Electronic Throttle Control Module: Component Tests and General Diagnostics
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 made in Basic Setting (function 04) using the VAS5051 tester or VAG 1551
Scan Tool.
