Abstract
A system and method is provided for determining changes in the angular position of a driven pulley, with respect to a driving pulley, when the driven and driving pulleys are synchronously linked by a flexible drive member such as a toothed belt or a chain. From these determined changes in the angular positions, the system and method can determine the condition of the flexible drive member and can output an appropriate signal when the condition of the flexible drive member has exceed a pre-defined value. Further, the system and method can detect a variety of other undesired conditions in the operation of an engine and/or the relative angular position information can be used to alter operation of the engine to improve the engine's operating efficiency and/or reduce the emissions created during operation of the engine.
