Checking Wiring And Connectors







Check accelerator pedal (AP) position sensor for intermittent loose connections according to Checking wiring and terminals. Intermittent faults.

Check signal cable between engine control module (ECM) connector #B17 (#B29) and accelerator pedal (AP) position sensor #5 for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults.

Check signal cable between engine control module (ECM) connector #B17 (#B29) and accelerator pedal (AP) position sensor #5 for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults.

Remedy as necessary.
