Parts for your 2000 Nissan Pulsar-Crank angle sensor

2000 Nissan Pulsar crank-angle sensor: what it does and when to replace it

Based on Nissan factory service manuals and service bulletins for the N15 (’99–’00) and N16 (from 2000) Pulsar, a crank-angle sensing system is absolutely used on the 2000 Nissan Pulsar. Nissan literature refers to it as either a crankshaft position sensor (CKP) on QG-series engines (N16) or an optical crank angle/cam position sensor within the distributor on GA16/SR20 engines (late N15). See: Nissan Pulsar N15/N16 Factory Service Manual, EC section, and Nissan service bulletins covering CKP/CMP sensor faults on early-2000s QG engines.

The crank-angle sensor’s job is to tell the ECU exactly where the crank is in its rotation so the engine can fire injectors and spark at the right time. On N16 QG engines, it’s a dedicated CKP sensor at the bellhousing, working with a cam sensor on the timing cover. On late N15 models, the optical sensor sits inside the distributor and provides both position and phase information.

For owners and workshops looking after a 2000 Pulsar, it’s a small part that does a big job. When it goes out of spec you might see hard starting, random stalls at the lights, a dead tach for a split second, or a check-engine light with codes like P0335/P0340. Fuel economy can go to custard and the car can feel flat.

• N16 (QG engines): The CKP lives on the gearbox bellhousing. Replacement is straightforward—disconnect the battery, unplug the sensor, remove the single bolt, swap it, lightly oil the O-ring, and refit. Clear codes and perform an idle learn if needed. It’s smart to check the cam sensor too, they often age together.
• N15 (GA/SR engines): The “crank angle sensor” is built into the distributor. If it fails, most workshops replace the distributor assembly rather than rebuild the optical module. Set base timing as per the manual after fitment.

There’s no set interval to replace these—treat them as “when required” items. As preventive care during servicing, keep connectors clean and dry, inspect for oil wicking in the loom, and scan for stored misfire or timing codes. Genuine or high-quality aftermarket sensors tend to be the most reliable. A quick road test with live data to confirm stable RPM and cam/crank sync is time well spent.

Popular questions

Does a 2000 Nissan Pulsar have a crank angle sensor?
Yes. On N16 models (from 2000), it’s a separate crankshaft position sensor. On late N15 models that overlap the 2000 year, the crank angle function is inside the distributor as an optical sensor. Both provide the ECU with engine position so it can time spark and fuel properly.

Where is the crank-angle/position sensor on a 2000 Pulsar?
On N16 QG engines it’s mounted at the transmission bellhousing, low on the engine, held by a single bolt. On late N15 GA/SR engines, the crank-angle sensing is part of the distributor on the end of the cam—there isn’t a separate CKP on the bellhousing.

What symptoms point to a failing crank-angle sensor?
Intermittent no-start, sudden stalls, rough idle, hesitation, a flickering or dead tacho moment, and a check-engine light with codes like P0335 or P0340. If symptoms are intermittent, heat soak and vibration testing during diagnosis can help provoke the fault.
