2017 Honda Accord camshaft sensor — what it does and when to replace it

Yes, the 2017 Honda Accord uses a camshaft position sensor (CMP). Honda’s factory service information for the 2013–2017 Accord (both the 2.4L i‑VTEC inline‑four and the 3.5L V6) details CMP sensor inputs to the ECM/PCM, associated diagnostics (e.g., DTCs P0340/P0341), and wiring checks. OEM parts catalogues for the 2017 Accord also list camshaft position sensors as serviceable components, the V6 has a sensor per bank, while the 2.4L uses a CMP sensor on the cam. These technical sources make it clear the sensor is fitted and integral to engine control.

On a 2017 Accord, the camshaft sensor lets the ECM know exactly where the cam(s) sit relative to the crank. That timing info is crucial for fuel injection sequencing, spark timing, and the i‑VTEC/VTC systems that tweak valve timing for punch and efficiency. If the CMP signal goes missing or skews, the Accord can struggle to start, drop into limp, or throw a Check Engine Light with codes like P0340 or P0341. Fuel economy and drivability can go pear‑shaped too.

It’s not a routine replacement item, but it is absolutely fair game during fault diagnosis or if there’s evidence of damage or oil contamination. Smart servicing on a 2017 Accord includes keeping the engine oil fresh (correct grade and interval), because sludgy oil can upset cam phasers and make the CMP data look ugly. A quick glance under the bonnet for chafed wiring, loose connectors, or oil weeping around the sensor’s O‑ring is time well spent.

• Common symptoms: hard starting, rough idle, hesitation, worse fuel use, intermittent stalling, or i‑VTEC/VTC performance complaints alongside a CEL.
• Location: typically at the end of the cylinder head. The 2.4L has a single CMP on the cam cover area, the 3.5L V6 has one per bank.
• Quick replacement tips: disconnect the battery, use a quality O‑ring, lightly oil the seal, torque to spec from the service manual, keep the connector clean and properly seated, clear codes and road‑test. If a relearn or idle reset is called for, follow the service procedure.
• Don’t shotgun parts: confirm power, ground, and signal with basic electrical tests, and inspect the reluctor/trigger wheel condition via service steps.

When a genuine fault is confirmed, a new CMP sensor is a straightforward fit with hand tools. For many owners, it’s a neat driveway job, otherwise, any reputable workshop in Australia or New Zealand will knock it over quickly and get the Accord back to its smooth, economical best.

Popular questions

Where is the camshaft sensor located on a 2017 Honda Accord?
The 2.4L inline‑four typically has the camshaft sensor mounted at the end of the cylinder head near the cam cover. The 3.5L V6 uses two sensors—one on each bank—accessible near the top/front of the engine. Access is generally under the plastic engine cover after popping the bonnet.

Exact orientation can vary a touch by engine code, so checking the under‑bonnet label and a service diagram helps nail the spot before grabbing a spanner.

What are the symptoms of a failing camshaft sensor on this model?
Expect a Check Engine Light, extended cranking, rough idle, misfires or hesitation, and poorer fuel economy. The ECM may log DTCs such as P0340 or P0341 if the signal is missing or erratic.

If it acts up intermittently, look for heat‑soak faults, oil intrusion in the connector, or a wiring rub through near the cam cover before condemning the sensor itself.

Is it safe to drive with a bad camshaft sensor?
Short term, the car may still run, but performance can be ordinary and it might stall or refuse to restart when hot, which isn’t ideal on a busy motorway. It’s best to diagnose and repair promptly.

The job is typically quick and not overly pricey compared with the hassles of being stranded, and replacing the O‑ring at the same time helps keep oil where it belongs.
