Ignition off
Check the accelerator pedal position sensor and engine control module (ECM) connectors. Check for contact resistance. Check for oxidation.
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 ground.

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

Remedy as necessary.
