Thoroughly inspect the ECM connectors and the connectors for the suspect sensor. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the temperature sensors.
Check the allen head screw on each ECM connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the allen head screw on the customer connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and wiring for abrasions and for pinch points from each sensor to the ECM.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the electronic service tool to the service tool connector.
Turn the keyswitch to the ON position.
Monitor the active diagnostic code screen on the electronic service tool. Check and record any active diagnostic codes.Note: Wait at least 15 seconds in order for the diagnostic codes to become active.
Look for an 03 diagnostic code or an 04 diagnostic code.Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active.Repair: The problem may have been related to a faulty connection in the harness. Carefully reinspect the connectors and wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information.STOP
Not OK - An 03 diagnostic code is active at this time. Proceed to Test Step 3.
Not OK - An 04 diagnostic code is active at this time. Proceed to Test Step 6.Test Step 3. Check the Pull-up Voltage at the Sensor Connector
Disconnect the suspect sensor at the sensor connector.
Turn the keyswitch to the ON position.
Measure the voltage between terminal 1 (signal) and terminal 2 (sensor common) at the sensor connector.
Turn the keyswitch to the OFF position.Expected Result:The voltage is 5.5 0.5 VDC.Results:
OK - The voltage is 5.5 0.5 VDC. The correct pull-up voltage is present at the suspect sensor connector.Repair: The open circuit is in the sensor or the wire between the sensor and the sensor connector. Replace the sensor. Do not install the sensor in the engine. Verify that no diagnostic codes are active for the suspect sensor before permanently installing the sensor.STOP
Not OK - The voltage is not 5.5 0.5 VDC. Proceed to Test Step 4.Test Step 4. Check the Signal Wire for a Short Circuit
Turn the keyswitch to the OFF position.
Disconnect the P2 connector.
Measure the resistance between the terminal for the sensor signal wire at the
