Abstract
A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft includes determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft, and calculating a crankshaft to camshaft rotational position value indicative of the rotational position of the crankshaft with respect to the rotational position of the camshaft. The crankshaft to camshaft rotational position value is compensated based on the stretch value to provide a compensated crankshaft to camshaft rotational position value and whether the rotational position of the crankshaft correlates to the rotational position of the camshaft is determined based on the compensated crankshaft to camshaft rotational position value.
