Audi Q7 (4M) 2016-2025 Workshop Manual / Engine / Generic Scan Tool / Diagnosis and Testing / Accelerator Pedal Module - GX2-, Checking

General Description

The Accelerator Pedal Position Sensor -G79- and Accelerator Pedal Position Sensor 2 -G185- are combined in one component and integrated into the Accelerator Pedal Module - GX2-. They are used to detect the position of the accelerator pedal throughout the entire adjustment range. The Engine Control Module - J623- detects the driver's request from these signals and uses them to calculate the injection quantity and EPC throttle valve operation.

The Accelerator Pedal Module - GX2- contains the following components:

  • Accelerator Pedal Position Sensor -G79-
  • Accelerator Pedal Position Sensor 2 -G185-

The Accelerator Pedal Module - GX2- components cannot be serviced separately, and they must be serviced as a unit.
