Parts for your 2020 Honda Odyssey-Camshaft sensor

2020 Honda Odyssey Camshaft Sensor

Yes, the 2020 Honda Odyssey is fitted with camshaft position sensors. Honda’s own service information for the 2018–2020 Odyssey (J35Y6 3.5‑litre V6) details Camshaft Position (CMP) sensor diagnostics and replacement, and lists related DTCs such as P0341 and P0365. Honda parts catalogues for this model also show CMP sensors as serviceable components, typically one per cylinder bank. That makes the camshaft sensor directly relevant to this vehicle’s engine management and servicing.

The camshaft sensor’s job is to tell the engine control unit exactly where each camshaft is in its rotation, so fuelling, spark, and variable valve timing can be timed spot‑on. Paired with the crankshaft sensor, it lets the Odyssey start cleanly, idle smoothly, and optimise power and economy. On the J35Y6, accurate cam data is crucial for VTC/VTEC operation, cylinder activation, and emissions control.

It isn’t a routine “replace-by-interval” item, but it deserves attention whenever drivability issues crop up or when carrying out bigger jobs under the bonnet, like timing belt and water pump service. Keeping engine oil fresh helps the valve‑timing hardware behave, which in turn keeps cam signals consistent. It’s also worth making sure the sensor connectors are clean, the harness isn’t chafed, and there’s no oil intrusion at the plug.

• Common signs of a failing CMP sensor: longer cranking or no start, rough idle, flat spots on acceleration, poor fuel economy, and the check‑engine light (often with codes P0340/P0341/P0365/P0366).
• Basic service tips: verify fault codes first, inspect wiring and reluctor areas, and only then replace the sensor if it fails testing. Genuine or quality OEM‑equivalent parts are recommended.

Replacement is straightforward for a trained tech: disconnect the battery negative, locate the CMP sensor on the cylinder head (one per bank), unplug the connector, remove the retaining bolt, swap the sensor and O‑ring, then refit and clear codes. Afterward, a short drive cycle confirms the repair. Labour time is typically well under an hour per sensor, making this a sensible fix before chasing more complex causes.

For owners aiming to keep an Odyssey running sweet across Aussie and Kiwi conditions, treating the camshaft sensor as a diagnostic priority—not a guess—saves time, coin, and unnecessary parts swapping.

Popular questions about the 2020 Honda Odyssey camshaft sensor

Where is the camshaft sensor located on a 2020 Honda Odyssey?

On the J35Y6 V6, a camshaft position sensor is mounted on each cylinder bank at the cylinder head. Access is from the top of the engine bay, near the rocker/valve cover area. The exact orientation can vary slightly with market trim and intake ducting, but both sensors are reachable without major disassembly.

A workshop manual or parts diagram helps confirm Bank 1 versus Bank 2, which is handy when diagnosing codes that call out a specific bank.

Does the camshaft sensor need regular replacement?

No routine interval is specified by Honda. The sensor is replaced when diagnostic testing confirms a fault or when there’s physical damage or oil contamination. During major services—like timing belt and water pump replacement—it’s smart to inspect the sensors and connectors and clean any grime so signal quality stays reliable.

What symptoms suggest the camshaft sensor is failing?

Typical symptoms include extended cranking, rough idle, hesitation, reduced power, higher fuel use, and an illuminated check‑engine light. Scan tools often show DTCs such as P0341 or P0365. Because wiring faults can mimic a bad sensor, proper testing—visual checks, connector pin fit, and live data—should be done before parts are replaced.
