Throttle Valve Control Module -J338-, CHECKING: Function

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. 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. If one or both sensors fails, a DTC is set into memory and the EPC light is switched ON and the engine only runs at increased idle speed, and no longer responds to the accelerator pedal.

Special tools and workshop equipment required
