Beschreibung
Zusammenfassung:	Disclosed is a camshaft or crankshaft sensor including a toothed target, a measuring cell adapted to supply a raw signal and a processor module having two modes of operation: 1) a measurement mode in which the processor module is adapted to supply an output port of the sensor a measurement signal representing the times of passage of the teeth of the target at the level of the measuring cell; and 2) a diagnostic mode in which the processor module is adapted to supply at the output port of the sensor a diagnostic signal different from the measurement signal and representing the amplitude of the raw signal. Also disclosed is a method and a module for diagnosing such a sensor.
