Crankshaft Position Sensor: Description and Operation
The crankshaft position sensor is a hall effect device that generates one pulse per cylinder combustion stroke from a four tooth reluctor wheel attached to
the engine crankshaft. The pulse is used in order to locate the cylinder reference event (top dead center) for each cylinder. The PCM uses this
information in order to adjust the timing, trigger real time events and is used in the injection pump cam signal diagnostic.
