Parts for your 2008 Nissan Dualis-Crank angle sensor

2008 Nissan Dualis crank-angle sensor: what it does and how to deal with it

Yes, the 2008 Nissan Dualis (J10 – known elsewhere as Qashqai) is fitted with a crank-angle sensor, more commonly called the crankshaft position (CKP) sensor. This is documented in the Nissan Qashqai/Dualis J10 Series Service Manual under the Engine Control (EC) section, which details the “Crankshaft Position Sensor (POS)” and its role in ignition and injection timing. Nissan’s FAST parts catalogue lists the CKP for J10 MR20DE engines (e.g., sensor family 23731-****), and independent references such as Autodata’s Engine Management data for the 2008 Qashqai/Dualis also list a CKP as standard equipment.

On the 2008 Dualis, the crank-angle sensor reads a toothed wheel on the crankshaft and sends a precise speed and position signal to the ECM. That live data lets the engine computer fire the spark and inject fuel at the right moment, coordinate variable valve timing, and stabilise idle. Without a clean CKP signal, the engine can be hard to start, misfire, stall, or not run at all.

While it’s not a scheduled service item, it’s smart to keep an eye on it during regular servicing. Owners and techs should check for oil contamination at the connector, heat-hardened wiring near the bellhousing, and stored fault codes such as P0335/P0336. A quick scan under the bonnet and along the loom for abrasion or loose clips can prevent intermittent faults, especially in Aussie and Kiwi conditions with heat and dust.

Replacement is straightforward with basic tools, and suits driveway DIYers who are comfortable working under the vehicle:

• Disconnect the battery and safely raise the car. The sensor is typically low on the block near the gearbox bellhousing on MR20DE petrol models (diesel locations vary but the function is the same).
• Unplug the connector, remove the retaining bolt, and withdraw the sensor with its O-ring.
• Lightly oil the new O-ring, seat the sensor fully, and tighten the bolt to the specification in the Nissan service manual.
• Reconnect, clear any DTCs, and start the engine. The ECM will sync to the new signal immediately, a long idle relearn is usually unnecessary.

Signs it’s time to act include intermittent stalling when hot, a dead tach during crank, long crank/no start, or a sudden cut-out at traffic lights. Using a quality OEM-equivalent sensor and keeping the loom tidy will help the Dualis run sweet for many more kilometres.

Popular questions about the 2008 Nissan Dualis crank-angle sensor

Where is the crank-angle sensor located on a 2008 Dualis?
On most 2.0L MR20DE petrol models it’s mounted low on the engine block at the transmission bellhousing area, accessible from underneath. On diesel variants the position can differ slightly, but it still reads the crank via a reluctor on the crankshaft.

Will a failing crank-angle sensor cause intermittent stalling or no-start?
Yes. Heat-soak faults often show as a hot stall followed by an extended crank or no-start until it cools. The ECM may log P0335/P0336 and the tacho can drop out while cranking. If wiring and power/earth are healthy, the sensor itself is commonly the culprit.

Do they need a relearn after replacement?
Generally, no specific CKP relearn is required. Clear codes, start the engine, and the ECM will synchronise immediately. If the battery has been off, an idle refinement may occur during a short drive, a manual idle learn is rarely needed unless idle remains unstable.
