Throttle Valve Control Module -J338-, Checking

Throttle Valve Control Module -J338-, Checking

The following components are located in the housing of the throttle valve control module.
Throttle drive (power accelerator actuation) -G186- (This is an electric motor which is activated by the engine control module. This electric motor opens the throttle valve against the force of a spring).

Angle sensor -1- for throttle drive (power accelerator actuation) -G187-Angle sensor -2- for throttle drive (power accelerator actuation) -G188-.

NOTE:
- Housing for throttle valve control module must not be opened.
- The angle sensors are in the form of potentiometers (variable resistances). They provide the position of the throttle valve to the engine control module completely independently of one another.
- The potentiometers cannot be adjusted mechanically. The settings are made as part of basic setting (function 04) using the vehicle diagnosis, measurement and information system VAS 5051.
