2006 Honda Accord Camshaft Sensor — purpose, fitment, and service advice

Yes, the 2006 Honda Accord uses a camshaft position sensor. Technical references, including the Honda Accord 2003–2007 Factory Service Manual (Engine Controls, Fuel & Emissions) and Honda’s electronic parts catalogue, specify a Camshaft Position (CMP) sensor for the 2.4L four‑cylinder (K24) and two CMP sensors (one per bank) for the 3.0L V6 (J30). The Engine Control Module relies on CMP and crank signals for sequential injection, VTC/VTEC control, and spark timing, so it’s very much a relevant, fitted component on this model.

On the K24 four‑cylinder, the CMP sensor sits on the cylinder head at the timing‑chain end. On the J30 V6, each cylinder bank has its own CMP sensor mounted near the cam sprockets. The sensor’s job is to tell the ECU exactly where the camshaft is in its rotation, so it can fire injectors and ignition with proper timing and manage valve timing hardware. When it goes out of whack, starting can be slow or it may not start at all, idle can be rough, fuel consumption goes up, and the dash may light up with a Check Engine Lamp and codes like P0340 or P0341.

There’s no scheduled replacement interval for the CMP sensor, it’s a replace‑on‑failure item. That said, a bit of preventative care during servicing helps. Check the connector for corrosion or oil intrusion, make sure the harness isn’t rubbing through under the bonnet, and keep an eye out for oil leaks that can wick into the plug. If replacement is needed, it’s a straightforward driveway job for many owners:

• Disconnect the battery negative terminal to be safe.
• Locate the sensor on the head (two on the V6), unplug the connector, and remove the retaining bolt.
• Swap the sensor, fit a fresh O‑ring lightly oiled, seat it squarely, and tighten the bolt snugly to the service‑manual spec.
• Reconnect the plug and battery, clear any codes, and confirm a clean restart.

Genuine or high‑quality aftermarket sensors both work, but sticking with known brands saves headaches. If a code returns, don’t forget to inspect the wiring, ECU grounds, and—on higher‑kilometre cars—the timing components, because a stretched chain or misaligned reluctor can mimic a bad sensor.

Popular questions

Where is the camshaft sensor on a 2006 Accord?
On the 2.4L four‑cylinder, it’s on the cylinder head at the timing‑chain end, easy to spot by its small plug and single retaining bolt. On the 3.0L V6, there’s one sensor on each cylinder bank near the cam sprockets, accessed from the front of the engine bay.

Can you drive with a bad camshaft sensor?
Sometimes the car will still run, but it may crank longer, run rough, drop into limp mode, or stall. It’s best not to keep driving, as poor timing can increase fuel use and stress other components. Sort it promptly to avoid being stranded.

Are the four‑cylinder and V6 sensors the same?
They’re different part numbers and locations. The four‑cylinder uses one sensor, the V6 uses two. When ordering, match the engine type and VIN to ensure the correct sensor and connector style.
