Parts for your 2010 Honda Cr-v-Camshaft sensor

2010 Honda CR‑V camshaft sensor — purpose, servicing tips, and when to replace

Technical sources including the Honda 2010 CR‑V Service Manual (Engine Electrical — Camshaft Position Sensor diagnostics), Honda’s OBD‑II DTC listings for this model, and the Honda parts catalogue confirm the 2010 Honda CR‑V (2.4‑litre K‑series i‑VTEC) is fitted with a camshaft position sensor (CMP). Those factory documents detail tests and fault codes such as P0340, P0341 and P0365, making it clear the CMP is an essential fitted component.

The camshaft sensor keeps the ECU in the loop about where the intake cam is in its rotation. That lets the CR‑V run true sequential fuel injection, fire the plugs at the right moment, and control the i‑VTEC/VTC cam phasing for a smooth idle and decent pull across the rev range. It also speeds up cold starts and helps the ECU detect misfires properly.

It’s not a scheduled replacement item, but it does appreciate a bit of attention during regular servicing. A quick look for oil weeping at the sensor O‑ring, brittle wiring, or a loose connector can save drama later. Because the sensor reads a target on the cam and the engine adjusts valve timing hydraulically, fresh, correct‑grade oil is key — sludgy oil can throw cam timing around and trigger correlation or performance codes that mimic a dud sensor.

Typical complaints when the CMP plays up include hard starting, intermittent stalling, rough idle, flat spots under load, higher fuel use and the check engine light. Common fault codes are P0340/P0341 (CMP circuit/performance) and, on some variants, P0365 (sensor “B”). Correlation codes like P0016 can pop up too, but those often point to timing or oiling issues rather than the sensor itself.

Replacement is straightforward for a home mechanic: disconnect the battery negative, unplug the sensor on the end of the cylinder head, remove the retaining bolt, then twist and pull the sensor free. Lightly oil the new O‑ring, seat the sensor squarely, reinstall the bolt to the workshop‑manual spec, reconnect the plug and battery, then clear any codes and road‑test. Use a quality OEM‑equivalent part to avoid nuisance faults. If the light returns, step through the service‑manual checks for wiring continuity and reference voltages before blaming the new sensor.

• Service tip: Inspect the sensor and connector at each major service or around 100,000 km, and keep oil changes on time.
• If the engine cranks but won’t start, a failed CMP is a candidate — scan it first before replacing parts.

Popular questions about 2010 Honda CR‑V camshaft sensors

Where is the camshaft sensor on a 2010 Honda CR‑V?
On the 2.4‑litre K‑series, the camshaft sensor sits at the end of the cylinder head near the timing chain end. It’s accessible from the top of the engine bay — follow the loom across the head and look for a small sensor with a single retaining bolt and an O‑ring seal.

Access is usually easiest with the engine cover off. Always unplug the connector carefully to avoid cracking the clip, especially on vehicles that have lived in hot climates.

What fault codes point to a bad cam sensor on this model?
Look for P0340 and P0341 (camshaft position circuit/performance). Some variants may also log P0365 for a secondary cam signal. If you see P0016 (crank/cam correlation), don’t jump straight to a sensor — check oil condition, timing chain stretch, and VTC operation first.

A quick live‑data check for a steady cam signal during cranking helps confirm whether the sensor is actually the culprit.

Is it safe to keep driving with a dodgy camshaft sensor?
It might run but can stall, lose power, or refuse to restart when hot. Prolonged misfiring can stress the catalytic converter. It’s generally fine to limp to a workshop, but best to sort it promptly to avoid getting stranded and to keep emissions in check.

If the engine cranks and doesn’t catch, the CMP may be the reason — get a scan and basic checks done before assuming a bigger fault.
