Zusammenfassung:	A sensor for a motor vehicle, the vehicle including a combustion engine and an engine control computer. The engine includes at least one drive shaft able to be driven in rotation, the at least one drive shaft having at least one magnetic element, the sensor being disposed facing the at least one magnetic element, the computer being configured to determine the angular position of the at least one drive shaft in relation to a predefined reference angular position on the basis of an output signal supplied by the sensor, the sensor being characterized in that it is able to generate a square wave output signal. Each square wave is characterized by an initial instant and a temporal width, by associating each initial instant with a predefined angular position of the drive shaft.
