Parts for your 2017 Nissan Pulsar-Crank angle sensor

2017 Nissan Pulsar crank-angle-sensor (crankshaft position sensor)

Based on technical sources, the 2017 Nissan Pulsar is fitted with a crank-angle sensor, commonly listed by Nissan as the Crankshaft Position Sensor (POS/CKP). Nissan factory service manuals for the Pulsar/Sylphy B17 and Pulsar C13 (Engine Control System, EC section) describe the CKP sensor as a core input for ignition timing, fuel injection sequencing and misfire monitoring, with related DTCs such as P0335–P0339. That makes the crank-angle sensor absolutely relevant to this model.

On a 2017 Pulsar, the crank-angle sensor keeps the engine management on the straight and narrow. It watches the exact position and speed of the crankshaft, so the ECU knows when to spark and when to inject fuel. Whether the car’s running an MR-series 1.8-litre or a DIG‑T variant in other markets, the job is the same: clean, accurate timing signals for smooth starting, stable idle, decent fuel economy and low emissions.

It’s a solid-state, no-service-interval part, so there’s nothing to “maintain” in the traditional sense. During regular servicing, a good workshop will scan for fault codes and look for clues like long crank, intermittent stalling, rough running or the MIL light. If the sensor or its wiring is on the way out, the ECU usually logs a code and the engine may go into a limp strategy or fail to start.

Replacement is straightforward for a trained tech. The sensor is typically bolted to the engine block near the transmission bellhousing, reading a toothed reluctor on the crank. Expect a single retaining bolt and an O‑ring seal. The correct approach is:

• Confirm with diagnostics (live RPM signal, crank/cam correlation, DTCs)
• Inspect wiring, connectors and oil contamination before condemning the sensor
• Fit a quality OEM-equivalent sensor and a fresh O‑ring
• Clear codes and verify a clean RPM signal and stable idle on road test

There’s usually no special relearn required after CKP replacement on these engines, the ECU adapts as it sees stable signals. That said, many workshops will perform basic idle learning and ensure any relevant Nissan self-learn routines are complete. If the Pulsar has been hard to start, stalling when hot, or showing P0335-type codes, it’s worth getting it checked sooner rather than later—driving with a flaky crank-angle signal can end in a no-start under the bonnet at the servo.

• Common symptoms to watch for:
  • Extended cranking or no start, especially when warm
  • Intermittent stalling or rough idle
  • Speedo fine but tach drops to zero during a stall event
  • Check Engine light with CKP-related codes

Q: Where is the crank-angle sensor on a 2017 Nissan Pulsar?

It’s typically mounted low on the engine block at the gearbox side, reading a reluctor on the crankshaft. Access is often easiest from underneath with the splash shield off. Exact placement can vary slightly by engine variant, so a quick look-up in the workshop manual for the specific VIN helps.

Q: Does the crank-angle sensor need routine replacement?

No, there’s no scheduled interval. It’s replaced on condition—usually when diagnostics show no or erratic RPM signal, or DTCs like P0335 appear. A careful check of wiring and connectors is part of the job, as heat and oil can affect the harness over time.

Q: Is it safe to drive with a failing crank-angle sensor?

Not really. A marginal sensor can cause sudden stalling or a no-start. If the Pulsar is showing symptoms or codes, it’s best to get it diagnosed and sorted promptly to avoid getting stranded.
