Electronic Throttle Control Module: Testing and Inspection
With Manufacturer's Scan Tool
Throttle Valve Control Module -J338-, Testing
The housing for the throttle valve control module
contains the following components:
-
Throttle drive (power accelerator actuation) -G186-.
(This is an electric motor that is operated by the engine control module. The motor has to overcome spring pressure in order to open the throttle
valve.)
-
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 potentiometers with variable resistance. They inform the engine control module of the position of the throttle valve and are
completely independent of each other.
-
It is not possible to adjust the potentiometers mechanically. Adjustments can be made using vehicle diagnostic, testing and information system
VAS 5051, diagnosis function "04 -Basic settings".
