Accelerator Pedal Position (APP) Sensor

The accelerator pedal position (APP) sensor is mounted on the accelerator pedal. The APP sensor detects the position of the accelerator pedal and inputs this information as a voltage to the powertrain control module (PCM). The PCM broadcasts the APP on the CAN bus. The transmission control module (TCM) reads APP off the CAN message. The PCM uses the APP sensor information to aid in determining shift scheduling and torque converter (TCC) control.
