2010 Nissan Dualis camshaft sensor — what it does and how to look after it
Technical confirmation: Nissan’s J10 (Qashqai/Dualis) factory service manual, Engine Control (EC) section for the HR16DE and MR20DE petrol engines, specifies a Camshaft Position Sensor (PHASE) mounted to the timing chain case, and the M9R diesel EC section shows a cam sensor as well. Nissan’s FAST electronic parts catalogue for 2010 Dualis also lists a camshaft position sensor for these engines, with diagnostics covering DTCs such as P0340/P0345. That means a camshaft sensor is absolutely fitted and relevant on the 2010 Nissan Dualis.
On a 2010 Dualis, the camshaft sensor tells the ECM exactly where the cam is, so it can sync injection and spark with the crank signal, run CVTC/variable valve timing properly, and get the thing firing up smartly from cold. When it’s healthy, the engine starts cleanly, idles smoothly and pulls well without wasting fuel.
There’s no set service interval for the sensor itself, as it’s a solid-state part. What does make a difference is keeping the wiring and connector under the bonnet tidy. During routine servicing (every 10,000–15,000 km), it’s worth a quick look for oil ingress at the plug, brittle conduit, or rubbed-through loom sections around the timing cover and head. Any contamination on the O-ring seat can be cleaned with sensor-safe electronics cleaner.
Typical signs a Dualis cam sensor is on the fritz include:
- Hard starting or long crank, rough idle, or random stalling
- Flat spots, limp mode, or poor fuel economy
- Check Engine Light with codes like P0340/P0345
Replacement is straightforward on both petrol and diesel variants:
- Disconnect the negative battery terminal.
- Locate the sensor on the timing chain case (petrol) or near the cam end on the head (diesel).
- Unplug the connector, remove the retaining bolt, and ease the sensor out.
- Fit a new O-ring, lightly oil it, seat the new sensor, and tighten the bolt to about 8–10 N·m (check the model-specific spec in the manual).
- Reconnect, clear any codes, and road test. A brief idle relearn may be required.
Quality matters here: choose a genuine Nissan unit or a reputable aftermarket equivalent that matches the engine code (HR16DE, MR20DE, or M9R). If the sensor fails again quickly, look for underlying causes such as oil leaks into the connector or damaged wiring. With a good sensor and clean connections, the Dualis will behave just as it should.
Popular questions
Where is the camshaft sensor on a 2010 Nissan Dualis?
The petrol HR16DE/MR20DE typically places the sensor on the timing chain cover near the top/front of the engine. The M9R diesel positions it at the cylinder head end. Access is under the bonnet with basic hand tools, on some trims you might need to move an intake duct for room.
Can a bad camshaft sensor cause a no-start?
Yes. If the ECM can’t sync cam and crank signals, it may crank for ages, start and stall, or not start at all. You’ll often see a Check Engine Light and fault codes like P0340/P0345. Always check the connector and loom before condemning the sensor.
Do petrol and diesel Dualis models use the same cam sensor?
No. While they do the same job, the part numbers and mounting differ between HR16DE/MR20DE petrol and the M9R diesel. Match parts to the engine code and VIN to avoid fitment dramas.
