Patent ID: 7235976

Claim:
A sensor for measuring a position of an actuating element, which is operated electromotively via a drive connection, of an internal combustion engine, comprising: at least one position sensor arranged in a housing of the actuating element wherein the position sensor is configured to detect the position at the drive connection; a circuitry connected to the at least one position sensor, and configured to receive signals from the at least one position sensor; a voltage- and signal-carrying line connecting the circuitry and the at least one position sensor; at least one current measuring device connected in the circuitry to the voltage- and signal-carrying line; and an operating voltage source arranged in a circuit formed by the voltage- and signal-carrying line, the at least one position sensor and the at least one current measuring device, wherein a change in current is transmitted via the voltage- and signal-carrying line via the signals from the at least one position sensor as a function of the position of the actuating element, and wherein the change in current is binary having one current level and another current level, the one current level corresponding to the current flowing through a voltage stabilization circuit in the at least one position sensor and through the operating voltage source, and the other current level corresponding to the current increase by a load connectable in the position sensor as a function of the signals.
