Throttle Valve Control Module, 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)

• 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 (VAS5051).
