Fig. 7: 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.
