Parts for your 2007 Nissan Serena-Crank angle sensor

2007 Nissan Serena crank-angle-sensor: purpose, fitment and servicing tips

Yes, a crank-angle-sensor is fitted to the 2007 Nissan Serena (C25). Technical references that confirm this include the Nissan Serena C25 Factory Service Manual (Engine Control/EC section), which details the “Crankshaft Position Sensor (POS)” as a primary ECU input for ignition and injection timing, and the Nissan FAST parts catalogue, which lists the crankshaft position sensor under group 23731 for C25 MR20DE models (and equivalent listings for diesel variants). Nissan documentation often uses “crankshaft position sensor” and “crank angle sensor” interchangeably.

On the Serena’s MR20DE petrol engine, the crank-angle-sensor is mounted at the gearbox bellhousing side of the block, reading a toothed wheel on the crank. Its job is to tell the ECU exactly where the crank is and how fast it’s spinning. That info is the heartbeat for spark timing, fuel injection timing, misfire monitoring and starting. If the signal drops out, the Serena can be hard to start, stall, or run roughly. Typical fault codes include P0335/P0336.

There’s no scheduled replacement interval for the crank-angle-sensor, it’s a fit-and-forget item until symptoms or a fault code pop up. During servicing, it’s worth a quick look for oil seepage, heat-hardened wiring, or a loose connector. Keeping the harness clipped correctly and the plug clean and dry goes a long way.

Replacement is straightforward for most DIYers:

• Disconnect the battery and let the vehicle sit a few minutes.
• Access the sensor from underneath near the bellhousing, unplug it, remove the retaining bolt and pull the sensor straight out.
• Lightly oil the new O-ring, seat the sensor fully, and tighten the bolt to the factory torque spec (refer to the C25 FSM).
• Clear codes and, if the battery’s been off, perform the Nissan idle/air volume learn so it idles nicely.

Signs it’s on the way out include longer cranking when hot, random stalling at lights, a dead tach during cranks, or the Serena suddenly going into limp mode. If those show up, scanning for codes before throwing parts at it is smart. Using quality, OEM-equivalent sensors keeps the ECU happy and saves repeat jobs.

Popular questions about the 2007 Nissan Serena crank-angle-sensor

Does a 2007 Nissan Serena have a crank-angle-sensor?
Yes. The C25 Serena uses a crankshaft position (crank-angle) sensor as a core engine management input. Nissan’s C25 service manual and parts listings show it as standard on MR20DE petrol and applicable diesel variants.

What are common symptoms of a failing crank-angle-sensor on a Serena?
Hard starting (especially hot), intermittent stalling, rough running, no-start with spark/fuel cut, and engine light with P0335/P0336 are classic. A quick code scan and live data check will usually point straight to it.

Can the Serena run with a faulty crank-angle-sensor?
If the signal is intermittent, it may start and then stall or misfire. If it fails completely, the engine generally won’t start because the ECU can’t time spark and fuel without that signal.
