Parts for your 2010 Nissan Serena-Crank angle sensor

2010 Nissan Serena crank angle sensor (crankshaft position sensor)

Yes, the 2010 Nissan Serena is fitted with a crank angle sensor, commonly referred to by Nissan as the crankshaft position sensor (POS). Technical references that confirm this include the Nissan Serena C26 series Service Manual (EC – Engine Control section) which details the “Crankshaft Position Sensor (POS)” and associated DTCs such as P0335, and the Nissan parts catalogue for Serena C25/C26 models which lists the crankshaft position sensor as a serviceable component (typical Nissan part families include 23731-****A for MR-series engines). These sources make it clear the Serena’s MR20DE/MR20DD engines rely on a dedicated crank angle/position signal for ignition timing and sequential fuel injection.

The crank angle sensor on a 2010 Serena does the critical job of telling the engine control module exactly where the crankshaft is and how fast it’s spinning. That timing info is what keeps spark and fuel events bang on, so the van starts cleanly, idles smoothly and doesn’t drink more fuel than it should. If the signal drops out, the ECM can’t coordinate everything and you’ll cop hard starting, random stalling, misfires, sluggish response or a no-start after a hot soak.

There’s no fixed replacement interval, it’s a condition-based item. During regular servicing, it’s smart to give the wiring and connector a once-over. Look for oil wicking into the plug, broken loom clips, or damage from road debris. On MR-series Serenas the sensor sits down by the bellhousing reading the flywheel teeth, so it lives in a hot, grubby spot. Keeping the connector clean and seated, and ensuring the harness isn’t rubbing through, will save headaches.

If replacement’s on the cards, use an OEM-quality sensor and a fresh O-ring. Typical driveway steps are straightforward: disconnect the battery, remove any intake ducting for access, unplug the connector, crack the single retaining bolt, and twist the old sensor free. Lightly oil the new O-ring, seat the sensor fully, and tighten the bolt to the service-manual spec. After fitting, clear any fault codes and perform an idle/air volume learn if required so the ECM is happy. Avoid blasting the area with a pressure washer and keep metal filings away from the tip—magnetic debris can distort the signal.

• Common signs it’s failing: intermittent no-start (especially hot), rough idle, sudden stall, poor fuel economy, and a check engine light with codes like P0335/P0336.
• Good practice: inspect at major services, fix oil leaks that can contaminate the plug, and don’t ignore early stumbles—catching a weak signal early can prevent a roadside drama.

FAQs

Where is the crank angle sensor on a 2010 Serena?
It’s mounted low on the engine at the transmission bellhousing, aimed at the flywheel/ring gear. Access is from the front underside or after moving the intake ducting under the bonnet, depending on variant.

Can you drive with a failing crank angle sensor?
You might—for a bit. But expect intermittent stalling or a sudden no-start once hot. It’s safer to diagnose and replace promptly to avoid being stranded.

Do I need to program anything after replacement?
There’s no coding for the sensor itself, but clearing DTCs and performing an idle/air volume learn is recommended so the ECM settles into a stable idle.
