Abstract
A method for calibrating a crankshaft sensor, of the type including a crankshaft wheel and a sensitive element facing the latter, during replacement of the crankshaft sensor, includes the following steps: saving an old angular position of a camshaft sensor wheel relative to the crankshaft wheel, which is achieved using the old crankshaft sensor, replacing the old crankshaft sensor with a new crankshaft sensor, determining a new angular position of the same camshaft sensor wheel relative to the crankshaft wheel, which is achieved using the new crankshaft sensor, correcting the measurement of the crankshaft sensor by applying an offset equal to the difference between the new angular position and the old angular position.
