Accelerator Pedal: Description and Operation
Accelerator Pedal Position (APP) Module
Description
The Accelerator Pedal Position (APP) module contains three potentiometers (a device for measuring an unknown voltage or potential difference by
comparison to a standard voltage). Each of the APP sensors send a varying voltage to the PCM. By monitoring the output voltage from the APP module,
the PCM can determine fuel delivery based on the accelerator pedal position (driver demand).
