Accelerator Pedal Position (APP) Sensor
Description
The Accelerator Pedal Position (APP) sensor is located inside the accelerator pedal. The accelerator pedal position
sensor cannot be disassembled by itself. The accelerator pedal must be replaced as a unit.

Operation

The Accelerator Pedal Position (APP) sensor on the accelerator pedal works according to the Hall principal. The
sensor is integrated into the pedal lever axis. It consists of a shaft with a ring magnet. This rotates in a printed circuit
board with a stator in the fixed Hall elements. This produces a change in the voltage. The APP sensor is supplied
with 5 V from the Engine Control Module (ECM). The information regarding accelerator position is supplied to the
ECM by means of two voltages.
