→ Fig.16    Throttle valve potentiometer -G69- or throttle position sender -G79-

Locations:

The potentiometer is part of the throttle valve control part -J338- (arrow). It is located on the throttle valve housing (engine).

The throttle position sender -G79- is part of the electronic power control (EPC) and can be found on the foot pedal.

For self-diagnosis:

The signal from the throttle valve potentiometer indicates the position of the accelerator.

The signal from the throttle position sender gives the same information.

Both signals (messages) are sent to the engine control unit.

The engine control unit relays the signal to the gearbox control unit.

On vehicles with data bus, the signal comes from the bus. On these vehicles, the data bus interface is checked in addition.

The self-diagnosis of the automatic gearbox only checks the signal, not the potentiometer! Additionally the wire for the signal is also checked on vehicles without data bus.

The signal can only be read-out in measured value block.

=> Read measured value block ; Display group number 001

The self-diagnosis of the engine control unit should therefore always be performed when self-diagnosis indicates that this signal is faulty.

Checking and adjusting or removing and installing throttle valve potentiometer
