ABSTRACT:
A crankshaft reversal detection system includes a sensor module and a control module that communicates with the sensor module. The sensor module detects position of a belt tensioner that communicates with a crankshaft driven accessory drive belt. The control module determines a rotational direction of the crankshaft pulley based on the position of the belt tensioner.
