REMOVAL 1.

Make sure WDS is docked or attached to vehicle battery supply. b. Verify WDS software is at the latest release level. 3. If there is a communication error, attempt to communicate with a different diagnostic scan tool, such as NGS, NGS+, VCM or another WDS. NOTE IF COMMUNICATION STILL CANNOT BE ESTABLISHED, VOLTAGE DROP PCM POWERS, GROUNDS, AND CHECK VREF. PCM REPLACEMENT - STANDARD 1. Open WDS vehicle session with original PCM installed in vehicle. If the original PCM is not able to communicate, to open a session, proceed to the Blank Path Programming procedure. 2. Install the new PCM. NOTE IF WDS NEEDS TO BE USED ON A DIFFERENT VEHICLE WHILE THE NEW PCM IS BEING INSTALLED, PLACE THE VEHICLE SESSION ON "HOLD" FOR USE LATER. 3. Attempt to start the vehicle. 4. Run KOEO Self Test to check for diagnostic trouble codes (DTCs) in PCM. 5. Check for DTC P0602/P0605/P1639. a. If DTC P0602/P0605/P1639 is present then Programmable Module Installation (PMI) procedure must be performed. Use the WDS session opened at Step 1. b. If DTC P0602/P0605/P1639 is not present, then verify Programmable Parameters are properly set such as tire size, axle ratio, etc. 6. Check for DTC B2900. a. If DTC B2900 is present, perform PMI on the ABS module. Do Not replace ABS module for this procedure when directed. You may be prompted to enter the 9 lines of PCM As-Built data during this procedure. b. If DTC B2900 is not present proceed to Step 7. 7. Diagnose all other DTCs following normal diagnostic procedures. REPROGRAMMING DOES NOT COMPLETE OR FAILS - Existing PCM Reprogramming Or PCM Replacement 1. Verify all cables are properly connected. 2. Verify vehicle battery is at proper charge level. 3. Verify scan tool battery is at proper charge level. 4. Attempt reprogramming procedure again. 5. If reprogramming still does not complete properly, save current session, reboot WDS, open previous session, and attempt reprogramming again. 6. If reprogramming still does not complete or you are now unable to communicate with PCM, proceed to the Blank Path Programming procedure. BLANK PATH PROGRAMMING - Existing PCM Reprogramming Or PCM Replacement Perform this procedure prior to PCM replacement if a vehicle comes in with a PCM that will not communicate, or if steps earlier in this TSB directed you to this procedure. 1. Verify powers and grounds to PCM by loading and voltage drop testing circuits. 2. Follow Pin Point Tests to verify network integrity.

The EEPROM contains the vehicle strategy including calibration information specific to the vehicle. The IC has the capability to be reprogrammed or reflashed. This is described below by the Flash EEPROM Procedure. As part of the calibration there is an area referred to as the Vehicle Identification (VID) Block. The VID block must be programmed when replacing the PCM and is described under Programming the VID Block for a Replacement PCM. The VID block is an existing PCM can also be tailored to accommodate various hardware changes made to the vehicle since production. This is described under Making Changes to the VID Block and also under the FLASH EEPROM Procedure. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VID number, octane adjust, fuel octane. fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control, four wheel drive and manual versus non manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool. When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to reflash the PCM to reset the VID block. This is accomplished by the Flash EEPROM Procedure. Programming the VID Block for a Replacement PCM A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and in need of programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM. Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of the scan tool to retrieve data from the old PCM before removing from the vehicle. The stored data can now be downloaded to the new PCM after replacing. This same process can also be accomplished during the Flash EEPROM Procedure described below. Manual data entry must be performed if the old module is damaged and not capable of communicating. Remove and replace the old PCM. Contact the "AS BUILT" data center by fax for the data needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used. The following information will need to be faxed in: dealer name, dealer P & A code, dealer phone number, dealer fax number, technician's name, VIN and module being programmed. The necessary VID block data will then be faxed back. Enter the vehicle data string provided by the "AS BUILT" data center.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications Coolant Temperature Sensor/Switch (For Computer): Specifications Water temperature sensor 12-17 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 3959 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General Coolant Temperature Sensor/Switch (For Computer): Description and Operation General The ECT sensor: ^ sends the PCM a signal indicating engine temperature. ^ resistance decreases as coolant temperature increases. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Description and Operation > General > Page 3962 Coolant Temperature Sensor/Switch (For Computer): Description and Operation 2000 All (Except diesel/Propane/Villager) Engine Coolant Temperature The Engine Coolant Temperature (ECT) sensor is a thermistor device in which resistance changes with temperature.

The electrical resistance of a strain gauge increases as pressure increases, and decreases as pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to pressure. Strain gauge type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. The Fuel Rail Pressure (FRP) sensor senses the pressure difference between the fuel rail and the intake manifold. The return fuel line to the fuel tank has been deleted in this type of fuel system. The differential fuel/intake manifold pressure together with measured fuel temperature provides an indication of the fuel vapors in the fuel rail. Both differential pressure and temperature feedback signals are used to control the speed of the fuel pump. The speed of the fuel pump sustains fuel rail pressure which preserve fuel in its liquid state. The dynamic range of the fuel injectors increase because of the higher rail pressure, which allows the injector pulse width to decrease. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Fuel Tank Pressure Sensor > Component Information > Locations > Page 3986 Fuel Tank Pressure Sensor: Service Precautions CAUTION: The fuel tank pressure sensor must be disengaged from the fuel tank before it can be removed.

This prevents engine damage from occurring as a result of high oil temperature. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis Technical Service Bulletin # 01-9-7 Date: 010514 Emissions/Engine Controls - Driveability Diagnosis Article No. 01-9-7 05/14/01 DRIVEABILITY - H025 (HEATED OXYGEN SENSOR), CATALYST, AND FUEL SYSTEM MONITORS - SERVICE TIPS - OBD II VEHICLES ONLY FORD: 1994-1997 THUNDERBIRD 1994-2001 MUSTANG 1995-2001 CROWN VICTORIA 1996-1997 PROBE 1996-2000 CONTOUR 1996-2001 ESCORT, TAURUS 2000-2001 FOCUS 1994-1997 F SUPER DUTY, F-250 HD, F-350 1995-2001 ECONOLINE, RANGER, WINDSTAR 1996 BRONCO 1996-1997 AEROSTAR 1996-2001 EXPLORER 1997-2001 EXPEDITION, F-150, F-250 LD 1999-2001 SUPER DUTY F SERIES 2000-2001 EXCURSION 2001 ESCAPE LINCOLN: 1995-2001 CONTINENTAL, TOWN CAR 1996-1998 MARK VIII 2000-2001 LS 1998-2001 NAVIGATOR MERCURY: 1994-1997 COUGAR 1995-2001 GRAND MARQUIS 1996-1999 TRACER 1996-2000 MYSTIQUE 1996-2001 SABLE 1999-2001 COUGAR 1997-2001 MOUNTAINEER ISSUE This article is intended to be an aide in diagnosing conditions related to Heated Oxygen Sensor (HO2S), Catalyst, and Fuel System Monitor related Diagnostic Trouble Codes (DTCs).

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4019 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4020 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4021 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4022 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4023 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4024 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4025 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4026 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4027 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4028 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4029 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4030 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4031 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 4032 Heated Oxygen Sensor: Specifications Heated Oxygen Sensor 46 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Technical Service Bulletins > Page 4033 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions Heated Oxygen Sensor: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4036 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4044 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4045 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4046 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4047 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4048 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4049 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Diagram Information and Instructions > Page 4050 Heated Oxygen Sensor: Connector Views Ford does not give the connector view. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Diagrams > Page 4051 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General Heated Oxygen Sensor: Description and Operation General The HO2S: ^ has the ability to create a voltage signal dependent on exhaust oxygen content. ^ provides feedback information to the PCM used to calculate fuel delivery. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > General > Page 4054 Heated Oxygen Sensor: Description and Operation Heated Oxygen Sensor Heated Oxygen Sensor The Heated Oxygen Sensor (HO2S) detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. A high concentration of oxygen (lean air/fuel ratio) in the exhaust produces a low voltage signal less than 0.4 volt. A low concentration of oxygen (rich air/fuel ratio) produces a high voltage signal greater than 0.6 volt. The HO2S provides feedback to the PCM indicating air/fuel ratio in order to achieve a near stoichiometric air/fuel ratio of 14.7:1 during closed loop engine operation. The HO2S generates a voltage between 0.0 and 1.1 volts. Heated Oxygen Sensor (HO2S) Embedded with the sensing element is the HO2S heater. The heating element heats the sensor to temperatures of 800°C (1400°F). At approximately 300°C (600°F) the engine can enter closed loop operation. The VPWR circuit supplies voltage to the heater and the PCM will complete the ground when the proper conditions occur. For model year 1998 a new HO2S heater and heater control system are installed on some vehicles. The high power heater reaches closed loop fuel control temperatures. The use of this heater requires that the HO2S heater control be duty cycled, to prevent damage to the heater. The 6 ohm design is not interchangeable with new style 3.3 ohm heater. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Heated Oxygen Sensor <--> [Oxygen Sensor] > Component Information > Description and Operation > Page 4055 Heated Oxygen Sensor: Service and Repair EGO Sensor Wrench SPECIAL SERVICE TOOL(S) REMOVAL 1.

The differential pressure feedback sensor receives this signal through two hoses referred to as the downstream pressure hose (REF SIGNAL) and upstream pressure hose (HI SIGNAL). The HI and REF hose connections are marked on the aluminum differential pressure feedback EGR sensor housing for identification (note that the HI signal uses a larger diameter hose). The differential pressure feedback EGR sensor outputs a voltage proportional to the pressure drop across the metering orifice and supplies it to the PCM as EGR flow rate feedback. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Pressure Feedback Exhaust Sensor, EGR > Component Information > Description and Operation > Differential Pressure Feedback EGR Sensor > Page 4065 Pressure Feedback Exhaust Sensor: Description and Operation General The differential pressure feedback EGR sensor: ^ monitors the EGR flow rate through the EGR valve tube. ^ sends an EGR flow rate signal to the Powertrain Control Module (PCM). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Pressure Feedback Exhaust Sensor, EGR > Component Information > Description and Operation > Page 4066 Pressure Feedback Exhaust Sensor: Service and Repair REMOVAL 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less.

If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission transaxle shift scheduling and torque converter clutch scheduling. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis Technical Service Bulletin # 01-9-7 Date: 010514 Emissions/Engine Controls - Driveability Diagnosis Article No. 01-9-7 05/14/01 DRIVEABILITY - H025 (HEATED OXYGEN SENSOR), CATALYST, AND FUEL SYSTEM MONITORS - SERVICE TIPS - OBD II VEHICLES ONLY FORD: 1994-1997 THUNDERBIRD 1994-2001 MUSTANG 1995-2001 CROWN VICTORIA 1996-1997 PROBE 1996-2000 CONTOUR 1996-2001 ESCORT, TAURUS 2000-2001 FOCUS 1994-1997 F SUPER DUTY, F-250 HD, F-350 1995-2001 ECONOLINE, RANGER, WINDSTAR 1996 BRONCO 1996-1997 AEROSTAR 1996-2001 EXPLORER 1997-2001 EXPEDITION, F-150, F-250 LD 1999-2001 SUPER DUTY F SERIES 2000-2001 EXCURSION 2001 ESCAPE LINCOLN: 1995-2001 CONTINENTAL, TOWN CAR 1996-1998 MARK VIII 2000-2001 LS 1998-2001 NAVIGATOR MERCURY: 1994-1997 COUGAR 1995-2001 GRAND MARQUIS 1996-1999 TRACER 1996-2000 MYSTIQUE 1996-2001 SABLE 1999-2001 COUGAR 1997-2001 MOUNTAINEER ISSUE This article is intended to be an aide in diagnosing conditions related to Heated Oxygen Sensor (HO2S), Catalyst, and Fuel System Monitor related Diagnostic Trouble Codes (DTCs).

Heated Oxygen Sensor (HO2S) Monitor - Information Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4122 The H025 Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors (Figures 1 and 3) are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors (Figures 1 and 3) used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the ECT or CHT, IAT, MAF, TP and CKP sensors to activate the H025 Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt. Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. ^ The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. ^ Once the HO2S Monitor is enabled, the upstream H025 signal voltage amplitude and response frequency are checked. Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. ^ A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed. A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate. ^ An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by measuring the current going through the heater circuit. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The HO2S Monitor DTCs can be categorized as follows: ^ HO2S signal circuit malfunction - P0131, P0136, P0151, P0156 ^ HO2S slow response rate - P0133, P0153 ^ HO2S heater circuit malfunction - P0135, P0141, P0155, P0161 ^ Downstream HO2S not running in on-demand self test - P1127 ^ Swapped H025 connectors - P1128 and P1129 ^ H025 lack of switching - P1130, P1131, P1132, P1150, P1151, P1152 ^ HO2S lack of switching (sensor indicates lean) - P1137 ^ H025 lack of switching (sensor indicates rich) - P1138 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4123 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4124 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4125 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4126 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4127 C2.) Heated Oxygen Sensor (HO2S) Monitor - Diagnostic Trouble Codes D. Catalyst Efficiency Monitor D1.) Catalyst Efficiency Monitor - Information The Federal Test Procedure Catalyst Monitor monitors for deterioration in the catalyst system and illuminates the MIL when tailpipe emissions exceed the appropriate HC emission thresholds. The Catalyst Monitor is enabled after the upstream and downstream HO2S sensors have been tested and verified to be functional. This monitor relies on the front and rear heated oxygen sensors (HO2S) to infer catalyst efficiency based upon oxygen storage capacity. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the rear HO2S quite slow compared with the frequency of the front HO2S. As catalyst efficiency deteriorates, its ability to store oxygen declines, and the rear HO2S begins to switch more rapidly, approaching the frequency of the front sensor. In general, as catalyst efficiency decreases, the switch ratio increases from a switch ratio of 0 for a low mileage catalyst to a switch ratio of 0.8 or 0.9 for a low efficiency catalyst. Some vehicles will monitor substantially less than the entire catalyst volume in order to meet the stringent catalyst monitoring malfunction thresholds. In many cases, only the front, light-off catalyst is monitored. Front and rear HO2S switches are counted under specified closed loop fuel conditions. After the required number of front switches are obtained, a rear-to-front HO2S switch ratio is calculated. The switch ratio is compared against a threshold value. If the switch ratio is greater than the calibrated maximum limit, the catalyst has failed. The test entry conditions for the Catalyst Efficiency Monitor are as follows: ECT or CHT (warmed engine), IAT (not at extreme ambient temperatures), MAF (greater than minimum engine load), VSS (within vehicle speed window) and TP (at part throttle) are required. ^ Because an exponentially weighted moving average is used for malfunction determination, up to six OBD II drive cycles may be required to illuminate the MIL. NOTE THE CATALYST MONITOR ON SOME EARLY OBD II VEHICLES (SOME 1994-1996 VEHICLES) WAS REFERRED TO AS THE "STEADY-STATE CATALYST MONITOR" AS OPPOSED TO THE "FTP CATALYST MONITOR" (DESCRIBED ABOVE) THAT IS MOST COMMON FOR VEHICLES BUILT AFTER 1996. BELOW IS A BRIEF DESCRIPTION OF THE STEADY-STATE CATALYST MONITOR: The Steady-State Catalyst Monitor performs a 20 second test during steady state rpm and load conditions. The Monitor transfers closed loop fuel control from the front to the rear 02 sensors. The Monitor then observes the switching frequency and compares it to a threshold frequency stored in an rpm/load table. A frequency higher than the maximum calibrated threshold indicates a malfunction. The Catalyst Monitor DTCs can be categorized as follows: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4128 ^ Catalyst system efficiency below threshold (Bank 1) - P0420 ^ Catalyst system efficiency below threshold (Bank 2) - P0430 D2.) Catalyst Efficiency Monitor - Diagnostic Trouble Codes E. Fuel System Monitor E1.) Fuel System Monitor - Information The Fuel System Monitor is an on-board strategy designed to monitor the fuel trim system. The fuel control system uses fuel trim tables stored in the PCM's KAM to compensate for variability in fuel system components due to normal wear and aging. Fuel trim tables are based on vehicle speed and engine load. During closed loop vehicle operation, the fuel trim strategy learns the corrections needed to correct a "biased" rich or lean fuel system. The correction is stored in the fuel trim tables. The fuel trim has two means of adapting; a LONGFT and a SHRTFT. LONGFT relies on the fuel trim tables and SHRTFT refers to the desired air/fuel ratio parameter "LAMBSE". LAMBSE is calculated by the PCM from HO2S inputs and helps maintain a 14.7:1 air/fuel ratio during closed loop operation. SHRTFT and LONGFT work together. If the HO2S indicates the engine is running rich, the PCM will correct the rich condition by moving SHRTFT in the negative range (less fuel to correct for a rich combustion). If after a certain amount of time SHRTFT is still compensating for a rich condition, the PCM "learns" this and moves LONGFT into the negative range to compensate and allows SHRTFT to return to a value near 0%. Input from the ECT or CHT, IAT, and MAF sensors is required to activate the fuel trim system, which in turn activates the Fuel System Monitor. Once activated, the Fuel System Monitor looks for the fuel trim tables to reach the adaptive clip (adaptive limit) and LAMBSE to exceed a calibrated limit. The Fuel System Monitor will store the appropriate DTC when a fault is detected as described below. ^ The H025 detects the presence of oxygen in the exhaust and provides the PCM with feedback indicating a rich or lean condition. ^ A correction factor is added to the fuel injector pulsewidth calculation according to the Long and Short Term Fuel Trims as needed to compensate for variations in the fuel system. ^ When deviation in the parameter LAMBSE increases, air/fuel control suffers and emissions increase. When LAMBSE exceeds a calibrated limit and the fuel trim table has clipped (reached adaptive limit), the Fuel System Monitor sets a DTC. ^ The MIL is activated after a fault is detected on two consecutive OBD II drive cycles. The Fuel System Monitor DTCs can be categorized as follows: ^ Fuel Delivery Error - P0148 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4129 ^ Lean shift in fuel system operation - P0171 (Bank 1) and P0174 (Bank 2) ^ Rich shift in fuel system operation - P0172 (Bank 1) and P0175 (Bank 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4130 E2.) Fuel System Monitor - Diagnostic Trouble Codes F. Diagnostic Service Tips 1. Always reset KAM after performing a repair: After performing a repair on a vehicle with the MIL on, and/or DTCs present, always clear KAM. When a malfunction is present, the PCM adapts (attempts to correct) for this condition. Once the vehicle has been repaired, if the KAM is not reset, the PCM will once again have to adapt back to the normal operating conditions. Clearing the KAM will erase what the PCM has learned, so the PCM will be able to start with "base tables". 2. Always view and record Freeze Frame Data: Freeze Frame Data can be a valuable asset in duplicating and diagnosing concerns. This data (a snapshot of certain PID values, recorded at the time the MIL was activated) indicates the manner in which the vehicle was being driven at the time the fault occurred. This can be especially useful on intermittent concerns. Freeze Frame Data, in some cases, can also help to isolate possible areas of concern, as well as ruling out others. Always record (write down) the Freeze Frame Data. 3. Multiple DTCs (with the same meaning): When multiple (paired) DTCs with the same meaning are set for multiple sensors, it is unlikely that replacing both HO2S sensors will resolve the concern. In most cases, there will be another issue that is causing the codes. Examples of multiple (paired) DTCs: (P0135/P0155), (P0141/P0161), (P1131/P1151), (P1132/P1152). To further clarify this, see the more detailed scenario as follows: A vehicle comes in with a MIL On concern. KOEO self test reveals DTCs P0135 and P0155 (HTR-11 and HTR-21 circuit malfunction), with no other DTCs present. The most likely cause of these DTCs would be something in the heater power circuit that both of these HO2S sensors have in common (Example: open or shorted heater circuit wiring or splice). It is highly unlikely that multiple sensors would fail at the same time. When multiple DTCs of this nature are encountered, reviewing the appropriate wiring diagram(s) can help to isolate possible areas of concern. When reviewing the wiring diagram, look for things that the affected sensors have in common. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4131 In this example, the most likely cause of DTCs P0135 and P0155 (with no other DTCs present) would be a concern with Splice "B" (refer to Figure 2). NOTE THIS ILLUSTRATION IS ONLY AN EXAMPLE. SPLICE NAMES "A", "B", AND "C" ARE USED IN THIS EXAMPLE FOR CONVENIENCE ONLY. ON AN ACTUAL VEHICLE, SPLICE NAMES WILL DEPEND ON THE CIRCUIT NUMBER FOR THE VEHICLE UNDER REPAIR. NOTE ALSO THAT THIS FIGURE IS NOT INTENDED TO SHOW ALL SPLICES/CONNECTIONS ON ALL VEHICLES. OTHER EEC CIRCUITS, NOT SHOWN, MAY ALSO BE SPLICED IN WITH THE CIRCUITS SHOWN. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4132 4. View H025 PID data carefully: NGS PIDs for HO2S sensors that do not exist (with certain exhaust configurations) will show a value of "0" volts (refer to Figures 3 and 4). In this example, the vehicle (equipped with a 4-cylinder engine) has one upstream and one downstream HO2S. Notice that the NGS (scan tool) display shows two upstream and two downstream HO2S PIDs, and that the "unused" HO2S sensor PIDs display "0" volts. 5. H025 sensors measure oxygen in the exhaust, not fuel: The exhaust gas condition reported by the HO2S sensor is based on the presence of oxygen in the exhaust, not the presence of unburned fuel. Example: In the event of an ignition-related misfire, you might expect a rich HO2S reading, due to the amount of unburned fuel in the exhaust system. However, there is also a large amount of unburned oxygen, since no combustion took place in the misfiring cylinder. Since the H025 senses oxygen only, it would report a lean condition in this particular situation. F2.) Tips Related to Heated Oxygen Sensor (H025) Monitor 1. OBD II Response Rate Monitor: The OBD II Response Rate Monitor (P0133/P0153) is only run at vehicle speeds between approximately 50-95 km/h (30-60 mph), during steady-state conditions. The test lasts approximately 6 seconds. Therefore, P0133/P0153 cannot be diagnosed at idle in the repair bay. 2. Do not compare H025 switch rate - Bank-to-Bank or vehicle-to-vehicle: Different H025 switch rates, from Bank-to-Bank, are considered normal. The H025 switch rate, from one Bank to the other, should not be compared as a gauge of the H025's ability to switch/react. The PCM is continuously adjusting spark and fuel in reaction to engine operating conditions (rpm, load, air flow, throttle angle, etc.). The PCM is also continuously adapting to certain conditions (customer driving habits, engine and component wear, etc.). F3.) Tips Related to Catalyst Efficiency Monitor 1. Determining catalyst efficiency/switch ratio: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4133 The upstream H025 sensors will have a high switch frequency, due to normal closed loop fuel control. With an efficient catalyst, the downstream H025 will have a low switch frequency. The switch ratio is determined by dividing the number of downstream switches by the number of upstream switches over a given period of time. As the catalyst ages (or if the catalyst is damaged or contaminated), the downstream switches will increase. When the downstream switch rate crosses a threshold value (approximately 0.75 switch ratio), a code is stored (P0420 and/or P0430) and the MIL illuminates (refer to Figures 5 and 6). NOTE IF A CATALYST IS DETERMINED TO HAVE LOW EFFICIENCY AND REQUIRES REPLACEMENT, REPLACEMENT OF THE DOWNSTREAM H025 SENSORS WILL NOT BE NECESSARY. 2. Use care in handling H025 sensors: In the event of catalyst replacement, use care in the handling of H025 sensors to prevent damage or contamination. Do not use power tools in the removal or installation of sensors. Use a 22mm wrench or crow foot to remove and install H025 sensors; do not use slotted sockets, as these sockets may damage wires. H025 sensors should be torqued to 41 +/- 5 N.m (30 +/- 4 lb-ft). 3. Do not replace downstream HO2S sensors (H02S12/H02S22) for DTCs P0420 and/or P0430: When diagnosing a vehicle with a customer concern of MIL On and DTCs P0420/P0430 in continuous memory, do not replace the downstream HO2S sensors (H02S12/H02S22). Damaged or malfunctioning downstream HO2S sensors will not cause these DTCs to be set. Always verify the vehicle concern, then perform the pinpoint diagnostics in the appropriate PC/ED Service Manual. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Emissions/Engine Controls - Driveability Diagnosis > Page 4134 F4.) Tips Related to the Fuel System Monitor 1. HO2S sensors are not likely to be the cause of adaptive DTCs P0171, P0172, P0174, P0175: Most warranty-returned HO2S sensors (replaced for these DTCs) are found to function normally. Additional related DTCs will normally be present if there is a concern with the HO2S sensors. Do not replace an HO2S sensor unless verified through pinpoint diagnostic tests found in the PC/ED Service Manual. 2. DTCs P0171, P0172, P0174, and P0175 are not related to downstream H028 sensors: When diagnosing a vehicle with a MIL On and DTC(s) P0171, P0172, P0174, and/or P0175 in continuous memory, do not replace the downstream HO2S sensors. These DTCs have no connection to the downstream HO2S sensor function nor its diagnosis for faults. Always verify the vehicle concern, then perform the pinpoint diagnostics from the appropriate PC/ED Service Manual. 3. Diagnosing lean conditions and lean DTCs P0171, P0174: Freeze Frame Data can often help to identify the type of lean condition, even if the fault is intermittent, by indicating how the vehicle was being driven when the fault occurred. Diagnosis of lean conditions and lean adaptive DTCs can be difficult, especially if the concern is intermittent. Verifying the concern is extremely important. There are different types of lean conditions. The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis. When DTCs P0171 and P0174 are both present, there is a strong likelihood of another concern being present: a. Vacuum leaks/unmetered air: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by air entering the engine through an abnormal source (opening), or due to a MAF malfunction. In this situation, the volume of air entering the engine is actually greater than what the MAF is indicating to the PCM. Vacuum leaks will normally be most apparent when high manifold vacuum is present, during idle or light throttle. If Freeze Frame Data indicates that the fault occurred at idle, a check for vacuum leaks/unmetered air when the engine is cold might be the best starting point. Examples: Loose, leaking or disconnected vacuum lines, intake manifold gaskets or 0-rings, throttle body gaskets, brake booster, air inlet tube, stuck/frozen/aftermarket PCV valve, unseated engine oil dipstick, MAF reading lower than normal, etc. b. Insufficient fueling: In this type of condition, the engine may actually run lean of stoichiometry (14.7:1 air/fuel ratio) if the PCM is not able to compensate enough to correct for the condition. This condition is typically caused by a fuel delivery system concern that restricts or limits the amount of fuel being delivered to the engine. This condition will normally be most apparent when the engine is under a heavy load, when a higher volume of fuel is required. If Freeze Frame Data indicates that the fault occurred under a heavy load, a check of the fuel delivery system (checking fuel pressure with engine under a load) might be the best starting point. Examples: Low fuel pressure (fuel pump, fuel filter, fuel leaks, restricted fuel supply lines), fuel injector concerns, etc. c. Exhaust system leaks: In this type of condition, the engine may actually be running near stoichiometry (14.7:1 air/fuel ratio), but the exhaust gas mixture will be lean. This condition is caused by oxygen-rich air entering the exhaust system through an external source. This condition will cause the exhaust gas mixture to be lean, even though the actual combustion in the engine may not be. Examples: Exhaust system leaks upstream or near HO2S, malfunctioning Secondary Air Injection system d. MAF concerns: If a MAF concern is suspected, see TSB 98-23-10. 4. Checking fuel pressure: Check fuel pressure with engine under a load when diagnosing a lean concern. A partially plugged fuel filter can be difficult to detect and can be easily overlooked if fuel pressure is only checked at idle. The same is true for other types of fuel supply concerns (e.g., bent or kinked lines, degraded fuel pump). At idle, an engine requires only a small volume of fuel. Due to the fact that there is a small volume of fuel needed at idle, a restriction in the fuel supply line in many cases will not cause the fuel pressure to be low. When the vehicle is under a load, the engine requires much more fuel than at idle. Under a load, a restriction in the fuel supply line will prevent the high rate of fuel flow that is needed to maintain the correct fuel pressure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Page 4135 Catalytic Converter: Specifications Three way catalytic converter to exhaust manifold nuts 30 ft.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Page 4136 Generic Catalyst and Exhaust System Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Page 4137 Catalytic Converter: Description and Operation Overview Generic Catalyst and Exhaust System The Catalytic Converter and Exhaust Systems work together to control the release of harmful engine exhaust emissions into the atmosphere. The engine exhaust gas consists mainly of Nitrogen (N), Carbon Dioxide (CO2) and Water Vapor (H2O). However, it also contains Carbon Monoxide (CO), Oxides Of Nitrogen (NOx), Hydrogen (H), and various unburned Hydrocarbons (HCs). CO, NOx, and HCs are major air pollutants, and their emission into the atmosphere must be controlled. The exhaust system generally consists of an exhaust manifold, front exhaust pipe, upstream Heated Oxygen Sensor (HO2S), rear exhaust pipe, downstream HO2S, a muffler and an exhaust tailpipe. The catalytic converter is installed between the front and rear exhaust pipes. Catalytic converter efficiency is monitored by the On Board Diagnostic (OBD II) system. (Refer to OBD II Monitors to Catalyst Efficiency Monitor-Federal Test Procedure for specific information.) Catalytic Converter A catalyst is a material that remains unchanged when it initiates and increases the speed of a chemical reaction. A catalyst will also enable a chemical reaction to occur at a lower temperature. The concentration of exhaust gas products released to the atmosphere must be controlled. The catalytic converter assists in this task. It contains a catalyst in the form of a specially treated honeycomb structure saturated with catalytically active precious metals. As the exhaust gases come in contact with the catalyst, they are changed into mostly harmless products. The catalyst initiates and speeds up heat producing chemical reactions of the exhaust gas components so they are used up as much as possible. Exhaust System The purpose of the exhaust system is to convey engine emissions from the exhaust manifold to the atmosphere. Engine exhaust emissions are directed from the engine exhaust manifold to the catalytic converter through the front exhaust pipe. An HO2S is mounted on the front exhaust pipe before the catalyst. The catalytic converter reduces the concentration of Carbon Monoxide (CO), unburned Hydrocarbons (HCs) and Oxides Of Nitrogen (NOx) in the exhaust emissions to an acceptable level. The reduced exhaust emissions are directed from the catalytic converter to a muffler through the rear exhaust pipe. Another HO2S is mounted on the rear exhaust pipe. Lastly, the exhaust emissions are directed to the atmosphere through an exhaust tailpipe. HARDWARE The downstream HO2S may be located after the light off catalyst or underbody catalyst. The underbody catalyst may be in-line with the light off catalyst, or the underbody catalyst may be common to two light off catalysts, forming a "Y" pipe configuration. For an exact configuration of the catalyst and exhaust system, refer to Exhaust System. Three Way Catalytic Converter The Three Way Catalytic (TWC) converter contains either Platinum (Pt) and Rhodium (Rh) or Palladium (Pd) and Rhodium (Rh). The TWC converter catalyzes the oxidation reactions of unburned HCs and CO and the reduction reaction of NOx. The three-way conversion can br brst accomplished by always operating the engine air fuel/ratio at or close to stoichiometry. Exhaust Manifold/Runners The exhaust manifold runners collect exhaust gases from engine cylinders. The number of exhaust manifolds and exhaust manifold runners depends on Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Page 4138 the engine configuration and number of cylinders. Exhaust Pipes Exhaust pipes are usually treated during manufacturing with an anti-corrosive coating agent to increase the life of the product. The pipes serve as guides for the flow of exhaust gases from the engine exhaust manifold through the catalytic converter and the muffler. Upstream Heated and Downstream Heated Oxygen Sensors The HO2S provide the Powertrain Control Module (PCM) with voltage and frequency information related to the oxygen content of the exhaust gas. (Refer to the PCM Inputs for a description of how the H02S operates.) In addition to providing the PCM with indications of how rich/lean the engine is operating, the upstream HO2S signal serves as an input to the H02S monitor. The downstream HO2S signal is an input to the Catalyst Efficiency monitor. (Refer to the OBD II Monitors for specific information on these monitors.) Muffler Mufflers are usually treated during manufacturing with an anti-corrosive coating agent to increase the life of the product. The muffler reduces the level of noise produced by the engine, and it also reduces the noise produced by exhaust gases as they travel from the catalytic converter to the atmosphere. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Technical Service Bulletins > Page 4139 Catalytic Converter: Service and Repair Removal and Installation All vehicles 1.

The fuel filler pipe forms a seal to prevent vapors from escaping the fuel tank, while liquid is entering the fuel tank (liquid in the one inch diameter tube blocks vapors from rushing back up the fuel filler pipe). 2. A fuel vapor control valve controls the flow of vapors out of the fuel tank (valve closes when liquid level reaches a height associated with the fuel tank usable capacity). This valve accomplishes the following: a. Limits the total amount of fuel that can be dispensed into the fuel tank. b. Prevents liquid gasoline from exiting the fuel tank when submerged (and also when tipped well beyond a horizontal plane as part of the vehicle roll-over protection in road accidents). c. Minimizes vapor flow resistance during anticipated refueling conditions. 3. Fuel vapor tubing connects the fuel vapor control valve to the EVAP canister. This routes the fuel tank vapors (displaced by the incoming liquid) to the EVAP canister. 4. A check valve in the bottom of the fuel filler pipe prevents liquid from rushing back up the fuel filler pipe during the liquid flow variations associated with the filler nozzle shut-off. Between refueling events, the EVAP canister is purged with fresh air so that it may be used again to store vapors accumulated engine soaks or subsequent refueling events. The vapors drawn off of the carbon in the EVAP canister are consumed in the engine. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Backpressure Transducer > Component Information > Specifications EGR Backpressure Transducer: Specifications EGR back pressure transducer nuts 71 - 106 in.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Electronic Vacuum Regulator Solenoid > Component Information > Specifications EGR Electronic Vacuum Regulator Solenoid: Specifications EGR Vacuum Regulator Solenoid Bolts/Nuts 6 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Electronic Vacuum Regulator Solenoid > Component Information > Specifications > Page 4197 EGR Electronic Vacuum Regulator Solenoid: Locations LH Component RH Component Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Electronic Vacuum Regulator Solenoid > Component Information > Description and Operation > EGR Vacuum Regulator Solenoid EGR Electronic Vacuum Regulator Solenoid: Description and Operation EGR Vacuum Regulator Solenoid EGR Vacuum Regulator Solenoid EGR Vacuum Regulator Solenoid EGR Vacuum Regulator Solenoid Graph EGR Vacuum Regulator Solenoid Data The EGR vacuum regulator solenoid is an electromagnetic device which is used to regulate the vacuum supply to the EGR valve. The solenoid contains a coil which magnetically controls the position of a disc to regulate the vacuum. As the duty cycle to the coil increases, the vacuum signal passed through the solenoid to the EGR valve also increases. Vacuum not directed to the EGR valve is vented through the solenoid vent to atmosphere. Note that at 0% duty cycle (no electrical signal applied), the EGR vacuum regulator solenoid allows some vacuum to pass, but not enough to open the EGR valve. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Electronic Vacuum Regulator Solenoid > Component Information > Description and Operation > EGR Vacuum Regulator Solenoid > Page 4200 EGR Electronic Vacuum Regulator Solenoid: Description and Operation General The EGR vacuum regulator solenoid uses input from the PCM to change the EGR valve operation. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Electronic Vacuum Regulator Solenoid > Component Information > Description and Operation > Page 4201 EGR Electronic Vacuum Regulator Solenoid: Service and Repair REMOVAL 1.

The valve increases or decreases the flow of exhaust gas recirculation. As vacuum applied to the EGR valve diaphragm overcomes the spring force, the valve begins to open. As the vacuum signal weakens, at 5.4 kPa (1.6 in-Hg) or less, the spring force closes the valve. The EGR valve is fully open at about 15 kPa (4.5 in-Hg). Since EGR flow requirement varies greatly, providing service specifications on flow rate is impractical. The on-board diagnostic system monitors the EGR valve function and triggers a Diagnostic Trouble Code if the test criteria is not met. The EGR valve flow rate is not measured directly as part of the field diagnostic procedures. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Emission Control Systems > Exhaust Gas Recirculation > EGR Valve > Component Information > Specifications > Page 4217 EGR Valve: Service and Repair REMOVAL 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4274 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4275 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4276 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4277 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4278 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4279 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4280 Accelerator Pedal: Connector Views Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4281 Accelerator Pedal: Electrical Diagrams Diagram 127-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4282 Diagram 127-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Diagram Information and Instructions > Page 4283 Diagram 127-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Diagrams > Page 4284 Accelerator Pedal: Description and Operation The throttle is controlled by an accelerator cable attached to the accelerator pedal and shaft assembly. The accelerator pedal and shaft should travel smoothly from the idle position to the wide open throttle position. Hesitation or binding should not be experienced at any portion of the accelerator pedal and shaft travel. Surrounding components such as wiring, hoses, sound insulator and floor carpet must not contact the sliding inner member of the accelerator cable, or interfere with the accelerator pedal and shaft. The vehicle is also available with an adjustable pedals option. This allows both the accelerator and brake pedals to be adjusted simultaneously forward or rearward. A rocker switch on the instrument panel provides adjustment on the pedals assembly when it is activated. On vehicles with the memory seat option, the pedals position can be controlled by the memory selection, as well as the rocker switch. The accelerator pedal and shaft can still be serviced separately on the adjustable pedals assembly. The components in the acceleration control system are not adjustable and must be replaced if damaged or worn. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Accelerator Pedal > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview Accelerator Pedal: Initial Inspection and Diagnostic Overview 1.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling. Diagram Of Air Flow Through Throttle Body Containing MAF Sensor Hot And Cold Wire (and IAT Sensor Where Applicable) Terminals Some MAF sensors have Integrated Bypass Technology (IBT) with an integrated Intake Air Temperature (IAT) sensor. The present applications with IBT are: Focus, Escort (4V), 2.0 L Contour/Mystique, Cougar, Taurus/Sable, Windstar, Explorer/Mountaineer and E-Series. The MAF sensor is located between the air cleaner and the throttle body or inside the air cleaner assembly. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Description and Operation > Page 4311 Mass Air Flow Sensor: Service and Repair REMOVAL 1. Open the air cleaner. ^ Disconnect the MAF sensor extension harness connector from the wiring harness. ^ Release the air cleaner clamp. ^ Separate the inlet side of the air cleaner from the outlet side of the air cleaner. CAUTION: Do not tamper with the sensing elements located in the Mass Air Flow (MAF) sensor. Tampering may result in unit failure. NOTE: The MAF sensor module and body are calibrated and serviced as a unit. 2. Cut the tape on the wire loom of the extension harness. ^ Peel back the wire loom from the extension harness near the grommet in the air cleaner. 3. Remove the grommet from the outlet side of the air cleaner and slide the grommet down the extension harness. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Description and Operation > Page 4312 4.

It regulates fuel pressure supplied to the fuel injectors. The regulator is a diaphragm-operated relief valve. One side of the diaphragm senses fuel pressure and the other side is connected to the intake manifold vacuum. Fuel pressure is established by a spring preload applied to the diaphragm. Balancing one side of the diaphragm with manifold vacuum maintains a constant fuel pressure drop across the fuel injectors. Fuel pressure is high when engine vacuum is low. Excess fuel is bypassed through the fuel pressure regulator and returned through the fuel return line to the fuel tank. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pressure Regulator > Component Information > Description and Operation > Fuel Pressure Regulator > Page 4377 Fuel Pressure Regulator: Description and Operation General The fuel pressure regulator: ^ maintains constant fuel pressure throughout the fuel system and to the fuel injectors. ^ is spring-loaded and operated by intake manifold vacuum. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pressure Regulator > Component Information > Description and Operation > Page 4378 Fuel Pressure Regulator: Service and Repair REMOVAL WARNING: ^ DO NOT SMOKE OR CARRY LIGHTED TOBACCO OR OPEN FLAME OF ANY TYPE WHEN WORKING ON OR NEAR ANY FUEL RELATED COMPONENTS.

Install the EVAP Emission Test Port Adapter that is provided with the Rotunda's Smoke Machine to EVAP Canister Purge Valve test port. NOTE SPECIAL PROCEDURES HAVE BEEN DESIGNATED FOR WINDSTAR, LS, THUNDERBIRD & PZEV FOCUS BECAUSE THEY HAVE A CHECK VALVE THAT WILL PREVENT SMOKE FROM ENTERING THE FILLER NECK. 6. Connect black smoke hose nozzle tip to the EVAP Emission Test Port Adapter. For all except Windstar, LS, Thunderbird & PZEV Focus Use NGS or WDS to close CVS. (CVS WILL REOPEN AFTER NINE (9) MINUTES OF CONTINUOUS OPERATION). 7. For all except Windstar, LS, Thunderbird & PZEV Focus - Remove the fuel cap from the vehicle. Depress remote starter button: Smoke will be introduced into the EVAP Emission System. Secure the fuel cap once smoke is seen exiting from the fuel tank's neck area. For Windstar, LS, Thunderbird & PZEV Focus, do not remove fuel cap. Depress starter button and introduce smoke to system until it can be seen exiting the CVS (located by filler neck). Once smoke is seen, use NGS or WDS to close CVS. (CVS WILL REOPEN AFTER NINE (9) MINUTES OF CONTINUOUS OPERATION). 8. Press and release the remote starter button in intervals of approximately 15 seconds on and 15 seconds off. Use the halogen light provided with the Smoke Machine to look for smoke in the engine compartment, EVAP hoses to EVAP Canister Purge Valve, CVS, carbon canister and area around the fuel cap. Wiggle fuel vapor lines to check for leaks. Check for leaks in areas that are difficult to access, such as connections on top of the tank where connections may be or inside frame rails. Use the black light to ensure that there are no leaks. If a leak is detected, repair as necessary. If the leak is not detected from the top, check under the bottom of vehicle. Inspect the EVAP hoses running to the carbon canister, fuel filler neck, CVS, and EVAP Canister Purge Valve. Go to LEAK VERIFICATION to verify any repair or if no leak is found. LEAK VERIFICATION (METERED AIR SYSTEM) 1. Position the selector valve located on the Smoke Machine control panel to "METER". 2. Verify calibration of the flow meter by using the .020" calibrated leak orifice. To do this, insert air supply hose (transparent hose) nozzle tip into appropriate EVAP System calibrated leak orifice located on the front of the Smoke Machine panel. 3. TURN ON: Depress the remote starter button. Observe the position of the flow meter indicator ball. Position the flow meter red pointer flag so it aligns with the measurement of the indicator ball. Release the button and remove the air supply hose nozzle tip from the EVAP System calibrated leak orifice. NOTE THIS FLOW METER CALIBRATION MEASUREMENT INDICATES THE VEHICLE PASS OR FAIL CRITERIA BASED ON THE .020" EVAP SYSTEM LEAK STANDARD. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank > Fuel Filler Neck > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Fuel Filler Neck: > 03-20-3 > Oct > 03 > Emissions - MIL ON/DTC's Stored/Check Fuel Cap Lamp ON > Page 4450 4. Connect the transparent air supply hose nozzle tip into the EVAP Service Test Port adapter. 5. Use NGS or WDS Diagnostic tool to CLOSE the CVS. 6. Depress the remote starter button on the Rotunda's Smoke Leak Detector. The indicator ball in the flowmeter will go all the way to the top indicating the system is being pressurized. Continue to depress the remote starter button until the ball stops descending. Once the indicator ball has stopped descending, observe if it is above or below the red indicator flag. If performing this verification following a repair, go to Step 7. If performing this verification after performing the SYSTEM LEAK CHECK (SMOKE TEST PROCEDURE), go to Step 8. 7. Leak Verification After Repair a. If the measurement is below the indicator flag the system has passed. The test procedure is complete. Remove the Smoke Machine Test equipment from the vehicle and reconnect the large EVAP Canister Purge Valve manifold vacuum hose and the test port's green cap. b. If the measurement is above the indicator flag, repeat SYSTEM LEAK CHECK (SMOKE TEST PROCEDURE). 8. Leak Verification After Passing SYSTEM LEAK CHECK (SMOKE TEST PROCEDURE) a. If the measurement is below the indicator flag the system has passed, go to Step 9. b. If the measurement is above the indicator flag, repeat SYSTEM LEAK CHECK (SMOKE TEST PROCEDURE). 9. Using WDS Datalogger or NGS select the FTPV PID. 10. Remove Fuel Cap and turn the vehicle's ignition switch to the run position and check the FTPV PID. 11. The nominal value for the FTPV PID is 2.6V. If the value is greater than 2.8V or less than 2.4V, the FTP sensor is out of range and should be replaced. Verify the repair by checking to see if the new sensor is in range. For all except Windstar, LS, Thunderbird & PZEV Focus - if the sensor is within range, the concern is no longer present. (Windstar, LS, Thunderbird & PZEV Focus go to Step 12.) 12. For Windstar, LS, Thunderbird & PZEV Focus only verify that filler neck clamps are in good working order and tightened. Repair as necessary. If no problem is found with clamps, replace the fuel cap.

The IAC valve assembly meters intake air around the throttle plate through a bypass within the IAC valve assembly and throttle body. The PCM determines the desired idle speed or bypass air and signals the IAC valve assembly through a specified duty cycle. The IAC valve responds by positioning the IAC valve to control the amount of bypassed air. The PCM monitors engine rpm and increases or decreases the AC duty cycle in order to achieve the desired rpm. On applications with air-assisted injectors, the IAC valve also supplies a small amount of air into the path of the fuel injectors. The jet of air causes an Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Idle Air Control Valve <--> [Idle Speed/Throttle Actuator - Electronic] > Component Information > Description and Operation > General > Page 4463 increase in fuel atomization at low speed and light load conditions. NOTE: The IAC Valve Assembly is NOT ADJUSTABLE and CANNOT BE CLEANED. The IAC valve (part of throttle body assembly) has an internal diode on some applications. If the internal diode is measured in crossed terminal position with a digital multimeter, there will be an incorrect or negative reading. It is important that the mating component and harness connectors are correctly oriented. Diagnostic procedures emphasize this importance. The PCM uses the IAC valve assembly to control: ^ No touch start ^ Cold engine fast idle for rapid warm-up ^ Idle (corrects for engine load) ^ Stumble or stalling on deceleration (provides a dashpot function) ^ Over-temperature idle boost. ^ Air Assist to Injectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Idle Air Control Valve <--> [Idle Speed/Throttle Actuator - Electronic] > Component Information > Description and Operation > Page 4464 Idle Air Control Valve: Testing and Inspection Idle Air Control (IAC) Valve Check 1. Open the hood. 2. Verify the condition by operating the vehicle for a short time. NOTE: ^ Key symptom is elevated idle speed while noise is occurring. ^ "Snapping" the throttle can induce the noise. 3. Inspect the IAC valve. If physical evidence of contamination exists, install a new IAC valve. 4. While the noise is occurring, either place an EngineEAR probe near the IAC valve and the inlet tube, or create a 6.35 mm (0.25 in)-12.7 mm (0.50 in) air gap between the inlet tube and the clean air tube.

The purpose of the IFS switch is to shut off the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle. Refer to the Owner Guide for the location of the IFS. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Intake Air Duct > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Intake Air Duct > Component Information > Locations > Page 4472 Intake Air Duct: Service Precautions CAUTION: The air cleaner outlet tube should be securely sealed to prevent unmetered air from entering the engine. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Intake Air Duct > Component Information > Locations > Page 4473 Intake Air Duct: Service and Repair REMOVAL 1.

Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission Electronic Pressure Control (EPC), shift and torque converter clutch scheduling. Diagram Of Air Flow Through Throttle Body Containing MAF Sensor Hot And Cold Wire (and IAT Sensor Where Applicable) Terminals Some MAF sensors have Integrated Bypass Technology (IBT) with an integrated Intake Air Temperature (IAT) sensor. The present applications with IBT are: Focus, Escort (4V), 2.0 L Contour/Mystique, Cougar, Taurus/Sable, Windstar, Explorer/Mountaineer and E-Series. The MAF sensor is located between the air cleaner and the throttle body or inside the air cleaner assembly. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Mass Air Flow Sensor <--> [Air Flow Meter/Sensor] > Component Information > Description and Operation > Page 4504 Mass Air Flow Sensor: Service and Repair REMOVAL 1.

This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each engine combustion cylinder. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Inertia Fuel Shutoff Switch > Component Information > Description and Operation Inertia Fuel Shutoff Switch: Description and Operation Inertia Fuel Shutoff (IFS) Switch Inertia Fuel Shutoff (IFS) Switch The Inertia Fuel Shutoff (IFS) switch is used in conjunction with the electric fuel pump. The purpose of the IFS switch is to shut off the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle. Refer to the Owner Guide for the location of the IFS. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > General Throttle Position Sensor: Description and Operation General The TP sensor: ^ sends the PCM a signal indicating the throttle plate angle. ^ is the main input to the PCM from the driver. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > General > Page 4517 Throttle Position Sensor: Description and Operation Throttle Position Sensor Throttle Position Sensor Throttle Position (TP) Sensor The Throttle Position (TP) sensor is a rotary potentiometer sensor that provides a signal to the PCM that is linearly proportional to the throttle plate/shaft position. The sensor housing has a three-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and increases connector durability. The TP sensor is mounted on the throttle body. As the TP sensor is rotated by the throttle shaft, four operating conditions are determined by the PCM from the TP. Those conditions are closed throttle (includes idle or deceleration), part throttle (includes cruise or moderate acceleration), wide open throttle (includes maximum acceleration or de-choke on crank), and throttle angle rate. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Description and Operation > Page 4518 Throttle Position Sensor: Service and Repair REMOVAL 1.

The accelerator pedal and shaft should travel smoothly from the idle position to the wide open throttle position. Hesitation or binding should not be experienced at any portion of the accelerator pedal and shaft travel. Surrounding components such as wiring, hoses, sound insulator and floor carpet must not contact the sliding inner member of the accelerator cable, or interfere with the accelerator pedal and shaft. The vehicle is also available with an adjustable pedals option. This allows both the accelerator and brake pedals to be adjusted simultaneously forward or rearward. A rocker switch on the instrument panel provides adjustment on the pedals assembly when it is activated. On vehicles with the memory seat option, the pedals position can be controlled by the memory selection, as well as the rocker switch. The accelerator pedal and shaft can still be serviced separately on the adjustable pedals assembly. The components in the acceleration control system are not adjustable and must be replaced if damaged or worn. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Cable/Linkage > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview Throttle Cable/Linkage: Initial Inspection and Diagnostic Overview 1.

The IMT valve actuator controls a shutter device attached to the actuator shaft. There is no monitor input to the PCM with this system to indicate shutter position. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Intake Manifold Runner Control <--> [Variable Induction System] > Variable Induction Control Valve > Component Information > Description and Operation > Page 4552 The IMT valve motorized unit will not be energized below approximately 2600 rpm or higher on some vehicles. The shutter will be in the closed position not allowing airflow blend to occur in the intake manifold. Above approximately 2600 rpm or higher, the motorized unit will be energized. The motorized unit will be commanded on by the PCM initially at a 100 percent duty cycle to move the shutter to the open position and then falling to approximately 50 percent to continue to hold the shutter open. 1. The PCM uses the TP sensor and CKP signals to determine activation of the IMT valve system. There must be a positive change in voltage from the TP sensor along with the increase in rpm to open the shutter. 2. The PCM uses the information from the input signals to control the IMT valve. 3. When commanded on by the PCM, the motorized actuator shutter opens up the end of the vertical separating wall at high engine speeds to allow both sides of the manifold to blend together. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Firing Order > Component Information > Specifications Firing Order: Specifications V8 Firing Order: 1 3 7 2 6 5 4 8 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Firing Order > Component Information > Specifications > Page 4557 Firing Order: Locations V8 Firing Order: 1 3 7 2 6 5 4 8 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Timing > Number One Cylinder > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Specifications Camshaft Position Sensor: Specifications Camshaft position sensor bolt 71 - 106 in.lb Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Specifications > Page 4565 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Description and Operation > General Camshaft Position Sensor: Description and Operation General The CMP sensor: ^ sends the PCM a signal indicating camshaft position used for fuel synchronization. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Description and Operation > General > Page 4568 Camshaft Position Sensor: Description and Operation 2000 All (Except diesel/Propane/Villager) Camshaft Position Sensor The Camshaft Position (CMP) sensor detects the position of the camshaft.

NOTE FOLLOW THIS TSB PROCEDURE ONLY IF THERE ARE NO SPECIFIC MISFIRE TSBs/SSMs RELEASED FOR THE VEHICLE SYMPTOM BEING EXPERIENCED. ISSUE Approximately 50% of coil on plug (COP) coils returned for warranty do not have a problem. ACTION The misfiring cylinder must be identified through Self-Test misfire codes or through WDS Power Balance. Rule out base engine problems, rule out fuel problems, and then look at ignition problems (be sure to rule out coil primary circuit issues). Once the above steps have been completed, and the issue is in the secondary part of the ignition system, the oscilloscope procedure outlined in this TSB can isolate the difference between a coil or spark plug problem. SERVICE PROCEDURE The optional WDS COP Kit available through Rotunda will provide more accurate diagnosis and help reduce replacement of non-defective parts. The Kit (418-F5528) can be purchased through 1-800-ROTUNDA. The following material will detail the diagnostic steps on WDS to take the guesswork out of misfire diagnosis using the COP Kit. The following Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4583 procedure is for cylinder specific misfires and not random misfires. Random misfires have a different root cause and are not covered by this TSB. Misfire Definition: A misfiring cylinder is lacking power relative to the other cylinders. The causes for a cylinder specific misfire could be fuel, spark, or mechanical problems. Perform a thorough visual inspection. If no visible concerns are found use the following WDS tools for misfire diagnosis: ^ Self-test (Check for codes first) Power Balance (Identify the cylinder of concern) ^ Relative Compression (Rule out a possible mechanical issue) ^ Fuel (Make sure fuel injectors are not restricted) ^ Ignition (Make sure spark plugs and coils are working properly) ^ Oscilloscope (Detailed signal analysis) NOTE USE THE ENCYCLOPEDIA BUTTON IN THE LOWER LEFT CORNER OF THE SCREEN FOR DETAILED INFORMATION ON THE WDS TOOL BEING DISPLAYED. If there is a self-test code identifying a particular cylinder then you just need to determine if it is a fuel, ignition, or possibly a mechanical problem. Proceed to Step 2 after running Relative Compression to rule out any mechanical issues. If there is no self-test code and the customer concern is a miss, proceed to Step 1. Step 1: (Select Toolbox Icon, then Powertrain, then Power Balance) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4584 The cylinder specific miss has to be identified as shown in the example in Figure 2 in order to proceed with the remaining steps. If the miss does not occur at idle (in the bay), try to brake torque the engine. This extra loading should reproduce the miss in the bay. If the miss cannot be reproduced during brake torque, select Relative Compression under Powertrain on WDS before going on a road test to rule out mechanical problems. If Relative Compression shows a problem then the base engine issue must be serviced. If Relative Compression results are good (Figure 3), road test under as many different driving conditions as possible until the miss occurs on Power Balance. Some misses may be very intermiffent so be patient and concentrate on steady load conditions. Once a cylinder dropout is identified proceed to Step 2. Step 2: (Select Toolbox Icon, then Powertrain, then Fuel System Test) Run Fuel System Test on WDS to determine if there may be a fuel problem. After completing fuel Pressure/Leakdown test, select Injector flow to isolate Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4585 a restricted injector as shown in Figure 4. If all the injectors are within specification, proceed to Step 3. Step 3: (Select Toolbox Icon, then Powertrain, then Ignition System Test) Run Ignition System Test on WDS to determine if there is an ignition problem. Look at both duration (DUR) and kilovolts (KV) and look for values that standout from the rest as shown in Figure 5 and Figure 6. NOTE LIVE DISPLAY HAS TO AVERAGE IGNITION VALUES BECAUSE THERE IS TOO MUCH DATA TO DISPLAY. MAKE A CAPTURE TO VIEW EACH ENGINE EVENT WITHOUT AVERAGING. THIS CAN BE HELPFUL WHEN THE PROBLEM IS INTERMITTENT. IF THE Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4586 MISS IS EXTREMELY INTERMITTENT AND DOES NOT SHOW UP IN IGNITION, PROCEED TO STEP 4. If either spark duration or peak KV on the Red Probe (Suspect Cylinder) are offset from the values displayed on the Black Probe (Known Good Cylinder) then the problem is in the ignition system. Rule out coil primary circuit issues before proceeding to coil secondary issues such as the spark plug , coil boot, or possibly the coil. Use the WDS Oscilloscope with the COP kit to determine if the issue is the coil or the spark plug. Step 4: (Select Toolbox, then Oscilloscope) WARNING SECONDARY IGNITION VOLTAGES ARE VERY HIGH. KEEP HANDS AND TOOLS AWAY FROM THE END OF THE COIL THAT SUPPLIES THE SPARK. SET-UP: With the engine off, pull the suspect coil from the cylinder well and turn it upside down so the coil cannot spark to any other surface as shown in Figure 1. Wrap a clean shop cloth around the hard shell of the coil to help keep the coil propped up and stable. CAUTION THE COIL BOOT CAN BE DAMAGED IF THE COIL SPARKS TO ANOTHER SURFACE DURING THIS PROCEDURE. Keep the coil connected to the harness and leave the WDS COP clip attached to the coil. Route the coil clip wire and cable away from the coil being tested as well as other coils to avoid noise interference. Disconnect the injector of the cylinder being tested so raw fuel is not washing the cylinder. This is a stress test for the coil. The type of waveform displayed on the oscilloscope will show whether a coil or the plug is the problem if all previous steps have been followed. Keep hands and tools away from the end of the coil that supplies the spark. COP Stress Test Procedure: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4587 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Technical Service Bulletins > Ignition System - Coil-On-Plug Misfire Diagnostic Tips > Page 4588 Go to the Oscilloscope Tool and select Channel 3, then select Auto, then select COP_STRESS_TEST_RED. This pre-configured setting will zoom-in on the peak firing of the coil being tested. Start the engine and be sure the coil is not sparking to any surface. If the coil is sparking to other surfaces, turn the engine off immediately and readjust the coil so it cannot spark to any other surface. Restart the engine and touch the Red Man icon to start the oscilloscope. All settings are pre-configured and no adjustments are necessary. Compare the waveform you get with the examples provided in Figures 7, 8, and 9). Figure 7 is a good waveform. If your waveform is similar to Figure 7 the coil is working correctly. Suspect the spark plug. Figure 8 and Figure 9 are examples of problem coils. Replace the coil if the waveform is similar to Figures 8 or 9. The coil is causing the misfire when the peak firing appears like those shown in Figures 8 and 9. Notice the difference in the peak-firing signal when compared to the good peak signal in Figure 7. Figure 9 shows a more dramatic fault in the peak failure. Most root causes of misfire issues can be identified quickly using the steps outlined above. Some misfire issues can be difficult making the oscilloscope an important part of your diagnostic toolbox.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 4682 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

ISSUE PCMs may need to be reprogrammed or replaced as part of a repair. Additional vehicle concerns may be caused if proper programming procedures are not followed. ACTION Use the following procedure to reprogram PCMs. Verify repair after reprogramming. SERVICE PROCEDURE PRELIMINARY STEPS - Existing PCM Reprogramming Or PCM Replacement 1. Connect a battery charger to vehicle. 2. Use WDS if available. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 04-24-14 > Dec > 04 > Engine Controls - General PCM Programming Procedures > Page 4711 a. Make sure WDS is docked or attached to vehicle battery supply. b. Verify WDS software is at the latest release level. 3. If there is a communication error, attempt to communicate with a different diagnostic scan tool, such as NGS, NGS+, VCM or another WDS. NOTE IF COMMUNICATION STILL CANNOT BE ESTABLISHED, VOLTAGE DROP PCM POWERS, GROUNDS, AND CHECK VREF. PCM REPLACEMENT - STANDARD 1. Open WDS vehicle session with original PCM installed in vehicle. If the original PCM is not able to communicate, to open a session, proceed to the Blank Path Programming procedure. 2. Install the new PCM. NOTE IF WDS NEEDS TO BE USED ON A DIFFERENT VEHICLE WHILE THE NEW PCM IS BEING INSTALLED, PLACE THE VEHICLE SESSION ON "HOLD" FOR USE LATER. 3. Attempt to start the vehicle. 4. Run KOEO Self Test to check for diagnostic trouble codes (DTCs) in PCM. 5. Check for DTC P0602/P0605/P1639. a. If DTC P0602/P0605/P1639 is present then Programmable Module Installation (PMI) procedure must be performed. Use the WDS session opened at Step 1. b. If DTC P0602/P0605/P1639 is not present, then verify Programmable Parameters are properly set such as tire size, axle ratio, etc. 6. Check for DTC B2900. a. If DTC B2900 is present, perform PMI on the ABS module. Do Not replace ABS module for this procedure when directed. You may be prompted to enter the 9 lines of PCM As-Built data during this procedure. b. If DTC B2900 is not present proceed to Step 7. 7. Diagnose all other DTCs following normal diagnostic procedures. REPROGRAMMING DOES NOT COMPLETE OR FAILS - Existing PCM Reprogramming Or PCM Replacement 1. Verify all cables are properly connected. 2. Verify vehicle battery is at proper charge level. 3. Verify scan tool battery is at proper charge level. 4. Attempt reprogramming procedure again. 5. If reprogramming still does not complete properly, save current session, reboot WDS, open previous session, and attempt reprogramming again. 6. If reprogramming still does not complete or you are now unable to communicate with PCM, proceed to the Blank Path Programming procedure. BLANK PATH PROGRAMMING - Existing PCM Reprogramming Or PCM Replacement Perform this procedure prior to PCM replacement if a vehicle comes in with a PCM that will not communicate, or if steps earlier in this TSB directed you to this procedure. 1. Verify powers and grounds to PCM by loading and voltage drop testing circuits. 2. Follow Pin Point Tests to verify network integrity.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches - A/T > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 4861 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

ISSUE The number one cause for repeat transmission repairs is that contamination from the transmission cooler system (lines and tank) will work their way back into the rebuilt or new transmission. For this reason a new transmission cooler flusher has been released, "Turbo-Tank Heated Cooler Line Flusher" Rotunda Tool number 22-00001. ACTION The transmission cooling system (cooler and lines) MUST be flushed every time the transmission is overhauled or replaced in order to minimize the likelihood of repeat repairs. The use of this new "Turbo-Tank Heated Cooler Line Flusher" (222-00001) is the most effective way to remove contamination from its cooling system. Refer to the following Service Procedure and Equipment instructions (supplied with the "Turbo-Tank Heated Cooler Line Flusher"). SERVICE PROCEDURE Prior methods of cooler flushing have not obtained the level of cooler cleaning and contaminant removal that is required to prevent repeat repairs. The "Turbo-Tank Heated Cooler Line Flusher" uses heated Automatic Transmission Fluid (ATF) and a pulsating action to loosen system contamination. Previous equipment used solvents to clean & flush coolers, lines and torque-converters. There are 2 issues with this method: Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Cooler, A/T > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Service Tips > Page 4910 ^ Residual solvent contamination can cause damage to friction bonding materials within the transmission (Clutches and Bands). ^ Lack of fluid heating and agitation prevents this method from completely removing contamination from lines, in-radiator coolers and auxiliary coolers. Aerosol Solvents should never be used for several reasons. ^ They do not provide the volume necessary to remove heavy contaminants. ^ They evaporate quickly and essentially leave contaminants in pockets, bends, or wherever they are as the solvent dries. NOTE YOU MUST IDENTIFY THE RETURN COOLER LINE TO START THE BACK FLUSHING PROCEDURE. A quick way to identify the return cooler line (fluid coming out of the cooler and returning to the transmission) is to locate the return cooler line fitting on the transmission case. Refer to the following lists: Rear Wheel Drive ^ TORQSHIFT, 4R100, E40D, C6 - The REAR transmission case filling receives the return line. ^ 4R70W, AODE, AOD - The TOP transmission case filling receives the return line. ^ A4LD, 4R44/55E, 5R55E, 5R55N, 5R55W, 5R55S - The TOP transmission case filling receives the return line. Front Wheel Drive ^ CD4E - The REAR or Pump End transaxle case fitting receives the return line. ^ 4F27E - The REAR or Cover End transaxle case fitting receives the return line. ^ AXOD, AXODE, AX4S, AX4N, 4F50N - The BOTTOM transaxle cooler line fitting receives the return line. NOTE IF AN IN-LINE FILTER HAS BEEN INSTALLED IN THE COOLER LINE, IT MUST BE REMOVED BEFORE FLUSHING THE COOLER OR COOLER LINES. Purge the cooler and cooler line before flushing: Located on the "Turbo-Tank Heated Cooler Line Flusher" is a fluid transfer and purge valve. This valve can be used to purge the cooler and cooler lines of contaminated fluid before starting the back flush procedure of the fluid cooling system (refer to step 5a of this Service Procedure or Equipment instructions, supplied with the "Turbo-Tank Heated Cooler Line Flusher"). Flush Procedure 1. Check and top off fluid level of the "Turbo-Tank Heated Cooler Line Flusher" tank with transmission fluid. 2. Allow the fluid in the flusher 15-30 minutes to heat up to 140° F (60° C) before using. 3. Install line adapters into the transmission cooler lines. 4. Attach the flusher's blue line to the transmission return cooler line quick disconnect. 5. Attach the flusher's red line to the transmission outlet cooler line quick disconnect. a. Follow equipment instructions, to purge cooler lines and cooler prior to starting flushing procedure (using factory installed purge valve and clear hose on "Turbo-Tank Heated Cooler Line Flusher"). 6. Allow the cooling system to back-flush for 10-15 minutes, then flush the cooler in a forward/normal flow direction for an additional 10-15 minutes.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 4935 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 5207 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Digital Transmission Range Sensor <--> [Transmission Position Switch/Sensor, A/T] > Component Information > Diagrams > Page 5294 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

Brake System Pressure Bleeding WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water. Note: When any part of the hydraulic system has been disconnected for repair or new installation, air may get into the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or with pressure bleeding equipment. Note: Bleed the longest line first. Be sure the bleeder tank contains enough specified brake fluid to complete the bleeding operation. 1.

Four Wheel Antilock Brake System Bleeding WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water. Note: When any part of the hydraulic system has been disconnected for repair or new installation, air may get into the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or with pressure bleeding equipment. Note: This procedure must be performed if the 4 wheel anti-lock brake (4WABS) hydraulic control unit (HCU) has been installed new. Note: One conventional pressure bleed cycle consists of advancing the brake pedal to its depressed position, opening the disc brake caliper bleeder screw, allowing fluid to be released into the waste container, closing the disc brake caliper bleeder screw and releasing the brake pedal. Note: Performing the NGS program routine drives entrapped air from the otherwise inaccessible lower section of the 4WABS valve into the upper sections (accessible by bleeding the brakes). Subsequent bleedings remove the air from the system. Note: Add recommended brake fluid as necessary throughout the procedure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Bleeding > System Information > Service and Repair > Brake Master Cylinder - Bench Bleed > Page 5349 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5365 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5366 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5367 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5368 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5369 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5370 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5371 Brake Pedal Assy: Connector Views Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5372 Brake Pedal Assy: Electrical Diagrams Diagram 127-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5373 Diagram 127-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Diagram Information and Instructions > Page 5374 Diagram 127-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Diagrams > Page 5375 Brake Pedal Assy: Testing and Inspection For further information regarding this component and the system that it is a part of, please refer to Brakes and Traction Control; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Brake Pedal Assy > Component Information > Service and Repair > Brake Pedal Brake Pedal Assy: Service and Repair Brake Pedal Removal 1.

The brake master cylinder is assisted by a power brake booster. The following conditions are considered normal, and are not indications that the brake master cylinder is in need of repair or replacement: ^ Low brake fluid level detected without signs of leakage. This condition is caused by displacement of brake fluid from the brake master cylinder reservoir into the disc brake calipers to compensate for normal brake wear. Add brake fluid as needed. ^ A momentary or slight ripple of brake fluid inside the brake master cylinder reservoir upon application or release of the brake pedal. ^ A trace of brake fluid found on the outside of the power brake booster below the brake master cylinder mounting flange. This condition results from the lubricating action of the brake master cylinder wiping seal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Master Cylinder > Component Information > Specifications > Page 5500 Brake Master Cylinder: Testing and Inspection Normal Conditions The following conditions are considered normal and are not indications that the brake master cylinder is in need of service. Condition 1: During normal operation of the brake master cylinder, the fluid level in the brake master cylinder reservoir will rise during brake application and fall during release. The net fluid level (i.e., after brake application and release) will remain unchanged. Condition 2: A trace of brake fluid will exist on the booster shell below the master cylinder mounting flange. This results from the normal lubricating action of the master cylinder bore and seal. Condition 3: Fluid level will decrease with pad wear. Abnormal Conditions Changes in brake pedal feel or travel are indicators that something could be wrong in the brake system. Refer to the symptom chart at Brakes and Traction Control/Testing and Inspection for abnormal condition diagnosis. Bypass Condition Test 1. Disconnect the brake lines at the brake master cylinder. 2. Plug the outlet ports of the brake master cylinder. 3. Apply the brakes. If brake pedal height cannot be maintained, the brake master cylinder has an internal leak and must be rebuilt or replaced. Compensator Port Check The purpose of the compensator ports in the brake master cylinder is to supply any additional brake fluid required by the system due to brake pad wear and to allow brake fluid returning from the brake lines to the brake master cylinder to enter the brake master cylinder reservoir. The returning brake fluid will cause a slight turbulence in the brake master cylinder reservoir. Turbulence seen in the brake master cylinder reservoir upon release of the brake pedal is normal and shows that the compensating ports are not plugged. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Master Cylinder > Component Information > Specifications > Page 5501 Brake Master Cylinder: Adjustments Master Cylinder Push Rod Adjustment 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5639 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5640 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5641 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5642 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5643 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Diagram Information and Instructions > Page 5644 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Page 5645 Generator: Description and Operation The charging system consists of the following components ^ battery ^ generator ^ generator voltage regulator wiring ^ voltage regulator Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Page 5646 Generator: Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Starting and Charging; Charging System; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Generator <--> [Alternator] > Component Information > Diagrams > Page 5647 Generator: Service and Repair REMOVAL 1.

As generator load increases the PCM will adjust idle speed accordingly. This strategy helps reduce idle surges due to switching high current loads. The GLI signal is sent to the PCM from the voltage regulator/generator. The signal is a variable frequency duty cycle. Normal operating frequency is 40 - 250 Hz. Normal signal DC voltage (referenced to ground) is between 1.5 V (low generator load) and 10.5 V (high generator load). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Charging System > Voltage Regulator > Component Information > Service and Repair Voltage Regulator: Service and Repair NOTE: The generator brush and terminal holder and the voltage regulator are installed as an assembly only. 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5719 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5720 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5721 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5722 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5723 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5724 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > Customer Interest for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System - Whining/Buzzing Noise From Speakers Technical Service Bulletin # 02-16-4 Date: 020819 Audio System - Whining/Buzzing Noise From Speakers Article No. 02-16-4 08/19/02 ^ FUEL SYSTEM - FUEL PUMP "WHINING"/"BUZZING" NOISE COMES THROUGH ENTERTAINMENT OR TWO-WAY RADIO SPEAKER ^ RADIO - ENTERTAINMENT OR TWO-WAY COMMUNICATION - "WHINING"/"BUZZING" NOISE IN SPEAKERS CAUSED BY FUEL PUMP ^ NOISE - "WHINING"/"BUZZING" - COMES THROUGH SPEAKERS OF ENTERTAINMENT OR TWO-WAY RADIO FORD: 1990-1994 TEMPO 1990-1997 ESCORT, PROBE, THUNDERBIRD 1990-1998 MUSTANG 1990-1999 TAURUS 1990-2002 CROWN VICTORIA 1997-1999 CONTOUR 2001 TAURUS 1990 BRONCO II 1990-1996 BRONCO 1990-1997 AEROSTAR, F SUPER DUTY, F-250 HD, F-350 1990-1999 F-250 LD 1990-2002 ECONOLINE, F-150, RANGER 1991-2002 EXPLORER 1995-2002 WINDSTAR 1997-2003 EXPEDITION 1999-2002 SUPER DUTY F SERIES 2000-2002 EXCURSION, EXPLORER SPORT TRAC, EXPLORER SPORT 2001-2002 ESCAPE LINCOLN: 1990-1992 MARK VII 1990-1994 CONTINENTAL 1990-2002 TOWN CAR 1998-2003 NAVIGATOR 2002 BLACKWOOD MERCURY: 1990-1994 TOPAZ 1990-1997 COUGAR 1990-1999 SABLE 1990-2002 GRAND MARQUIS 1991-1997 TRACER 1997-1999 MYSTIQUE 2001 SABLE 1993-2002 VILLAGER 1997-2002 MOUNTAINEER TSB 01-7-3 is being republished in its entirety to update the model year coverage and vehicle line coverage. ISSUE A "whining"/"buzzing" noise in the speakers of the entertainment radio or two-way radio on vehicles with an in-tank electric fuel pump may be caused by electrical noise from the fuel pump. ACTION Install an electronic noise Radio Frequency Interference (RFI) Filter (F1PZ-18B925-A) on the fuel pump inside the fuel tank. Refer to the following Test Procedure to confirm that the concern exists, then refer to the Service Procedure for repair details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > Customer Interest for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System - Whining/Buzzing Noise From Speakers > Page 5733 NOTE IF THE VEHICLE HAS AN ELECTRONIC RETURNLESS FUEL SYSTEM, DO NOT INSTALL A RFI FILTER INLINE TO THE FUEL PUMP . ONLY VEHICLES WITH MECHANICAL RETURNLESS FUEL SYSTEMS (PRESSURE REGULATOR IN THE TANK), OR SYSTEMS WITH THE PRESSURE REGULATOR ON THE FUEL RAIL SHOULD BE APPROVED FOR THE RFI FILTER INSTALLATION. NOTE SOME LIGHT TRUCKS REQUIRE ONE (1) RFI FILTER FOR EACH IN-TANK ELECTRIC FUEL PUMP ON MULTI-TANK VEHICLES. NOTE THIS TSB DOES NOT INCLUDE TAURUS FLEXIBLE FUEL VEHICLES (FFVS) OR 1999 RANGER 3.0L FFVS. TEST PROCEDURE Fuel pump radio noise is relatively constant and changes only slightly with vehicle speed. If the frequency of the noise varies or the noise comes and goes with the vehicle speed, then it is not the fuel pump and this fix will not be effective. The following procedure will help determine if the fuel pump is the cause of the radio noise: 1. Turn on the radio before the key is turned on (assuming the radio will operate without the ignition key - you may need to put the ignition key in the Accessory position). 2. Turn the ignition key to the Run position (do not start the engine). 3. The fuel pump should run for about 1 second with the key in the Run position with the engine not running. Listen for noise in the radio. If noise is present while the pump is running and stops when the pump stops, then the noise is being generated by the pump and this procedure should help.

ISSUE A "whining"/"buzzing" noise in the speakers of the entertainment radio or two-way radio on vehicles with an in-tank electric fuel pump may be caused by electrical noise from the fuel pump. ACTION Install an electronic noise Radio Frequency Interference (RFI) Filter (F1PZ-18B925-A) on the fuel pump inside the fuel tank. Refer to the following Test Procedure to confirm that the concern exists, then refer to the Service Procedure for repair details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System - Whining/Buzzing Noise From Speakers > Page 5746 NOTE IF THE VEHICLE HAS AN ELECTRONIC RETURNLESS FUEL SYSTEM, DO NOT INSTALL A RFI FILTER INLINE TO THE FUEL PUMP . ONLY VEHICLES WITH MECHANICAL RETURNLESS FUEL SYSTEMS (PRESSURE REGULATOR IN THE TANK), OR SYSTEMS WITH THE PRESSURE REGULATOR ON THE FUEL RAIL SHOULD BE APPROVED FOR THE RFI FILTER INSTALLATION. NOTE SOME LIGHT TRUCKS REQUIRE ONE (1) RFI FILTER FOR EACH IN-TANK ELECTRIC FUEL PUMP ON MULTI-TANK VEHICLES. NOTE THIS TSB DOES NOT INCLUDE TAURUS FLEXIBLE FUEL VEHICLES (FFVS) OR 1999 RANGER 3.0L FFVS. TEST PROCEDURE Fuel pump radio noise is relatively constant and changes only slightly with vehicle speed. If the frequency of the noise varies or the noise comes and goes with the vehicle speed, then it is not the fuel pump and this fix will not be effective. The following procedure will help determine if the fuel pump is the cause of the radio noise: 1. Turn on the radio before the key is turned on (assuming the radio will operate without the ignition key - you may need to put the ignition key in the Accessory position). 2. Turn the ignition key to the Run position (do not start the engine). 3. The fuel pump should run for about 1 second with the key in the Run position with the engine not running. Listen for noise in the radio. If noise is present while the pump is running and stops when the pump stops, then the noise is being generated by the pump and this procedure should help.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5773 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5774 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5775 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5776 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5777 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5778 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box Fuse: Application and ID Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 5781 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 5782 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 5783 Fuse: Application and ID Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 5784 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 5785 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box Fuse Block: Locations Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 5790 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 5791 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 5792 Fuse Block: Locations Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 5793 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 5794 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions Fuse Block: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5797 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

ISSUE Wire harness repairs are supported through the availability of individual components such as: ^ Wire terminals with machine crimped pigtails ^ Hard shell connectors ^ Dual wall heat shrink tubing ^ Complete, loaded, wiring pigtail kits Some of the available tools and service parts that are helpful when performing wiring harness repairs are: ^ Motorcraft Wiring Pigtail Catalog (see website for more information) ^ Rotunda Wire Splice Tool kit 164-R5903 ^ General Wire Terminal Repair Kit (order through Ford Component Sales) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5951 Information on the pigtail and terminal repair kits can also be accessed by technicians via the P15 web site. To access on PTS: ^ Select the year/model of the vehicle on the P15 home page ^ Select the wiring tab ^ Select the link to the pigtail or terminal repair kit at the top right of screen. Additional service information contained in this TSB detailing wire folding, soldering, and crimping techniques may be helpful. ACTION REPAIR VS REPLACEMENT The approved procedure is to repair wiring harnesses with pigtail kits, wire terminals, or hard shell connectors when available. The only exceptions to this procedure are when: ^ The repair cost exceeds the cost to replace the wiring harness ^ There are no component parts released to service the wiring harness RESTRAINTS RELATED WIRING REPAIRS If restraints connectors or wiring circuits are contained in a stand-alone harness, do not repair them; replace the restraints harness unless directed to repair the circuit by a TSB or other Ford Motor Company publication. If restraints connectors or wiring circuits are contained in the main vehicle wiring harnesses (14401, 14A005, etc.), they should be repaired using the solder and heat-shrink repair procedure specified in this TSB. The General Wire Terminal Repair Kit contains gold plated terminated pigtails (with white insulation) and dual wall heat shrink tubing to perform these repairs. Loaded wiring pigtail kits with gold plated terminals are also available in the parts catalog. Disclaimer Service Tips Refer to applicable model year wiring diagrams for circuit information. Twisted Wire Circuits For "Twisted Wire" circuit repair (Figure 1), the twisting must not be disrupted for more than 2" (51 mm) Twist the repaired wires in the same direction and with the same general twist rate as the original wiring. Reapply the shielding on shielded circuits. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5952 Stagger the repairs to minimize harness diameter and maintain harness length (Figure 2). Any leads that are not going to be used need to be sealed with dual wall heat shrink and stowed (Figure 2). Silicone must not be used. Excess wire from the harness can be folded back on itself to maintain the harness length. Reapply any convolute and tape that was removed to make the repair. For 16 AGW and Smaller Diameter Wire Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5953 1. Strip 1-1/2" (37.2 mm) of insulation from Wire # 1 and 3/4" (19.5 mm) of insulation from Wire # 2, taking care not to nick or cut wire strands (Figure 3). Pull wire straight from stripper. If wire is pulled at an angle, wire strands may be cut off. If more than one (1) strand is cut off during stripping, cut off the end and re-strip. 2. Install heat shrink tubing at least 1" (26 mm) away from one of the stripped ends being spliced. Twist wires together. Solder wires together (Figure 4). NOTE USE ROSIN CORE MILDLY ACTIVATED (RMS) SOLDER. DO NOT USE ACID CORE SOLDER FOR WIRE REPAIR. 3. Bend Wire # 1 back in a straight line for sealing (Figure 4). Inspect solder joint bond. NOTE WAIT FOR SOLDER TO COOL BEFORE MOVING WIRES. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5954 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5955 4. Evenly position heat shrink tubing over wire repair (Figure 5). NOTE OVERLAP TUBING ON BOTH WIRES. 5. Use a shielded heat gun to heat the entire length of the heat shrink tubing until the hot melt appears from both ends of the tubing. Durability of a heat shrink tubing splice is dependent on the hot melt that will appear from both ends of the tube. The hot melt forms an adhesive seal between the wire insulation and the heat shrink tubing, which prevents air and moisture from entering the solder point (Figure 5). For 14 AGW and Larger Diameter Wire (Excluding Restraints Wiring Repairs) 1. Strip 1/4" (6.35 mm) of insulation from pigtail wire end once the wire lengths are sized so repairs can be staggered. Take care not to nick or cut wire strands. Pull wire straight from stripper. If wire is pulled at an angle, wire strands may be cut off. If more than one (1) strand is cut off during stripping, cut off the end and re-strip. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5956 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5957 NOTE THE STRIP LENGTH WILL VARY DEPENDING ON THE BUTT SPLICE AND WIRE IN HARNESS. LONGER STRIP LENGTHS ARE REQUIRED WHEN THE WIRE NEEDS TO BE FOLDED TO MATE WITH THE BUTT SPLICE. REFER TO FIGURE 10 CHART FOR STRIP LENGTHS AND FOLDING TECHNIQUES. 2. Slide heat shrink tubing onto one (1) of the wire ends to be crimped, must be at least 1" (25.4 mm) away from stripped end (Figure 6). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5958 3. Identify the appropriate crimping chamber of the Rotunda 164-R5901 Pro-Crimper (or equivalent) by matching the wire size on the dies with the wire size stamped on the butt splice (Figure 7). Hold the crimping tool so the identified wire sizes are facing you. Squeeze tool handles together until the ratchet releases, then allow the jaws of the tool to open fully. 4. Center one (1) end of the butt splice on the appropriate crimping chamber. If visible, be sure to place the brazed seam of the butt splice toward the indenter (Figure 8). 5. Hold the butt splice in place and squeeze the tool handles together until the ratchet engages sufficiently to hold the butt splice in position (typically one (1) or two (2) clicks). DO NOT deform the butt splice. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Starting and Charging > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 5959 6. Insert stripped wire into the buff splice, making sure the insulation on wire does not enter the butt splice (Figure 8). 7. Holding the wire in place, squeeze tool handles together until ratchet releases. Allow tool handles to open, then remove crimped butt splice. 8. To crimp the other half of the splice, reposition the un-crimped wire barrel in the same crimping chamber, and repeat Steps 3-8. If splice cannot be turned for crimping the other half, turn the tool around. 9. Check for acceptable crimp. a. Crimp should be centered on each end of the butt splice. It is acceptable for crimp to be slightly off center, but not off the end of the buff splice (Figure 9-a). b. Wire insulation does not enter butt splice. Wire is flush with or extends slightly beyond end of buff splice (Figure 9-b). c. Wire is visible through inspection hole of splices (Figure 9-c). 10. Evenly position heat shrink tubing over wire repair (Figure 5). NOTE OVERLAP TUBING ON BOTH WIRES. 11. Use a shielded heat gun to heat the entire length of the heat shrink tubing until the hot melt appears from both ends of the tubing. Durability of a heat shrink tubing splice is dependent on the hot melt that will appear from both ends of the tube. The hot melt forms an adhesive seal between the wire insulation and the heat shrink tubing, which prevents air and moisture from entering the solder point (Figure 5). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5965 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5966 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5967 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5968 Electrical Accessory Panel: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5969 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5970 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5971 Lock Relay Block Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5972 Behind right hand side of instrument panel. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5973 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Locations > Battery Junction Box > Page 5974 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions Electrical Accessory Panel: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5977 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5985 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5986 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5987 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5988 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5989 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electrical Accessory Panel > Component Information > Diagrams > Diagram Information and Instructions > Page 5990 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > Customer Interest for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System Whining/Buzzing Noise From Speakers Technical Service Bulletin # 02-16-4 Date: 020819 Audio System - Whining/Buzzing Noise From Speakers Article No. 02-16-4 08/19/02 ^ FUEL SYSTEM - FUEL PUMP "WHINING"/"BUZZING" NOISE COMES THROUGH ENTERTAINMENT OR TWO-WAY RADIO SPEAKER ^ RADIO - ENTERTAINMENT OR TWO-WAY COMMUNICATION - "WHINING"/"BUZZING" NOISE IN SPEAKERS CAUSED BY FUEL PUMP ^ NOISE - "WHINING"/"BUZZING" - COMES THROUGH SPEAKERS OF ENTERTAINMENT OR TWO-WAY RADIO FORD: 1990-1994 TEMPO 1990-1997 ESCORT, PROBE, THUNDERBIRD 1990-1998 MUSTANG 1990-1999 TAURUS 1990-2002 CROWN VICTORIA 1997-1999 CONTOUR 2001 TAURUS 1990 BRONCO II 1990-1996 BRONCO 1990-1997 AEROSTAR, F SUPER DUTY, F-250 HD, F-350 1990-1999 F-250 LD 1990-2002 ECONOLINE, F-150, RANGER 1991-2002 EXPLORER 1995-2002 WINDSTAR 1997-2003 EXPEDITION 1999-2002 SUPER DUTY F SERIES 2000-2002 EXCURSION, EXPLORER SPORT TRAC, EXPLORER SPORT 2001-2002 ESCAPE LINCOLN: 1990-1992 MARK VII 1990-1994 CONTINENTAL 1990-2002 TOWN CAR 1998-2003 NAVIGATOR 2002 BLACKWOOD MERCURY: 1990-1994 TOPAZ 1990-1997 COUGAR 1990-1999 SABLE 1990-2002 GRAND MARQUIS 1991-1997 TRACER 1997-1999 MYSTIQUE 2001 SABLE 1993-2002 VILLAGER 1997-2002 MOUNTAINEER TSB 01-7-3 is being republished in its entirety to update the model year coverage and vehicle line coverage. ISSUE A "whining"/"buzzing" noise in the speakers of the entertainment radio or two-way radio on vehicles with an in-tank electric fuel pump may be caused by electrical noise from the fuel pump. ACTION Install an electronic noise Radio Frequency Interference (RFI) Filter (F1PZ-18B925-A) on the fuel pump inside the fuel tank. Refer to the following Test Procedure to confirm that the concern exists, then refer to the Service Procedure for repair details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > Customer Interest for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System Whining/Buzzing Noise From Speakers > Page 5999 NOTE IF THE VEHICLE HAS AN ELECTRONIC RETURNLESS FUEL SYSTEM, DO NOT INSTALL A RFI FILTER INLINE TO THE FUEL PUMP . ONLY VEHICLES WITH MECHANICAL RETURNLESS FUEL SYSTEMS (PRESSURE REGULATOR IN THE TANK), OR SYSTEMS WITH THE PRESSURE REGULATOR ON THE FUEL RAIL SHOULD BE APPROVED FOR THE RFI FILTER INSTALLATION. NOTE SOME LIGHT TRUCKS REQUIRE ONE (1) RFI FILTER FOR EACH IN-TANK ELECTRIC FUEL PUMP ON MULTI-TANK VEHICLES. NOTE THIS TSB DOES NOT INCLUDE TAURUS FLEXIBLE FUEL VEHICLES (FFVS) OR 1999 RANGER 3.0L FFVS. TEST PROCEDURE Fuel pump radio noise is relatively constant and changes only slightly with vehicle speed. If the frequency of the noise varies or the noise comes and goes with the vehicle speed, then it is not the fuel pump and this fix will not be effective. The following procedure will help determine if the fuel pump is the cause of the radio noise: 1. Turn on the radio before the key is turned on (assuming the radio will operate without the ignition key - you may need to put the ignition key in the Accessory position). 2. Turn the ignition key to the Run position (do not start the engine). 3. The fuel pump should run for about 1 second with the key in the Run position with the engine not running. Listen for noise in the radio. If noise is present while the pump is running and stops when the pump stops, then the noise is being generated by the pump and this procedure should help.

ISSUE A "whining"/"buzzing" noise in the speakers of the entertainment radio or two-way radio on vehicles with an in-tank electric fuel pump may be caused by electrical noise from the fuel pump. ACTION Install an electronic noise Radio Frequency Interference (RFI) Filter (F1PZ-18B925-A) on the fuel pump inside the fuel tank. Refer to the following Test Procedure to confirm that the concern exists, then refer to the Service Procedure for repair details. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Electronic Noise Suppressor > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Electronic Noise Suppressor: > 02-16-4 > Aug > 02 > Audio System - Whining/Buzzing Noise From Speakers > Page 6012 NOTE IF THE VEHICLE HAS AN ELECTRONIC RETURNLESS FUEL SYSTEM, DO NOT INSTALL A RFI FILTER INLINE TO THE FUEL PUMP . ONLY VEHICLES WITH MECHANICAL RETURNLESS FUEL SYSTEMS (PRESSURE REGULATOR IN THE TANK), OR SYSTEMS WITH THE PRESSURE REGULATOR ON THE FUEL RAIL SHOULD BE APPROVED FOR THE RFI FILTER INSTALLATION. NOTE SOME LIGHT TRUCKS REQUIRE ONE (1) RFI FILTER FOR EACH IN-TANK ELECTRIC FUEL PUMP ON MULTI-TANK VEHICLES. NOTE THIS TSB DOES NOT INCLUDE TAURUS FLEXIBLE FUEL VEHICLES (FFVS) OR 1999 RANGER 3.0L FFVS. TEST PROCEDURE Fuel pump radio noise is relatively constant and changes only slightly with vehicle speed. If the frequency of the noise varies or the noise comes and goes with the vehicle speed, then it is not the fuel pump and this fix will not be effective. The following procedure will help determine if the fuel pump is the cause of the radio noise: 1. Turn on the radio before the key is turned on (assuming the radio will operate without the ignition key - you may need to put the ignition key in the Accessory position). 2. Turn the ignition key to the Run position (do not start the engine). 3. The fuel pump should run for about 1 second with the key in the Run position with the engine not running. Listen for noise in the radio. If noise is present while the pump is running and stops when the pump stops, then the noise is being generated by the pump and this procedure should help.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6039 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6040 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6041 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6042 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6043 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 6044 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box Fuse: Application and ID Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 6047 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 6048 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 6049 Fuse: Application and ID Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 6050 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Application and ID > Battery Junction Box > Page 6051 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box Fuse Block: Locations Battery Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 6056 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 6057 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 6058 Fuse Block: Locations Central Junction Box Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 6059 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Locations > Battery Junction Box > Page 6060 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions Fuse Block: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 6063 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 6071 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 6072 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 6073 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration.

article supersedes TSB 03-11-6 to update the service procedure, vehicle lines and model years. ISSUE Wire harness repairs are supported through the availability of individual components such as: ^ Wire terminals with machine crimped pigtails ^ Hard shell connectors ^ Dual wall heat shrink tubing ^ Complete, loaded, wiring pigtail kits Some of the available tools and service parts that are helpful when performing wiring harness repairs are: ^ Motorcraft Wiring Pigtail Catalog (see website for more information) ^ Rotunda Wire Splice Tool kit 164-R5903 ^ General Wire Terminal Repair Kit (order through Ford Component Sales) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6217 Information on the pigtail and terminal repair kits can also be accessed by technicians via the P15 web site. To access on PTS: ^ Select the year/model of the vehicle on the P15 home page ^ Select the wiring tab ^ Select the link to the pigtail or terminal repair kit at the top right of screen. Additional service information contained in this TSB detailing wire folding, soldering, and crimping techniques may be helpful. ACTION REPAIR VS REPLACEMENT The approved procedure is to repair wiring harnesses with pigtail kits, wire terminals, or hard shell connectors when available. The only exceptions to this procedure are when: ^ The repair cost exceeds the cost to replace the wiring harness ^ There are no component parts released to service the wiring harness RESTRAINTS RELATED WIRING REPAIRS If restraints connectors or wiring circuits are contained in a stand-alone harness, do not repair them; replace the restraints harness unless directed to repair the circuit by a TSB or other Ford Motor Company publication. If restraints connectors or wiring circuits are contained in the main vehicle wiring harnesses (14401, 14A005, etc.), they should be repaired using the solder and heat-shrink repair procedure specified in this TSB. The General Wire Terminal Repair Kit contains gold plated terminated pigtails (with white insulation) and dual wall heat shrink tubing to perform these repairs. Loaded wiring pigtail kits with gold plated terminals are also available in the parts catalog. Disclaimer Service Tips Refer to applicable model year wiring diagrams for circuit information. Twisted Wire Circuits For "Twisted Wire" circuit repair (Figure 1), the twisting must not be disrupted for more than 2" (51 mm) Twist the repaired wires in the same direction and with the same general twist rate as the original wiring. Reapply the shielding on shielded circuits. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6218 Stagger the repairs to minimize harness diameter and maintain harness length (Figure 2). Any leads that are not going to be used need to be sealed with dual wall heat shrink and stowed (Figure 2). Silicone must not be used. Excess wire from the harness can be folded back on itself to maintain the harness length. Reapply any convolute and tape that was removed to make the repair. For 16 AGW and Smaller Diameter Wire Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6219 1. Strip 1-1/2" (37.2 mm) of insulation from Wire # 1 and 3/4" (19.5 mm) of insulation from Wire # 2, taking care not to nick or cut wire strands (Figure 3). Pull wire straight from stripper. If wire is pulled at an angle, wire strands may be cut off. If more than one (1) strand is cut off during stripping, cut off the end and re-strip. 2. Install heat shrink tubing at least 1" (26 mm) away from one of the stripped ends being spliced. Twist wires together. Solder wires together (Figure 4). NOTE USE ROSIN CORE MILDLY ACTIVATED (RMS) SOLDER. DO NOT USE ACID CORE SOLDER FOR WIRE REPAIR. 3. Bend Wire # 1 back in a straight line for sealing (Figure 4). Inspect solder joint bond. NOTE WAIT FOR SOLDER TO COOL BEFORE MOVING WIRES. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6220 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6221 4. Evenly position heat shrink tubing over wire repair (Figure 5). NOTE OVERLAP TUBING ON BOTH WIRES. 5. Use a shielded heat gun to heat the entire length of the heat shrink tubing until the hot melt appears from both ends of the tubing. Durability of a heat shrink tubing splice is dependent on the hot melt that will appear from both ends of the tube. The hot melt forms an adhesive seal between the wire insulation and the heat shrink tubing, which prevents air and moisture from entering the solder point (Figure 5). For 14 AGW and Larger Diameter Wire (Excluding Restraints Wiring Repairs) 1. Strip 1/4" (6.35 mm) of insulation from pigtail wire end once the wire lengths are sized so repairs can be staggered. Take care not to nick or cut wire strands. Pull wire straight from stripper. If wire is pulled at an angle, wire strands may be cut off. If more than one (1) strand is cut off during stripping, cut off the end and re-strip. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6222 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6223 NOTE THE STRIP LENGTH WILL VARY DEPENDING ON THE BUTT SPLICE AND WIRE IN HARNESS. LONGER STRIP LENGTHS ARE REQUIRED WHEN THE WIRE NEEDS TO BE FOLDED TO MATE WITH THE BUTT SPLICE. REFER TO FIGURE 10 CHART FOR STRIP LENGTHS AND FOLDING TECHNIQUES. 2. Slide heat shrink tubing onto one (1) of the wire ends to be crimped, must be at least 1" (25.4 mm) away from stripped end (Figure 6). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6224 3. Identify the appropriate crimping chamber of the Rotunda 164-R5901 Pro-Crimper (or equivalent) by matching the wire size on the dies with the wire size stamped on the butt splice (Figure 7). Hold the crimping tool so the identified wire sizes are facing you. Squeeze tool handles together until the ratchet releases, then allow the jaws of the tool to open fully. 4. Center one (1) end of the butt splice on the appropriate crimping chamber. If visible, be sure to place the brazed seam of the butt splice toward the indenter (Figure 8). 5. Hold the butt splice in place and squeeze the tool handles together until the ratchet engages sufficiently to hold the butt splice in position (typically one (1) or two (2) clicks). DO NOT deform the butt splice. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Power and Ground Distribution > Wiring Harness > Component Information > Technical Service Bulletins > Electrical - Wiring Soldering/Crimping Service Tips > Page 6225 6. Insert stripped wire into the buff splice, making sure the insulation on wire does not enter the butt splice (Figure 8). 7. Holding the wire in place, squeeze tool handles together until ratchet releases. Allow tool handles to open, then remove crimped butt splice. 8. To crimp the other half of the splice, reposition the un-crimped wire barrel in the same crimping chamber, and repeat Steps 3-8. If splice cannot be turned for crimping the other half, turn the tool around. 9. Check for acceptable crimp. a. Crimp should be centered on each end of the butt splice. It is acceptable for crimp to be slightly off center, but not off the end of the buff splice (Figure 9-a). b. Wire insulation does not enter butt splice. Wire is flush with or extends slightly beyond end of buff splice (Figure 9-b). c. Wire is visible through inspection hole of splices (Figure 9-c). 10. Evenly position heat shrink tubing over wire repair (Figure 5). NOTE OVERLAP TUBING ON BOTH WIRES. 11. Use a shielded heat gun to heat the entire length of the heat shrink tubing until the hot melt appears from both ends of the tubing. Durability of a heat shrink tubing splice is dependent on the hot melt that will appear from both ends of the tube. The hot melt forms an adhesive seal between the wire insulation and the heat shrink tubing, which prevents air and moisture from entering the solder point (Figure 5). Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Specifications > Alignment Specifications Alignment: Specifications Alignment Specifications General Alignment Specifications General Alignment Specifications General Alignment Specifications General Alignment Specifications Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Specifications > Alignment Specifications > Page 6231 Alignment: Specifications Ride Height Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Specifications > Alignment Specifications > Page 6232 Alignment: Specifications Torque Specifications Front Suspension Upper Arm Nuts .......................................................................................................................................... 113-153 Nm (84-112 ft. lbs.)

Toe is adjusted by the use of the front wheel spindle tie rod adjusting sleeve. The three basic alignment angles are camber, caster, and toe. Camber and toe affect tire wear and directional stability, caster affects directional stability only. Camber, caster and toe settings change when the vehicle is loaded. The specifications given are static settings with the vehicle unloaded. Camber is the inward or outward tilting of the wheels at the top. When the wheels tilt out at the top the camber is positive (+). When the wheels tilt in at the top the camber is negative (-). The amount of camber is measured in degrees from vertical. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Specifications > Page 6235 Steering axis inclination (included angle) is the center line drawn through the ball joints when viewed from the front. Caster is the tilting of the steering axis either forward or backward from vertical. A backward tilt is positive (+) and a forward tilt is negative Wheel Track Toe is a measurement of how much the front of the wheels are turned in or out from the straight-ahead position. When the wheels are turned in, toe is positive (+)(toe in). When the wheels are turned out, toe is negative (-)(toe out). Toe is measured in degrees, from side to side and totaled. Toe should only be checked and adjusted after the camber and caster have been set to the proper specifications. Dogtracking Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Specifications > Page 6236 By design the vehicle has a front track that is wider at the front than the rear. Front track is the distance between the two front tires; rear track is the distance between the two rear tires. Dogtracking is the condition where the rear axle is not square to the chassis. Heavily crowned roads may give the illusion of dogtracking. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Service and Repair > Camber and Caster Adjustment Alignment: Service and Repair Camber and Caster Adjustment 1. Remove the alignment plate. 1. Remove the upper suspension arm nuts. 2. Remove the alignment plate. 2. Install the washers and the adjusting nuts. 3. Note: A pry bar can be used between the front suspension upper arm and the frame pocket to aid in moving the arm. To increase caster and camber, use the following steps. 1. To increase caster move the front of the front suspension upper arm outboard and move the rear of the front suspension upper arm inboard. 2. To increase camber, move the front suspension upper arm outboard equally. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Service and Repair > Camber and Caster Adjustment > Page 6239 4. To decrease caster and camber, use the following steps. 1. To decrease caster, move the front of the front suspension upper arm inboard and move the rear of the front suspension upper arm outboard. 2. To decrease camber, move the front suspension upper arm inboard equally. 5. Note: Each increment of the notches on the frame pocket represents 0.4 degree. Set the caster and camber to specifications. If a caster increase of 1.2 degrees is required, move the front of the front suspension upper arm outboard by 3 notches and move the rear of the front suspension upper arm inboard by 3 notches, since one notch represents 0.4 degree. 6. Tighten the upper suspension arm nuts. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Alignment > System Information > Service and Repair > Camber and Caster Adjustment > Page 6240 Alignment: Service and Repair Toe Adjustment 1.

There may be a misunderstanding about how much Idler Arm movement/play is acceptable - because there is no movement/free-play specification published in the Workshop Manual or any other dealer Service Information documents. ACTION Use proper inspection practices referred to in the following Service Procedure for measuring Idler Arm freeplay. The maximum allowable freeplay is 5 mm (0.200"). Refer to the following Service Procedure for the correct Idler Arm inspection details. SERVICE PROCEDURE 1. Place the vehicle on a drive-on hoist. 2. Obtain a dial indicator and holding fixture similar to that referenced in the Figures shown (a magnetic-base dial indicator is also acceptable - provided it mounts securely). 3. Clean off the area on the Center Link next to the Idler Arm mount. 4. Install and zero-out the dial indicator on the Center Link. 5. While grasping the Center Link, and attempting to move it up and down; observe the dial indicator reading. 6. If the reading is 5 mm (0.200") or less, the Idler Arm movement is acceptable, and the Idler Arm should not be replaced. 7. If the reading is greater than 5 mm (0.200"), replace the Idler Arm. 8. Check and adjust toe-in as necessary if the Idler Arm is replaced. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Steering > Idler Arm > Component Information > Technical Service Bulletins > Idler Arm - Replacement Specifications > Page 6305 ^ Figure # 1 shows one type of tool in position on a 4X4 vehicle ^ Figure # 2 shows the tip of the dial indicator resting on the Center Link adjacent to the Idler Arm attachment point ^ Figure # 3 shows one type of tool in position on a 4X2 vehicle Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Steering > Idler Arm > Component Information > Technical Service Bulletins > Idler Arm - Replacement Specifications > Page 6306 OTHER APPLICABLE ARTICLES: NONE WARRANTY STATUS: Eligible Under The Provisions Of Bumper To Bumper Warranty Coverage OPERATION DESCRIPTION TIME 020401A Measure Idler Arm 0.2 Hr.

This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. 1. Turn all vehicle accessories OFF. 2. Turn the ignition switch to OFF. 3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 5. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. The side impact sensors (if equipped) are located at or near the base of the B-pillars. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). 6. Disconnect the battery ground cable (14301) and wait at least one minute. Repowering Procedure Warning: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards. 1. Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected. 2. Turn the ignition switch from OFF to ON. 3. Install the RCM fuse F22 (10A) to the CJB and close the cover. Warning: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected. 4. Connect the battery ground cable. 5. Prove out the supplemental restraint system (SRS) as follows: Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either: fail to light. - remain lit continuously. - flash. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Steering > Steering Column > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 6388 The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON.

ISSUE This article is to be used as an updated procedure for inspecting tie rod end wear. ACTION This procedure is designed to supplement the Workshop Manual, as it provides a more detailed tie rod end inspection procedure. SERVICE INFORMATION NOTE FOR ESCAPE VEHICLES, THIS TIE ROD END INSPECTION PROCEDURE SHOULD ONLY BE COMPLETED ON THE OUTER TIE RODS. FOR ESCAPE INNER TIE ROD INSPECTION PROCEDURES, REFER TO WORKSHOP MANUAL SECTION 211-00. Step 1 - Free Play: Check the outer tie rod ends by grasping by hand and push up and down. Check the inner tie rod ends, pushing them front to rear. If any free play is observed in a joint, it is worn and should be replaced. Step 2 - Stud Lash - Free Play: While vehicle is on the ground or on a drive-on hoist, have an assistant rotate the steering wheel rapidly back and forth from 10 o'clock to 2 o'clock to 10 o'clock while observing the inner and outer tie rods. If the outer tie rod ends have any vertical movement or the inner tie rod ends have any horizontal movement, the tie rod end with the observed movement should be replaced. Step 3 - Seal Inspection: Raise the vehicle on a hoist and remove the front wheels. The wheels will need to be turned to the right in order to inspect the passenger side inner tie rod end and to the left to inspect the drivers side inner tie rod end. Inspect all four seals for tears, perforations and wear. If there is any indication of wear or perforations on the seal, that tie rod end should be replaced. Step 4 - Stud Corrosion: For Escape Vehicles - If Squeak is noticed during Step 2, disconnect tie rod from knuckle and articulate stud in socket. If squeak is verified, replace part. While pushing down on seal, at stud end, if corrosion present at contact point at base of stud, replace part. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Steering > Tie Rod > Tie Rod End > Component Information > Technical Service Bulletins > Steering - Tie Rod End Inspection Procedures > Page 6451 For All Other Vehicles Covered In This Article: Using a wrench, rotate the tie rod end so that the front of the seal on the outer tie rod end is expanded (Figure 1). Using a puffy knife or other hard, flat, dull object, lift the bottom of the seal up, exposing the stud (Figure 2). If any water escapes from the seal in the form of bubbles or in a liquid form, that tie rod end should be replaced. Closely examine the stud for signs of corrosion, especially around the interface with the knuckle. A rag might be needed to clean off any grease on the stud that impairs a good visual inspection. If there is any sign of corrosion, that tie rod end should be replaced. Rotate the tie rod end in the opposite direction to expand the inner tie rod seal. Repeat the inspection procedure used on the outer tie rod. Repeat this entire procedure on the other side of the vehicle. If there is sign of corrosion, that tie rod end should be replaced. NOTE IF ANY TIE ROD ENDS ARE REMOVED, INSPECT THE SEAL AND THE STUD AGAIN NOTING ANY DIFFERENCES IN VISUAL PERCEPTIONS FROM WHEN THE PART WAS ON THE VEHICLE. CHECKING THE STUD AFTER REMOVAL HELPS IMPROVE CONSCIOUSNESS OF ISSUES WHEN INSPECTING PARTS ON VEHICLE.

ISSUE Some 1997-2002 Expedition 4X4 and 1998-2002 Navigator 4X4 vehicles equipped with 4-wheel air suspension, may exhibit repeat air compressor drier failures. The drier cap may become detached from the drier body, or the drier body may be broken at the neck near the compressor head. This may be due to incomplete or incorrect system diagnosis that leads to replacement of only the original air suspension compressor, despite the fact that the compressor is not the root cause of the concern. Compressor failure in these instances is only a symptom of an underlying system problem. ACTION Refer to the service information contained in this TSB for information on proper diagnosis of system issues. Be sure to check the system for proper pneumatic function as described during service to ensure a robust repair. SERVICE INFORMATION Overview Proper pneumatic function can be tested by verifying that both the front AND the rear of the vehicle can be raised and lowered one inch using a scan tool, and by monitoring the height sensor PIDs for movement while the vehicle is in the service bay. If the vehicle does not raise and lower normally, check the solenoid valves and air lines for blockages and/or restrictions. Replace any blocked or restricted solenoids and air lines. ALWAYS check for proper pneumatic function before returning the vehicle back to the customer. NOTE DISCONNECTING AN AIR LINE THAT IS CONNECTED TO THE AIR COMPRESSOR CAN CAUSE PERSONAL INJURY OR DAMAGE TO COMPONENTS AS HIGH PRESSURE IS VENTED UNCONTROLLED. If diagnostics lead to compressor/dryer assembly replacement, use the following service procedure to insure complete and thorough service. 1. Using the New Generation STAR (NGS) tester, vent the compressor/drier assembly. 2. Using regulated shop air, blow out the air lines from the drier to the front fill solenoid valve and from the drier to the rear fill solenoid valve, before installing the new compressor assembly. 3. Replace the air suspension compressor assembly. Refer to Workshop Manual Section 204-05 for compressor installation instructions. 4. Replace the front fill solenoid. Refer to Workshop Manual Section 204-05 for replacement instructions. The front fill solenoid must be replaced because in these cases, it may have sustained damage from the drier desiccant or other contaminants. 5. Connect the New Generation STAR (NGS) tester to the vehicle while the vehicle is parked in the service bay with the engine running. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Suspension > Suspension Control ( Automatic - Electronic ) > Air Dryer, Suspension Control > Component Information > Technical Service Bulletins > Air Suspension - Repeat Compressor Drier Failures > Page 6552 6. Install a pressure gauge capable of reading 400 PSI at the front air line (Figure 1). Using the scan tool, command the compressor ON. Check the output of the compressor on the gauge: a. If the compressor does not output at least 110 PSI within 30 seconds, replace the compressor again and retest. NOTE VERIFY THAT THE SUSPENSION RAISES PROPERLY. 7. Using the scan tool, command the front of the vehicle to raise up one inch. The front suspension should rise one inch in 25 seconds or less. a. If the compressor output is near 300 PSI, check4or air line or solenoid restrictions, repair as necessary and retest. Otherwise, proceed to Step 7b. NOTE SUSPENSION UPWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD DECREASE BY .35 TO .45 VOLTS. b. If the front of the vehicle DOES NOT raise, check the front pneumatic system for leaks, inoperable or blocked solenoid valves or pinched air lines. If an issue is found, repair as required and repeat Step 7 to verify proper operation. c. If no problem found, continue to Step 8. NOTE VERIFY THAT SUSPENSION PROPERLY. 8. If the front of the vehicle DOES raise, use the scan tool to command the front of the vehicle to lower one inch. The front suspension should lower one inch in 20 seconds or less. NOTE SUSPENSION DOWNWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD INCREASE BY .35 TO .45 VOLTS. a. If the front of the vehicle DOES NOT lower, check the front pneumatic system for leaks, inoperable or blocked solenoid valves, an inoperable vent solenoid, or pinched air lines. Repair air lines or replace solenoid valves as required. 9. Repeat Steps 7 and 8 for the rear. Command the rear of the vehicle, and monitor the rear height sensor PID. Voltages should increase when the vehicle is lowered, and decrease when the vehicle is raised. If the rear of the vehicle does not raise and lower as commanded, inspect the rear pneumatic system for leaks, inoperable or blocked solenoid valves, an inoperable vent solenoid, or pinched air lines, and repair as necessary. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Suspension > Suspension Control ( Automatic - Electronic ) > Air Dryer, Suspension Control > Component Information > Technical Service Bulletins > Air Suspension - Repeat Compressor Drier Failures > Page 6553 10.

If the vehicle does not raise and lower normally, check the solenoid valves and air lines for blockages and/or restrictions. Replace any blocked or restricted solenoids and air lines. ALWAYS check for proper pneumatic function before returning the vehicle back to the customer. NOTE DISCONNECTING AN AIR LINE THAT IS CONNECTED TO THE AIR COMPRESSOR CAN CAUSE PERSONAL INJURY OR DAMAGE TO COMPONENTS AS HIGH PRESSURE IS VENTED UNCONTROLLED. If diagnostics lead to compressor/dryer assembly replacement, use the following service procedure to insure complete and thorough service. 1. Using the New Generation STAR (NGS) tester, vent the compressor/drier assembly. 2. Using regulated shop air, blow out the air lines from the drier to the front fill solenoid valve and from the drier to the rear fill solenoid valve, before installing the new compressor assembly. 3. Replace the air suspension compressor assembly. Refer to Workshop Manual Section 204-05 for compressor installation instructions. 4. Replace the front fill solenoid. Refer to Workshop Manual Section 204-05 for replacement instructions. The front fill solenoid must be replaced because in these cases, it may have sustained damage from the drier desiccant or other contaminants. 5. Connect the New Generation STAR (NGS) tester to the vehicle while the vehicle is parked in the service bay with the engine running. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Suspension > Suspension Control ( Automatic - Electronic ) > Compressor/Pump, Suspension Control > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Compressor/Pump: > 03-9-2 > May > 03 > Air Suspension - Repeat Compressor Drier Failures > Page 6590 6.

If the compressor does not output at least 110 PSI within 30 seconds, replace the compressor again and retest. NOTE VERIFY THAT THE SUSPENSION RAISES PROPERLY. 7. Using the scan tool, command the front of the vehicle to raise up one inch. The front suspension should rise one inch in 25 seconds or less. a. If the compressor output is near 300 PSI, check4or air line or solenoid restrictions, repair as necessary and retest. Otherwise, proceed to Step 7b. NOTE SUSPENSION UPWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD DECREASE BY .35 TO .45 VOLTS. b. If the front of the vehicle DOES NOT raise, check the front pneumatic system for leaks, inoperable or blocked solenoid valves or pinched air lines. If an issue is found, repair as required and repeat Step 7 to verify proper operation. c. If no problem found, continue to Step 8. NOTE VERIFY THAT SUSPENSION PROPERLY. 8. If the front of the vehicle DOES raise, use the scan tool to command the front of the vehicle to lower one inch. The front suspension should lower one inch in 20 seconds or less. NOTE SUSPENSION DOWNWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD INCREASE BY .35 TO .45 VOLTS. a. If the front of the vehicle DOES NOT lower, check the front pneumatic system for leaks, inoperable or blocked solenoid valves, an inoperable vent solenoid, or pinched air lines. Repair air lines or replace solenoid valves as required. 9. Repeat Steps 7 and 8 for the rear. Command the rear of the vehicle, and monitor the rear height sensor PID. Voltages should increase when the vehicle is lowered, and decrease when the vehicle is raised.

Do not attempt to open, puncture, or apply heat to the shock absorbers. All vehicles are equipped with low pressure gas-filled hydraulic shock absorbers of the direct acting type. They are non-adjustable and non-refillable. They cannot be serviced as cartridges and must be serviced as shock assemblies. Before replacing a shock absorber, check the action of the shock absorbers as follows. Vehicle Inspection 1. Check all tires for proper inflation pressure. 2. Check tire condition to confirm proper front end alignment, tire balance and overall tire condition such as separation or bulges. 3. Check the vehicle for optional suspension equipment such as heavy-duty handling or trailer tow suspensions. These suspensions will have a firmer feeling ride than standard suspensions. 4. Check the vehicle attitude for evidence of possible overload or sagging. Many times, front springs and front shock absorbers are replaced in an effort to solve a vehicle sag concern. Shock absorbers are, by design, hydraulic damping units only and unlike suspension springs, do not support any suspension loads. Therefore, replacing a shock absorber will not correct a vehicle sag concern. 5. Road test the vehicle to confirm the customer concern. 6. Make sure the shock absorber is securely and properly installed. 7. Check the shock absorber insulators for damage and wear. 8. Replace any worn or damaged insulators and tighten attachments to the specified torque (on a shock absorber which incorporates internal insulators, replace the shock absorbers). 9. Tighten the shock absorber attachments to the specified torque. 10. Inspect the shock absorber for evidence of fluid leakage. Leakage is a condition in which the entire shock body is covered with oil, and the oil will drip from the shock onto the pavement. A light film of oil (weepage) on the upper portion of the front shock absorber is permissible and is a result of proper shock lubrication. Weepage is a condition in which a thin film of oil may be deposited on the shock outer tube (body) and is normally noticed due to the collection of dust in this area. Front shock absorbers which exhibit this weepage condition are functional units and should not be replaced. 11. If leakage exists: - Make sure the fluid observed is not from sources other than the front shock absorber. - Replace the worn or damaged front shock absorber. 12. Disconnect the lower end of the shock absorber. 13. Extend and compress the shock absorber as fast as possible, using as much travel as possible. Action should become smooth and uniform throughout each stroke. Higher resistance on extension than on compression is a normal condition. - Faint swish noises are also normal. Hoist Check WARNING: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the RH kick panel area. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. 1. Noise: Check for loose/damaged suspension or shock attachments when locating a noise symptom, Verify that all the attachments or the suspension components and the front springs and front shock absorbers arc in good condition and tight. Replace any worn or damaged parts or components. 2. Bottom/Hopping: Check the condition of the rubber suspension travel stops ( front suspension bumpers). Examine them for evidence of previous overload or damaged components; replace them if they are worn or missing. 3. Force-Check: Support the front axle and remove the lower front shock attachment. Stroke the front shock body using as much travel as possible. The action should be smooth and uniform throughout each stroke. Damping forces should be equivalent on both sides of the vehicle. 4. Replace only the worn or damaged front shock absorber. In the past, it was recommended that front shock absorbers be replaced in pairs if one unit became unserviceable. Improved sealing, new materials, design, and improved rod machining and hardening techniques have added to the reliability of shock absorbers. Therefore, front shock absorbers no longer need to be replaced in pairs when only one unit is not serviceable. Bench Test The front shock absorbers are gas-pressurized, which results in their being fully extended when not restrained. If a front shock absorber does not fully extend, it is damaged and should be replaced. With the front shock absorber in the normal upright position, compress it and allow it to extend three times to purge the pressure chamber of any gas that may have been introduced during handling. Place the front shock absorber right side up in a vise. Hand-stroke the front shock absorber as fast as possible using as much travel as possible. Action should be smooth and uniform throughout each stroke. Higher resistance on extension than on compression is normal. The following conditions are abnormal: A lag or skip at a reversal of travel near mid-stroke when the front shock absorber is properly primed and in the installed position. - Seizing. - Noise, other than a faint swish, such as a clicking upon fast stroke reversal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Suspension > Suspension Strut / Shock Absorber > Component Information > Specifications > Page 6664 - Excessive fluid leakage. - With rod fully extended, any lateral motion of rod in relation to outer cylinder. If front shock absorber action remains erratic after purging air, install a front shock absorber, replacing only the damaged front shock absorber. Front shock absorbers do not need to be replaced in pairs. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Suspension > Suspension Strut / Shock Absorber > Component Information > Service and Repair > Rear Suspension Strut / Shock Absorber: Service and Repair Rear Removal 1.

This bulletin is authored and endorsed by Hunter, Michelin, Goodyear, Continental/General, Hankook, Bridgestone/Firestone and Pirelli. Items addressed are software upgrades, road test (exercise tires), assembly center verification and warranty restrictions. This type of equipment can be a valuable tool to improve customer satisfaction when used as a vibration repair tool. This type of equipment can also provide a high level of customer satisfaction when used as an assembly too! when the customer has purchased new wheels/tires in the "Around-the-Wheel" program. ACTION The Hunter GSP9700/9712 road force measurement tool is NOT to be used for determining if a tire or wheel meets a specification. It can be used as a service diagnostic tool to minimize road force variation of the tire/wheel assembly. The tool such as the Hunter GSP97OO can approximate the low point of the "'1heel and the high point of the tire. This allows the tire to be matched mounted to the wheel for lowest tire/wheel assembly road force variation. This will minimize the contribution to vibration from the tire/wheel assembly.

The wheel resting on the ground could cause the vehicle to move. - The tire and wheel must always be correctly matched. It is very important to determine the size of each component before any assembly operations commence. Do not mount a 16-inch tire on a 16.5-inch wheel. Failure to adhere to these instructions can result in an explosive separation and cause serious bodily injury or death. Do not mount a 16.5-inch tire on a 16-inch wheel. The tire can come off without warning. - Aftermarket aerosol tire sealants are extremely flammable. Always question the customer to make sure these products have not been used. - Use only wheels and wheel nuts that have been designed for current model year ford trucks. Aftermarket wheels or wheel nuts may not fit or function correctly, and can cause personal injury or damage the vehicle. - Always wear safety goggles or a face shield when performing any work with tire and wheel assemblies. - Retighten the wheel nuts at 800 km (500 miles) after any wheel change or any time the wheel nuts are loosened. - Failure to retighten wheel nuts at the mileage specified can allow wheels to come off while the vehicle is in motion, possibly causing loss of vehicle control and collision. CAUTION: Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong detergents. Use Custom Bright Metal Cleaner .8A-19522-A or equivalent meeting Ford specification ESR-M5B194-B. - Reduce the air pressure as much as possible by pushing the valve core plunger in prior to removing the valve core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Technical Service Bulletins > Page 6711 Wheels: Description and Operation WARNING: Do not mix different types of tires, such as radial, bias, or bias-belted, on the same vehicle except in emergencies (temporary spare usage). Vehicle handling can be seriously affected and can result in loss of control. Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures. Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear. Replacement tires should follow the recommended: tire sizes. - speed rating. - load range. - radial construction type. Use of any other tire size or type may seriously affect: ride. - handling. - speedometer/odometer calibration. - vehicle ground clearance. - tire clearance between the body and chassis. - Wheel bearing life. - brake cooling. New wheels need to be installed when: bent. - dented. - heavily rusted. - leaking. - they have elongated wheel hub bolt holes. - they have excessive lateral or radial runout. The Expedition uses a two-piece wheel nut, containing the nut and a washer. Wheel and tire assemblies are attached by five noncentering wheel nuts. When balancing wheels and tires, use T-type balancing weights. The spare tire is mounted under the frame. The valve stem should. be on the top side of the tire to reduce the possibility of accidental valve stem air leakage. To equalize tire wear, rotate the tires periodically. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Service and Repair > Wheel and Tire Wheels: Service and Repair Wheel and Tire Removal 1.

The suction accumulator is mounted to the A/C accumulator bracket to the right of the vehicle centerline. The inlet tube of the suction accumulator attaches directly to the A/C evaporator core outlet tube and the outlet tube of the suction accumulator attaches to the A/C manifold and tube. After entering the inlet of the suction accumulator, heavier oil-laden refrigerant contacts an internally mounted dome (which serves as an umbrella) and drips down onto the bottom of the canister. ^ A small diameter oil bleed hole, in the bottom of the vapor return tube, allows the accumulated heavier liquid refrigerant and oil mixture to re-enter the compressor suction line at a controlled rate. ^ As the heavier mixture passes through the small diameter liquid bleed hole, it has a second chance to vaporize and recirculate through the A/C compressor without causing compressor damage due to slugging. ^ A fine mesh screened filter fits tightly around the bottom of the vapor return tube to filter out refrigerant system contaminant particles. ^ A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system. ^ A fitting located on the top of the suction accumulator is used to attach the A/C cycling switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C cycling switch can be removed without discharging the A/C system. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Accumulator HVAC > Component Information > Specifications > Page 6755 Accumulator HVAC: Service and Repair REMOVAL 1.

The FS-10 A/C compressor is serviced only as an assembly. The A/C clutch, A/C clutch pulley, A/C clutch field coil and the shaft seal are serviceable. ^ Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator. The FS-10 A/C compressor has the following characteristics: ^ A ten-cylinder swashplate design utilizing the tangential design mount. ^ Displacement of 170 cc (10.4 cubic inches). ^ A one-piece lip-type seal (installed from the front of the A/C compressor) is used to seal it at the shaft opening in the assembly. ^ Five double-acting pistons operate within the cylinder assembly. The pistons are actuated by a swashplate that changes the rotating action of the shaft to a reciprocating force. ^ Reed-type discharge valves are located between the cylinder assembly and the head at each end of the A/C compressor. ^ The A/C compressor uses PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C), or equivalent, meeting Ford specification WSH-M1C231-B. This oil contains special additives required for the A/C compressor. ^ The A/C compressor oil from vehicles equipped with an FS-10 A/C compressor may have a dark color while maintaining a normal oil viscosity. This is normal for this A/C compressor because carbon from the piston rings will discolor the oil. Compressor Clutch Components The magnetic A/C clutch has the following characteristics: ^ It drives the compressor shaft. ^ When battery positive voltage (B+) is applied to the A/C clutch field coil, the clutch disc and hub assembly is drawn toward the A/C clutch pulley. ^ The magnetic force locks the clutch disc and hub assembly and the A/C clutch pulley together as one unit, causing the compressor shaft to rotate. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 6899 ^ When B+ is removed from the A/C clutch field coil, springs in the clutch disc and hub assembly move the clutch plate away from the A/C clutch pulley. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 6900 Compressor Clutch: Adjustments 1.

Discharge and recover the refrigerant; refer to Discharging and Recovery. See: Service and Repair/Refrigerant Discharging and Recovery procedure 2. Disconnect the suspect A/C evaporator core or A/C condenser core from the A/C system. NOTE: DO NOT leak test an A/C evaporator core with the suction accumulator/drier attached to the core tubes. 3. Clean the spring lock couplings. For additional information, refer to Spring Lock Coupling. See: Coupler HVAC/Service and Repair/Spring Lock Coupling Connect and Disconnect Procedure 4. Connect the appropriate test fittings from the A/C test fitting set to the evaporator or condenser tube connections. 5. Connect the red and blue hoses from the manifold gauge set to the test fittings on the A/C evaporator core or A/C condenser core. Connect the yellow hose to a known good vacuum pump. NOTE: The automatic shut-off valves on some gauge set hoses do not open when connected to the test fittings. If available, use hoses without shut-off valves. If hoses with shut-off valves are used, make sure the valve opens when attached to the test fittings or install an adapter which will activate the valve. The test is not valid if the shut-off valve does not open. 6. Open both gauge set valves and start the vacuum pump. Allow the vacuum pump to operate for a minimum of 45 minutes after the gauge set low pressure gauge indicates 101 kPa (30 in-Hg). The 45 minute evacuation is necessary to remove any refrigerant from oil left in the A/C evaporator core or A/C condenser core. If the refrigerant is not completely removed from the oil, outgassing will degrade the vacuum and appear as a refrigerant leak. 7. If the low pressure gauge reading will not drop to 101 kPa (30 in-Hg) when the valves on the gauge and manifold set are open and the vacuum pump is operating, close the gauge set valves and observe the low pressure gauge. If the pressure rises rapidly to zero, a large leak is indicated. Recheck the test fitting connections and gauge set connections before installing a new A/C evaporator core or A/C condenser core. 8. After evacuating for 45 minutes, close the gauge set valves and stop the vacuum pump. Observe the low pressure gauge; it should remain at the 101 kPa (30 in-Hg) mark. ^ If the low pressure gauge reading rises 34 or more kPa (10 or more in-Hg) of vacuum from the 101 kPa (30 in-Hg) position in 10 minutes, a leak is indicated. ^ If a small leak is suspected, wait 30 minutes and observe the vacuum gauge. ^ If a small amount of vacuum is lost, operate the vacuum pump with gauge valves open for an additional 30 minutes to remove any remaining refrigerant from the oil in the A/C evaporator core or A/C condenser core. Then recheck for loss of vacuum. ^ If a very small leak is suspected, allow the system to set overnight with vacuum applied and check for vacuum loss. 9. If the A/C evaporator core or A/C condenser core does leak, as verified by the above procedure, install a new A/C evaporator core or A/C condenser core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Condenser HVAC > Component Information > Specifications > Page 6936 Condenser HVAC: Service and Repair REMOVAL NOTE: ^ Replacement of the suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator. ^ If an A/C condenser core leak is suspected, the A/C condenser core must be leak tested before it is removed from the vehicle. 1.

The A/C blower motor speed control is controlled by switching the control signal voltage of 5 volts OFF and ON 2,000 times per second. By varying the ratio of time on (+5 volts) to time off (0 volts), the EATC module tells the A/C blower motor speed control how fast the blower motor should run. The A/C blower motor speed control has the following features: ^ Has circuitry to protect the blower motor from burning out in the event of a locked rotor condition. ^ Can compensate for changes in battery positive voltage (B+) which prevents the blower speed from slowing down when the engine is idling and will provide up to a maximum of 30 amperes for blower motor operation with battery voltages between 10 and 16 volts. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Control Module HVAC > Component Information > Diagrams > Page 6974 Control Module HVAC: Service and Repair REMOVAL 1.

They can cause axial scratches across the O-ring seal grooves resulting in refrigerant leaks. ^ Do not use a screwdriver or similar tool to remove the A/C tube lock coupling spring; this can cause axial scratches across the O-ring seal grooves resulting in refrigerant leaks. ^ Maintain low speed drill rotation when inserting or removing the cleaning tool to prevent axial scratches which may cause future leaks. ^ Use only new green O-ring seals. The use of any O-ring seals other than specified may result in intermittent leakage during vehicle operation. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Coupler HVAC > Component Information > Diagrams > Page 6982 Coupler HVAC: Description and Operation Spring Lock Coupling The spring lock coupling is a refrigerant line coupling held together by a garter spring inside a circular cage. ^ When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting. ^ The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage. ^ Three O-ring seals are used to seal between the two halves of the A/C condenser core couplings, all other couplings have two O-ring seals. ^ These O-ring seals are green in color and are made of special material. ^ Use only the green O-ring seals listed in the Ford Master Parts Catalog for the spring lock coupling. ^ A plastic indicator ring is used on the spring lock couplings of the A/C evaporator core to indicate, during vehicle assembly, that the coupling is connected. Once the coupling is connected, the indicator ring is no longer necessary but will remain captive by the coupling near the cage opening. ^ The indicator ring may also be used during service operations to indicate connection of the coupling. ^ An A/C tube lock coupling clip may be used to secure the coupling but is not required. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Coupler HVAC > Component Information > Service and Repair > Spring Lock Coupling Connect and Disconnect Procedure Coupler HVAC: Service and Repair Spring Lock Coupling Connect and Disconnect Procedure Spring Lock Coupling SPECIAL SERVICE TOOL(S) DISCONNECT 1.

The A/C evaporator core is the plate/fin type with a unique refrigerant flow path. ^ A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube and is routed so it flows through the partitioned first three plate/fin sections. ^ The next four plate/fin sections are partitioned to force the refrigerant to flow toward the other end of the A/C evaporator core. ^ Refrigerant then continues over to the remaining five plate/fin sections and then moves out of the A/C evaporator core through the A/C evaporator core outlet tube. ^ This S-pass flow pattern accelerates the flow of refrigerant and oil through the A/C evaporator core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Description and Operation > Main Climate Control > Page 7023 Evaporator Core: Description and Operation Auxiliary Climate Control The auxiliary A/C system uses a rear A/C evaporator core which operates in the same manner as the front A/C evaporator core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Description and Operation > Page 7024 Evaporator Core: Testing and Inspection ON-VEHICLE LEAK TEST 1. Discharge and recover the refrigerant; refer to Discharging and Recovery. See: Service and Repair/Refrigerant Discharging and Recovery procedure 2. Disconnect the suspect A/C evaporator core or A/C condenser core from the A/C system. NOTE: DO NOT leak test an A/C evaporator core with the suction accumulator/drier attached to the core tubes. 3. Clean the spring lock couplings. For additional information, refer to Spring Lock Coupling. See: Coupler HVAC/Service and Repair/Spring Lock Coupling Connect and Disconnect Procedure 4. Connect the appropriate test fittings from the A/C test fitting set to the evaporator or condenser tube connections. 5. Connect the red and blue hoses from the manifold gauge set to the test fittings on the A/C evaporator core or A/C condenser core. Connect the yellow hose to a known good vacuum pump. NOTE: The automatic shut-off valves on some gauge set hoses do not open when connected to the test fittings. If available, use hoses without shut-off valves. If hoses with shut-off valves are used, make sure the valve opens when attached to the test fittings or install an adapter which will activate the valve. The test is not valid if the shut-off valve does not open. 6. Open both gauge set valves and start the vacuum pump. Allow the vacuum pump to operate for a minimum of 45 minutes after the gauge set low pressure gauge indicates 101 kPa (30 in-Hg). The 45 minute evacuation is necessary to remove any refrigerant from oil left in the A/C evaporator core or A/C condenser core. If the refrigerant is not completely removed from the oil, outgassing will degrade the vacuum and appear as a refrigerant leak. 7. If the low pressure gauge reading will not drop to 101 kPa (30 in-Hg) when the valves on the gauge and manifold set are open and the vacuum pump is operating, close the gauge set valves and observe the low pressure gauge. If the pressure rises rapidly to zero, a large leak is indicated. Recheck the test fitting connections and gauge set connections before installing a new A/C evaporator core or A/C condenser core. 8. After evacuating for 45 minutes, close the gauge set valves and stop the vacuum pump. Observe the low pressure gauge; it should remain at the 101 kPa (30 in-Hg) mark. ^ If the low pressure gauge reading rises 34 or more kPa (10 or more in-Hg) of vacuum from the 101 kPa (30 in-Hg) position in 10 minutes, a leak is indicated. ^ If a small leak is suspected, wait 30 minutes and observe the vacuum gauge. ^ If a small amount of vacuum is lost, operate the vacuum pump with gauge valves open for an additional 30 minutes to remove any remaining refrigerant from the oil in the A/C evaporator core or A/C condenser core. Then recheck for loss of vacuum. ^ If a very small leak is suspected, allow the system to set overnight with vacuum applied and check for vacuum loss. 9. If the A/C evaporator core or A/C condenser core does leak, as verified by the above procedure, install a new A/C evaporator core or A/C condenser core. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Service and Repair > Auxiliary Climate Control Evaporator Core: Service and Repair Auxiliary Climate Control REMOVAL 1.

ISSUE The majority of repeat heater core leaks are due to high flow rate or use of poor quality coolant. However, electrolysis should also be checked, especially when repeat repairs have occurred. ACTION If the heater core is leaking, review the location of the leakage and check the condition of the coolant. SERVICE PROCEDURE 1. Review the location of the leakage and check the condition of the coolant: a. If leaks are found on the inlet (or outlet) tubes entering / exiting the heater core, it is most likely due to due to high flow rate - replace the Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Technical Service Bulletins > Customer Interest: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 7055 heater core and install a restrictor in the heater hose closest to the engine block, reference Workshop Manual, Section 412. b. If leaks are found in the body of the heater core itself, and does not appear to be the result of physical damage like contact or puncture, check the coolant for possible electrolysis. Testing For Electrolysis Check for voltage in the cooling system by touching the negative contact of a voltmeter to the battery ground or a known good ground and suspend the positive lead in the coolant, making sure it is in contact with the coolant but not touching any metal part of the radiator or cooling system. Both AC and DC voltages must be checked. Vehicles normally have DC voltages; however, a faulty engine block heater or faulty diode in the alternator can produce AC voltages. It is understood that coolant is lost due to heater core failure but try to obtain a voltage reading on the old coolant in the engine block before addition to or replacement of. To keep more coolant from exiting the heater core clamp off heater core lines and measure coolant in the engine block. Try not to dilute the original coolant with new coolant during testing if possible. 1. Determine whether coolant condition is acceptable. a. Remove both cables from the battery and ensure they do not contact each other or the vehicle. b. Touch negative lead of voltmeter to engine ground and positive lead in the coolant. NOTE POSITIVE TEST PROBE IS IN THE COOLANT FOR TESTING. c. Check the voltage in the cooling system. If less than or equal to 0.4 volts (V) OK, reconnect battery cables and proceed to Step 2. d. If greater than 0.4 V, flush cooling system thoroughly. e. Recheck voltage less than or equal to 0.4 V. f. Reconnect battery cables. g. Refill the system with appropriate Motorcraft® engine coolant. 2. Check for loose or missing grounds at static conditions. a. Turn off all accessories. Turn ignition on but do not start engine. b. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. c. Voltage less than or equal to 0.4 V on all grounds OK. d. Any one greater than 0.4 V, check and clean ground cable connections. e. Check accessories without using the on off switch on the vehicle instrument panel, use a jumper wire to ground. f. Plug in engine block heater, if equipped, and test. g. Recheck voltage less than or equal to 0.4 V. h. Unplug engine block heater, if equipped. 3. Check for loose, missing, or inadequate grounds. a. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. b. Crank engine but do not start. c. Monitor voltage while cranking. less than or equal to 0.4 V OK d. If greater than 0.4 V, ground or repair starter. e. Start engine and run at about 2000 rpm. f. Turn on all accessories including those customer only uses occasionally such as CB radio, cell phone, etc. g. Test with ground probe to battery ground, engine ground, and vehicle ground sequentially. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Technical Service Bulletins > Customer Interest: > 06-21-19 > Oct > 06 > A/C - Heater Core Electrolysis/Leakage > Page 7056 h. Voltage less than or equal to 0.4 V OK i. If greater than 0.4 V, turn off one item at a time until V drops to less than or equal to 0.4 V. Repair ground to the accessory just identified. j. Recheck voltage less than or equal to 0.4 V k. Turn the DVOM to AC volts. l. Check for ANY AC voltage greater than 0.4. m. If any AC voltage is present then try turning off each accessory one at a time including blower motor and any fan motors. n. If AC voltage is still present then shut engine off and remove B+ from the alternator and tape it up then retest. o. If voltage drop is gradual to less than or equal to 0.4 V, the ground straps may simply be overloaded by added accessories. Test by using heavy gauge jumper to ground. If indicated, install heavier gauge ground strap(s) and recheck. NOTE If vehicle is equipped with electric cooling fans, be sure they cycle during this testing and monitor voltage when they are on and when off. CAUTION DO NOT GROUND HEATER CORE. IF THE HEATER CORE IS GROUNDED, YOU HAVE PROVIDED THE ELECTROLOSIS A PATH THROUGH THE HEATER CORE. THIS WOULD CAUSE THE HEATER CORE TO BECOME AN ANODE OR RECEIVER AND IT WOULD PROMOTE THE ELECTROLOSIS, OR ANY STRAY VOLTAGE TO USE THE COOLANT AS THE GROUND PATH. 4. Refill the engine cooling system, reference Workshop Manual, Section 303-03.

IF IT IS NECESSARY TO OPERATE THE ENGINE WITH THE VEHICLE IN A CLOSED AREA SUCH AS A GARAGE, ALWAYS USE AN EXHAUST COLLECTOR TO VENT THE EXHAUST GASES OUTSIDE THE CLOSED AREA. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. 1. Inspect for evidence of coolant leakage at the heater water hose to heater core attachments. A coolant leak in the heater water hose could follow the heater core tube to the heater core and appear as a leak in the heater core. NOTE: Testing of returned heater cores reveals that a large percentage of heater cores are good and did not require installation of a new heater core. If a heater core leak is suspected, the heater core must be tested by following the plugged heater core component test before the heater core pressure test. Carry out a system inspection by checking the heater system thoroughly. 2. Check the integrity of the heater water hose clamps. NOTE: Spring-type clamps are installed as original equipment. Installation and overtightening of non-specification clamps can cause leakage at the heater water hose connection and damage the heater core. Heater Core Plugged WARNING: THE HEATER CORE INLET HOSE WILL BECOME TOO HOT TO HANDLE IF THE SYSTEM IS WORKING CORRECTLY. 1. Check to see that the engine coolant is at the proper level. 2. Start the engine and turn on the heater. 3. When the engine coolant reaches operating temperature, feel the heater core outlet hose to see if it is hot. If it is not hot: ^ the heater core may have an air pocket. ^ the heater core may be plugged. ^ the thermostat may not be working correctly. Heater Core-Pressure Test Use the radiator/heater core pressure tester to carry out the pressure test. 1. Drain the coolant from the cooling system. NOTE: Due to space limitations, a bench test may be necessary for pressure testing. 2. Disconnect the heater water hoses from the heater core. 3. Install a short piece of heater water hose, approximately 101 mm (4 inches) long on each heater core tube. 4. Fill the heater core and heater water hoses with water and install plug BT-7422-B and adapter BT-7422-A from the radiator/heater core pressure tester in the heater water hose ends. Secure the heater water hoses, plug and adapter with hose clamps. 5. Attach the pump and gauge assembly from the radiator/heater core pressure tester to the adapter. 6. Close the bleed valve at the base of the gauge. Pump 241 kPa (35 psi) of air pressure into the heater core. 7. Observe the pressure gauge for a minimum of three minutes. 8. If the pressure drops, check the heater water hose connections to the core tubes for leaks. If the heater water hoses do not leak, remove the heater core from the vehicle and carry out the bench test. Heater Core Bench Test 1. Remove the heater core from the vehicle. 2. Drain all of the coolant from the heater core. 3. Connect the 101 mm (4 inch) test heater water hoses with plug and adapter to the core tubes. Then connect the radiator/heater core pressure tester to the adapter. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Description and Operation > Page 7083 4.

Ozone Depletion Scientific research performed over the past 15 years links the release of chlorofluorocarbons (CFC)s, also know by the trade name Freon) into the atmosphere to ozone depletion. When CFCs are released into the atmosphere, they eventually reach the ozone layer located in the stratosphere where they react with and destroy ozone molecules. Harmful Effects Ozone depletion and the corresponding increase in UV radiation has been shown to lead to higher incidents of cancer as well as global warming. When viewed from a global perspective, ozone depletion holds an enormous potential for damage. Upper Level Vs. Ground Level Ozone Confusion often arises when we hear about the necessity of the ozone layer and ground level ozone. The ozone layer existing high above the earth is beneficial but the same compound, when located at ground level, is harmful to humans, animals, crops and vegetation. Ground level ozone is a component of smog and forms when hydrocarbons (HC) react with nitrogen oxides (NOx) in the presence of sunlight and heat. Montreal Protocol In response to the growing body of evidence demonstrating the detrimental effects of (CFC)s, 24 countries and the European community met in Montreal, Canada, in 1987 to establish standards for the control of (CFC)s. Since that time, a total of 132 countries have become signatories to this agreement leading to an end of production of R12 in December, 1995, in all developed countries. As established by the Montreal Protocol, R12 production in developed countries has ceased. Clean Air Act The United States Congress, acting in response to the Montreal Protocol, banned production of (CFC)s by the year 2000. Congress also amended the Clean Air Act in an effort to control both the production and use of (CFC)s for refrigerant applications including mobile vehicle air conditioning systems.

The A/C pressure sensor provides a voltage signal to the Powertrain Control Module (PCM) that is proportional to the A/C pressure. The PCM uses this information for A/C clutch control, fan control and idle speed control. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 7223 Refrigerant Pressure Sensor / Switch: Description and Operation A/C Pressure Switch A/C Cycling Switch A/C Cycling Switch The A/C cycling switch is mounted on a Schrader valve-type fitting on the top of the suction accumulator. ^ A valve depressor, located inside the threaded end of the A/C cycling switch, presses in on the Schrader valve stem. ^ This allows the suction pressure inside the suction accumulator to control the operation of the A/C cycling switch. ^ The electrical switch contacts open when the suction pressure drops to 152 - 193 kPa (22 - 28 psi). ^ The contacts close when the suction pressure rises to 276 - 324 kPa (40 - 47 psi). ^ When the A/C cycling switch contacts close, the A/C clutch field coil is energized. ^ When the A/C cycling switch contacts open, the A/C clutch field coil is deenergized and compressor operation stops. ^ The A/C cycling switch will control the A/C evaporator core pressure at a point where the plate/fin surface temperature will be maintained slightly above freezing. ^ This prevents icing of the A/C evaporator core and blockage of airflow. ^ It is not necessary to discharge the refrigerant system to remove the A/C cycling switch. Wide Open Throttle A/C Cut-Off Wide Open Throttle A/C Cut-Off Mustang The Wide Open Throttle Air Conditioning Cut-off (WAC) output is used by the PCM to disengage the A/C clutch when A/C compressor operation is not desirable. Under normal conditions, with the A/C off, the PCM will ground the WAC output, which opens the normally closed WOT A/C cut-off relay inside the constant control relay module. When the A/C demand switch is turned on, and the A/C cycling switch and A/C high pressure switch high pressure contacts are closed, voltage is supplied to the WOT A/C cut-off relay contacts and to the ACCS circuit. The voltage on the ACCS circuit indicates to the PCM that A/C is requested. The PCM will then verify that A/C clutch operation is desirable (for example, engine not cranking, overheated or not at WOT). If A/C clutch operation is desirable, the PCM will adjust idle speed as necessary and "unground" the WAC output. This closes the normally closed WOT A/C cut-off relay and allows voltage to be supplied to the A/C clutch. All Others For these applications, the wide open throttle A/C cutoff relay (may be referred to as the A/C clutch relay) is normally open. There is no direct electrical connection between the A/C switch or EATC Module and the A/C clutch. The PCM will receive a signal indicating that A/C is requested (for some applications, this message is sent through the BUS + and BUS - circuits). When A/C is requested, the PCM will check other A/C related inputs that are available (such as ACP (SW), ACCS). If these inputs indicate A/C operation is OK, and the engine conditions are OK (such as coolant temperature, engine rpm, throttle position), the PCM will ground the WAC output, closing the relay contacts and sending voltage to the A/C clutch. Air Conditioning Cycling Switch PCM Inputs Air Conditioning Cycling Switch The Air Conditioning (A/C) cycling switch may be wired to either the ACCS or ACPSW PCM input. When the A/C cycling switch opens, the PCM will turn off the A/C clutch. For information on the specific function of the A/C cycling switch, refer to Climate Control system. The A/C Cycling Switch (ACCS) circuit to the PCM provides a voltage signal which indicates when the A/C is requested. When the A/C demand switch is turned on, and both the A/C cycling switch and the high pressure contacts of the A/C high pressure switch (if equipped and in circuit) are closed, voltage is supplied to the ACCS circuit at the PCM. Refer to the applicable Wiring Diagram for vehicle specific wiring. If the ACCS signal is not received by the PCM, the PCM circuit will not allow the A/C to operate. For additional information, refer to PCM outputs, wide open throttle air conditioning cutoff. NOTE: The Town Car, Continental, LS6/LS8 and Windstar do not have a dedicated (separate) input to the PCM indicating that A/C is requested. This information is received by the PCM through the BUS + and BUS - (SCP) communication. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 7224 Air Conditioning High Pressure Switch Typical Air Conditioning Pressure Sensor Air Conditioning High Pressure Switch The A/C high pressure switch is used for additional A/C system pressure control. The A/C high pressure switch is either dual function for two-speed electric fan applications or single function for all others. For refrigerant containment control, the normally closed high pressure contacts open at a predetermined A/C pressure. This will result in the A/C turning off, preventing the A/C pressure from rising to a level that would open the A/C high pressure relief valve. For fan control, the normally open medium pressure contacts close at a predetermined A/C pressure. This grounds the ACPSW circuit input to the PCM. The PCM will then turn on the high speed fan to help reduce the pressure. The A/C pressure cutoff switch is used to interrupt A/C compressor operation in the event of high system discharge pressures. ^ The A/C pressure cutoff switch is mounted on a Schrader valve-type fitting on the high pressure side of the A/C manifold and tube. ^ A valve depressor, located inside the threaded end of the A/C pressure cutoff switch, presses on the Schrader valve stem. ^ This allows the A/C pressure cutoff switch to monitor the compressor discharge pressure. ^ When the compressor discharge pressure rises to approximately 2,896 kPa (420 psi), the switch contacts open, disengaging the A/C compressor. ^ When the pressure drops to approximately 1724 kPa (250 psi) the contacts close to allow operation of the A/C compressor. ^ It is not necessary to discharge the refrigerant system to remove the A/C pressure cutoff switch. For additional information, refer to the Wiring Diagrams. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Service and Repair > Compressor Cut-Off/Cycling Switch Refrigerant Pressure Sensor / Switch: Service and Repair Compressor Cut-Off/Cycling Switch REMOVAL 1.

The A/C blower motor speed control is controlled by switching the control signal voltage of 5 volts OFF and ON 2,000 times per second. By varying the ratio of time on (+5 volts) to time off (0 volts), the EATC module tells the A/C blower motor speed control how fast the blower motor should run. The A/C blower motor speed control has the following features: ^ Has circuitry to protect the blower motor from burning out in the event of a locked rotor condition. ^ Can compensate for changes in battery positive voltage (B+) which prevents the blower speed from slowing down when the engine is idling and will provide up to a maximum of 30 amperes for blower motor operation with battery voltages between 10 and 16 volts. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Relays and Modules - HVAC > Control Module HVAC > Component Information > Diagrams > Page 7257 Control Module HVAC: Service and Repair REMOVAL 1.

The A/C pressure sensor provides a voltage signal to the Powertrain Control Module (PCM) that is proportional to the A/C pressure. The PCM uses this information for A/C clutch control, fan control and idle speed control. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 7307 Refrigerant Pressure Sensor / Switch: Description and Operation A/C Pressure Switch A/C Cycling Switch A/C Cycling Switch The A/C cycling switch is mounted on a Schrader valve-type fitting on the top of the suction accumulator. ^ A valve depressor, located inside the threaded end of the A/C cycling switch, presses in on the Schrader valve stem. ^ This allows the suction pressure inside the suction accumulator to control the operation of the A/C cycling switch. ^ The electrical switch contacts open when the suction pressure drops to 152 - 193 kPa (22 - 28 psi). ^ The contacts close when the suction pressure rises to 276 - 324 kPa (40 - 47 psi). ^ When the A/C cycling switch contacts close, the A/C clutch field coil is energized. ^ When the A/C cycling switch contacts open, the A/C clutch field coil is deenergized and compressor operation stops. ^ The A/C cycling switch will control the A/C evaporator core pressure at a point where the plate/fin surface temperature will be maintained slightly above freezing. ^ This prevents icing of the A/C evaporator core and blockage of airflow. ^ It is not necessary to discharge the refrigerant system to remove the A/C cycling switch. Wide Open Throttle A/C Cut-Off Wide Open Throttle A/C Cut-Off Mustang The Wide Open Throttle Air Conditioning Cut-off (WAC) output is used by the PCM to disengage the A/C clutch when A/C compressor operation is not desirable. Under normal conditions, with the A/C off, the PCM will ground the WAC output, which opens the normally closed WOT A/C cut-off relay inside the constant control relay module. When the A/C demand switch is turned on, and the A/C cycling switch and A/C high pressure switch high pressure contacts are closed, voltage is supplied to the WOT A/C cut-off relay contacts and to the ACCS circuit. The voltage on the ACCS circuit indicates to the PCM that A/C is requested. The PCM will then verify that A/C clutch operation is desirable (for example, engine not cranking, overheated or not at WOT). If A/C clutch operation is desirable, the PCM will adjust idle speed as necessary and "unground" the WAC output. This closes the normally closed WOT A/C cut-off relay and allows voltage to be supplied to the A/C clutch. All Others For these applications, the wide open throttle A/C cutoff relay (may be referred to as the A/C clutch relay) is normally open. There is no direct electrical connection between the A/C switch or EATC Module and the A/C clutch. The PCM will receive a signal indicating that A/C is requested (for some applications, this message is sent through the BUS + and BUS - circuits). When A/C is requested, the PCM will check other A/C related inputs that are available (such as ACP (SW), ACCS). If these inputs indicate A/C operation is OK, and the engine conditions are OK (such as coolant temperature, engine rpm, throttle position), the PCM will ground the WAC output, closing the relay contacts and sending voltage to the A/C clutch. Air Conditioning Cycling Switch PCM Inputs Air Conditioning Cycling Switch The Air Conditioning (A/C) cycling switch may be wired to either the ACCS or ACPSW PCM input. When the A/C cycling switch opens, the PCM will turn off the A/C clutch. For information on the specific function of the A/C cycling switch, refer to Climate Control system. The A/C Cycling Switch (ACCS) circuit to the PCM provides a voltage signal which indicates when the A/C is requested. When the A/C demand switch is turned on, and both the A/C cycling switch and the high pressure contacts of the A/C high pressure switch (if equipped and in circuit) are closed, voltage is supplied to the ACCS circuit at the PCM. Refer to the applicable Wiring Diagram for vehicle specific wiring. If the ACCS signal is not received by the PCM, the PCM circuit will not allow the A/C to operate. For additional information, refer to PCM outputs, wide open throttle air conditioning cutoff. NOTE: The Town Car, Continental, LS6/LS8 and Windstar do not have a dedicated (separate) input to the PCM indicating that A/C is requested. This information is received by the PCM through the BUS + and BUS - (SCP) communication. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Component Information > Description and Operation > A/C Pressure Sensor > Page 7308 Air Conditioning High Pressure Switch Typical Air Conditioning Pressure Sensor Air Conditioning High Pressure Switch The A/C high pressure switch is used for additional A/C system pressure control.

NOTE: The safing sensor is internal to the RCM and is not repaired separately. The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster. When the ignition is cycled (turned OFF and then ON), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash a two-digit Lamp Fault Code (LFC). The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the Data Link Connector (DLC), using a scan tool. If the air bag indicator does not function, and a system fault is detected, the RCM will signal the GEM to activate the audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair. LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After the fault has been corrected, the next highest priority fault will be displayed. The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that an air bag deployment is required. The backup power supply will deplete its stored energy approximately 1 minute after the battery ground cable is disconnected. Sensor WARNING: THE RESTRAINTS CONTROL MODULE (RCM) ORIENTATION IS CRITICAL FOR CORRECT SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HAS BEEN INVOLVED IN A COLLISION IN WHICH THE CENTER TUNNEL AREA HAS BEEN DAMAGED, INSPECT THE MOUNTING AND BRACKET FOR DEFORMATION. IF DAMAGED, THE RCM MUST BE REPLACED WHETHER OR NOT THE AIR BAGS HAVE DEPLOYED. IN ADDITION, MAKE SURE THE AREA OF THE RCM MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION. The SRS uses four crash sensors. Two of the sensors are integral to the RCM and not separately serviceable. In addition, there are two side crash sensors mounted beneath their respective seats. The RCM is mounted to the center tunnel beneath the instrument panel. Mounting orientation is critical for correct operation of all crash sensors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag Control Module > Component Information > Service and Repair > Removal and Installation Air Bag Control Module: Service and Repair Removal and Installation REMOVAL AND INSTALLATION WARNING: ^ TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY FRONT OR SIDE AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS AND BEFORE SERVICING, REPLACING, ADJUSTING OR STRIKING COMPONENTS NEAR THE FRONT OR SIDE AIR BAG SENSORS, SUCH AS DOORS, INSTRUMENT PANEL, CONSOLE, DOOR LATCHES, STRIKERS, SEATS AND HOOD LATCHES. ^ THE SIDE AIR BAG SENSORS ARE LOCATED AT OR NEAR THE BASE OF THE B-PILLAR. ^ TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT LEAST ONE MINUTE.

NOTE: The safing sensor is internal to the RCM and is not repaired separately. The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster. When the ignition is cycled (turned OFF and then ON), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash a two-digit Lamp Fault Code (LFC). The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the Data Link Connector (DLC), using a scan tool. If the air bag indicator does not function, and a system fault is detected, the RCM will signal the GEM to activate the audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair. LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After the fault has been corrected, the next highest priority fault will be displayed. The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that an air bag deployment is required. The backup power supply will deplete its stored energy approximately 1 minute after the battery ground cable is disconnected. Sensor WARNING: THE RESTRAINTS CONTROL MODULE (RCM) ORIENTATION IS CRITICAL FOR CORRECT SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HAS BEEN INVOLVED IN A COLLISION IN WHICH THE CENTER TUNNEL AREA HAS BEEN DAMAGED, INSPECT THE MOUNTING AND BRACKET FOR DEFORMATION. IF DAMAGED, THE RCM MUST BE REPLACED WHETHER OR NOT THE AIR BAGS HAVE DEPLOYED. IN ADDITION, MAKE SURE THE AREA OF THE RCM MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION. The SRS uses four crash sensors. Two of the sensors are integral to the RCM and not separately serviceable. In addition, there are two side crash sensors mounted beneath their respective seats. The RCM is mounted to the center tunnel beneath the instrument panel. Mounting orientation is critical for correct operation of all crash sensors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Service and Repair > Removal and Installation Air Bag Control Module: Service and Repair Removal and Installation REMOVAL AND INSTALLATION WARNING: ^ TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY FRONT OR SIDE AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS AND BEFORE SERVICING, REPLACING, ADJUSTING OR STRIKING COMPONENTS NEAR THE FRONT OR SIDE AIR BAG SENSORS, SUCH AS DOORS, INSTRUMENT PANEL, CONSOLE, DOOR LATCHES, STRIKERS, SEATS AND HOOD LATCHES. ^ THE SIDE AIR BAG SENSORS ARE LOCATED AT OR NEAR THE BASE OF THE B-PILLAR. ^ TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT LEAST ONE MINUTE.

This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. 1. Turn all vehicle accessories OFF. 2. Turn the ignition switch to OFF. 3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 5. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. The side impact sensors (if equipped) are located at or near the base of the B-pillars. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). 6. Disconnect the battery ground cable (14301) and wait at least one minute. Repowering Procedure Warning: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards. 1. Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected. 2. Turn the ignition switch from OFF to ON. 3. Install the RCM fuse F22 (10A) to the CJB and close the cover. Warning: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected. 4. Connect the battery ground cable. 5. Prove out the supplemental restraint system (SRS) as follows: Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either: fail to light. - remain lit continuously. - flash. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Safety Belt Systems <--> [Seat Belt Systems] > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 7493 The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. All Vehicles 1. Move and tilt the front seats to their highest and most forward position. 2. Turn all vehicle accessories OFF. 3. Turn the ignition switch to OFF. 4. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 5. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 6. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Safety Belt Systems <--> [Seat Belt Systems] > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 7494 The side impact sensors (if equipped) are located at or near the base of the B-pillars.

About 20 cm (8 in) can be added to the belt length by using a safety belt extension. Safety belt extensions are available through any Ford or Lincoln Mercury dealer parts department at no cost. Safety belt extensions are only available with black webbing. There are two extension assemblies available one for the front seating positions and one for the rear seating positions. They are not interchangeable. Use only extensions manufactured by the same supplier as the safety belt. Manufacturer identification is located at the end of the webbing on the label. Also, use the safety belt extension only if the safety belt is too short for you when fully extended. Do not use extension to change the fit of the shoulder belt across the torso. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Safety Belt Systems <--> [Seat Belt Systems] > Seat Belt Height Adjuster > Component Information > Specifications Seat Belt Height Adjuster: Specifications Safety Belt Height Adjuster 34-46 Nm Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Safety Belt Systems <--> [Seat Belt Systems] > Seat Belt Height Adjuster > Component Information > Service and Repair > Removal Installation Seat Belt Height Adjuster: Service and Repair Removal Installation Height Adjuster - Front Safety Belt Bolt Bit Special Service Tool(s) REMOVAL NOTE: This procedure is for the LH side; RH side is similar. 1.

All outboard continuous-loop, three-point retractor systems, except the driver position, are equipped with the ALR system. This system is used when installing a child safety seat in an outboard seating position or when a tight lap/shoulder belt is desired by the occupant. The ALR system is automatically engaged when the webbing is fully extracted from the retractor. As the webbing is retracted back onto the spool, an audible clicking sound is made indicating the retractor is in the ALR mode. The ALR mode is automatically disengaged when most of the webbing is retracted back onto the spool. The ALR mode is disengaged when the audible clicking sound ceases and the webbing is free to move in or out of the retractor indicating a normal mode of operation. The automatic locking mode must be used when installing a child safety seat in the front passenger and rear outboard passenger seating positions where dual locking mode retractors are provided. The second row 60% portion of the 40/60 split bench seat center passenger retractor is equipped with ALR only. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Restraint Systems > Safety Belt Systems <--> [Seat Belt Systems] > Seat Belt Retractor > Component Information > Service and Repair > Retractor - Front, Driver Side Seat Belt Retractor: Service and Repair Retractor - Front, Driver Side Safety Belt Bolt Bit Special Service Tool(s) REMOVAL NOTE: This procedure is for the LH side; the RH side is similar. 1.

In order to properly diagnose the concern with the keyless entry keypad, it is important to identify whether the keypad is a factory installed style (wired) or a Genuine Ford Accessory (GFA) radio frequency (RF) style keypad. ACTION Use the following Service Procedure to identify GFA RF keypads and provide diagnostic service tips. SERVICE PROCEDURE IDENTIFICATION: 1. Production installed keyless entry keypads are mounted flush with the surface of the vehicle and are wired directly to the module controlling the vehicle's keyless entry system. This style keypad can be diagnosed using the appropriate Workshop Manual (WSM), Section 501-14. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Antitheft and Alarm Systems > Keyless Entry > Keyless Entry Key-Pad > Component Information > Technical Service Bulletins > Keyless Entry - Keypad Diagnostics > Page 7668 2. Dealer installed GFA RF keypads are adhesive backed and protrude approximately 1/2" (13 mm) from the surface of the vehicle and there are no specific diagnostics available in the WSM (Figure 1). NOTE THIS RF KEYPAD WAS ALSO US[D IN PRODUCTION ON 2004 F-SUPER DUTY VEHICLES BUILT PRIOR TO 12/3/2003. REFER TO WSM, SECTION 501-14 FOR RF KEYPAD DIAGNOSTICS FOR THESE VEHICLES. GENUINE FORD ACCESSORY KEYPAD DIAGNOSTIC TIPS 1. The keypad operates similarly to a remote keyless entry (RKE) transmitter and is programmed using a similar procedure. Although the RF keypad is not specifically addressed in the WSM, the RKE transmitter programming portion of the WSM, Section 501-14 can be used as a guide NOTE THE 7-8 AND 9-0 BUTTONS ON THE KEYPAD MUST BE PRESSED SIMULTANEOUSLY DURING THE PROCEDURE IN ORDER FOR THE KEYPAD TO BE RECOGNIZED AS AN ADDITIONAL REMOTE TRANSMITTER. Since the GFA RF keypad is essentially another RKE transmitter, the transmitter diagnostic pinpoint tests in the vehicle's WSM can also be referenced even though the buttons serving the lock / unlock functions will differ 2. The GFA RF keypad is serviced as an assembly. The internal battery cannot be replaced separately. 3. If the master code or owner selectable code is lost or forgotten, the GFA RF keypad must be replaced. These codes are not stored in any vehicle module (with the exception of 2004 F-Super Duty vehicles produced prior to 12/3/2003). 4. The GFA RF keypad and all RKE transmitters (the number of transmitters allowable will vary by vehicle) must be reprogrammed together anytime the keypad is replaced, an RKE transmitter is replaced, or the module controlling the keyless entry system on the vehicle (GEM/SJB/VSM/DDM etc.) is replaced. NOTE THERE IS AN EXCEPTION TO TIP 4 FOR VEHICLES EQUIPPED WITH INTEGRATED KEYHEAD TRANSMITTERS (IKTs) (FUSION/MILAN/ZEPHYR). THE GFA RF KEYPADS FOR VEHICLES WITH IKTs MUST BE PROGRAMMED INDEPENDENTLY FROM THE IKTs. TURN THE IGNITION FROM "OFF" TO "RUN" 8 TIMES WITHIN 10 SECONDS, WITH THE 8TH TIME ENDING IN "RUN". THE DOOR LOCKS WILL CYCLE TO CONFIRM ENTERING PROGRAMMING MODE. PRESS THE 7-8 AND 9-0 BUTTON ON THE KEYPAD SIMULTANEOUSLY TO SEND A LOCK SIGNAL. TURN IGNITION TO OFF. THE LOCKS WILL CYCLE AGAIN TO INDICATE THE END OF THE PROGRAMMING MODE. 5. The keypad will normally illuminate for 5 seconds after one or more buttons are pressed, and the illumination will immediately turn off if the 7-8 and 9-0 buttons are pressed simultaneously (lock all doors). The keypad contains an optical sensor and will not illuminate under bright lighting conditions. The keypad may only illuminate briefly in colder temperatures in order to maximize the battery power available to transmit a lock/unlock signal. The temperature at which this occurs will vary depending upon the keypad battery age and condition. Both of these conditions are a normal function of the Power Save Mode and do not indicate a need to replace the keypad. 6. After entering the keypad code, the system may unlock the driver's door, lock it, then unlock it again, and the keypad will not even briefly illuminate. This is the Alert Mode and is an indication that battery power is very low and the keypad must be replaced. 7. The keypad also contains an Anti-scan feature. If the wrong code has been entered 7 times (35 consecutive button presses) the keypad is disabled for one minute and the keypad lamp will flash during this time. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Antitheft and Alarm Systems > Keyless Entry > Keyless Entry Key-Pad > Component Information > Technical Service Bulletins > Keyless Entry - Keypad Diagnostics > Page 7669 WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage DEALER CODING CONDITION BASIC PART NO.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7733 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7734 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7735 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7736 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7737 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7738 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7739 Multifunction Electronic Control Modules: Connector Views Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7740 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7741 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7742 Multifunction Electronic Control Modules: Electrical Diagrams Diagram 59-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7743 Diagram 59-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7744 Diagram 59-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7745 Diagram 59-4 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7746 Diagram 59-5 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Page 7747 Multifunction Electronic Control Modules: Service Precautions CAUTION: ^ Prior to removal of module, it is necessary to upload module configuration information to scan tool.

ISSUE A "whining"/"buzzing" noise in the speakers of the entertainment radio or two-way radio on vehicles with an in-tank electric fuel pump may be caused by electrical noise from the fuel pump. ACTION Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Speaker > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Speaker: > 01-7-3 > Apr > 01 > Fuel Pump - Whine Heard Through Radio Speakers > Page 7839 Install an electronic noise Radio Frequency Interference (RFI) Filter (F1PZ-18B925-A) on the fuel pump inside the fuel tank. Refer to the following Test Procedure to confirm that the concern exists, then refer to the Service Procedure for repair details. NOTE SOME LIGHT TRUCKS REQUIRE ONE (1) RFI FILTER FOR EACH IN-TANK ELECTRIC FUEL PUMP ON MULTI-TANK VEHICLES. NOTE THIS TSB DOES NOT INCLUDE TAURUS FLEXIBLE FUEL VEHICLES (FFVS) OR 1999 RANGER 3.0L FFVS. TEST PROCEDURE Fuel pump radio noise is relatively constant and changes only slightly with vehicle speed. If the frequency of the noise varies or the noise comes and goes with the vehicle speed, then it is not the fuel pump and this fix will not be effective. The following procedure will help determine if the fuel pump is the cause of the radio noise: 1. Turn on the radio before the key is turned on (assuming the radio will operate without the ignition key - you may need to put the ignition key in the Accessory position). 2. Turn the ignition key to the Run position (do not start the engine). 3. The fuel pump should run for about 1 second with the key in the Run position with the engine not running. Listen for noise in the radio. If noise is present while the pump is running and stops when the pump stops, then the noise is being generated by the pump and this procedure should help. SERVICE PROCEDURE 1. Remove the fuel pump sender assembly from the fuel tank. Refer to the appropriate model year Workshop Manual for removal procedure. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Radio, Stereo, and Compact Disc > Speaker > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Speaker: > 01-7-3 > Apr > 01 > Fuel Pump - Whine Heard Through Radio Speakers > Page 7840 2.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7878 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7879 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7880 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7881 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7882 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7883 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7884 Multifunction Electronic Control Modules: Connector Views Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7885 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7886 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7887 Multifunction Electronic Control Modules: Electrical Diagrams Diagram 59-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7888 Diagram 59-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7889 Diagram 59-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7890 Diagram 59-4 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 7891 Diagram 59-5 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional Equipment > Multifunction Electronic Control Modules <--> [General Module] > Component Information > Diagrams > Page 7892 Multifunction Electronic Control Modules: Service Precautions CAUTION: ^ Prior to removal of module, it is necessary to upload module configuration information to scan tool.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 7951 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 7952 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 7953 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8057 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8058 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8059 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8060 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8061 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8062 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8063 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8064 Trailer Connector: Electrical Diagrams Diagram 95-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8065 Diagram 95-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 8066 Diagram 95-3 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trip Computer > Component Information > Locations Trip Computer: Locations Overhead Trip Computer Module In front of overhead console. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trip Computer > Component Information > Locations > Page 8070 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Accessories and Optional Equipment > Trip Computer > Component Information > Locations > Page 8071 Trip Computer: Testing and Inspection For further information regarding the diagnosis of this component and the system that is a part of, please refer to Driver/Vehicle Information Display; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Bumper > Front Bumper > Front Bumper Bracket > System Information > Service and Repair Front Bumper Bracket: Service and Repair BUMPER BRACKET - FRONT, EXPEDITION Removal 1.

This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. 1. Turn all vehicle accessories OFF. 2. Turn the ignition switch to OFF. 3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 5. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. The side impact sensors (if equipped) are located at or near the base of the B-pillars. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). 6. Disconnect the battery ground cable (14301) and wait at least one minute. Repowering Procedure Warning: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards. 1. Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected. 2. Turn the ignition switch from OFF to ON. 3. Install the RCM fuse F22 (10A) to the CJB and close the cover. Warning: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected. 4. Connect the battery ground cable. 5. Prove out the supplemental restraint system (SRS) as follows: Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either: fail to light. - remain lit continuously. - flash. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Interior Moulding / Trim > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Air Bag Disarming and Arming > Page 8312 The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON.

In order to properly diagnose the concern with the keyless entry keypad, it is important to identify whether the keypad is a factory installed style (wired) or a Genuine Ford Accessory (GFA) radio frequency (RF) style keypad. ACTION Use the following Service Procedure to identify GFA RF keypads and provide diagnostic service tips. SERVICE PROCEDURE IDENTIFICATION: 1. Production installed keyless entry keypads are mounted flush with the surface of the vehicle and are wired directly to the module controlling the vehicle's keyless entry system. This style keypad can be diagnosed using the appropriate Workshop Manual (WSM), Section 501-14. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Locks > Keyless Entry > Keyless Entry Key-Pad > Component Information > Technical Service Bulletins > Keyless Entry - Keypad Diagnostics > Page 8367 2. Dealer installed GFA RF keypads are adhesive backed and protrude approximately 1/2" (13 mm) from the surface of the vehicle and there are no specific diagnostics available in the WSM (Figure 1). NOTE THIS RF KEYPAD WAS ALSO US[D IN PRODUCTION ON 2004 F-SUPER DUTY VEHICLES BUILT PRIOR TO 12/3/2003. REFER TO WSM, SECTION 501-14 FOR RF KEYPAD DIAGNOSTICS FOR THESE VEHICLES. GENUINE FORD ACCESSORY KEYPAD DIAGNOSTIC TIPS 1. The keypad operates similarly to a remote keyless entry (RKE) transmitter and is programmed using a similar procedure. Although the RF keypad is not specifically addressed in the WSM, the RKE transmitter programming portion of the WSM, Section 501-14 can be used as a guide NOTE THE 7-8 AND 9-0 BUTTONS ON THE KEYPAD MUST BE PRESSED SIMULTANEOUSLY DURING THE PROCEDURE IN ORDER FOR THE KEYPAD TO BE RECOGNIZED AS AN ADDITIONAL REMOTE TRANSMITTER. Since the GFA RF keypad is essentially another RKE transmitter, the transmitter diagnostic pinpoint tests in the vehicle's WSM can also be referenced even though the buttons serving the lock / unlock functions will differ 2. The GFA RF keypad is serviced as an assembly. The internal battery cannot be replaced separately. 3. If the master code or owner selectable code is lost or forgotten, the GFA RF keypad must be replaced. These codes are not stored in any vehicle module (with the exception of 2004 F-Super Duty vehicles produced prior to 12/3/2003). 4. The GFA RF keypad and all RKE transmitters (the number of transmitters allowable will vary by vehicle) must be reprogrammed together anytime the keypad is replaced, an RKE transmitter is replaced, or the module controlling the keyless entry system on the vehicle (GEM/SJB/VSM/DDM etc.) is replaced. NOTE THERE IS AN EXCEPTION TO TIP 4 FOR VEHICLES EQUIPPED WITH INTEGRATED KEYHEAD TRANSMITTERS (IKTs) (FUSION/MILAN/ZEPHYR). THE GFA RF KEYPADS FOR VEHICLES WITH IKTs MUST BE PROGRAMMED INDEPENDENTLY FROM THE IKTs. TURN THE IGNITION FROM "OFF" TO "RUN" 8 TIMES WITHIN 10 SECONDS, WITH THE 8TH TIME ENDING IN "RUN". THE DOOR LOCKS WILL CYCLE TO CONFIRM ENTERING PROGRAMMING MODE. PRESS THE 7-8 AND 9-0 BUTTON ON THE KEYPAD SIMULTANEOUSLY TO SEND A LOCK SIGNAL. TURN IGNITION TO OFF. THE LOCKS WILL CYCLE AGAIN TO INDICATE THE END OF THE PROGRAMMING MODE. 5. The keypad will normally illuminate for 5 seconds after one or more buttons are pressed, and the illumination will immediately turn off if the 7-8 and 9-0 buttons are pressed simultaneously (lock all doors). The keypad contains an optical sensor and will not illuminate under bright lighting conditions. The keypad may only illuminate briefly in colder temperatures in order to maximize the battery power available to transmit a lock/unlock signal. The temperature at which this occurs will vary depending upon the keypad battery age and condition. Both of these conditions are a normal function of the Power Save Mode and do not indicate a need to replace the keypad. 6. After entering the keypad code, the system may unlock the driver's door, lock it, then unlock it again, and the keypad will not even briefly illuminate. This is the Alert Mode and is an indication that battery power is very low and the keypad must be replaced. 7. The keypad also contains an Anti-scan feature. If the wrong code has been entered 7 times (35 consecutive button presses) the keypad is disabled for one minute and the keypad lamp will flash during this time. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Locks > Keyless Entry > Keyless Entry Key-Pad > Component Information > Technical Service Bulletins > Keyless Entry - Keypad Diagnostics > Page 8368 WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage DEALER CODING CONDITION BASIC PART NO.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8419 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8420 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8421 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8422 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8423 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8424 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 8425 Diagram 56-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Memory Positioning Systems > Seat Memory Switch > Component Information > Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Control Module > Component Information > Testing and Inspection Power Mirror Control Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Mirrors; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Diagrams Power Mirror Switch: Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Diagrams > Page 8436 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Testing and Inspection > Exterior Rear View Mirror Switch Power Mirror Switch: Testing and Inspection Exterior Rear View Mirror Switch Component Testing Procedure (Part 1 Of 2) Component Testing Procedure (Part 2 Of 2) Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Testing and Inspection > Exterior Rear View Mirror Switch > Page 8439 Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Testing and Inspection > Exterior Rear View Mirror Switch > Page 8440 Power Mirror Switch: Testing and Inspection Power Folding Mirror Switch Component Testing Procedure Terminals Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Mirrors > Power Mirror Switch > Component Information > Testing and Inspection > Exterior Rear View Mirror Switch > Page 8441 Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Application and ID > Paint Codes Paint: Application and ID Paint Codes The Vehicle Certification (VC) label contains the manufacturer name, the month and year of manufacture, the certification statement, and the VIN.

This may be due to the water trough being separated from the trough guide on either side, as a result of a broken trough guide. ACTION Check if the water trough is securely attached to the trough guide at each end. Check for damage to the lifter arm assemblies at the joint where the trough guide metal rods attach. Refer to the following Service Procedure for details. SERVICE PROCEDURE NOTE IF ROOF OPENING PANEL SERVICE IS PERFORMED BY A SUBLET FACILITY, MAKE SURE THIS ARTICLE IS REFERENCED DURING SERVICE. The trough guide is a small plastic piece with a metal rod attachment which is responsible for guiding the roof opening panel water trough along the roof opening panel track as the panel opens and closes. The roof opening panel water trough is a metal tray that attaches to the trough guides at each end and is responsible for collecting water as the glass panel tilts and operates. In cases where a water trough becomes loose, it will rattle against the rearward portion of the roof opening panel assembly during driving. Likewise, it may result in the roof opening glass opening without the interior shade opening simultaneously. It may also prevent the glass panel from fully opening or closing. A separated water trough may lead to a water leak into the vehicle at the rear of the roof opening glass when the moonroof is opened. Check if the water trough is securely attached to the trough guide at each end. Check for damage to the lifter arm assemblies at the joint where the trough guide metal rods attach. Before replacing the guides and trough, inspect the roof opening panel track for broken plastic guide pieces, and remove them. Be sure to discard the original water trough and use a new trough, even if damage to the trough itself is not apparent. The new water trough design has fully enclosed screw holes rather than open-ended slots for securing it to the trough guides. If there is no damage to the lifter arm assemblies, but the water trough and guide are separated on either side, replace BOTH trough guides AND the water trough (serviceable subassemblies of the roof opening panel assembly) according to the following replacement instructions. If there is damage to the lifter arm assembly or assemblies, replace the moonroof assembly according to Workshop Manual Section 501-17. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Roof and Associated Components > Sunroof / Moonroof > Sunroof / Moonroof Track > Component Information > Technical Service Bulletins > Customer Interest: > 03-11-10 > Jun > 03 > Body - Moonroof Water Leaks/Won't Open Properly > Page 8518 Rear Trough Guide Replacement 1.

Likewise, it may result in the roof opening glass opening without the interior shade opening simultaneously. It may also prevent the glass panel from fully opening or closing. A separated water trough may lead to a water leak into the vehicle at the rear of the roof opening glass when the moonroof is opened. Check if the water trough is securely attached to the trough guide at each end. Check for damage to the lifter arm assemblies at the joint where the trough guide metal rods attach. Before replacing the guides and trough, inspect the roof opening panel track for broken plastic guide pieces, and remove them. Be sure to discard the original water trough and use a new trough, even if damage to the trough itself is not apparent. The new water trough design has fully enclosed screw holes rather than open-ended slots for securing it to the trough guides. If there is no damage to the lifter arm assemblies, but the water trough and guide are separated on either side, replace BOTH trough guides AND the water trough (serviceable subassemblies of the roof opening panel assembly) according to the following replacement instructions. If there is damage to the lifter arm assembly or assemblies, replace the moonroof assembly according to Workshop Manual Section 501-17. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Body and Frame > Roof and Associated Components > Sunroof / Moonroof > Sunroof / Moonroof Drain > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Sunroof / Moonroof Drain: > 03-11-10 > Jun > 03 > Body - Moonroof Water Leaks/Won't Open Properly > Page 8560 Rear Trough Guide Replacement 1.

See Figure 1. Note that the revised SCDS has a different electrical connector. A jumper adapter (which is included in the parts kit) is required when replacing the old SCDS with the revised SCDS. SCDS Location In most late model year vehicles involved in this recall, the SCDS is located on the master cylinder. In early model year vehicles (1992-1998), the SCDS may be located on the master cylinder but is often found on a brake line distribution block or on the brake proportioning valve. If in doubt, just follow the metal brake lines from the master cylinder until the switch is found. ^ On early model year E-Series vehicles, the SCDS is located on the left frame rail. ^ On E-450 models only, remove the 3 screws and position the coolant degas bottle forward to allow access to the SCDS and servo. ^ On F-53 vehicles, if the SCDS is not located on the master cylinder, it may be located in a brake line junction block approximately 457 mm (18 in) below the master cylinder. It may be necessary to reposition wiring harnesses and/or remove add-on equipment in order to locate the switch. ^ On 1993 MARK VIII vehicles, the steering wheel intermediate shaft needs to be disconnected from the inside of the vehicle and the outside of the vehicle, and then positioned upwards to gain access to the SCDS. - When the intermediate steering shaft is disconnected, the steering wheel must be in the LOCK position to prevent damage to the clockspring. - During installation of the intermediate steering shaft, new bolts must be installed. Tighten the bolts to 49 Nm (36 lb-ft). ^ On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield aside. ^ On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front wheel.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8818 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8819 9.

Tighten the bolts to 49 Nm (36 lb-ft). ^ On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield aside. ^ On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front wheel.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8862 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8863 9.

See Figure 1. Note that the revised SCDS has a different electrical connector. A jumper adapter (which is included in the parts kit) is required when replacing the old SCDS with the revised SCDS. SCDS Location In most late model year vehicles involved in this recall, the SCDS is located on the master cylinder. In early model year vehicles (1992-1998), the SCDS may be located on the master cylinder but is often found on a brake line distribution block or on the brake proportioning valve. If in doubt, just follow the metal brake lines from the master cylinder until the switch is found. ^ On early model year E-Series vehicles, the SCDS is located on the left frame rail. ^ On E-450 models only, remove the 3 screws and position the coolant degas bottle forward to allow access to the SCDS and servo. ^ On F-53 vehicles, if the SCDS is not located on the master cylinder, it may be located in a brake line junction block approximately 457 mm (18 in) below the master cylinder. It may be necessary to reposition wiring harnesses and/or remove add-on equipment in order to locate the switch. ^ On 1993 MARK VIII vehicles, the steering wheel intermediate shaft needs to be disconnected from the inside of the vehicle and the outside of the vehicle, and then positioned upwards to gain access to the SCDS. - When the intermediate steering shaft is disconnected, the steering wheel must be in the LOCK position to prevent damage to the clockspring. - During installation of the intermediate steering shaft, new bolts must be installed. Tighten the bolts to 49 Nm (36 lb-ft). ^ On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield aside. ^ On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front wheel.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8946 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > Recalls for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8947 9.

FUSED JUMPER HARNESS (FJH) INSTALLATION 1. Connect the fused jumper harness to the SCDS and the vehicle harness. 2. Secure the jumper harness to the existing harness with tie straps, making sure the fuse holders are positioned vertically with the cap facing upward. Wrap the tie straps underneath, then over the top of the existing harness and verify proper fuse holder orientation. See Figure 4. SPEED CONTROL DEACTIVATION SWITCH (SCDS) REPLACEMENT NOTE: The brake pedal must not be depressed during the removal and replacement of the SCDS. 1. Check the brake fluid level at the master cylinder and, if necessary, fill to maximum fluid level. NOTICE: DO NOT apply fluid to the electrical connector or damage to the connector may occur. NOTICE: The 1994 Capri Brake Repair Kit contains a brass sealing washer. Install the brass washer onto the SCDS before installing it on the vehicle. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8990 2. Add a few drops of Motorcraft High Performance DOT 3 Motor Vehicle Brake Fluid, PM1-1 or PM-1-C (US), CPM-1-C (Canada), to the fluid port at the threaded end of the new SCDS. See Figure 5. NOTICE: Do not allow any foreign material to enter the master cylinder port once the SCDS is removed. NOTE: Call the Special Service Support Center for assistance if brake fluid does not flow from the SCDS fitting when the SCDS is removed. NOTE: If the new SCDS is not installed immediately after the original switch is removed, the master cylinder brake fluid could drop below the minimum level and air could enter the brake system. If this should occur, air must be bled from the brake system at all 4 wheels. In this situation, the labor to bleed the brake system will not be covered under this program. 3. Remove the SCDS. 4. With the brake fluid reservoir cap removed, observe for brake fluid dripping/draining from the SCDS fitting. As soon as brake fluid begins to bleed from the fitting, install the new SCDS. 5. Tighten the new SCDS as follows: ^ 18 Nm (159 lb-in) - all vehicles except 1994 Capri. ^ 13 Nm (115 lb-in) - 1994 Capri. 6. Check the brake fluid level at the master cylinder, fill to maximum fluid level and install the brake fluid reservoir cap. 7. Disconnect the speed control servo and inspect the vehicle harness connector for heat damage. See Figure 6. ^ If no heat damage is found at the speed control servo connector (even if there is presence of brake fluid in the connector), proceed to the next step. ^ If the speed control servo connector is heat damaged, call the Special Service Support Center for further instructions. 8. With the speed control servo disconnected, use shop air only to blow the SCDS harness electrical connector and the servo connector dry of any trace of brake fluid. Do not use any type of solvent to clean the connectors. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Cruise Control > Sensors and Switches - Cruise Control > Brake Switch (Cruise Control) > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Brake Switch (Cruise Control): > 05S28S15 > Apr > 08 > Recall - Cruise Control Deactivation Switch Inspection > Page 8991 9. Cut approximately 3 mm (1/8 in) off the grease tube applicator tip. 10. Before installing the jumper harness, fill the vehicle harness end of the jumper (male pin connector end) with Motorcraft Electrical Grease II XG-15-A. See Figure 7. 11. Install the adapter jumper harness by connecting it to both the SCDS and the vehicle harness. Using the provided tie strap, secure the jumper harness to a nearby component such as the speed control cable or another wire harness. NOTICE: Be sure to apply and adequate amount of grease to the vehicle harness connector only. DO NOT apply the grease directly to the connector of the servo module. 12. Apply a 5 mm (3/16 in) high bead of Motorcraft Electrical Grease II XG-15-A across the entire width and length of the servo vehicle harness connector.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9068 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9069 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9070 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9071 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9072 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9073 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9074 Audible Warning Device: Electrical Diagrams Diagram 66-1 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Diagram Information and Instructions > Page 9075 Diagram 66-2 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Page 9076 Audible Warning Device: Description and Operation The warning device system consists of the following: ^ safety belt warning lamp switch ^ door ajar switch ^ Generic Electronic Module (GEM) ^ key-in-ignition warning switch ^ headlamp on warning ^ low washer fluid warning Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Diagrams > Page 9077 Audible Warning Device: Testing and Inspection For further information regarding the diagnosis of this component and the system that is a part of, please refer to Instrument Panel, Gauges and Warning Indicators; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Service and Repair > Door Ajar Switch Audible Warning Device: Service and Repair Door Ajar Switch For additional information, refer to Power Locks. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component Information > Service and Repair > Door Ajar Switch > Page 9080 Audible Warning Device: Service and Repair Key In Ignition Warning Switch REMOVAL 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 9116 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 9117 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 9118 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure.

This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. 1. Turn all vehicle accessories OFF. 2. Turn the ignition switch to OFF. 3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB. For additional information, refer to the Wiring Diagram Manual. 4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding. 5. Turn the ignition OFF. Warning: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. The side impact sensors (if equipped) are located at or near the base of the B-pillars. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). 6. Disconnect the battery ground cable (14301) and wait at least one minute. Repowering Procedure Warning: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards. 1.

This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool. Deactivation and Reactivation Supplemental Restraint System ( SRS ) Deactivation and Reactivation Special Tool(s) Deactivation Warning: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. Warning: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. Warning: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. Warning: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. Warning: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Warning: To reduce the risk of personal injury, do not use any memory saver devices. Note: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. Note: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault. Note: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. All Vehicles 1. Move and tilt the front seats to their highest and most forward position. 2. Turn all vehicle accessories OFF. 3. Turn the ignition switch to OFF. 4. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F22 (10A) from the CJB.

This is commonly known as the On Board Diagnostic System (OBD II). This OBD II system protects the environment by ensuring that your vehicle continues to meet government emission standards. The OBD II system also assists the service technician in properly servicing your vehicle. The SERVICE ENGINE SOON indicator light illuminates when the ignition is first turned to the ON position to check the bulb. If it comes on after the engine is started, on of the engine's emission control systems may be malfunctioning. The light may illuminate without a driveability concern being noted. The vehicle will ususally be drivable and will not require towing. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Maintenance Required Lamp/Indicator > Component Information > Description and Operation > Page 9259 Maintenance Required Lamp/Indicator: Service and Repair Solid SERVICE ENGINE SOON light This means that the On Board Diagnostic System (OBD II) has detected a malfunction. Temporary malfunctions may cause your SERVICE ENGINE SOON light to illuminate. Examples are: 1. The vehicle has run out of fuel. (The engine may misfire or run poorly.) 2. Poor fuel quality or water in the fuel. 3. The fuel cap may not have been properly installed and securely tightened. The temporary malfunctions can be corrected by filling the fuel tank with good quality fuel and/or properly installing and securely tightening the gas cap. After three driving cycles with out these or any other temporary malfunctions present, the SERVICE ENGINE SOON light should turn off. (A driving cycle consists of a cold engine start-up followed by mixed city/highway driving.) No additional vehicle service is required. Blinking SERVICE ENGINE SOON light Engine misfire is occurring which could cause damage to your catalytic converter. You should drive in a moderate fashion (avoid heavy acceleration and deceleration) and have your vehicle serviced at the first available opportunity. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Malfunction Indicator Lamp > Component Information > Description and Operation Malfunction Indicator Lamp: Description and Operation Malfunction Indicator Lamp (MIL) Schematic CHECK ENGINE, SERVICE ENGINE SOON, or ISO Standard Engine Symbol The Malfunction Indicator Lamp (MIL) alerts the driver that the Powertrain Control Module (PCM) has detected an On Board Diagnostic (OBD) II emission-related component or system fault. When this occurs, an OBD II Diagnostic Trouble Code (DTC) will be set. ^ The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON or ISO standard engine symbol. ^ Power is supplied to the MIL whenever the ignition switch is in the RUN or START position. ^ The MIL will remain on in the RUN/START mode as a bulb check during the instrument cluster proveout for approximately 4 seconds. ^ If the MIL remains on after the bulb check: The PCM illuminates the MIL for an emission related concern and a DTC will be present. - The instrument cluster will illuminate the MIL if the PCM does not send a control message to the instrument cluster. - The PCM is operating in the Hardware Limited Operation Strategy (HLOS). - The MIL circuit is shorted to ground. ^ If the MIL remains off (during the bulb check): Bulb is damaged. - MIL circuit is open. ^ To turn off the MIL after a repair, a reset command from the Scan Tool must be sent, or three consecutive drive cycles must be completed without a fault. ^ For any MIL concern Symptom Charts. ^ If the MIL blinks at a steady rate, a severe misfire condition could possibly exist. ^ If the MIL blinks erratically, an intermittent open B+ to the bulb or an intermittent short to ground in the MIL circuit exist.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9285 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9286 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9287 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9288 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9289 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Audible Warning Device Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 9290 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Fuel Gauge Module > Component Information > Testing and Inspection Fuel Gauge Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that is a part of, please refer to Instrument Panel, Gauges and Warning Indicators; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Instrument Panel Control Module > Component Information > Technical Service Bulletins > Customer Interest for Instrument Panel Control Module: > 02-23-4 > Nov > 02 > Engine Controls - DTC P1635 Set After PCM/IC Replacement Technical Service Bulletin # 02-23-4 Date: 021125 Engine Controls - DTC P1635 Set After PCM/IC Replacement Article No. 02-23-4 11/25/02 ^ DIAGNOSTIC TROUBLE CODE (DTC) - P1635 AND/OR P1639 PRESENT AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT GASOLINE ENGINE VEHICLES ONLY ^ LAMP - 4X4 LAMP ILLUMINATED AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT - GASOLINE ENGINE VEHICLES ONLY ^ SPEEDOMETER - INACCURATE AND/OR INOPERATIVE AFTER POWERTRAIN CONTROL MODULE (PCM) OR INSTRUMENT CLUSTER REPLACEMENT - GASOLINE ENGINE VEHICLES ONLY FORD: 1999-2002 MUSTANG 2000-2002 FOCUS 1999-2002 EXPEDITION, F-150 2000-2002 E SERIES 2001-2002 EXPLORER SPORT TRAC, EXPLORER SPORT, RANGER 2002 EXPLORER LINCOLN: 1999-2002 TOWN CAR, NAVIGATOR 2002 BLACKWOOD MERCURY: 2002 MOUNTAINEER Article 02-5-8 is being republished in its entirety to update the Service Procedure and to clarify build dates for Explorer.

In the event either code is set, use one of the following NGS Procedures "B" or "C" or WDS Procedure "D" to ensure the PCM is properly configured. NOTE THE FOLLOWING NGS PROCEDURES MUST BE PERFORMED USING THE NGS FLASH CABLE. Procedure A - NGS PREFERRED Method To Prevent P1635/P1639 1. With the original PCM installed and using the NGS service card, select "Programmable Module Installation". 2. Select PCM from the module list. 3. Select "Retrieve Module Config-Old ECU". 4. After the Module data has been stored, install the new PCM, press CANCEL to return to the menu and select "Restore Module Config-New ECU". This procedure will retrieve the VID data from the original PCM and store it into the new PCM. If the original PCM will not communicate, install the new PCM and start the procedure over at Step 1. If the new PCM VID is blank, the NGS will direct you to contact the As-Built Data center during Step a above. Obtain As-Built Data from the Professional Technician Society (PTS) website and manually enter the PCM data from the As-Built Data sheet as the NGS asks for it. After the data has been entered, continue to Step 4 above. Procedure B - NGS Alternative Method 1. Using NGS service card, select "Service Bay Functions". 2. Select PCM from the module list. 3. Select "Module Configuration". 4. Select "94-02 EECV & PTEC-By TSB". 5. Cycle ignition as directed by NGS. 6. Once the PCM initializes and the warning screen is displayed, Tire size/Axle, etc. can then be updated. Procedure C - If the VID block is not correctly programmed - but has some data stored in it, the NGS Service Function Card may not be able to configure the PCM due to the need to reprogram the module 1. Create an NGS Flash Card with the correct calibration (Tear Tag). 2. Start the reprogramming process. (you will be notified that the vehicle already has the latest calibration). 3. Select CANCEL - you will be given the opportunity to update PCM parameters (Vehicle ID block data). 4. Update the Vehicle ID block data and, it necessary, the NGS will continue to reflash the module.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9411 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9412 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9413 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9414 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9415 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9416 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9417 Brake Lamp: Electrical Diagrams For further information regarding this component please refer to: Lighting and Horns/Diagrams. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview Brake Lamp: Initial Inspection and Diagnostic Overview 1.

On most applications the BPP switch is hard wired to the PCM and supplies battery positive voltage (B+) when the vehicle brake pedal is applied. On other applications the BPP switch signal is broadcast over the SCP link via another module to be received by the PCM. On applications where the BPP switch is hard wired to the PCM and stoplamp circuit, if all stoplamp bulbs are burned out (open), high voltage is present at the PCM due to a pull-up resistor in the PCM. This provides fail-safe operation in the event the circuit to the stoplamp bulbs has failed. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Brake Light Switch > Component Information > Diagrams > Page 9429 Brake Light Switch: Service and Repair REMOVAL 1.

ISSUE Corporate, municipal, or police fleets may have had their Ford Motor Company vehicle modified to flash the brake lamps whenever the "police lights" or other aftermarket lights are turned on. These added "police lights" have the potential to disable the brake shift interlock system. The brake shift interlock feature prevents the vehicle from being shifted from park unless the brake pedal is depressed. Disabling of the brake shift interlock feature may enable the operator to inadvertently apply the accelerator instead of the brake pedal when shifting from Park to Drive or Reverse gears. ACTION As appropriate, dealers should advise owners (including corporate, municipal, and police agencies) that any vehicle that has been modified with a connection to the brake circuit, or that electrically interfaces with the brake lamps in that manner, should be disconnected IMMEDIATELY and the emergency lighting system should be modified in a manner that does not interfere with normal service operation or the brake shift interlock. In addition, if the high-mount stoplamp flashes when the "police lights" are on, the modification does not conform with the Federal Motor Vehicle Safety Standards Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > High Mounted Stoplamp <--> [Center Mounted Brake Lamp] > Component Information > Technical Service Bulletins > All Technical Service Bulletins for High Mounted Stoplamp: > 02-17-6 > Sep > 02 > A/T - Inadvertent Shift Interlock Disabling > Page 9444 (FMVSS) 108 which requires that the high-mount stoplamp only illuminate when applying the brakes. Installation of warning lights should only be performed with a completely separate electrical system, without connection to any existing vehicle wiring.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points.

CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9625 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9626 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9739 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9740 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9741 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9742 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9743 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 9744 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Illuminated Entry Module <--> [Interior Lighting Module] > Component Information > Diagrams > Page 9745 Illuminated Entry Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Lighting and Horns; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Relay > Component Information > Locations Interior Lighting Relay: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Relay > Component Information > Locations > Page 9749 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Relay > Component Information > Locations > Page 9750 The interior lamp relay is located in the central junction box under the left side of the instrument panel. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Relay > Component Information > Locations > Page 9751 Interior Lighting Relay: Testing and Inspection Console Blower Relay Component Testing Procedure Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Parking Lamp Relay > Component Information > Locations Parking Lamp Relay: Locations Located in the RPO Relay Block #1, which is located in the dash, above the passenger air bag. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Parking Lamp Relay > Component Information > Locations > Page 9755 Parking Lamp Relay: Testing and Inspection Console Blower Relay Component Testing Procedure Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Reversing Lamp Switch <--> [Backup Lamp Switch] > Component Information > Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Reversing Lamp Switch <--> [Backup Lamp Switch] > Component Information > Diagrams > 4R70W Transmission Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Reversing Lamp Switch <--> [Backup Lamp Switch] > Component Information > Diagrams > 4R70W Transmission > Page 9762 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Diagrams > Page 9766 Brake Light Switch: Description and Operation Brake Pedal Position Switch Typical Brake Pedal Position Switch The Brake Pedal Position (BPP) switch is used by the PCM to disengage the transmission torque converter clutch and on some applications as an input to the idle speed control for idle quality. On most applications the BPP switch is hard wired to the PCM and supplies battery positive voltage (B+) when the vehicle brake pedal is applied. On other applications the BPP switch signal is broadcast over the SCP link via another module to be received by the PCM. On applications where the BPP switch is hard wired to the PCM and stoplamp circuit, if all stoplamp bulbs are burned out (open), high voltage is present at the PCM due to a pull-up resistor in the PCM. This provides fail-safe operation in the event the circuit to the stoplamp bulbs has failed. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Diagrams > Page 9767 Brake Light Switch: Service and Repair REMOVAL 1.

If certain components of the system are removed, some of the refrigerant oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part. 1. Rotate the A/C compressor shaft six to eight revolutions while collecting oil in a clean measuring device. ^ If the amount of oil drained from the old A/C compressor is between 85 - 142 ml (3 - 5 ounces), pour the same amount plus 30 ml (1 ounce) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor. ^ If the amount of oil that was removed from the old A/C compressor is greater than 142 ml (5 ounces), pour the same amount drained of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor. ^ If the amount of oil that was removed from the old A/C compressor is less than 85 ml (3 ounces), pour 85 ml (3 ounces) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B into the new A/C compressor. NOTE: Service A/C compressors are shipped without compressor oil. 2. For the suction accumulator/drier, drill two 1/2 inch holes in the suction accumulator/drier cylinder and drain the oil into a calibrated container. 1 Add a quantity of new oil to match that drained from the old suction accumulator/drier plus 60 ml (2 ounces) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B. 3. For the A/C evaporator core, add 89 ml (3 ounces) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B to the suction accumulator/drier inlet tube. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Multifunction Switch <--> [Combination Switch] > Component Information > Component Information > Specifications > Page 9821 4. For the A/C condenser core, add 30 ml (1 ounce) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B to the A/C condenser core or the suction accumulator/drier inlet tube. 5. Add 60 ml (2 ounces) of clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B to the suction accumulator/drier inlet tube when performing each of the following repairs: ^ replacement of the A/C evaporator core orifice ^ replacement of the A/C compressor pressure relief valve ^ replacement of a refrigerant line ^ repair of an O-ring seal leak ^ repair of a charge port leak 6. Installation of new components that do not require discharge of refrigerant and resulting oil loss, such as the A/C cycling switch and the A/C pressure transducer, do not require additional oil. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Door Switch > Component Information > Service and Repair Door Switch: Service and Repair For additional information, refer to Body and Frame; Doors, Hood and Trunk. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Hazard Warning Switch > Component Information > Diagrams Hazard Warning Switch: Diagrams For further information regarding this component please refer to: Lighting and Horns/Diagrams. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Hazard Warning Switch > Component Information > Diagrams > Page 9828 Hazard Warning Switch: Description and Operation The steering column switches consist of the: ^ multifunction switch, which controls the: ^ turn signal. ^ hazard flasher. ^ windshield wiper/washer. ^ rear wiper/washer. ^ headlamp dimmer/flash-to-pass. ^ ignition switch. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Hazard Warning Switch > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview Hazard Warning Switch: Initial Inspection and Diagnostic Overview 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9977 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9978 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9979 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9980 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9981 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9982 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9983 Tail Lamp: Electrical Diagrams For further information regarding this component please refer to: Lighting and Horns/Diagrams. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Page 9984 Tail Lamp: Testing and Inspection For further information regarding the diagnosis of this component and the system that it is part of, please refer to Parking Lamp; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Page 9985 Tail Lamp: Service and Repair REMOVAL 1.

The PCM provides a 5-volt reference (VREF) signal to the CPP switch and/or a Park/Neutral Position (PNP) switch (on the CPP signal line). If the CPP switch (either or both CPP and PNP switches are closed) is closed, indicating the clutch pedal is engaged and the shift lever is in the NEUTRAL position, the output voltage (5 volts) from the PCM is grounded through the signal return line to the PCM, and there is 1 volt or less. One volt or less indicates there is a reduced load on the engine. If the CPP switch (or PNP switch on vehicle or both CPP and PNP switches open on the vehicle) is open, meaning the clutch pedal is disengaged (all systems) and the shift lever is not in NEUTRAL position (PNP switch systems), the input on the CPP signal to the PCM will be approximately 5 volts. Then, the 5-volt signal input at the PCM will indicate a load on the engine. The PCM uses the load information in mass air flow and fuel calculations. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Lighting and Horns > Turn Signals > Multifunction Switch <--> [Combination Switch] > Component Information > Component Information > Diagrams > Page 10061 Digital Transmission Range Sensor: Service and Repair Special Tools 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10132 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10133 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10134 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10135 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10136 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10137 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Control Module > Component Information > Diagrams > Page 10138 Heated Glass Control Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Windows; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Element Relay > Component Information > Locations Heated Glass Element Relay: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Element Relay > Component Information > Locations > Page 10142 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Element Relay > Component Information > Locations > Page 10143 Heated Glass Element Relay: Testing and Inspection Component Testing Procedure Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Element Switch > Component Information > Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Heated Glass Element > Heated Glass Element Switch > Component Information > Diagrams > Page 10147 Heated Glass Element Switch: Service and Repair REMOVAL 1.

ISSUE Some vehicles may exhibit inoperative electric rear window defroster (heated back lite) grid lines, integral antenna concerns causing radio reception issues or terminal tabs pulled from the rear window glass. ACTION Follow the diagnostic and repair procedures included in this article to inspect and service rear defroster grid lines, integral antenna concerns or broken terminal tabs. SERVICE PROCEDURE Warrantable/Non Warrantable repairs Warrantable grid line repairs typically can be identified by one inoperative grid line with a small discoloration at the area of concern, approximately the size of a pinhead. Grid line(s) that are scratched or have the silver material removed are not warrantable and should be addressed with the customer. Replacement of backglass for grid line or bus bar tarnishing is not a warrantable repair. Tarnishing of the silver lines or bus bars is a normal condition. Please refer to the Heated Back Lite Damageability Job Aid for additional information and examples of defects and damage. NOTE THE GRID LINE MATERIAL IS NOT EMBEDDED INTO THE GLASS BUT IS BAKED TO THE GLASS SURFACE AND CONSEQUENTLY CAN BE SCRAPED OFF. INOPERATIVE LINES MAY APPEAR TO THE EYE TO BE UNDAMAGED DUE TO RESIDUE REMAINING ON Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Rear Defogger > Component Information > Technical Service Bulletins > A/C/Audio - Defroster/Antenna Grid Diagnosis/Repair > Page 10153 THE GLASS AND WILL REQUIRE DIAGNOSIS WITH A VOLTMETER OR 12V TEST LAMP AS EXPLAINED IN THIS ARTICLE. Examples Of Non-Warrantable Grid Line Damage ^ Ice scraper damage to grid lines ^ Animal scratches on grid lines ^ Window tint film/removal of the film which damages grid lines ^ Stickers placed over grids which upon removal, removes the grid line material ^ License plate (steel type placed against the inside of back glass) which rubs on the grid line causing damage ^ Temporary license plate (paper stuck on to the inside of the back glass) which upon removal removes grid line material ^ Cargo or lumber rubbing against the glass which removes grid line material ^ Cellular phone antenna installation/removal which damages grid line material NOTE AN UNDAMAGED GRIDLINE WILL HAVE SMALL RIDGES THAT PROJECT ABOVE THE SURFACE OF THE GLASS AND CAN EASILY BE FELT WHEN RUNNING A FINGERNAIL ACROSS THEM. GRIDLINES THAT HAVE BEEN "RAZOR BLADED" WILL FEEL SMOOTH WHEN A FINGERNAIL IS DRAGGED ACROSS THE AFFECTED AREA. THERE MAY BE SOME RESIDUE LEFT ON THE GLASS THAT APPEARS TO BE GRID MATERIAL BUT A CHECK WITH A VOLTMETER OR 12V TEST LAMP, AS EXPLAINED IN THIS ARTICLE, WILL CONFIRM AN OPEN CIRCUIT. GRID LINE INOPERATIVE - DIAGNOSTICS 1. Reference Workshop Manual Section 501-11 and the Wiring Diagram Section 56 to verify power and ground to the back-glass. 2. Connect a test lamp or DVOM to a good body ground. 3. Turn the ignition key to the run position and depress and release the rear defroster button to turn the system on. THE GRID IS ENERGIZED FOR APPROXIMATELY 10 MINUTES EACH TIME THE DEFROSTER BUTTON IS PRESSED. 4. Starting from the top grid line at the center of the back-glass, touch the test lamp or DVOM + lead to each grid line. (Use caution not to damage grid lines). The DVOM should read approximately 1/2 of the battery voltage on each line at the center of the back-glass. If using a test light, the bulb should be approximately the same brightness on each line from top to bottom. If the DVOM or light indicates a high voltage or no voltage on any grid line, move along the concern grid line with the + test lead or test lamp until the voltage changes suddenly. This is the area of concern, use chalk to mark the area of concern and mark the outside of the glass at that same area. 5. Repair per the Grid Line Repair Procedure. GRID LINE REPAIR PROCEDURE NOTE LONG GAPS ARE ALMOST ALWAYS DUE TO DAMAGE AND ARE NOT WARRANTABLE, HOWEVER THEY CAN BE REPAIRED. THE LONGER THE GAP THE MORE IMPORTANT IT IS TO APPLY A MINIMUM SIX (6) COATS OF CONDUCTIVE REPAIR MATERIAL WITH THE FIVE (5) MINUTE DRY TIME BETWEEN EACH COAT. APPLYING LESS COATS OR NOT ALLOWING DRY TIME BETWEEN COATS WILL PRODUCE REPAIRED RESISTANCE THAT IS GREATER THAN OEM RESISTANCE, RESULTING IN POOR DEFROST PERFORMANCE AND EXCESSIVE LOCALIZED HEATING. REPAIRED LONG GAPS ARE GENERALLY NOT VISUALLY PLEASING UNLESS EXTREME CARE IS TAKEN WHEN TAPING AFFECTED GRID LINE AREAS. NOTE IF THE BROWN COLOR UNDER THE GRID LINE IS DAMAGED OR MISSING (THIS IS VERY RARE), IT WILL BE NECESSARY TO APPLY BROWN ACRYLIC LACQUER TOUCH-UP PAINT FOR COLOR MATCH. THIS PAINT MUST MEET SPECIFICATION ESR-M2P100-C AND SHOULD BE APPLIED TO THE GLASS PRIOR TO APPLYING THE REAR WINDOW DEFROSTER REPAIR COMPOUND. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Rear Defogger > Component Information > Technical Service Bulletins > A/C/Audio - Defroster/Antenna Grid Diagnosis/Repair > Page 10154 Service inoperative grid lines on rear window glass using Motorcraft Defroster Repair PM-11 or equivalent meeting Ford specification ESB-M4J58-A as follows: Surface Preparation 1. Bring vehicle inside and warm it to 60° F (16° C) or above. 2. Do not use scrapers, sharp instruments, or abrasive window cleaners on the interior surface of the rear window glass as this may cause damage to the grid lines. Clean the entire grid line service area with Ultra Clear Spray Glass Cleaner ZC-23 or equivalent meeting Ford specification ESR-M14P5-A to remove all dirt, wax, grease, oil or other foreign matter. It is important that the repair area be clean and dry. NOTE THE REPAIR AREA HOWEVER SHOULD BE CLEANED WITH STEEL WOOL OR AN ABRASIVE PAD SUCH AS SCOTCHBRITE TO REMOVE GRIME. Mixing The bottle of Rear Window Defroster Repair compound and touch-up paint (if needed) must be at room temperature. Shake the bottle for at least one (1) minute for thorough mixing. Shake frequently during use. Application 1. Mark location of open grid on the outside of the back window glass (performed in diagnostics). Place protective covering over the package tray as necessary. 2. Using "fine line tape", mask off the area directly above and below open grid line (Figure 1). It is best to extend the tape 26 mm (1") beyond the concern area in both directions. The open should be at the center of the mask and tape gap must be no wider than the existing grid line. Other types of tape may be used but end results of the repair may not appear as visually acceptable due to ease of application and tape edge finish. 3. If the brown layer of the grid is not broken or missing, apply only the silver grid repair compound to the open grid line. Apply the correct coating in several smooth continuous strokes (allowing five (5) minutes drying time between coats) across the open grid line area using the brush applicator in the cap. Extend the service coating at least 6 mm (.25") on both sides of the open grid line area. Apply a minimum of six (6) coats of the grid repair compound. 4. If both brown and silver layers of the grid are broken or missing, apply a coating of brown lacquer touch-up paint across the open line area first. Take care to paint only the area missing the color. Two (2) coats may be necessary to obtain the proper color. Allow the touch-up paint to dry at least five (5) minutes between coats. Apply six (6) coats of grid repair compound. NOTE THE INTERIOR SIDE OF THE GRID LINES ARE NOT PAINTED, BUT DUE TO THE SILVER TARNISHING WILL TEND TO CHANGE THE GRID TO A GOLD OR BROWN COLOR. THE REPAIRED AREA WILL BE BRIGHT SILVER AND WILL ALSO TARNISH OVER Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Rear Defogger > Component Information > Technical Service Bulletins > A/C/Audio - Defroster/Antenna Grid Diagnosis/Repair > Page 10155 TIME TO MATCH THE REST OF THE GRID. 5. After five (5) minutes of dry time of the final coat of grid repair compound, remove the tape, step outside and inspect the repaired area. If the repair compound is visible above or below the grid, the excess can be removed. This may be done by placing a single-edge razor blade on the back window glass parallel to grid and scrape gently toward grid. A wider/thicker line will perform better but may not be cosmetically appealing. CAUTION BE CAREFUL NOT TO DAMAGE GRID LINE WITH RAZOR BLADE. VERIFY ALL OF THE GRID LINES FUNCTION PROPERLY WHEN FINISHED. Curing The service coating will air-dry in approximately one (1) minute and the system can be energized after five minutes. Maximum hardness and adhesion occur after approximately 24 hours. SOLDER METHOD OF LEAD TERMINAL NOTE THE REAR WINDOW MUST BE AT A MINIMUM OF 60° F (16° C) BEFORE A REPAIR IS MADE. PLACE PROTECTIVE COVERING OVER THE PACKAGE TRAY AS NECESSARY. The new terminal will cover the original terminal location, but must be placed so that the new terminal conductive areas will be placed on a good conductive base. This area should be cleaned with steel wool or an abrasive pad to remove grime from the buss-bar. The area should then be cleaned with Ultra Clear Spray Glass Cleaner, ZC-23, or equivalent meeting Ford specification ESR-M14P5-A to remove all dirt, wax, grease, oil or other foreign matter. It is important that the repair area be clean and dry and appear metallic. Depending on the buss-bar condition, rigorous polishing with steel wool may be required. Please note that the entire buss-bar may be cleaned to improve appearance. CAUTION DO NOT USE ANY TYPE OF FLAME TORCH OR FLAME HEATED SOLDERING GUN FOR THIS PROCEDURE. TESTING INDICATED INADEQUATE HEAT GENERATION AT THE TIP AND THE EXHAUST HEAT CAN CAUSE DAMAGE TO PLASTIC TRIM PARTS IN THE AREA. USE ONLY AN ELECTRIC SOLDERING GUN WITH 100 WATTS OR MORE OF POWER. BEFORE USING THE SOLDERING GUN, BE SURE TO MELT A SMALL AMOUNT OF ROSIN CORE SOLDER TO THE TIP. THE SOLDER WILL ASSIST IN ACHIEVING BETTER HEAT TRANSFER FROM THE SOLDERING GUN TIP TO THE NEW TERMINAL. The new terminal has pre-applied solder, flux and temperature sensitive paint. The paint provides a visual indication when the terminal has reached the proper temperature to melt the solder on the terminal. When the proper temperature is achieved the temperature paint will liquefy and change color. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Rear Defogger > Component Information > Technical Service Bulletins > A/C/Audio - Defroster/Antenna Grid Diagnosis/Repair > Page 10156 Use terminal type A (Figure 2) for all tab locations except on the Focus vehicle line. For the Focus, use type B (Figure 3). NOTE DEPENDING ON THE ORIGINAL TERMINAL LOCATION, AND WHETHER THE TERMINAL IS COVERED BY PILLAR TRIM, WILL DETERMINE WHERE TO LOCATE THE NEW TERMINAL. SOME GRID LINE BUSS-BARS MAY ONLY ALLOW THE PLACEMENT OF THE TERMINAL ABOVE OR BELOW THE ORIGINAL TAB LOCATION DUE TO SPACE LIMITATIONS, BUT FOR MOST VEHICLE APPLICATIONS THE REPLACEMENT TAB LOCATION WILL COVER THE ORIGINAL TAB LOCATION BUT STILL ALLOW THE REPLACEMENT TAB TO ATTACH TO THE BUSS-BAR ON GOOD CONDUCTIVE MATERIAL. 1. Place the replacement terminal over the original tab location making sure the conductive areas of the terminal will be on a good conductive area. Do not place the terminal tab foot on the original location which does not have conductive material (figure 4). 2. Hold the terminal in place with an item such as regular lead pencil at a 90 degree angle from the terminal. (Terminal type B can be held in place with tape.) (Holding at other than a 90 degree angle may allow the terminal to slip when the solder liquefies). 3. Place the soldering gun tip on the top of the terminal but not on the painted areas of the tab. Energize the soldering gun and watch for the painted area of the terminal to liquefy and change color. The paint should liquefy in approximately 25-45 seconds after heating. As soon as the paint color completely changes on either side of the terminal, de-energize the soldering gun and continue to hold the terminal in place with the soldering gun and pencil for an additional thirty (30) seconds. 4. Remove the soldering gun and pencil from the terminal. The terminal should be allowed to cool for another two (2) minutes before the wiring lead is attached to the terminal. 5. Attach the electrical lead connection to this terminal, turn on the rear defroster, and verify operation.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10171 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10172 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10173 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10174 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10175 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10176 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Control Module > Component Information > Diagrams > Page 10177 Heated Glass Control Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Windows; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations Heated Glass Element Relay: Locations Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations > Page 10181 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Heated Glass Element Relay > Component Information > Locations > Page 10182 Heated Glass Element Relay: Testing and Inspection Component Testing Procedure Terminals Schematic Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions Power Window Control Module: Diagram Information and Instructions How to Find and Use These Diagrams Diagrams are presented in three main categories: ^ Power Distribution Diagrams ^ System Diagrams ^ Grounds Diagrams Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10187 Diagram 13-7 (Sample Power Distribution Diagram Page) Power Distribution Diagrams Provide the circuit details of how the system diagrams are powered.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10195 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10196 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10197 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points.

Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Relays and Modules - Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10387 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Relays and Modules - Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10388 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10521 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10522 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10523 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10524 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10525 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10526 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Pump > Component Information > Service Precautions Windshield Washer Pump: Service Precautions CAUTION: Do not operate the windshield washer pump prior to filling the windshield washer reservoir. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Windshield Washer Pump > Component Information > Service Precautions > Page 10530 Windshield Washer Pump: Service and Repair REMOVAL 1.

Step 1. Verify the concern. ^ Operate the complete system to check the accuracy and completeness of the customer's complaint. Step 2. Narrow the concern. ^ Using the wiring diagrams, narrow down the possible causes and locations of the concern to pinpoint the exact cause. ^ Read the description notes at the components and study the wiring schematic. You should then know enough about the circuit operation to determine where to check for the trouble. Step 3. Test the suspected cause. ^ Use electrical test procedures to find the specific cause of the symptoms. ^ The component location reference bars and the pictures will help you find components. Component location information for connectors, diodes, resistors, splices and grounds can be found at Vehicle Locations. Step 4. Verify the cause. ^ Confirm that you have found the correct cause by connecting jumper wires and/or temporarily installing a known good component and operating the circuit. Step 5. Make the repair. ^ Repair or replace the inoperative component. Step 6. Verify the repair. ^ Operate the system as in Step 1 and check that your repair has removed all symptoms without creating any new symptoms. Some engine circuits may need special test equipment and special procedures. See Testing and Inspection for the specific component, system, or sub-system in question. NOTE: Most Ford testing and inspection procedures will be found at the system/sub-system level; only a few component tests are provided by OE. TROUBLESHOOTING TOOLS JUMPER WIRE This is a test lead used to connect two points of a circuit. A Jumper Wire can bypass an open to complete a circuit. WARNING: Never use a jumper wire across loads (motors,etc.) connected between hot and ground. This direct battery short may cause injury or fire. VOLTMETER A DC Voltmeter measures circuit voltage. Connect negative (- or black) lead to ground, and positive (+ or red) lead to voltage measuring point. OHMMETER An Ohmmeter shows the resistance between two connected points. TEST LAMP Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10606 A Test Light is a 12-volt bulb with two test leads. Uses: Voltage Check, Short Check. SELF-POWERED TEST LAMP The Self-Powered Test Lamp is a bulb, battery and set of test leads wired in series. When connected to two points of a continuous circuit, the bulb glows. Uses: Continuity Check, Ground Check. CAUTION: When using a self -powered test lamp or ohmmeter; be sure power is off in circuit during testing. Hot circuits can cause equipment damage and false readings. In an inoperative circuit with a switch in series with the load, jumper the terminals of the switch to power the load. If jumpering the terminals powers the circuit, the switch is inoperative. CONTINUITY CHECK (Locating open circuits) Connect one lead of Self-Powered Test Lamp or Ohmmeter to each end of circuit. Lamp will glow if circuit is closed. Switches and fuses can be checked in the same way. VOLTAGE CHECK Connect one lead of test lamp to a known good ground or the negative (-) battery terminal. Test for voltage by touching the other lead to the test Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10607 point. Bulb goes on when the test point has voltage. SHORT CHECK A fuse that repeatedly blows is usually caused by a short to ground. It's important to be able to locate such a short quickly. 1. Turn off everything powered through the fuse. 2. Disconnect other loads powered through the fuse: ^ Motors: disconnect motor connector (Connector C4). ^ Lights: remove bulbs. 3. Turn Ignition Switch to RUN (if necessary) to power fuse. 4. Connect one Test Lamp lead to hot end of blown fuse. Connect other lead to ground. Bulb should glow, showing power to fuse. This step is just a check to be sure you have power to the circuit) 5. Disconnect the test lamp lead that is connected to ground, and reconnect it to the load side of the fuse at the connector of the disconnected component. (Connect the test lamp lead to connector C4). ^ If the Test Lamp is off, the short is in the disconnected component. ^ If the Test Lamp goes on, the short is in the wiring. You must find the short by disconnecting the circuit connectors, one at a time, until the Test Lamp goes out. For example, with a ground at X, the bulb goes out when C1 or C2 is disconnected, but not after disconnecting C3. This means the short is between C2 and C3. GROUND CHECK Turn on power to the circuit. Perform a Voltage Check between the suspected inoperative ground and the frame. Any indicated voltage means that the ground is inoperative. Turn off power to the circuit. Connect one lead of a Self-Powered Test Lamp or Ohmmeter to the wire in question and the other lead to a known ground. If the bulb glows, the circuit ground is OK. DIAGRAMS These diagrams make it easy to identify common points in circuits. This knowledge can help narrow the concern to a specific area. For example, if several circuits fail at the same time, check for a common power or ground connection (see Power and Ground Distribution Diagrams). If part of a Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10608 circuit fails, check the connections between the part that works and the part that doesn't work. For example, if the lo beam headlamps work, but the high beams and the indicator lamp don't work, then power and ground paths must be good. Since the dimmer switch is the component that switches this power to the high beam lights and indicator, it is most likely the cause of failure. TROUBLESHOOTING WIRING HARNESS AND CONNECTOR HIDDEN CONCERNS The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the PCM, utilize gold plated terminals in their connections to the wiring harness. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10609 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10610 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 10611 Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Control Module > Component Information > Diagrams > Page 10612 Wiper Control Module: Testing and Inspection Testing and Inspection For further information regarding the diagnosis of this component and the system that it is a part of, please refer to Wiper and Washer Systems; Testing and Inspection. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Technical Service Bulletins > Recalls for Wiper Motor: > NHTSA01V258000 > Aug > 01 > Recall 01V258000: Wiper Motor Gear Case Cover Wiper Motor: Recalls Recall 01V258000: Wiper Motor Gear Case Cover Vehicle Description: Passenger cars, sport utility vehicles, and light and medium duty pickup trucks.

Failure to follow this caution may result in damage to the motor magnets and will make the wiper motor inoperative. Rough handling of new replacement wiper motors may also damage the motor magnets. Use Alternator, Regulator, Battery and Starter Tester (ARBST) to test the wiper motor on the vehicle. To test the wiper motor, disconnect the windshield wiper mounting arm and pivot shaft from the windshield wiper motor; refer to Pivot Arm-Front or Pivot Arm-Rear. Disconnect the wiper motor. Connect the (1) green lead from (2) Alternator, Regulator, Battery and Starter Tester (ARBST) to the battery negative (-) post. Connect the (3) red lead from ARBST to the wiper motor (4) common brush terminal (terminal 3). Test the low speed mode by connecting a (5) cable from the battery positive (+) post to the (6) low speed brush terminal (terminal 4) and measure the current draw. If the current draw is greater than 3.5 amperes, replace the windshield wiper motor. Test the high speed mode by connecting a cable from the battery positive (+) post to the (7) high speed brush terminal (terminal 5) and measure the current draw. If the current draw is greater than 5.5 amperes, replace the wiper motor. Ford Expedition 2wd Workshop Manual (V8-4.6L SOHC VIN W (2000)) Ford Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Service and Repair > Windshield Wiper Wiper Motor: Service and Repair Windshield Wiper REMOVAL 1.
