Abstract
A camshaft revolution sensing assembly for identifying a revolution of a camshaft, having a plurality of teeth, of an internal combustion engine of an automotive vehicle includes a camshaft sensor for sensing revolutions of a camshaft by sensing each of the teeth as they rotate therepast and producing a camshaft sensor output, a subtracting device operatively connected to the camshaft sensor, the subtracting device subtracting each time the camshaft sensor senses one of the teeth rotating therepast, and a signal generator operatively connected to the subtracting device wherein the signal generator generates a signal indicating the subtracting device has subtracted to a predetermined value.
