Part Number: 23731-4W000
Supersession(s): 237314W000

Camshaft Position Sensor.
A electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft while this information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

  • Part of your vehicle's fuel injection and ignition systems
  • Monitors the engine's many moving parts
  • May need to be replaced if Check Engine Light is on

The position sensor enables operations in your car’s ignition and fuel injection systems. This sensor sends information to your car’s engine control unit (ECU). Then, the ECU leverages this data to direct movements of the corresponding engine components.

If the crankshaft malfunctions, your Nissan engine may malfunction. A few side effects of a worn Engine Crankshaft Position Sensor include odd sounds, misfires, dash lights, stalling, and inconsistent acceleration.

Unlike motor oil, crankshaft sensors don’t need to be replaced regularly. They only need to be serviced according to your Nissan’s manual and replaced as-needed, if issues arise. Typically, an Engine Crankshaft Position Sensor fails due to damage resulting from overheating, failing circuitry, or issues in other engine components, like the timing belt.

Are you noticing knocking sounds, engine misfires, or inconsistent acceleration in your Nissan? In that case, a replacement Engine Crankshaft Position Sensor may be needed. Stop by your nearest Nissan service center for a convenient inspection and diagnostics. If a replacement Engine Crankshaft Position Sensor is needed, ensure you replace the sensor with an original Nissan-made component. Remember that the ECU depends on the crankshaft sensor to ensure your Nissan’s engine top-notch performance and fuel efficiency.
