2017 Nissan Navara camshaft sensor: what it does and how to look after it

Based on technical references, the 2017 Nissan Navara (D23/NP300) is fitted with and relies on a camshaft position sensor, so it’s absolutely relevant to servicing and diagnostics. The Nissan Navara D23 Series Workshop Manual (EC – Engine Control) details the “Camshaft Position Sensor (PHASE)” for the YS23DDT/DDTT 2.3‑litre diesel, and the Nissan Electronic Parts Catalogue (FAST) lists a dedicated sensor assembly (commonly referenced under 23731‑ prefixed part numbers) for this model. Bosch EDC17 engine management used on the YS23 engine family also specifies a camshaft signal for cylinder identification and injection phasing. That all confirms the sensor is present and used.

On a 2017 Navara, the camshaft sensor feeds the ECU precise cam position so it can sync with the crank sensor. That lets the ECU fire pilot, main and post injections to the correct cylinder at the right moment for clean starts, smooth idle and proper torque. It also helps with misfire monitoring and keeps emissions kit like the DPF working as intended. If the cam sensor goes out, the ute may crank longer, run rough, drop power, and throw DTCs such as P0340/P0341. In many cases it’ll still run using crank-only fallbacks, but not happily.

There’s no set replacement interval, but as part of routine servicing it’s smart to inspect the sensor and its connector for oil wicking, water ingress or harness chafe along the rocker cover area. Keep the plug clean and seated, especially after engine-bay washing or off‑road work. If replacement’s needed, it’s a straightforward job: disconnect the battery, unplug the 3‑pin connector, remove the retaining bolt, and ease out the sensor (there’s an O‑ring). Lightly oil the new O‑ring, refit, and tighten the bolt to the workshop‑manual spec. Clear any codes and check cam/crank sync with a scan tool. Quality OEM‑grade parts (e.g., Hitachi/Bosch) are recommended to avoid intermittent faults and starting dramas.

• Typical symptoms: long crank, rough idle, reduced power, MIL on.
• Common DTCs: P0340, P0341, occasionally cam/crank correlation codes.
• Location: usually on or near the rear/top of the cylinder head, reading a cam trigger.
• Service tip: inspect at major services (around 60,000–80,000 km) and after any wiring work.

FAQs

Where is the camshaft sensor on a 2017 Navara?
It’s typically mounted on the cylinder head, reading a target on the camshaft. On the YS23 diesel, look at the upper rear/side of the head near the rocker cover. Access is usually from above, remove engine covers for a clear view of the 3‑pin connector and small retaining bolt.

What are the common signs of a failing camshaft sensor?
Longer cranking when warm or cold, uneven idle, flat spots, and the check engine light are tell‑tales. Fault codes like P0340/P0341 are common. The engine can still run using the crank sensor, but performance and starting suffer. If ignored, it may eventually stall or fall into limp mode.

Does a new camshaft sensor need programming?
Generally, no coding is required. Fit the new sensor, then clear fault codes and verify cam/crank synchronisation with a scan tool. If the ECU had adapted to a weak signal, a quick idle relearn or short drive cycle can help stabilise starts and idle quality.
