Checking The Connectors And Cables

Check the signal cable between engine control module (ECM) terminal #B26 (#C26) and accelerator pedal (AP) position sensor terminal #5 (cable harness side). Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.

HINT: With the ignition on, the power supply to the accelerator pedal (AP) position sensor must be approximately 12 V measured between accelerator pedal (AP) position sensor terminals #4 and #6 (cable harness side). 

Try a new accelerator pedal (AP) position sensor if no fault is found and the fault is permanent.

Remedy as necessary.
