Mercury Crankshaft Sensor

Your vehicles Crankshaft Sensor is a key component to your engine's timing and firing system. The Crank Sensor in most vehicles usually uses a magnet to determine the position of the crankshaft and sends the info to the Electronic Control Module (ECM) letting the computer know the position of the engine.

A bad or malfunctioning crank sensor will often cause a service engine light error code, and or cause a no start condition, or rough running due to inaccurate ignition and fuel timing.
