Checking the wiring harness

Faults in the control module female connector can be the cause of the DTC. Check the connector with respect to oxidation, depressed pins and pin clamping force.
Jiggle the wiring harness at several points to detect intermittent breaks or short circuits. Check also the connector for oxidation or loose pins.
