Throttle valve angle
Angle sensor -2- for throttle drive -G188-
Throttle valve angle
Angle sensor -1- for throttle drive -G187-
Note on display group 62:
The angle sensors for the Throttle Valve Control Module and the Throttle Position
(TP) sensor are featured in pairs for reasons of safety. The Motronic Engine Control
Module (ECM) -J220- constantly checks the plausibility of the potentiometers.
The value from Sender -2- for accelerator pedal position -G185- must display approx.
half the value of Throttle Position (TP) sensor 1 -G79- at all times.
The angle sensors for throttle drive are opposed. The values from both angle
sensors must always add up to approx. 100 %.
The specifications do not fully reach the max./min. figures.
