Throttle Valve Control Module -J338-, Checking



Throttle Valve Control Module -J338-, Checking

The following components are located in the housing for the throttle valve control module:
- Throttle drive (power accelerator actuation) -G186-. (This is an electric motor that is activated by the ECM. This electric motor opens the throttle valve against spring pressure.)
- Angle sensor -1- for throttle drive (power accelerator actuation) -G187-- Angle sensor -2- for throttle drive (power accelerator actuation) -G188-

NOTE:
- The housing for the throttle valve control module must not be opened.
- The angle sensors are designed as potentiometers (variable resistances). They communicate the position of the throttle valve to the Engine Control Module (ECM) fully independent of each other.
- The potentiometers cannot be mechanically adjusted. Adjustments are performed in diagnostic function "04 - basic setting" using the VAS5051 tester.
