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-
Notes:
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
