Parts for your 2016 Nissan Pulsar-Camshaft sensor

2016 Nissan Pulsar camshaft sensor – what it does and when to replace it

Yes, the 2016 Nissan Pulsar is fitted with a camshaft position sensor. Nissan’s Electronic Service Manual (ESM) for the B17 sedan and C12 hatch lists a “Camshaft Position Sensor (PHASE)” in the Engine Control (EC) section for the MR18DE and MR16DDT engines, and uses its signal for sequential fuel injection, ignition timing, and Continuously Variable Valve Timing (CVTC). This is also echoed in common workshop data sets such as Autodata and Haynes technical references for the MR-series engines.

On a 2016 Pulsar, the camshaft sensor tells the ECU exactly where the intake cam is, so the car can fire injectors and spark at the right moment and trim cam timing for smooth power and good fuel economy. Paired with the crankshaft sensor, it’s the timing heartbeat under the bonnet. When it’s healthy, cold starts are crisp, idle is steady, and shifts are smooth. When it’s not, the car can feel lazy, use more fuel, or throw a check-engine light.

It’s not a scheduled replacement item in Australia or New Zealand, so think of it as “inspect if symptoms appear”. Good oil and filter changes help, because varnish and sludge are enemies of the cam timing system around it. If the sensor does fail, replacement is straightforward for a competent DIYer or any workshop.

• Common symptoms: long crank or no-start, rough idle, flat spots, poor fuel economy, and fault codes like P0340/P0341.
• Quick checks: look for damaged wiring, loose connectors, or oil contamination at the sensor plug.
• Replacement tips: use a quality OEM-equivalent sensor, disconnect the battery, swap the O-ring, and lightly lubricate it before install. Clear codes and perform an idle relearn if required.

On MR18DE Pulsars, the sensor is mounted at the front of the cylinder head near the timing cover, access is usually from the top. The MR16DDT turbo models use a similar sensor layout. Labour time is typically short, but seized fasteners or brittle looms can slow things down on higher-kilometre cars.

If drivability issues crop up, it’s smart to scan first and confirm the fault rather than throwing parts at it. A reliable cam sensor restores proper timing control, protects the catalytic converter by preventing misfires, and keeps the Pulsar feeling perky on the daily commute.

Popular questions about 2016 Nissan Pulsar camshaft sensors

What are the signs my Pulsar’s camshaft sensor is failing?
Expect hard starting (especially warm), intermittent stalling, rough idle, and a check-engine light with codes like P0340 or P0341. Fuel economy can drop and the engine may feel doughy because the ECU can’t phase the cams or time injection properly.

Can a camshaft sensor be cleaned, or does it need replacing?
Minor oil on the tip or connector can be cleaned and the plug reseated, but internal sensor faults or wiring issues won’t be fixed with a wipe. If symptoms persist after checking the loom and connector, replacement is the reliable cure.

Is it safe to keep driving with a camshaft sensor fault?
It may run, but performance and starting can be unpredictable, and misfires risk damaging the catalytic converter. Best bet is to diagnose and sort it sooner rather than later to avoid being stranded and to protect the engine and exhaust hardware.
