2004 Nissan Tiida Camshaft Sensor — What It Does and How to Look After It

Yes, the 2004 Nissan Tiida (C11) is fitted with a camshaft position sensor. This is supported by the Nissan Tiida C11 factory service manual (Engine Control/EC section) where the “Camshaft Position (Phase) Sensor” is specified for HR- and MR-series engines, and by the Nissan FAST parts catalogue that lists a CMP sensor for C11 variants (common Nissan p/n families include 23731-EN20A, application-dependent). Independent catalogues from major sensor manufacturers also list a cam sensor for 2004-on Tiida/Versa models. So it’s definitely relevant to this vehicle.

On a 2004 Tiida, the camshaft sensor keeps the ECU in the loop about cam position so it can fire injectors sequentially, manage ignition timing, and control variable valve timing where fitted. Without a clean signal, the car may crank for ages, stumble off the line, or throw a check engine light with codes like P0340/P0345. It’s a small, solid-state unit mounted at the cylinder head, usually at the front top area under the bonnet, reading a trigger on the cam.

There’s no fixed replacement interval — these sensors are “fit and forget” until symptoms show up. Still, they benefit from a bit of attention during regular servicing: keep engine oil fresh (grubby oil and varnish don’t help precision sensing), check the connector for brittle insulation, and make sure there’s no oil weeping into the plug.

If replacement’s on the cards, it’s a straightforward driveway job for many owners. Basic approach:

• Disconnect the battery and remove the engine cover if fitted.
• Unplug the sensor connector and pull the single retaining bolt.
• Twist the sensor gently to free the O-ring and withdraw it.
• Lightly oil the new O-ring, seat the new sensor, refit the bolt, and reconnect.

Always use quality parts that match your engine code, and tighten the retaining bolt to the service-manual spec. After fitting, clear any stored fault codes and confirm the idle is stable and starts are crisp. If issues linger, check the crank sensor and wiring as they work hand-in-hand.

Common signs the Tiida’s cam sensor is on the way out include:

• Hard starting or long crank when warm
• Rough idle, misfire, or hesitation
• Poor fuel economy and limp-home behaviour
• Check engine light with cam sensor correlation codes

Look after it with clean oil and sound wiring, and the cam sensor will quietly do its job for years and heaps of kilometres.

FAQs

Where is the camshaft sensor on a 2004 Nissan Tiida?
The camshaft sensor is mounted on the cylinder head, typically at the front top of the engine near the cam gear area. Under the bonnet, look for a small sensor with a two- or three-pin plug and a single retaining bolt. Access may require removing the plastic engine cover.

What symptoms point to a failing camshaft sensor on a Tiida?
Expect long cranking, rough idle, random stalling, lack of power, and the check engine light. Fault codes like P0340 or P0345 often appear. Because the ECU relies on both cam and crank signals, similar symptoms can come from crank sensor or wiring faults, so a proper scan and inspection helps.

Is it safe to drive with a dodgy camshaft sensor?
The car may still run, but performance and reliability take a hit. It could switch to a fallback strategy, use more fuel, and stall at awkward times. Best to diagnose and sort it promptly to avoid being stranded and to protect the catalytic converter from misfire damage.
