  FAQ

  What does a crankshaft position sensor do?

  A crankshaft position sensor monitors crankshaft speed and position and sends this information to the engine control module for ignition and fuel injection timing.

  What are common symptoms of a failing crankshaft position sensor?

  Common symptoms include hard starting, stalling, rough idle, misfires, poor performance, and check engine light illumination.

  Can a bad crankshaft position sensor cause a no-start condition?

  Yes. If the ECM cannot determine crankshaft position, the engine may fail to start.

  Can a faulty crankshaft position sensor cause stalling while driving?

  Yes. Loss of crankshaft signal can interrupt ignition and fuel delivery, causing the engine to stall.

  What trouble codes can a bad crankshaft position sensor cause?

  Common codes may include P0335, P0336, P0337, P0338, and P0339 depending on the failure mode and vehicle application.

  Is this the same as a camshaft position sensor?

  No. The crankshaft position sensor monitors crankshaft rotation, while the camshaft position sensor monitors camshaft timing.

  Is this a genuine Nissan part?

  Yes. The 23731-EA20D is a genuine Nissan OEM crankshaft position sensor.
