Parts for your 2007 Honda Elysion-Camshaft sensor

2007 Honda Elysion camshaft sensor — purpose, care, and replacement

Based on Honda’s technical literature and parts data, the 2007 Honda Elysion does use a camshaft position sensor (CMP). The Honda Elysion’s K24A 2.4-litre four-cylinder and J-series V6 engines are managed by PGM-FI and i-VTEC systems that rely on both crank and cam position inputs. Honda service manuals for these engines, along with Honda’s Electronic Parts Catalogue for Elysion RR-series models, list the CMP sensor as a defined engine control component.

On this Elysion, the camshaft sensor tells the ECU exactly where the camshaft sits relative to the crank. That live timing info lets the ECU fire injectors and ignition at the right moment and adjust i-VTEC/VTC for smooth idle, decent fuel economy, and proper pull through the rev range. If the sensor signal goes off, the ECU can’t reliably phase valve timing, so it may fall back to a safe map, throw a warning, and make the van feel a bit doughy.

There’s no scheduled replacement interval for a CMP sensor, but it’s smart to check it whenever servicing the ignition system or chasing an intermittent stall or hard-start. Typical clues include a MIL/Check Engine light (often a P0340/P0341-type code), rough idle when warm, sluggish take-off, or longer cranking when hot. V6 variants may have a sensor per bank, so a fault can be bank-specific.

Replacement is reasonably straightforward for a competent home mechanic. Access varies a touch between the K24A and the V6, but the basics hold:

• Park safely, let the engine cool, and disconnect the negative battery terminal.
• Remove any engine covers for access under the bonnet and unplug the sensor connector.
• Undo the retaining bolt, then twist and lift the sensor out, mind the O-ring.
• Lightly oil a new O-ring, seat the new sensor, refit the bolt, and tighten to factory spec.
• Reconnect, clear codes, and road test across a few kilometres to confirm no return of faults.

Most failures are due to heat and age, or wiring chafes. Before buying a sensor, a quick visual of the harness and connector for oil ingress, broken clips, or green corrosion can save coin. Using a quality OEM-equivalent sensor helps avoid repeat dramas, and ensuring the O-ring seals properly keeps stray oil from wicking into the plug. A workshop with a scan tool can confirm live cam/crank correlation and finalise any ECU relearn after the job.

Popular questions

Does a 2007 Honda Elysion actually have a camshaft sensor?
The 2007 Elysion does have a camshaft position sensor. Honda service manuals for the K24A and J-series engines, plus the Honda Electronic Parts Catalogue for Elysion RR models, identify the CMP sensor as part of the engine management system.

What symptoms point to a failing camshaft sensor on an Elysion?
Owners commonly report a Check Engine light, longer cranking when warm, uneven idle, flat spots, and reduced fuel economy. The ECU may log cam correlation faults and limit performance to protect the engine until the signal is reliable again.

Is it safe to keep driving if the camshaft sensor is playing up?
It will often still run, but it’s not ideal. The engine can stall at low speed or refuse a hot restart, which isn’t fun in city traffic. Sorting it promptly avoids getting stranded and helps prevent collateral issues from repeated misfires.
