Camshaft Position Sensors

Difficulty starting your engine, a lit Check Engine light, poor drivability, and bad fuel economy are all common symptoms of a failing camshaft position sensor (CPS), which is designed to monitor and transmit data on camshaft position and speed. This sensor plays a crucial role in determining both ignition timing and the amount of fuel that enters the combustion chamber. As your camshaft sensor begins to fail—often signified by trouble codes P0340 or P0345—the data it transmits to the ECM weakens, and eventually the vehicle will shut off or fail to start. Don’t risk getting stranded! Summit Racing offers replacement camshaft position sensors from the aftermarket’s most trusted brands, available for a wide range of vehicle makes and models. Each is offered to meet or exceed OEM standards for reliable, maintenance-free operation.
