Parts for your 2010 Nissan Pathfinder-Crank angle sensor

2010 Nissan Pathfinder crank angle sensor — what it is, where it lives, and when to sort it

Referencing the Nissan R51 Pathfinder Factory Service Manual (Engine Control section) and major parts catalogues from NGK/NTK and Bosch, the 2010 Nissan Pathfinder is definitely fitted with a crank angle sensor — Nissan labels it the Crankshaft Position Sensor (CKP). It’s present across the common 2010 engines, including the VQ40DE 4.0 petrol V6, VK56DE 5.6 petrol V8, and the YD25DDTi 2.5 turbo‑diesel. So yes, it’s relevant to this model and it’s a key input for the engine computer.

On a 2010 Pathfinder, the crank angle sensor tracks crankshaft speed and position so the ECU can fire injectors and spark with pinpoint timing. Lose that signal and the engine may crank but won’t start, get a flaky signal and you’ll cop stalling, misfires, or rough running. It also helps with diagnostics by flagging faults like P0335/P0336 when the signal goes missing or out of range.

This sensor isn’t a routine “service item”, but it pays to give it a look when the vehicle’s up on the hoist. Check the connector for corrosion, oil wicking in the loom, or a bent retaining tab. On the VQ40DE and VK56DE it’s typically mounted low at the rear of the engine near the bellhousing, on the YD25 it’s likewise positioned to read a reluctor at the flywheel. Oil leaks from the rear main or spills during servicing can contaminate the plug and O‑ring, so a quick clean and a new O‑ring if it’s weeping is smart.

Replacement is straightforward: disconnect the battery, unplug the connector, remove the retaining bolt, twist the sensor gently to free the O‑ring, and swap it out. Lightly oil the new O‑ring, seat the sensor square, and nip the bolt to factory spec. Clear any fault codes and take it for a decent drive. No special programming is usually needed, if the idle’s a bit off after battery disconnect, perform an idle learn per the service manual.

• Common symptoms: long crank/no start, random stalling, intermittent misfire, limp behaviour, and the MIL on with P0335–P0339.
• Best practice: use an OE‑quality sensor, inspect the harness for rub‑through near the back of the engine, and keep oil leaks in check.

Look after the wiring and sealing, and the CKP on a 2010 Pathfinder will typically run for years without drama.

Popular questions about 2010 Nissan Pathfinder crank angle sensors

Does a 2010 Pathfinder actually have a crank angle sensor?
Yes. Nissan calls it the Crankshaft Position Sensor (CKP), which is effectively the same thing. Technical references like the Nissan Factory Service Manual and major aftermarket catalogues list it for the 2010 VQ40DE, VK56DE, and YD25DDTi engines.

Where is the crank angle sensor on a 2010 Pathfinder?
It’s mounted low at the rear of the engine reading a reluctor on the crank/flywheel. On the VQ40DE and VK56DE petrols, expect it near the bellhousing under the vehicle. On the YD25 diesel, it’s also at the transmission end. Access is usually from underneath with the splash shield off.

Do I need programming after replacing the sensor?
Typically, no. Fit the new sensor, clear fault codes, and road‑test. If the idle is unstable after a battery disconnect, perform the idle learn procedure as outlined in the service manual. Always fix any wiring or connector issues first.
