The accelerator position sender transmits the
driver inputs to the Motronic.
Subsystems of the Motronic
The accelerator position sender transmits to
the Motronic an analogue signal correspon-
ding to the accelerator pedal position. To
ensure the functional reliability of the electro-
nic throttle control, the accelerator position
sender has two independent potentiometers
G79 and G185.
The characteristics are different (refer to dia-
gram).
The control unit monitors the function and
plausibility of the two senders G79 and G185.
If a sender fails, the other sender acts as a
back-up.

The electronic throttle control function is used
to reduce and increase torque without adver-
sely affecting the exhaust emission values.
