Parts for your 2015 Honda Cr-v-Camshaft sensor

2015 Honda CR‑V camshaft sensor: purpose, servicing and common questions

Per Honda’s 2015 CR‑V Service Manual for the K24W “Earth Dreams” 2.4‑litre engine and the Honda genuine parts catalogue, this model is fitted with camshaft position sensors — in fact, two of them: CMP Sensor A (intake) and CMP Sensor B (exhaust). They’re essential to how the engine starts, runs and manages variable valve timing, so the camshaft sensor is absolutely relevant on a 2015 Honda CR‑V.

The camshaft sensor’s job is to tell the engine control unit exactly where the camshafts are in relation to the crankshaft. With that info, the ECU can fire the injectors sequentially, spark the plugs at the right moment, and command the i‑VTEC/VTC gear to advance or retard the cams for smooth torque and better fuel economy. On this CR‑V, each sensor is a solid‑state Hall‑effect unit reading a trigger wheel on the cam. If a sensor signal drops out or goes skew‑whiff, you can get hard starting, rough idle, flat spots, poor fuel use and warning lights.

There’s no routine “service” for these sensors — they’re sealed components — but they do benefit from basic care during regular servicing. Under the bonnet, make sure the wiring looms to both CMP sensors aren’t rubbing on brackets and the connectors are clean, locked and dry. Oil leaks from the rocker cover can wick into connectors, so fix leaks promptly and clean the plug faces. If you’re chasing a check‑engine light with codes like P0340/P0341 (intake) or P0365/P0366 (exhaust), inspect the harness and connectors first before condemning the sensor.

Replacement is straightforward DIY for a confident owner, or a quick job for any workshop. Expect to remove the plastic engine cover, unplug the sensor, undo a single small retaining bolt, and withdraw the sensor with its O‑ring. Fit a new O‑ring, lightly oil it, seat the new sensor squarely, and tighten the bolt to the factory spec. Reconnect, clear codes with a scan tool, and let the ECU relearn with a short drive cycle. Always use quality OEM‑equivalent parts — cheap copies can give flaky signals and repeat faults. If access is tight, allow the engine to cool, keep grit out of the sensor bore, and never tug the wiring to remove the plug.

• Typical signs of a failing CMP: long crank, intermittent stall at idle, limp mode, poor fuel economy, and the MIL on with the codes noted above.
• Typical locations: both sensors mount on the cylinder head near the timing chain end, one serves the intake cam, the other the exhaust cam.

Does a 2015 Honda CR‑V have a camshaft position sensor?
Yes. The 2015 CR‑V’s K24W engine uses two camshaft position sensors — CMP A (intake) and CMP B (exhaust). Honda’s service literature and parts listings identify both sensors as required inputs for sequential injection, ignition timing and i‑VTEC/VTC control.

Where is the camshaft sensor on a 2015 CR‑V, and is it easy to replace?
Both sensors sit on the cylinder head near the timing chain cover end — one watching the intake cam, the other the exhaust cam. With the engine cover off, they’re typically a one‑bolt swap each. Most home mechanics can handle it with a 10 mm socket and care, a workshop will usually knock it over in well under an hour.

What symptoms or fault codes point to a bad camshaft sensor on this model?
Common clues include longer cranking, rough or hunting idle, hesitation, reduced power, worse fuel use, and the MIL on. Scan tools often show P0340/P0341 (cam position sensor A – intake) or P0365/P0366 (cam position sensor B – exhaust). Always check wiring and connectors before replacing the sensor itself.
