SENSOR, Accelerator Pedal Position
DESCRIPTION
 |
The accelerator pedal and APPS (Accelerator Pedal Position Sensor) are serviced as a complete assembly including the bracket. Refer to Accelerator Pedal Removal and Installation procedures.
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.
