Parts for your 2008 Nissan Navara-Crank angle sensor

2008 Nissan Navara Crank Angle Sensor

According to Nissan’s Electronic Service Manual (ESM) for the 2008 Navara range (D22 and D40) and common engine management references (EC section for YD25DDTi, QR25DE and VQ40DE), this model is fitted with a crank angle sensor, also known as the crankshaft position sensor (CKP). Nissan parts catalogues list the CKP for these engines and factory diagnostics reference DTCs such as P0335/P0336 for the sensor circuit, confirming its use on 2008 Navara variants.

The crank angle sensor is the engine’s timing eyes. It reads a toothed wheel on the crankshaft and feeds precise position and speed data to the ECU. That lets the ECU fire injectors and coils at exactly the right moment, manage idle quality, and protect the engine under load. If the signal goes missing or messy, the engine can crank without starting, stumble, misfire, or stall at idle. The check engine light often logs codes like P0335.

While not a scheduled replacement item, it deserves attention during servicing. Smart checks include: inspecting the wiring loom for chafing near the bellhousing, confirming the connector is clean and latched, and looking for oil weeps that could wick into the plug. On magnetic-tipped designs, a build‑up of fine metal fuzz can upset the signal, carefully wiping the tip clean can help if the sensor is removed.

Replacement is direct if a fault is confirmed. Steps typically involve: disconnecting the battery negative, accessing the sensor (on YD25DDTi it’s mounted at the rear of the engine reading the flywheel, on VQ40DE it’s also near the transmission bellhousing, on QR25DE it’s mounted at the block by the crank pulley area), unplugging the connector, removing the retaining bolt, and swapping in an OE‑quality sensor with a new O‑ring if specified. Seat it fully and tighten the bolt to manufacturer spec (about 9–10 N·m per Nissan ESM guidance). Clear codes, then check live data for a stable RPM signal and road‑test to confirm hot and cold starts are crisp.

Common signs that the Navara’s crank angle sensor needs attention:

• Intermittent no‑start when hot, then starts again once cooled
• Rough idle, sudden stalling at traffic lights, or limp behaviour
• Check Engine Light with P0335/P0336 stored

When sourcing a replacement, using genuine or trusted aftermarket parts that meet OEM spec will keep timing accuracy spot‑on and avoid repeat faults.

Popular questions about the 2008 Nissan Navara crank angle sensor

Where is the crank angle sensor on a 2008 Navara?
On YD25DDTi diesels (D22 and D40), it’s typically mounted at the rear of the engine, reading the flywheel through the bellhousing area. On the VQ40DE petrol V6, it’s also positioned near the transmission bellhousing. On QR25DE petrol variants, it’s usually on the block near the crank pulley. Access varies by model and transmission cross‑member.

What symptoms point to a failing crank angle sensor?
Hard starting when hot, random stalling, uneven idle, misfires, and a Check Engine Light are common. Scan tools often show P0335 or P0336. If the tachometer drops to zero during a stall and there’s no RPM shown on live data while cranking, the CKP signal is suspect.

Does it need regular replacement?
It’s not a scheduled item. Many last the life of the vehicle. However, heat and vibration can fatigue them over the years. As part of servicing, a quick loom/connector inspection and fault‑code scan is sensible. If confirmed faulty, replacement is usually a straightforward 0.5–1.0 hour job.
