402 Throttle Jacking Unit, Position Error - Signal Implausible: Function

The throttle angle demanded by the DME control module is achieved by means of a digital position controller. The rapid and precise setting of the desired throttle position is of major importance for the quality of charging control.

In the event of a position error fault, the throttle angle measured by the potentiometers does not match the calculated throttle angle.
