Parts for your 2011 Honda Accord-Camshaft sensor

2011 Honda Accord camshaft sensor: what it does and when to sort it

Yes, the 2011 Honda Accord is fitted with a camshaft sensor. Honda’s Factory Service Manual for the 2008–2012 Accord (Engine Controls—CMP Sensor), the Honda Electronic Parts Catalogue for the 2011 Accord (covering 2.4‑litre K24Z and 3.5‑litre J35Z engines), and major repair databases such as ALLDATA and Mitchell1 all list the camshaft position (CMP) sensor as standard equipment. The four‑cylinder uses one CMP sensor, the V6 uses two (one per bank). These sources also document CMP‑related fault codes like P0340/P0341/P0344, further confirming its presence.

On this Accord, the camshaft sensor feeds live camshaft position data to the ECU so it can time fuel injection and ignition precisely, manage i‑VTEC cam phasing, and monitor misfire. If the sensor signal drops out or goes dodgy, the car can struggle to start, run rough, or fall back into a limp strategy with higher fuel use.

There’s no scheduled replacement interval for the camshaft sensor, but it’s smart to inspect it during servicing—especially on higher‑kilometre cars or where there’s evidence of oil weep around the timing cover. Heat cycles, oil contamination, and brittle connectors are the usual culprits. Genuine or high‑quality aftermarket sensors are recommended so the ECU sees a clean, stable signal.

• Common symptoms: long crank, intermittent stalling, uneven idle, flat spots, poor economy, and a check engine light (often with P0340/P0341/P0344).
• Basic checks: look for oil in the plug, damaged wiring, loose fitment, or metal debris stuck to the sensor tip.

Location and replacement tips: on the 2.4‑litre K24Z, the CMP sensor sits at the end of the intake cam near the timing chain side of the head. On the 3.5‑litre J35Z V6, there’s one sensor on each bank near the cam gears. Access is straightforward with basic hand tools.

1. Disconnect the battery and remove the engine cover.
2. Unplug the sensor connector and remove the retaining bolt.
3. Twist the sensor gently to release the O‑ring, then pull straight out.
4. Lightly oil the new O‑ring, install, and tighten the bolt to factory spec.
5. Reconnect, clear any codes, and road test. The ECU may complete a brief relearn.

If faults persist after replacement, check cam timing, crank sensor health, and wiring integrity under the bonnet loom—common places for rub‑through. A quick scope test of the cam and crank signals can save hours of guesswork.

Popular questions about a 2011 Honda Accord camshaft sensor

Where exactly is the camshaft sensor on a 2011 Accord?
On the 2.4‑litre, it’s mounted on the cylinder head at the timing chain end, reading the intake cam. On the 3.5‑litre V6, there are two—one on each bank near the front of the engine. Under the bonnet it’s usually a single small sensor with a two‑ or three‑pin plug and a single 10 mm retaining bolt.

Can they keep driving with a faulty camshaft sensor?
It might still run, but it can be hard to start, lack power, and use more fuel. Prolonged driving risks stalling at awkward moments. Best to diagnose and replace promptly to protect the engine and avoid getting caught out.

What does replacement typically cost in Australia or New Zealand?
Parts range roughly from AUD/NZD $80–$220 depending on brand and engine. Labour is often 0.3–0.7 hour, so drive‑in, drive‑out totals commonly fall between AUD/NZD $180 and $400 at most workshops.
