Parts for your 2013 Nissan Pathfinder-Crank angle sensor

2013 Nissan Pathfinder crank-angle sensor: what it does and how to look after it

Yes, the 2013 Nissan Pathfinder (R52, 3.5‑litre VQ35DE) is fitted with a crank‑angle sensor, more formally the crankshaft position sensor (CKP). This is confirmed by Nissan’s Electronic Service Manual (ESM) for the 2013 Pathfinder R52 in the Engine Control (EC) section under “Crankshaft Position Sensor (POS),” the factory DTC listings for P0335/P0339, and the Nissan parts catalogue group 23731 (Sensor Assy – Crank) applicable to the VQ35DE engine.

On this Pathfinder, the crank‑angle sensor is the ECU’s timekeeper. It tracks crankshaft speed and exact position so the engine computer can fire the spark and inject fuel at just the right moments. It also helps with misfire detection and smooth starts. If it goes out of whack, expect hard starting, random stalling (often when hot), a rough idle, limited power, and the check engine light. Scan tools commonly show DTCs like P0335 or zero RPM while cranking when the sensor has failed.

It isn’t a scheduled service item, but it’s smart to give it a once‑over during major services. Check the wiring and connector for heat damage, oil contamination, or a loose fit. Because it lives low on the engine near the transmission bellhousing, it can cop grime and splash, keeping that area clean helps. If there are oil leaks above it, sort those to avoid soaking the sensor and plug.

Replacement is straightforward for a competent DIYer or workshop. General guidance:

• Disconnect the battery, safely raise the vehicle, and access the sensor from underneath.
• Unplug the connector, remove the retaining bolt, and gently twist the sensor out.
• Lightly oil the new O‑ring, seat the sensor fully, and tighten the bolt to about 9–10 N·m.
• Clear fault codes and confirm live data shows a stable RPM signal. If the idle is off, perform an Idle Air Volume Learn with a scan tool.

Use a quality part (genuine or reputable aftermarket) and avoid cheapies that drift when hot. If a fresh crank‑angle sensor doesn’t fix a no‑start, check the camshaft sensors and power/earth to the ECU, as they all work together to keep the VQ35DE happy. With the right sensor and a tidy connector, most Pathfinders will rack up plenty more kilometres under the bonnet without drama.

Popular questions

Is a crank‑angle sensor the same as a crankshaft position sensor on a 2013 Pathfinder?
Yes. Nissan labels it the Crankshaft Position Sensor (POS) in the service manual, but in Australia and New Zealand it’s commonly called a crank‑angle sensor. They’re the same part doing the same job.

Where is the crank‑angle sensor on a 2013 Pathfinder?
It’s mounted low on the engine near the transmission bellhousing. Most techs reach it from underneath. Look for a small sensor with a single bolt and a two‑pin plug.

Do I need to program anything after replacing the sensor?
No coding is required. Clear any fault codes, confirm the RPM signal is steady, and if the idle feels off, carry out an Idle Air Volume Learn with a scan tool.
