Parts for your 2000 Nissan Pathfinder-Crank angle sensor

2000 Nissan Pathfinder crank angle sensor — what it is, where it lives, and how to look after it

Based on technical sources, the 2000 Nissan Pathfinder (R50, VG33E 3.3‑litre V6) does use a crank angle sensing system. The Nissan Factory Service Manual (EC – Engine Control section) specifies both a Crankshaft Position Sensor (often called REF/POS) mounted at the transmission bellhousing, and a Camshaft/Distributor angle sensor (PHASE) built into the distributor. Nissan parts catalogues for the 2000 Pathfinder list a crankshaft position sensor for the VG33E, and Nissan service literature details fault codes such as P0335/P1336 relating to this sensor. Put simply: a crank angle sensor is fitted and relevant on this model.

On a 2000 Nissan Pathfinder, the crank angle sensing setup tells the ECU exactly where the crankshaft is and how fast it’s spinning. That’s crucial for spark timing, fuel injection, and misfire detection. If the signal drops out, the Pathfinder can crank but not start, stumble, or cut out once warm. It’ll usually throw a check‑engine light with codes like P0335 or a related sync error.

Nissan’s VG33E uses two angle inputs. The crankshaft position sensor sits at the back of the engine by the bellhousing, reading a trigger on the flywheel/flexplate. The cam angle signal is inside the distributor. People often call either of these the “crank angle sensor”, but the no‑start and random cut‑out issues are commonly the crank sensor at the bellhousing.

There’s no scheduled replacement interval, but after a couple of hundred thousand kilometres, heat and vibration can make the sensor or its connector a bit flaky. During regular servicing, it’s smart to eyeball the rear of the engine for damaged loom clips or oil contamination, make sure the sensor connector is snug, and keep the bellhousing area clean. A dab of dielectric grease on the connector pins can help keep moisture at bay.

Replacement is straightforward with basic tools under the bonnet:

• Disconnect the battery, unplug the sensor, remove the single retaining bolt, and wiggle the sensor out.
• Lightly oil the new O‑ring, seat the new sensor, and snug the bolt (about 8 N·m). Don’t over‑tighten.
• Clear any codes, then road‑test. If it still plays up, check the distributor (cam angle) and harness.

Quality matters here. A genuine or reputable OEM‑equivalent sensor tends to be more reliable than a bargain option. If the ECU’s seeing a clean, consistent crank signal, the Pathfinder will start sharply, idle smoothly, and use fuel the way it should.

Popular questions about the 2000 Nissan Pathfinder crank angle sensor

Where is the crank angle/crankshaft position sensor on a 2000 Pathfinder?
It’s mounted at the rear of the engine on the transmission bellhousing, usually accessed from up top at the back of the engine bay or from underneath. Look for a small sensor with a single bolt and a two‑pin plug. The separate cam angle signal lives inside the distributor.

What fault codes point to a bad crank angle sensor?
Common ones are P0335 (Crankshaft Position Sensor “A” circuit) and sometimes a sync‑related code like P1336. Intermittent stalling with no code can still be a failing sensor or a dodgy connector, so live‑data checks help confirm.

Can the crank angle sensor be cleaned, or does it need replacing?
You can wipe off external grime and ensure the connector is clean and tight, but internal sensor failures aren’t fixable. If the signal drops out when hot or shows erratic RPM in scan data, replacement is the go.
