2016 Nissan Serena Camshaft Sensor — Purpose, Fitment, and Servicing Advice
Based on Nissan factory service information for the C26 and early C27 Serena (EC/Engine Control sections) and Nissan’s electronic parts catalogue, the 2016 Nissan Serena is fitted with a camshaft position sensor (often labelled “PHASE” in service literature). Diagnostic procedures list related DTCs such as P0340/P0345, confirming that the engine management relies on a camshaft sensor for timing and variable valve control on the MR-series 2.0L petrol engines used in this model year.
On the 2016 Serena, the camshaft sensor helps the engine control module know exactly where the cam is in its rotation. That lets the ECU sync fuel injection, ignition timing, and the Serena’s variable valve timing properly. It’s especially important for smooth starts, low idle emissions, and that easy stop–start behaviour on S-Hybrid variants. Without a clean signal, the van can crank longer, stumble, or drop into limp mode with a check engine light.
Typical signs of a crook cam sensor include:
- Hard starting, misfiring at low revs, or stalling at lights
- Sluggish throttle response and poor fuel economy
- Check engine light with codes like P0340/P0345
Location-wise, the sensor sits on the cylinder head near the cam sprocket under the front of the rocker cover, with a single retaining bolt and a two- or three-pin connector. It’s a small job for a competent home mechanic, but it still pays to take care.
- Disconnect the battery negative and let the vehicle sit a few minutes.
- Unplug the sensor connector, check for oil intrusion or damaged pins.
- Remove the retaining bolt (typically a 10 mm head), ease the sensor out, and wipe the bore.
- Lightly oil the new O-ring, seat the new sensor, and tighten the bolt to light factory torque (around 8–10 N·m is common for this style).
- Reconnect, clear fault codes, and road test from cold.
As part of regular servicing, it’s sensible to visually inspect the connector, harness routing, and any oil leaks from the rocker cover that could wick into the plug. There’s no scheduled replacement interval, but high kilometres, heat, and oil contamination can age sensors. Using quality parts that match the Nissan spec and keeping engine earths clean will help the Serena’s ECU maintain crisp timing, smooth idle, and tidy fuel use.
Popular questions
Where is the camshaft sensor on a 2016 Nissan Serena?
The sensor is mounted on the cylinder head at the timing chain end, near the cam sprocket, under the front section of the rocker cover. It’s held by a single small bolt with an easy-to-spot electrical connector. On some variants there may be an intake-side sensor, access is typically from the top once the engine cover is off.
What symptoms point to a failing camshaft sensor on this model?
Owners often report longer cranking, rough idle, misfires at low revs, and poorer fuel economy. The check engine light usually appears, commonly logging P0340 or related cam/crank correlation codes. If the signal drops out intermittently, the Serena might stall when warm or hesitate on take-off.
Does the camshaft sensor need regular servicing?
There’s no fixed change interval, but during routine services it’s smart to check for oil weeping at the rocker cover, cracked wiring insulation, or loose connectors. Keeping the area clean and addressing leaks early helps prevent sensor contamination and premature failure.
