Pedal value sensor design - GF30.20-P-4011-02C

Fig 1: Identifying Accelerator Pedal Module With Kickdown Switch (Up To 7/02) Components

Illustration shows accelerator pedal module with kickdown switch (S16/6).

Was only installed until about 7/02. One then used the accelerator pedal module with kick-down simulator (a).

Replace accelerator pedal module always complete!

Fig 3: Identifying Internal Circuitry Of Pedal Value Sensor (Hall Principle)

The sensor on the accelerator pedal which works according to the Hall principle is integrated into the pedal lever axis. It consists of a shaft with ring magnet. This rotates in a printed circuit board with stator in the fixed Hall elements. This produces a change in the voltage.

The accelerator pedal sensor is supplied by the engine control unit with 5 V. The information regarding the accelerator pedal position is passed on to the engine control unit by means of two voltages (pin 4: approx. 0 to 2.25 V and pin 5: approx. 0 to 4.5V).

The kick-down switch (S16/6) was no longer used from 7/02. Full load recognition takes place now over the signal from the accelerator pedal sensor. The pressure point on the accelerator pedal is simulated before achieving the full load position.
