Signal Too Low - Permanent Fault

Checking Component And Wiring







Check cable between engine control module (ECM) #B9 (#B19) and accelerator pedal (AP) position sensor #6 for a short-circuit to ground according to Checking wiring and terminals. Permanent faults (under Related Tests and Information).

Check cable between engine control module (ECM) #B9 (#B19) and accelerator pedal (AP) position sensor #6 for an open-circuit according to Checking wiring and terminals. Permanent faults (under Related Tests and Information).

Remedy as necessary.
