  Key Features

  • Genuine Nissan OEM sensor ensures precise timing signal and ECM calibration

  • Restores proper ignition and fuel synchronization

  • Prevents stalling, no-start, or misfire issues

  • Factory-sealed housing protects against oil and vibration

  • Direct-fit replacement for quick installation and reliable connection

  Important Installation Note

  On certain Nissan engines, this part may be installed at different locations and serve as either the camshaft or crankshaft position sensor. Always verify installation point and connector shape before replacement.

  If a Check Engine Light (CEL) or timing-related DTC persists after installation (e.g., P0340, P0335, P0345), ensure both sensors (cam and crank) are properly connected and that ECM relearn procedures are completed.

  Failing to Replace a Faulty Sensor Can Lead To:

  • No-Start or Hard Start Condition: ECM cannot determine engine position

  • Misfiring or Stalling: Inaccurate timing signals affect ignition synchronization

  • Poor Fuel Economy: ECM enters fail-safe mode

  • Check Engine Light / DTC Codes: P0340, P0335, or related timing errors

  • Reduced Engine Performance: Loss of timing control or delayed ignition

  Related Components to Inspect or Replace

  • Companion Camshaft or Crankshaft Sensor: Replace as a matched set for accuracy

  • Timing Chain & Tensioners: Check for wear affecting signal consistency

  • Oil Control Solenoid (VTC): Ensure proper oil pressure for timing accuracy

  • ECM Connectors: Clean terminals to prevent intermittent signal faults

  Order with Confidence

  Order the OEM Nissan Camshaft/Crankshaft Position Sensor (23731-JA11B) to restore factory engine timing synchronization and performance. Genuine Nissan sensors are engineered to communicate seamlessly with your vehicle’s ECM for reliable ignition and fuel control.

  Engine Sensor & Timing FAQ

  Q: Is this sensor used for cam or crank position?
  A: It depends on your vehicle and engine type. On some models, this sensor serves as a camshaft sensor; on others, it functions as a crankshaft sensor. Always confirm location before ordering.

  Q: Do I need to replace both sensors?
  A: If one has failed, it’s often recommended to replace both simultaneously to ensure matching signal response.

  Q: Can I install it myself?
  A: Yes, it’s a direct-fit part, but ensure proper orientation and connector engagement.

  Q: Will this clear a P0340 or P0335 code?
  A: Yes, if the fault is due to a failed sensor. Clear codes and perform an ECM relearn if required.
