SENSOR-ACCELERATOR PEDAL POSITION
DESCRIPTION
The Accelerator Pedal Position Sensor (APPS) (6) is attached to the accelerator pedal assembly under the instrument panel.
The APPS is used only with the 5.7L V-8 engine. The 5.7L engine does not use a mechanical throttle cable.
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.
