Parts for your 2009 Nissan Navara-Camshaft sensor

2009 Nissan Navara camshaft sensor

Yes, the 2009 Nissan Navara uses a camshaft position sensor. This is documented in the Nissan Navara D40 Electronic Service Manual (EC section, 2009), which details the Camshaft Position (PHASE) sensor and related diagnostics, and in the Nissan FAST parts catalogue for the 2009 VIN range. The manual’s DTC listings (e.g., P0340/P0345) also specifically cover camshaft sensor circuits on both the YD25DDTi diesel and the VQ40DE V6 petrol engines.

What does it do? The camshaft sensor tells the engine control module exactly where the cam is in its rotation. Paired with the crank sensor, it lets the ECU time injection and spark (on V6 petrol) spot-on, handle sequential fuel delivery, and manage variable valve timing where fitted. In short, it’s how the Navara keeps cold starts clean, idle steady, and power delivery crisp without chewing through fuel.

When a cam sensor starts misbehaving, the ute can be a pig to start, stumble at idle, go into limp mode, or feel flat through the revs. The check engine light often logs codes like P0340, P0341 or P0345. On the VQ40DE there are two sensors (one per bank), so a code may point to a specific side, on the YD25 there’s a single unit.

Replacement isn’t a massive job, but it pays to be methodical. Disconnect the battery, locate the sensor on the cylinder head (YD25) or at the front of each bank (VQ40DE), unplug the connector, and remove the retaining bolt. Inspect the O-ring and replace it if it’s hardened. Seat the new sensor cleanly, tighten the bolt to the spec in the Nissan ESM, and refit the plug. Clear codes and confirm live data with a scan tool.

They’re not a scheduled service item, but a quick visual during routine servicing is smart: make sure the connector’s clean and locked, the harness isn’t rubbing through, and there’s no oil wicking into the plug. If intermittent faults persist after sensor replacement, check the loom earthing and, on YD25s, consider timing-chain wear or chain-guide issues, as correlation faults can be a symptom of chain stretch rather than a dodgy sensor.

• Use quality OE-equivalent (Hitachi/Nissan) sensors for best reliability.
• If water crossings are your thing, keep an eye on connectors and seals.
• After any timing work, always verify cam/crank correlation with a scan tool.

Popular questions

Where is the camshaft sensor on a 2009 Navara?
On YD25DDTi diesels it’s mounted on the cylinder head, accessed near the timing chain end. On VQ40DE V6 petrol models there’s one sensor on each bank, generally at the front of the heads. Access varies a bit by build and intake layout, but it’s a straightforward reach with basic hand tools.

Can a failing camshaft sensor cause hard starting?
Absolutely. If the ECU can’t trust the cam signal, it may default to batch injection or crank-only strategies, which can mean long cranks, rough idle, and poor throttle response. It’s common to see P0340/P0345 along with these symptoms. Always rule out wiring damage and, on YD25s, timing-chain concerns if issues persist.

Do camshaft sensors need regular servicing?
They’re generally fit-and-forget. There’s no set replacement interval, but checking the connector, wiring and seal during normal servicing helps prevent intermittent faults. Replace the O-ring if it’s weeping, and keep connectors clean and dry, especially if the vehicle sees off-road or marine exposure.
