2006 Honda Elysion Camshaft Sensor: Purpose, Fitment and Service Advice

Yes — the 2006 Honda Elysion is fitted with a camshaft position sensor (CMP). This applies to both engines offered for that model: the K24A 2.4-litre i-VTEC four-cylinder and the J30A 3.0-litre V6. Honda technical literature that identifies the CMP for these powerplants includes the Honda Elysion RR1–RR4 Service Manual (2004–2008, Engine Electrical/PGM-FI), Honda K24A Engine Workshop/Training material (i-VTEC and VTC control sections), and J-series V6 service information (cam phase input for sequential injection). These sources specify a CMP sensor used for cam phase detection, VTC/VTEC control and OBD-II monitoring.

On the Elysion, the camshaft sensor tells the ECU exactly where the cam is in its rotation, so it can fire the injectors and spark at the right time, manage i-VTEC/VTC, and keep cold starts smooth. It also helps the ECU confirm misfire data and sync up with the crank sensor. On K24A models the CMP sits on the cylinder head at the timing chain end (intake cam side). On J30A V6 variants, bank-specific CMP sensors are used on the heads, with the rear bank most commonly accessed under the upper cover.

There’s no routine replacement interval — the CMP is a “fit and forget” item. Still, a bit of preventative care goes a long way. Keep engine oil fresh and at the right level, sludgy oil can upset VTC operation and lead to rough running that’s often blamed on the sensor. When the bonnet’s up for regular servicing, a quick look for oil weep at the sensor O-ring and a check of the wiring harness near the timing cover is worth it.

• Common signs of a crook CMP: hard starting, rough idle, random stalling, flat spots under load, higher fuel use, and a check engine light (codes like P0340/P0341).
• Before replacing, inspect the connector for corrosion, broken tabs, or oil intrusion, and verify good battery voltage and grounds.

Replacing the Elysion’s CMP is generally straightforward: disconnect the battery, remove the engine cover, unplug the sensor, undo the retaining bolt, and ease it out. Lightly oil a fresh O-ring, seat the new sensor squarely, and tighten the bolt to the service manual spec. Plug it back in, clear any codes, and perform an idle relearn if needed. Choose a quality OEM-spec sensor — it saves chasing gremlins later. If the light pops back on straight away, check harness continuity and cam/crank correlation before calling it done.

Popular questions about 2006 Honda Elysion camshaft sensors

Where is the camshaft sensor located on a 2006 Honda Elysion?
On K24A four-cylinder models, it’s on the cylinder head at the timing chain end, reading the intake cam. On J30A V6 versions, the engine uses bank-specific sensors mounted on the heads, the rear bank sensor is typically the one you’ll see under the upper cover. A quick visual from the top usually spots the connector and a single retaining bolt.

What are the usual symptoms of a failing camshaft sensor on an Elysion?
Owners often notice hard starts, intermittent stalling, rough idle, lack of grunt, and worse fuel economy. The check engine light is common, with codes like P0340 or P0341. Because similar symptoms can come from timing, VTC oil control, or wiring issues, it’s smart to scan, test the harness, and confirm before ordering parts.

Is it safe to drive with a faulty camshaft sensor?
It may run, but it’s not ideal. The ECU can fall back to default strategies that hurt performance and economy, and it may stall at awkward times. Best bet: keep trips short, avoid heavy loads, and sort it promptly to prevent knock-on issues and to keep emissions in check.
