Parts for your 2019 Honda Accord-Camshaft sensor

2019 Honda Accord camshaft sensor — what it does and how to look after it

Yes, the 2019 Honda Accord does use a camshaft position sensor. Honda’s factory Service Information (SIS) and the 2018–2020 Accord workshop manual list camshaft position sensor diagnostics (including DTCs P0340/P0341/P0365), and the Honda parts catalogue shows dedicated camshaft sensors for the 1.5T (L15BE), 2.0T (K20C4) and the hybrid powertrain. On the turbo petrol DOHC engines, there’s typically one sensor for the intake cam and another for the exhaust cam.

This little sensor pulls more weight than its size suggests. It tracks the cam’s exact position, letting the ECU sync fuel injection and spark with the crankshaft signal. That precise timing delivers smooth starts, crisp throttle response, strong efficiency, and reliable VTEC/VTC cam phasing. When it misbehaves, the Accord can struggle to start, run rough, drop into limp mode, or light the check engine lamp.

It’s not a scheduled replacement item, but it’s smart to keep it on the radar during routine servicing. A quick visual once-over of the sensor body and plug, checking for oil wicking into the connector or brittle wiring near hot areas, goes a long way. Fresh, correct-spec engine oil is key too, sludgy oil can upset cam phasers and make the sensor’s job harder.

• Common clues it’s unhappy: hard starting, erratic idle, flat performance, higher fuel use, and fault codes like P0340/P0365.
• Basic checks first: connector seated firmly, no bent pins, no oil intrusion, and harness not rubbing under the bonnet.

Replacement is straightforward for most variants: disconnect the battery, unplug the sensor, remove the retaining bolt, swap the sensor and O-ring, then refit and tighten to factory spec (many Honda CMP bolts are around 9–10 N·m, confirm in SIS). Clear any codes and take a short drive so the ECU can re-sync. Genuine or high-quality aftermarket parts help avoid nuisance correlation faults.

If the light’s on, it’s worth scanning before throwing parts. A failing crank sensor, stretched timing, or oiling issues can mimic cam sensor problems. A good workshop can test live data and get it sorted quickly, usually inside an hour.

How many camshaft sensors does a 2019 Honda Accord have?
Most Aussie/NZ 2019 Accord petrol models (1.5T and 2.0T) are DOHC and typically have two camshaft position sensors—one on the intake cam and one on the exhaust cam. The hybrid variant also uses a camshaft position sensor for engine synchronisation, though the layout differs due to the e-CVT hybrid system.

Can it be driven with a bad camshaft sensor?
Often it will still run, but it may crank longer, stumble, or drop into limp mode. Prolonged driving can risk misfires that aren’t great for the catalytic converter. Best bet is to diagnose and fix promptly so fuel economy and performance don’t suffer.

Is a relearn needed after replacement?
Generally, the ECU will sort itself after a clear of codes and a short drive. If the battery’s been disconnected, performing an idle learn is a good idea. No special cam sensor “programming” is typically required on the 2019 Accord—just ensure correct installation and no wiring faults.
