Abstract:
1. A sensor arrangement for measuring the position of an actuator, which is electromotively operated via a drive connection, of an internal combustion engine, the sensor arrangement having at least a first position sensor and a second position sensor each connected to a circuit, the first and second position sensors being arranged in a housing of the actuator and detecting the position at the drive connection, the circuit containing an operating voltage source and receiving signals from the first and second position sensors, the connection between the circuit and each of the first and second position sensors taking place via at least one line, the lines carrying operating voltage for the first and second position sensors and signals, a first current measuring device and a second current measuring device, each being connected in series with the operating voltage source in the circuit, and current changes being transmitted over the lines via the signals from the first and second position sensors depending on the position of the actuator.
