Accelerator Pedal Position Sensor: Description and Operation
Operation

OPERATION

The Accelerator Pedal Position Sensor (APPS) is a linear potentiometer. It provides the Powertrain Control Module (PCM) with a DC voltage signal
proportional to the angle, or position of the accelerator pedal. The APPS signal is translated (along with other sensors) to place the throttle plate (within
the throttle body) to a pre-determined position.
