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 activation) - 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 activation) -G187-
-
Angle sensor -2- for throttle drive (power accelerator activation) -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 VAS5051.
