The opening angle of the throttle valve will only be determined by the accelerator pedal specification when no
limiting functions are active.
The accelerator pedal position is detected by the set value potentiometer (B37r1) or Hall sensor in the pedal
value sensor (B37) and information is released to the ME control unit (N3/10). In this way, the ME-SFI control
unit determines the position of the throttle valve and actuates the throttle valve motor (M16/1 m1).
The actual value potentiometer in the actuator (M16/1r1) signals the throttle valve position back to the ME-SFI
control unit.
The second potentiometer in the actuator (M16/1 r2) and the second signal from the pedal value sensor
(potentiometer or Hall sensor) supplies a reference value for the plausibility check. In addition, the system
switches over to the second potentiometer or the Hall sensor if the first potentiometer or Hall sensor fails
(emergency mode).
Adaptive accelerator pedal (model 203, 209, 211, 215, 220, 230):
The engine control unit recognizes how the accelerator pedal is being actuated and switches between
characteristic curves. Eighty percent of the engine load is released for a pedal travel of about 50 % for a sporty
driver and about 40 % for a quiet driver. There is no further difference felt above a pedal travel of about 90 %.

If, for example, the characteristic curve for a quiet driver is active after a long drive on the motorway then the
accelerator pedal must be pressed down unusually hard to obtain a higher acceleration level.
Kickdown switch (S16/6)
The kickdown switch was no longer used from 9/01. Recognition of full load is now achieved over the signal
from the pedal value sensor. The pressure point on the accelerator pedal before achieving the full load position
remains.

Fig. 4: Identifying Internal Circuitry Of Pedal Value Sensor
The pedal value sensor based on the Hall principle consists of two Hall elements, 2 magnets, electronics and a
restoring spring. The magnets are moved by means of the linkage or cable attached to the pedal value sensor
and thus alter the direction of the magnetic field relative to the fixed Hall elements. This produces a change in
the voltage.
The pedal value sensor is supplied with 5V only at pin 1. Pin 2 is not connected internally. The information
regarding the accelerator pedal position is passed to the engine control module by means of two voltages (pin 4:
approx. 0 to 2.25V and pin 5: approx. 0 to 4.5V). The pedal value sensor with potentiometer can be replaced
with the pedal value sensor based on the Hall principle (but not vice versa).

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.
