Abstract
An apparatus for providing an error signal for a control unit, the error signal indicating a malfunction of a sensor unit. The apparatus includes an input module configured to receive a sensor signal from the sensor unit, the sensor signal being a periodic signal between an upper level and a lower level of a physical quantity. Further, the apparatus includes a determination module configured to determine the malfunction of the sensor unit and an output module configured to provide the error signal indicating the malfunction for the control unit. The error signal comprises a predetermined level of the physical quantity which differs from the upper level and from the lower level.
