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.
