 Accelerator Pedal or Lever Idle Validation Circuit
|
Circuit Description
The accelerator pedal or lever position sensor is attached to the accelerator pedal or lever. The accelerator pedal or lever position sensor sends a signal to the electronic control module (ECM) when the accelerator pedal or lever is depressed and released. The accelerator pedal or lever position circuit contains three wires: accelerator pedal or lever position supply, accelerator pedal or lever position return, and accelerator pedal or lever position signal. The switch return circuit for the on-idle and off-idle validation circuit is a shared return with other OEM switches.
Component Location
The accelerator pedal or lever position sensor is located on the accelerator pedal or lever.
Shop Talk
This fault is logged when both the on idle and off idle validation switches disagree with the accelerator pedal or lever position signal. Turning the keyswitch ON while partially depressing the accelerator pedal or lever can cause this fault code to go active. This fault will stay active until the pedal or lever is cycled through its full travel.
