Camshaft position sensor suitable for a wide range of Nissan and Infiniti vehicles. The camshaft position sensor monitors camshaft position and sends this information to the engine ECU, allowing accurate control of ignition timing, fuel injection and engine synchronization.
A faulty camshaft position sensor can cause symptoms including difficult starting, intermittent stalling, poor running, engine misfires, loss of power, engine warning lights or a crank/no-start condition.
This is a direct replacement 3-pin aftermarket sensor supplied with mounting point and seal as pictured.
Note: This is an aftermarket replacement part.
