Walker Products 235-2254 Engine Camshaft Position Sensor

Cam and Crank Position Sensors work together with the vehicle’s ECU to ensure that both ignition timing and fuel supply are correct for peak fuel economy, performance, and emissions. After millions of Cam and Crank rotations, the internal magnets of the sensor weaken causing poor signal transmission. Poor signal can cause improper timing between the Cam and Crank Sensor causing a check engine light and/or vehicle not starting.
