ECM (1) J1/P1 connectors (2) J2/P2 connectors
Thoroughly inspect the J1/P1 ECM connector. Inspect all of the connectors that are associated with the circuit.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that is associated with the active diagnostic code.
Check the ECM connector (allen head screw) for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and wiring for abrasions and for pinch points from the sensors back 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:
