Throttle Valve Control Module -J338-, Checking

The following components are located in the housing of the Throttle Valve Control Module -J338-.
- Throttle drive (power accelerator activation) -G186-. (This is an electric motor which is activated by the Engine Control Module (ECM). This electric motor opens the throttle valve against the force of a spring).
- Angle sensor 1 for throttle drive (power accelerator activation) -G187-.
- Angle sensor 2 for throttle drive (power accelerator activation) -G188-.

NOTE:
- The housing of the Throttle Valve Control Module -J338- 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 (ECM) 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.
