This engine crankshaft position sensor is designed to match the fit and function of an original sensor to help ensure the engine control unit receives proper inputs when an original sensor has failed from heat or internal component damage.

An essential component in the diesel electronic control system, this sensor provides the vehicle powertrain control module (PCM) with crankshaft position and engine speed. The PCM uses this to calculate accurate fuel injection timing. Failure of this component can result in a check engine light, engine misfire, no-start condition and poor drivability.
