Accelerator Pedal Sensor, Basic Function - GF30.20-P-2000A
Model all (4xWD, CAR)
Example of accelerator pedal sensor
Overview
This document contains information on:
- General
- Function
- Limp-home mode
General
The accelerator pedal sensor converts the mechanical actuation of the accelerator pedal into a voltage signal that corresponds to the accelerator pedal position.
Function
The accelerator pedal sensor is integrated in the accelerator pedal pivot. The accelerator pedal sensor consists of a shaft with ring magnet. The ring magnet rotates in a printed circuit board with stator in two fixed Hall elements. This produces a change in the voltage.
Limp-home mode
If the signal voltage of a Hall element fails, the signal voltage of the second Hall element is used and the engine enters limp-home mode.
