Your vehicles Camshaft Position Sensor is a key component to your engine's timing and firing system. The Camshaft Position Sensor in most vehicles sends a signal to the Electronic Control Module (ECM) letting the computer know the position of the engine for timing and fuel injection pulses to the engine.

A bad or malfunctioning cam 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.
