Parts for your 2014 Nissan Pathfinder-Crank angle sensor

2014 Nissan Pathfinder crank-angle-sensor: what it does and when to replace it

Based on the 2014 Pathfinder (R52) Factory Service Manual – Engine Control (EC) and Nissan technical bulletins addressing DTC P0335 for this model, the vehicle is fitted with a crank-angle-sensor. Nissan typically names it the Crankshaft Position Sensor (CKP or POS), but many techs still say “crank angle sensor”. It’s mounted at the bell housing area and reads a toothed wheel on the crank, giving the ECU a precise picture of crank angle and engine speed.

The sensor’s job is dead simple yet absolutely critical: it tells the ECU exactly where the crank is and how fast it’s spinning. Paired with the cam sensors, it lets the ECU fire spark and inject fuel at the right moment, stabilise idle, and manage start-up. On the Pathfinder’s VQ35DE with CVT, that clean timing signal also helps with smooth take-offs and drivability. If the signal goes walkabout, expect hard starting or no start, rough running, and a dash light party.

Common clues the CKP (crank-angle-sensor) is on the way out include:

• Intermittent stalling or a long crank, especially when hot
• Rough idle or misfire-like feel without obvious coil or plug faults
• Check Engine Light with codes like P0335 or P0339
• Poor fuel economy and hesitant throttle response

It’s not a scheduled service item, so there’s no routine replacement interval. As part of regular servicing, it’s worth giving the wiring and connector a quick look under the bonnet: check for oil contamination, broken locking tabs, chafed loom, and signs of moisture. Avoid blasting the area with a pressure washer, and fix any rocker cover or rear main oil weeps that could soak the sensor over time.

When replacement is needed, it’s a straightforward job for a competent home mechanic with a basic socket set. Disconnect the battery, gain access from the right-hand side near the trans bell housing, unplug the connector, remove the retaining bolt, and ease the sensor out. Lightly oil the O-ring on the new unit, seat it squarely, refit the bolt, and route the loom exactly as it was. Clear the codes, then take a short drive cycle so the ECU can verify a clean signal. Use a quality OEM-equivalent sensor to avoid false triggers and intermittent faults. Most workshops will sort it in under an hour, and it’s far cheaper than chasing misfires that aren’t really there.

Popular questions about the 2014 Nissan Pathfinder crank-angle-sensor

Is the crank-angle-sensor the same as the crankshaft position sensor on a 2014 Pathfinder?
Yes. Nissan’s service literature calls it the Crankshaft Position Sensor (CKP or POS). Many mechanics still say “crank angle sensor”, but they mean the same component that reports crank position and speed to the ECU.

Where is it located and how hard is it to change?
It sits near the transmission bell housing reading the flywheel/flex-plate. Access is typically from the right-hand side of the engine bay or via the wheel arch liner. For most, it’s a 30–60 minute job with basic tools, provided the connector and retaining bolt aren’t corroded.

Should it be replaced as preventative maintenance?
No. It’s a replace-on-failure item. Many last well beyond 150,000 km. During routine servicing, just check the wiring and keep the area clean and dry. If you see related fault codes or hot-start issues, test and replace as needed.
