P2 ECM connectorTest Step 1. Verify all Active Diagnostic Codes
Connect the electronic service tool to the service tool connector.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Monitor the "Active Diagnostic Codes" screen on the electronic service tool.Expected Result:There is an active diagnostic code for one or more of the temperature sensors.Results:
Yes - There is an active diagnostic code for one or more of the temperature sensors. Proceed to Test Step 2.
No - There are no active diagnostic codes for the temperature sensors.Repair: If there are logged diagnostic codes for one or more of the temperature sensors and the engine is not running properly, refer to Troubleshooting, "Troubleshooting without a Diagnostic Code". If the engine is running properly at this time, an intermittent condition may be causing the logged codes. Refer to Troubleshooting, "Electrical Connectors - Inspect". Stop.Test Step 2. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF/RESET position.
Thoroughly inspect the J2/P2 ECM connector, the suspect sensor connector, and any other connectors in the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the sensor connector and the ECM connector that are associated with the active diagnostic code.
Verify that the latch tab of the connector is properly latched.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasions and for pinch points from the 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 - Proceed to Test Step 3.
Not OK - 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. Stop.Test Step 3. Verify that the Diagnostic Code is Still Active
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic code.
Access the "Active Diagnostic Codes" screen on the electronic service tool and check for active diagnostic codes.
Determine if the problem is related to an open circuit diagnostic code 03 or a short circuit diagnostic code 04.Expected Result:A short circuit diagnostic code 04 or an open circuit diagnostic code 03 is active.Results:
Short Circuit - A short circuit diagnostic code 04 is active at this time. Proceed to Test Step 4.
Open Circuit - An open circuit diagnostic code 03 is active at this time. Proceed to Test Step 5.
No Active Diagnostic Codes - The problem seems to be resolved.Repair: Carefully reinspect the connectors and wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information. Stop.Test Step 4. Disconnect the Sensor in Order to Create an Open Circuit
Turn the keyswitch to the OFF/RESET position.
Disconnect the connector to the sensor with the short circuit diagnostic code 04.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Access the "Active Diagnostic Codes" screen on the electronic service tool and check for an active open circuit diagnostic code 03 for the suspect sensor.
Turn the keyswitch to the OFF/RESET position.Expected Result:An open circuit diagnostic code 03 is now active for the disconnected sensor.Results:
OK - A short circuit diagnostic code 04 was active before disconnecting the sensor. An open circuit diagnostic code 03 became active after disconnecting the sensor.Repair: Temporarily connect a new sensor to the harness, but do not install the new sensor in the engine. Check for a short circuit diagnostic code 04 while the new sensor is connected. If the short circuit diagnostic code 04 is not present, permanently install a new sensor. Clear any logged diagnostic codes.Verify that the repair eliminates the problem. Stop.
Not OK - The short circuit diagnostic code 04 is present. There is probably a short circuit between the sensor harness connector and the ECM. Disconnect the sensor. Proceed to Test Step 6.Test Step 5. Short the Sensor Connector
Turn the keyswitch to the OFF/RESET position.
Unplug the suspect sensor.
