ABSTRACT:
A sensor measures the position of an actuator of an internal combustion engine, wherein the actuator is electromotively driven by means of a drive connection. The housing of the actuator accommodates at least one position sensor which detects the position at the drive connection. At least one position sensor is connected to a circuit with an operating voltage source and receives signals from at least one position sensor. The circuit and the at least one position sensor are connected via a cable that conducts voltage and signals. The circuit comprises also at least one current measuring device connected in series to the operating voltage source. A current change is transmitted via the cable by means of the signals generated by the at least one position sensor depending on the position of the actuator.
