Throttle valve actuator, function - GF30.22-P-4101-02HA
The actuator motor in the throttle valve actuator adjusts the opening angle of the throttle valve continuously from approx. 0 to 90° according to the presets from the ME control unit (N3/10). Hereby, both the actual value potentiometers indicate the current position of the throttle valve to the ME control unit.
In deenergized status (e.g limp-home), the opening angle of the throttle valve (from 10 to 12°) is determined by the spring capsule.
When the throttle valve actuator is connected to the vehicle for the first time, the ME control unit carries out an adaptation of the actuator (learning the lower and upper mechanical end stop of the throttle valve) on its own.
A throttle flap actuator with a larger cross section will be installed starting 03/2006.
