Example of accelerator pedal sensor 

Overview 

This document contains information on:

General 

The accelerator pedal sensor (1) converts the mechanical actuation of the accelerator pedal into a voltage signal that corresponds to the accelerator pedal position.

Function 

The accelerator pedal sensor (1) is integrated on the accelerator pedal pivot. The accelerator pedal sensor (1) 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.
