2014 Honda CR‑V Camshaft Sensor: What It Does, Why It Matters, and When to Replace It

Technical sources confirm the 2014 Honda CR‑V is fitted with a camshaft position sensor (CMP). Honda’s 2012–2014 CR‑V service manual (Engine Electrical—CMP Sensor diagnostics and DTCs P0340/P0341) and the Honda parts catalogue listing for “Sensor Assy., Cam (37510‑R40‑A01)” both identify this sensor on the K24‑series engine. That makes the camshaft sensor absolutely relevant to any servicing under the bonnet.

On the 2014 CR‑V, the camshaft sensor tells the engine control unit exactly where the camshaft sits in relation to the crank. That live “phase” info lets the ECU fire the injectors and spark at the right moment and command the i‑VTEC/VTC system to adjust valve timing for smooth idle, solid mid‑range pull, better fuel economy, and cleaner emissions. Lose that signal and the ECU falls back to guesswork, which is why a crook sensor can mean hard starts, rough running, and the dash lit up like a Christmas tree.

It’s not a scheduled service item, but it’s smart to give it a once‑over whenever the rocker cover area is accessible—say at plug changes. Check the 3‑pin connector for corrosion, oil wicking in the loom, and the sensor’s O‑ring for weeps. A light film of dust is normal, soaked in oil or coolant is not. Avoid blasting the area with a pressure washer—moisture intrusion is a common culprit.

Replacement is straightforward home‑mechanic gear if diagnosed faulty. Disconnect the battery negative, unplug the connector, remove the single 10 mm retaining bolt, twist and withdraw the sensor. Fit a fresh O‑ring lightly oiled, seat the new sensor, and tighten the bolt to about 10 N·m. Clear the fault codes and perform an idle relearn if required. Quality matters here—genuine or reputable OEM‑spec sensors tend to play nicest with Honda’s timing strategy.

Worth noting: if a cam correlation code returns after replacement, the root cause might be elsewhere—stretched timing chain, gummed‑up VTC actuator, or wiring damage. That’s why proper diagnostics (scope or live data for cam/crank sync) beats throwing parts.

• Common symptoms of a failing CMP on a 2014 CR‑V:
  • Hard starting or stalling after start
  • Rough idle, hesitation, or flat spots
  • Poor fuel economy and reduced power
  • Check Engine light with P0340/P0341/P0344
• Quick tips:
  • Inspect connectors and harness near the timing end under the bonnet
  • Replace the O‑ring any time the sensor comes out
  • Don’t ignore misfires—unburnt fuel can hurt the cat converter

FAQs

Where is the camshaft sensor on a 2014 Honda CR‑V?
It’s mounted on the cylinder head at the timing chain end, under the plastic engine cover. Most Aussie/NZ K24 variants use an intake cam sensor (“Sensor A”). Some models may also have an exhaust cam sensor (“Sensor B”). Look for a small sensor secured by one 10 mm bolt with a 3‑pin plug.

Does the camshaft sensor need regular servicing?
There’s no set replacement interval. During routine services (for example around 100,000 km and beyond), it’s wise to check the connector for corrosion, make sure the harness isn’t chafing, and renew the O‑ring if any oil seepage is spotted.

Is it safe to drive with a faulty camshaft sensor?
The CR‑V may still run, but it can be hard to start, go into limp mode, or misfire. Driving like that risks catalyst damage and can leave the driver stranded. Best to diagnose promptly and replace the sensor if it’s the confirmed cause.
