Parts for your 2016 Nissan Pulsar-Crank angle sensor

2016 Nissan Pulsar crank angle sensor (crankshaft position sensor)

Yes, the 2016 Nissan Pulsar is fitted with a crank angle sensor, more formally the crankshaft position (CKP) sensor. Nissan’s Factory Service Manual for the Pulsar/Sylphy (C12 hatch and B17 sedan) in the Engine Control (EC) section identifies the CKP sensor as a key input for engine management on MR18DE and MR16DDT engines. Nissan’s parts catalogues for these models also list a dedicated crankshaft position sensor and associated harness, confirming its use.

On the 2016 Pulsar, the crank angle sensor reads a toothed wheel on the crankshaft and sends a precise pulse signal to the ECM. That signal lets the ECM know exactly where the crank is in its rotation and how fast it’s spinning. The ECM then times fuel injection and spark events to suit conditions, delivering smooth starts, clean idle, decent fuel economy and proper power. If that signal drops out or goes noisy, the engine can misfire, stall, crank for ages, or not start at all. The check engine light will usually join the party, often with codes like P0335–P0339.

There’s no scheduled replacement interval for the Pulsar’s crank angle sensor — it’s a “replace on failure” item. That said, it’s smart to give it some love during routine servicing:

• Inspect the sensor connector and loom for brittle insulation, chafing or oil contamination.
• Keep an eye out for crank seal or sump leaks that can wet the sensor — oil and grit are its enemies.
• If the engine has intermittent stalling or long crank times, scan for CKP-related fault codes before throwing other parts at it.

Replacement is typically straightforward: battery off, unplug the connector, remove the retaining bolt, ease the sensor out, lightly lube the O-ring on the new unit, fit and reconnect. Access on the Pulsar is generally from underneath at the transmission end of the engine block, so a hoist or solid stands make life easier. After replacement, clear any stored codes and confirm crank signal and idle quality with a scan tool. Using a quality OEM-equivalent sensor helps avoid headaches with signal quality and hot-soak behaviour.

Whether it’s the everyday MR18DE or the punchy MR16DDT SSS, the Pulsar relies on this little sensor for spot-on timing. If it’s acting up, it’s worth sorting promptly — the difference in drivability is night and day.

• Common symptoms of a failing CKP: hard starting, sudden stalls, tachometer drops to zero, poor fuel economy, and a MIL with P0335-series codes.
• Good practice: pair sensor checks with grounds and battery health — weak voltage can mimic sensor faults.

Popular questions

Where is the crank angle sensor on a 2016 Nissan Pulsar?
It sits low on the engine near the gearbox bellhousing, reading the crankshaft reluctor. On both C12 hatch and B17 sedan, access is usually from underneath the car. Look for a small two-wire or three-wire sensor secured by a single bolt into the block.

If space is tight, removing the engine undertray and working with proper support stands will make the job much easier.

Does the crank angle sensor need regular servicing?
There’s no set service interval. It’s generally left alone until there’s a fault. During routine servicing, check for oil leaks above it, make sure the connector is clean and clipped firmly, and verify there are no stored CKP codes.

If the sensor is contaminated by oil or the wiring is damaged, fix the leak and replace the sensor rather than trying to “clean” a failing unit.

Is it safe to drive with a bad crank angle sensor?
If it’s intermittent, the car may still run but can stall without warning or refuse to restart when hot — not ideal in Aussie or Kiwi traffic. If the ECM loses the crank signal altogether, it won’t start at all.

Best bet is to get it diagnosed promptly. A quick scan and a sensor swap, if required, usually restores reliable starting and smooth running.
