Parts for your 2022 Nissan X-trail-Camshaft sensor

2022 Nissan X‑Trail camshaft sensor — what it does and when to replace it

Based on Nissan’s Electronic Service Manual (T32, EC section), common engine coverage in Autodata for the 2022 X‑Trail/Rogue, and OE supplier catalogues (Hitachi/Bosch listings for QR25DE, MR20DD and M9R engines), the 2022 Nissan X‑Trail is fitted with camshaft position sensor(s). Depending on engine, there can be one or two sensors (typically one on each cam for intake and exhaust). It’s not a “maybe” part — it’s essential for sequential injection, ignition timing, and variable valve timing control.

In this X‑Trail, the camshaft sensor (often called a CMP sensor) tells the ECU exactly where the cam(s) are in relation to the crank. Paired with the crank sensor, it lets the ECU fire injectors in sequence, light the spark at the right moment, and adjust valve timing for torque, efficiency and emissions. If it goes out of whack, the car can crank a long time, run rough, drop power, or trigger limp mode.

There’s no set service interval for the camshaft sensor — it’s a solid-state, sealed unit. During regular servicing, it’s smart to visually check the wiring and connector under the bonnet for oil contamination, brittle conduit, or loose clips, especially around the front/top of the engine where heat and vibrations are highest. A light mist of oil from a timing cover weep can wick into plugs and cause grief over time.

• Common fault clues: hard starting when warm, uneven idle, poor fuel economy, or the MIL on with codes like P0340/P0341/P0345 (cam signal/correlation).
• Before replacing: scan live data to confirm cam/crank sync, inspect the harness, and check for timing chain stretch or a slipped reluctor if correlation codes persist.
• When replacing: use an OE‑quality sensor (Hitachi/Nissan spec), clean the mating face, lightly lube the O‑ring if fitted, and reconnect the plug firmly. Tighten the bolt to the service‑manual spec and clear codes, then verify cam/crank sync and driveability.

Driving with a dying sensor can cook fuel economy and stress the catalytic converter, so if the light’s on and it’s starting poorly, sort it sooner rather than later. For Aussie and Kiwi conditions, dust and heat are the usual culprits, so keeping connectors clean and loom clips secure is cheap insurance for your 2022 X‑Trail.

Where is the camshaft sensor on a 2022 X‑Trail?

On the petrol engines, they’re typically at the front or top of the cylinder head near the timing cover — often one on the intake cam and one on the exhaust cam. The diesel layout differs slightly but remains on the head near the cam drive. Access is usually straightforward with the engine cover off.

What are the signs the camshaft sensor is failing?

Long crank time, misfires or a lumpy idle, flat spots, worse fuel economy, and the check‑engine light are the big giveaways. A scan will often show codes like P0340/P0341/P0345 and may reveal cam/crank synchronisation issues in live data.

Can it be driven with a faulty sensor?

It might still run, but it can drop into limp mode or stall, and prolonged driving risks catalyst damage from misfires. Best bet is to diagnose and replace promptly, then verify with a road test and a fresh scan.
