Accelerator Pedal Position Sensor
WARNING: This page is about a different variant/trim than selected.
The APP sensors are located on the accelerator pedal.
Accelerator pedal demand is communicated to the PCM by 2 potentiometers located in the APP sensor. The PCM uses the 2 signals to determine the position, rate of movement and direction of movement of the pedal.
The PCM supplies a 5V reference voltage and a ground for each potentiometer.
