Parts for your 2016 Honda Accord-Camshaft sensor

2016 Honda Accord camshaft sensor — purpose, servicing and replacement

Technical sources confirm the 2016 Honda Accord is fitted with camshaft position sensor(s). The Honda Service Manual for this generation documents CMP diagnostics (including DTCs P0340–P0344 and P0365–P0369), test procedures and replacement steps. Honda’s electronic parts catalogue lists “Sensor, Camshaft Position” for both the 2.4‑litre inline‑four and 3.5‑litre V6 variants, and workshop wiring diagrams show dedicated CMP signal, ground and reference circuits. On that basis, the camshaft sensor is absolutely relevant to the 2016 Accord.

On this model, the camshaft sensor works with the crankshaft sensor to tell the engine computer exactly where the cam(s) are. That info is used to time fuel injection, spark, and the variable cam timing system (VTC). The result is smooth starting, tidy idle, crisp throttle response and good fuel economy. Lose that signal and the Accord can be hard to start, run rough, feel a bit gutless, or throw a Check Engine Light.

It isn’t a routine replacement item, but it does benefit from sensible servicing checks under the bonnet. During regular oil changes, a quick look for oil wicking into the connector, brittle loom tape, or a loose retaining bolt goes a long way. Clean, correct oil is important too, sludgy oil can upset cam control and trigger CMP‑related fault codes even when the sensor itself is fine.

• Common symptoms of a crook CMP: extended cranking, misfires at idle, poor fuel use, intermittent stalling, and fault codes P0340/P0341 (I4) or P0365/P0366 (V6).
• Basic checks: scan live data for cam/crank sync, inspect the connector pins for corrosion, verify 5‑volt reference and ground, and check harness routing isn’t rubbing through.
• Replacement tips: use a quality sensor with a fresh O‑ring, lightly oil the seal, seat it squarely, and tighten the retaining bolt to workshop‑manual spec. Clear codes, perform an idle learn, and road‑test.

Location-wise, the 2.4L typically has its cam sensor mounted on the cylinder head near the timing chain end. The V6 uses sensors on each bank (labelled A/B in service info). Access is generally straightforward with basic hand tools, making it a no‑dramas job for a competent home mechanic or a quick turn‑around for a workshop.

If CMP codes keep returning, don’t just throw parts at it. Check engine oil condition, timing chain stretch data, VTC operation and the wiring — the sensor often cops the blame for issues upstream.

Popular questions about the 2016 Honda Accord camshaft sensor

Where is the camshaft sensor on a 2016 Accord?
The 2.4‑litre four usually has the sensor at the timing chain end of the head, under the plastic engine cover. The 3.5‑litre V6 has sensors on each cylinder bank, accessible near the cam covers. Exact spot can vary slightly by engine code, so a quick glance at a service diagram helps.

What are the signs the camshaft sensor is failing?
Owners often see a Check Engine Light, longer cranking, a lumpy idle, flat spots on acceleration and worse fuel use. Scan tools commonly show DTCs like P0341 or P0365. If the loom or connector is oily or damaged, fix that before replacing the sensor.

Can the camshaft sensor be cleaned or must it be replaced?
If the issue is minor oil contamination on the connector, a careful clean can restore proper contact. If the sensor’s internal electronics are failing or it’s cracked, replacement is the go. Always rule out wiring faults before fitting a new part.
