Abstract:
1. A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft, comprising: determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft; 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; compensating said crankshaft to camshaft rotational position value based on said stretch value to provide a compensated crankshaft to camshaft rotational position value; and determining whether the rotational position of the crankshaft correlates to the rotational position of the camshaft based on said compensated crankshaft to camshaft rotational position value.
