Abstract
A method for determining the angular position of an engine by a crankshaft sensor and a camshaft sensor. The method includes production by the crankshaft sensor of a revolution event, determination of the angular position of the camshaft by identifying the start-of-tooth and end-of-tooth events following the revolution event, in rapid mode, over at most one revolution of the crankshaft, if a no tooth event occurs after the revolution event and if the determination of the angular position of the camshaft fails, the method continues with a step of determining the angular position of the camshaft by identification, in slow mode, over at least two crankshaft revolutions.
