  Experiencing hard starts or misfires? Restore accurate engine timing and performance with the OEM Nissan Engine Camshaft Position Sensor (Part #23731-4M50D), designed for precise signal feedback to your vehicle’s ECM.

  Engine Camshaft Position Sensor (23731-4M50D) – OEM Replacement Part for Nissan

  This genuine Nissan camshaft position sensor monitors the position and speed of the camshaft to help the ECM control ignition timing and fuel injection. When functioning correctly, it ensures smooth starting, consistent idle, and proper power delivery.
  Unlike the crankshaft position sensor, which tracks crank rotation, the camshaft sensor synchronizes the valve timing — both sensors must work together for accurate engine operation.

  Specifications

  • Part Type: Engine Camshaft Position Sensor

  • Function: Sends camshaft position data to the ECM for ignition and fuel timing

  • Construction: OEM-grade sensor with magnetic pickup and heat-resistant housing

  • Position: Engine cylinder head / camshaft area (varies by engine)

  • Includes: One (1) camshaft position sensor

  Compatible Nissan Models

  • 2003–2018 Nissan Armada (TA60US)

  • 2011–2021 Nissan NV (F80US)

  • 2012–2021 Nissan NV3500 (WF80US)

  Key Features

  • Genuine Nissan OEM part ensures accurate signal calibration with the ECM

  • Restores proper ignition timing and fuel efficiency

  • Prevents stalling, misfires, and extended crank times

  • Precision-machined magnetic core for consistent readings

  • Direct-fit replacement — no wiring or bracket modifications required

  Important Note

  Many vehicles use both camshaft and crankshaft position sensors.
  If you are diagnosing a no-start condition or recurring fault codes (such as P0340, P0345, or P0349), both sensors should be inspected together.

  Always use OEM sensors — aftermarket versions can deliver incorrect resistance or signal range, causing false codes or poor drivability.

  Failing to Replace a Faulty Camshaft Sensor Can Lead To:

  • Hard Starting or No Start: ECM cannot detect proper cam position

  • Rough Idle or Hesitation: Incorrect ignition sequence

  • Reduced Power or Stalling: Loss of synchronization between cam and crank sensors

  • Check Engine Light: Codes such as P0340 or P0345

  • Decreased Fuel Efficiency: Inaccurate valve timing control

  Related Components to Inspect or Replace

  • Crankshaft Position Sensor: Works with the cam sensor to synchronize timing

  • Timing Chain & Guides: Excess wear can cause sensor misreads

  • Camshaft Actuator Solenoid: Check for sludge or electrical faults

  • ECM Connector Pins: Inspect for corrosion or bent terminals

  Order with Confidence

  Order the OEM Nissan Engine Camshaft Position Sensor (23731-4M50D) to restore precise ignition and valve timing. Genuine Nissan sensors ensure compatibility with factory ECM calibration for smooth, reliable engine operation.

  Engine Timing & Sensor FAQ

  Q: Is this the same as the crankshaft sensor?
  A: No — the camshaft sensor monitors valve timing, while the crankshaft sensor monitors engine speed and piston position.

  Q: Can I replace only one sensor?
  A: Yes, but replacing both at the same time is recommended if they are the same age.

  Q: Do I need to clear the code after replacement?
  A: Yes, use a scan tool to clear stored fault codes and allow the ECM to relearn signal timing.

  Q: Will this improve fuel economy?
  A: Yes — a faulty sensor can cause inefficient combustion, leading to lower mileage.
