Turn the keyswitch to the OFF position.
Check the connectors and the harness for the following problems:
Damage
Abrasion
Corrosion
Incorrect attachment
Refer to Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires in the harness that are associated with the throttle demand sensor. Check the wire connectors at the following positions:
ECM
Pressure sensorsThe wire connectors are shown in table 1.
Check the screws for the ECM connectors for the correct torque of 5.0 N m (44 lb in). Expected Result:The connectors and the harness should be free of the following faults: damage, abrasion, corrosion and incorrect attachment.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Repair the connectors or the harness and/or replace the connectors or the harness.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position.
Use the electronic service tool in order to monitor the diagnostic codes. Check and record any active diagnostic codes. Note: Wait at least 15 seconds in order for the diagnostic codes to become active.Expected Result:One of the following diagnostic codes is active:
0262-03 5 Volt Sensor DC Power Supply voltage above normal
0262-04 5 Volt Sensor DC Power Supply voltage below normalResults:
OK - Diagnostic code 0262-04 is active. Proceed to Test Step 3.
OK - Diagnostic code 0262-03 is active. Proceed to Test Step 6.
Not OK - Diagnostic codes 0262-04 and 0262-03 are not active. Proceed to Test Step 4.Test Step 3. Disconnect the Sensors
Turn the keyswitch to the ON position.
Use the electronic service tool in order to monitor the diagnostic codes.
Disconnect the pressure sensors one at a time. Wait for 30 seconds after each of the sensors is disconnected. Note: Diagnostic code 0262-04 will become inactive when the sensor that caused the 5 Volt diagnostic code is disconnected.
Ensure that all the pressure sensors are disconnected. Expected Result:The 5 Volt diagnostic code is not active when all of the sensors are disconnected.Results:
OK - Diagnostic code 0262-04 is not active when all of the sensors are disconnected.Repair: Reconnect all of the sensors except the suspect sensor.Proceed to Test Step 4.
Not OK - Diagnostic code 0262-04 is still active.Repair: Leave all of the sensors disconnected.Proceed to Test Step 5.Test Step 4. Install a New Sensor
Remove the connector from the suspect sensor and install the connector on a replacement sensor. Do not install the replacement sensor on the engine.
Use the electronic service tool in order to monitor the diagnostic codes. Expected Result:Diagnostic codes 0262-03 and 0262-04 are not active.Results:
OK - The 5 Volt diagnostic code is not active.Repair: Use the electronic service tool in order to clear all logged diagnostic codes. Remove the suspect sensor and then install the replacement sensor. Install the connector on the sensor.Verify that the repair eliminates the fault.STOP
Not OK - The 5 Volt diagnostic code is still active.Repair: Do not use the new sensor.Proceed to Test Step 5.Test Step 5. Disconnect the ECM Connector and Check for Active Diagnostic Codes
