Duralast Crankshaft Position Sensor SU4182

Camshaft and crankshaft position sensors identify position to the ignition control module module (ICM), engine control module (ECM) or powertrain control module (PCM). When not replaced your vehicle could experience no start, a hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy and more. These sensors are engineered using high quality components and materials to ensure proper function and response. They are tested for proper timing of the camshaft and ignition. They go through an ongoing fit, form and function process and meet or exceed OE specifications.
