2008 Nissan Navara Camshaft Sensor — What It Does and How To Look After It

Yes, the 2008 Nissan Navara uses a camshaft position sensor. Nissan’s D40 factory service information for both the YD25DDTi 2.5‑litre turbo‑diesel and the VQ40DE 4.0‑litre V6 petrol identifies a “Camshaft Position Sensor (PHASE)” as part of the engine control system. Technical references such as Nissan EC (Engine Control) manuals and mainstream parts catalogues for the 2008 Navara list this sensor as standard equipment across the range.

On this model, the camshaft sensor works with the crankshaft sensor to pinpoint cam angle and cylinder phase. The ECU then uses that signal to time fuel injection and spark (petrol), manage variable valve timing on V6 models, and ensure accurate injection phasing on the YD25 diesel. When the signal goes missing or erratic, the Navara can be slow to start, run rough, drop into limp mode, or log fault codes like P0340/P0341 (and P0345/P0349 on V6 bank 2).

It’s not a routine replacement item, but it’s smart to include a quick check in regular servicing. Under the bonnet, the sensor sits on the cylinder head near the timing end (V6 models have one per bank). Oil contamination, heat, vibration, or a damaged harness plug are the usual culprits when issues pop up. A basic service check can include:

• Inspecting the connector and loom for broken locks, corrosion, or chafed wiring.
• Looking for oil wicking through the plug or a hardened O‑ring at the sensor body.
• Scanning for stored codes even if the MIL isn’t on, and checking cam/crank sync data.

If replacement is needed, it’s a straightforward job for most engines: remove the engine cover, unplug the sensor, undo the single retaining bolt, swap the sensor (fit a fresh O‑ring lightly oiled), then refit and clear codes. Typical retaining bolt torque is about 9–10 N·m, but it’s best to follow the exact spec in the Nissan workshop manual for the specific engine. After replacement, an idle relearn may be required so the ECU settles trims quickly.

Quality matters here. A genuine or reputable OEM‑grade sensor helps avoid intermittent sync faults that cheaper copies can trigger. When symptoms include long cranking, sudden stalling, or repeated cam signal codes, tackling the camshaft sensor and its wiring early can save a lot of mucking about down the track.

• Does a 2008 Nissan Navara have one or two camshaft sensors?
  The YD25 2.5‑litre diesel typically uses one camshaft sensor. The VQ40DE 4.0‑litre V6 petrol uses two — one on each bank (bank 1 and bank 2). Either way, the ECU relies on the cam signal for proper phasing, so a fault will usually set a DTC and affect driveability.
• What fault codes point to a dodgy camshaft sensor on a D40 Navara?
  Common codes include P0340 and P0341 for camshaft position circuit or performance issues. On the V6, P0345 and P0349 can appear for bank 2. These may be sensor faults, wiring/connectors, or less commonly, timing or ECU issues — so a quick visual check and proper diagnosis are worth it.
• Is it safe to keep driving with a failing camshaft sensor?
  It might still run, but it’s risky. The engine can stumble, lose power, or stall, and it may crank longer when hot. Limp mode and poor fuel economy are common. Best bet is to get it scanned and sorted before it leaves someone stranded.
