You will find detailed information on the design and function of the contact-free senders in
the self-study programmes 316 “The 2.0l TDI Engine” or 321 “The Golf 2004 Running Gear”.
Senders for accelerator pedal position G79
and G185
The senders for the accelerator position work
according to the induction principle.
When the accelerator pedal is pressed, the
angle movement is converted into straight-line
movement to move a small metal plate back and
forth.
Evaluation electronics evaluate this movement
and send a corresponding signal to the engine
control unit depending on the accelerator pedal
position.
The engine control unit then calculates the
injection amount from this data.
