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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
