Abstract
The invention relates to a crankshaft, transmission or camshaft sensor () for a motor vehicle, intended for being connected to an engine control unit () by a cable (). The sensor comprises a processing module () and a voltage-modifying circuit () configured to generate an output signal via an output port () of the sensor () allowing a diagnosis module () of the engine control unit () to detect and identify faults of the sensor () or the cable (). In particular, the processing module () is configured to provide on its output port (), when the toothed target () is immobile, a predetermined pattern representing the fact that the toothed target () is immobile, this predetermined pattern corresponding to a status change of the output port () of the processing module () with a predetermined time and repeated periodically. The invention likewise relates to a diagnosis system () comprising such a sensor (), a cable () and an engine control unit (). The invention also relates to a diagnosis method () implemented by said diagnosis system ().
