Parts for your 2017 Nissan Pathfinder-Camshaft sensor

2017 Nissan Pathfinder camshaft sensor — what it does and how to look after it

Yes, the 2017 Nissan Pathfinder definitely uses camshaft position sensors. Technical references that confirm fitment include the Nissan Factory Service Manual for the R52 (Engine Control section, which details camshaft position sensors for each bank), Nissan’s parts catalogue listings for the VQ35DD 3.5‑litre V6, and mainstream fitment guides from OEM-equivalent suppliers. These sources align with common OBD2 diagnostics for this model that flag camshaft sensor faults (for example, P0340/P0345) when the sensor or its circuit plays up.

On the 2017 Pathfinder, the camshaft sensor tracks the precise position of the camshaft so the ECU can sync fuel injection, ignition timing, and variable valve timing. With direct injection and variable valve timing on the VQ35DD, clean, accurate cam timing data is crucial for smooth starting, decent fuel economy, and keeping the engine feeling lively under the right foot.

It’s not a scheduled service item, but it’s smart to keep an eye on tell-tales. If a Pathfinder cranks longer than usual, stumbles at idle, drops into limp mode, hesitates under load, or lights the MIL with cam/crank correlation codes, the camshaft sensor (or its wiring/connector) could be on the shortlist.

• Typical issues: intermittent stalling, rough idle, poor fuel use, hard starting, MIL on with cam-related DTCs.
• Quick checks: look for oil in connectors, brittle or rubbed-through wiring, and loose sensor mounting.

Replacement is usually straightforward and DIY‑friendly for a confident home mechanic. The 2017 model typically has two camshaft sensors (one per cylinder bank). Access varies by bank, so set aside time and remove nearby bits as needed for reach. Usual steps are: disconnect the battery, unplug the sensor, remove the single retaining bolt, ease out the sensor, lightly oil the new O‑ring, refit and tighten to factory spec, reconnect and clear codes, then road‑test. A quality OEM or OEM‑equivalent sensor is worth it to avoid ghost faults. If unsure on torque, bank identification, or access, refer to the Nissan workshop manual for the VQ35DD.

Good oil and filter changes help overall valve timing performance, and keeping connectors clean and loom supports intact reduces the chance of intermittent cam sensor errors. If the MIL returns after replacement, scan live data to confirm cam/crank sync and check wiring continuity to the ECU.

Popular questions about the 2017 Nissan Pathfinder camshaft sensor

How many camshaft sensors does a 2017 Pathfinder have?
Most 2017 Pathfinders with the VQ35DD V6 use two camshaft position sensors, one for each cylinder bank. That lets the ECU track valve timing on both sides for accurate fuelling and spark.

Can it be driven with a faulty camshaft sensor?
It might run, but performance can be ordinary—hard starting, poor economy, and limp mode are common. It’s best to diagnose and fix promptly to avoid being stranded and to protect the catalytic converters from misfire damage.

Where is the camshaft sensor located?
They’re mounted on the cylinder heads near the timing cover area, one per bank. Exact access differs by bank and trim. A workshop manual or a quick visual under the bonnet will point out the small, single‑bolt sensor with a two‑ or three‑pin plug.
