Accelerator pedal sensor component description - GF30.20-P-2010KE

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2007 Mercedes-Benz C350, 2007 Mercedes-Benz C280, 2007 Mercedes-Benz C230, 2006 Mercedes-Benz C55, and 2006 Mercedes-Benz C350. However, it is still accessible from the selected car via links, so may be relevant.

ENGINE 271.921 /940 /941 /944 /946 /948 /955 /956

Arrangement illustrated on model 171

The accelerator pedal sensor is located at the top of the accelerator pedal module.

Task

The accelerator pedal sensor converts the mechanical operation input by the accelerator pedal into an electrical voltage corresponding to the accelerator pedal position.

The kickdown simulator is not an electrical component. It is designed to enable the driver to sense with his foot the point at which the accelerator pedal is fully depressed (full load position).

On models 203, 209 and 211, up to model year 2002, the kick-down switch (S16/6) replaces the kick-down simulator.

The accelerator pedal sensor can be replaced only with the complete accelerator pedal module!

Function

The accelerator pedal sensor consists of a shaft with a ring magnet. This rotates in a printed circuit board with stator in the two fixed Hall elements. This produces a change in the voltage.

Information on the accelerator pedal position is transmitted in the form of two signal voltages (0.20 to 2.25 V and 0.40 to 4.50 V) to the ME control unit (N3/10).
