Parts for your 2007 Nissan Dualis-Camshaft sensor

2007 Nissan Dualis camshaft sensor — fitted, what it does, and how to look after it

Yes, the 2007 Nissan Dualis (J10 — known elsewhere as Qashqai) uses a camshaft position sensor. This is documented in Nissan’s factory service information for the J10 series: Engine Control (EC) sections for HR16DE, MR20DE, and the diesel variants detail the “Camshaft Position Sensor (PHASE)” input to the ECM for sequential injection and variable valve timing control. Parts catalogues for J10 models also list a dedicated camshaft position sensor assembly for these engines. Recognised references include: Nissan Qashqai/Dualis J10 Service Manual (EC section: Camshaft Position Sensor – PHASE), MR20DE Engine Mechanical and EC diagnostics, and aftermarket catalogues from OEM sensor suppliers that specify a CMP for 2007 J10 engines.

On a 2007 Nissan Dualis, the camshaft sensor is a small but critical bit of kit. It reads the position of the camshaft as the engine spins, letting the ECU fire the injectors and spark at the right time and manage variable valve timing. If it goes out of whack, the Dualis can crank longer before starting, idle rough as guts, hesitate on take-off, or even drop into limp mode. Fuel economy can suffer too, and you’ll often see an engine light with codes like P0340 or P0341.

It’s not a regular service item, but giving it some love during routine servicing pays off. Under the bonnet, the sensor sits on the cylinder head near the timing chain end (location varies slightly by engine). During oil changes, a quick visual once-over for oil seeping into the connector, brittle wiring, or a loose retaining bolt is a smart move. Keep the plug clean and seated firmly — poor connections cause more grief than the sensor itself.

If replacement’s needed, it’s typically a straightforward job: disconnect the battery, let the engine cool, unplug the connector, remove the single retaining bolt, and ease the sensor out. Swap the O‑ring for a new one, lightly oil it, seat the new sensor squarely, and tighten the bolt to the factory spec from the service manual. Clear any fault codes and confirm live data or a clean restart. Using a reputable OE-equivalent sensor (Hitachi/NTK/Bosch spec) helps avoid repeat issues.

Handy signs it’s time to test or replace the cam sensor:

• Hard starting, especially when hot
• Stalling, rough idle, or flat spots
• Check engine light with cam sensor codes (P0340/P0341)
• Poor fuel economy or sluggish performance

A good scan tool can confirm the cam/crank sync. If both the cam and crank sensors are original and high‑kilometre, testing them as a pair is sensible. Always refer to the J10 service manual for procedures and torque values.

Popular questions about 2007 Nissan Dualis camshaft sensors

Where is the camshaft sensor on a 2007 Dualis?
It’s mounted on the cylinder head at the timing chain end. On the MR20DE petrol, you’ll find it near the top front of the engine, secured by a single bolt with an O‑ring seal. Access is usually from above with basic hand tools after removing the engine cover.

Can a bad camshaft sensor damage the engine?
It’s unlikely to cause direct internal damage, but it can lead to hard starting, misfires, and poor running. Left unchecked, that rough running can stress the catalyst and increase fuel use. If the light’s on with cam sensor codes, fix it sooner rather than later.

Do I need to replace both the cam and crank sensors together?
Not strictly, but many techs test both. If one has failed on a high‑kilometre Dualis, the other may not be far behind. Verifying signals with a scan tool or scope helps decide whether to replace one or both.
