Parts for your 2015 Nissan Pulsar-Crank angle sensor

2015 Nissan Pulsar crank-angle sensor (crankshaft position sensor)

Technical sources confirm the 2015 Nissan Pulsar does use a crank-angle sensor (commonly called the crankshaft position sensor). Nissan’s factory service information for the C12/B17 Pulsar/Sentra platform (EC—Engine Control section for MR18DE and MR16DDT engines) details the sensor’s role and diagnostics. Industry references such as Autodata’s engine management data for the 2015 Pulsar, and Nissan’s OBD-II fault set including DTCs P0335/P0336, also show the sensor is fitted and critical to operation.

For this model, the crank-angle sensor feeds the engine control module with exact crankshaft position and speed. That’s how the ECU times ignition and fuel injection, syncs with the cam sensor, manages variable valve timing, and monitors misfire. If the signal drops out, the Pulsar may crank but not start, or it may stall without warning. It’s one of those small parts that keep everything running sweet as.

There’s no scheduled kilometre-based servicing for the sensor itself, it’s a sealed, solid-state unit. As part of routine servicing, it’s smart to give the wiring and connector a look—heat, oil seepage, or road grime can cause intermittent faults. Typical symptoms owners notice include hard starting when hot, random stalling, rough idle, a dead tachometer, poor fuel economy, and a check engine light with codes like P0335/P0336.

Replacement is straightforward but benefits from a methodical approach. The sensor is mounted low on the engine—on MR18DE and MR16DDT variants it’s near the transmission bellhousing, some 1.6-litre variants place it near the crank pulley. Disconnect the battery, unplug the connector, remove the retaining bolt, and draw the sensor out. A light smear of clean engine oil on the new O-ring helps it seat. Refit and tighten to the manufacturer’s spec, then clear codes and perform any required idle/throttle relearn using a scan tool. If a spec sheet isn’t on hand, consult the Nissan service manual for torque and relearn steps.

Quality matters here. A genuine or reputable-brand sensor matched to the VIN saves grief with signal quality and fit. If a no-start or stall is present, prioritise diagnosis—don’t keep driving if it’s cutting out, as that can be unsafe. With good installation and intact wiring, the replacement should be a fit-and-forget fix for many years and kilometres.

• Common faults: heat-soak failures, oil contamination at the connector, damaged loom near the bellhousing.
• Handy checks: scan for P0335/P0336, inspect connector pins, wiggle-test the harness, verify crank signal with live data.

Popular questions about the 2015 Nissan Pulsar crank-angle sensor

Where is the crank-angle sensor on a 2015 Pulsar?
On MR18DE and MR16DDT engines it’s mounted low at the gearbox bellhousing side of the block. Some 1.6-litre variants place it at the front of the engine near the crank pulley. Access is usually from underneath, use proper supports if raising the car.

What are the symptoms of a failing crank-angle sensor?
Hard starting (especially hot), sudden stalling, rough idle, misfire feel, poor economy, and an illuminated check engine light. A scan often shows P0335 or P0336. Intermittent heat-related cut-outs are classic.

Does the crank-angle sensor need regular servicing?
No set service interval. It’s checked when diagnosing driveability faults. During routine servicing, a quick inspection of the connector and loom for oil leaks, corrosion, or chafing is worthwhile.
