Parts for your 2008 Honda Cr-v-Camshaft sensor

2008 Honda CR‑V Camshaft Position Sensor

Based on Honda’s technical literature and parts data, the 2008 Honda CR‑V is fitted with a camshaft position (CMP) sensor and it’s absolutely relevant to engine management. The Honda CR‑V 2007–2011 Service Manual details CMP sensor diagnostics (including DTCs P0340 and P0341) and test procedures, while Honda’s genuine parts catalogues list a dedicated camshaft position sensor for the 2.4‑litre i‑VTEC engine used in this model year. These factory sources confirm the CMP sensor is standard equipment and a critical PCM input on the 2008 CR‑V.

What does it do? The CMP sensor tracks the camshaft’s position relative to the crankshaft so the powertrain control module can fire the injectors sequentially, command variable valve timing (VTC), and time ignition precisely. It’s especially important for reliable cold starts, crisp throttle response, smooth idle, good fuel economy, and low emissions. On the 2008 CR‑V’s chain‑driven DOHC engine, the CMP sits at the cylinder head near the timing chain end, reading a trigger on the cam.

It’s not a routine “wear” item, but it does live a hard life under the bonnet—heat, oil vapour, and vibration. Most issues stem from a tired sensor, an oil‑swollen O‑ring, or wiring/connector damage. When the CMP goes off, expect hard starting or a no‑start, rough idle, flat spots, poor economy, and a check engine light. Scan tools typically show codes like P0340/P0341, and VTC performance can suffer.

Replacement and care are straightforward for most home mechanics. Under the bonnet, disconnect the battery, unplug the connector, remove the small retaining bolt, and ease the sensor out, taking care not to nick the O‑ring land. Lightly oil a new OE‑quality O‑ring, seat the new sensor squarely, and tighten to factory spec—don’t overdo it with the spanner. Clear codes and road test. A relearn is usually not required, the PCM recognises the signal straight away. If faults persist, inspect the engine harness for chafing, check the crankshaft sensor signal, and verify timing chain integrity before condemning new parts.

• Tip: Keep the connector clean and latched, green corrosion or loose pins can mimic a failed sensor.
• Use OEM or reputable aftermarket sensors—cheap units can cause intermittent faults.
• If there’s an oil weep at the sensor, replace the O‑ring to prevent future misreads.

Popular questions

Where is the camshaft position sensor on a 2008 Honda CR‑V?

It’s mounted on the cylinder head at the timing chain end, up top under the plastic engine cover. Facing the engine from the front of the vehicle, look towards the driver’s side of the head for a small sensor with a single electrical connector held by a small bolt.

What fault codes point to a bad camshaft sensor?

Common codes are P0340 (CMP circuit) and P0341 (CMP range/performance). Intermittent dropouts can also appear as misfire counts or VTC performance faults. Always check wiring and the crank sensor signal too—a crank sensor issue can masquerade as a CMP fault.

Does the 2008 CR‑V have one or two cam sensors?

This model’s 2.4‑litre i‑VTEC typically uses a single camshaft position sensor on the intake cam, with the crankshaft position sensor providing the complementary signal. Always verify by VIN and engine code if unsure, as regional variants can differ.
