2010 Honda Odyssey Camshaft Sensor — Purpose, Service Tips, and Replacement Advice

Based on Honda’s factory service information for the 2005–2010 Odyssey (J35 V6), the Honda Electronic Parts Catalogue, and the model’s OBD‑II diagnostic coverage (DTCs such as P0341 and P0344 for camshaft position circuit faults), the 2010 Honda Odyssey is fitted with a camshaft position sensor (CMP) and relies on it for normal operation. So yes, this part is relevant and used on the 2010 Odyssey.

The camshaft sensor tells the engine control module where the camshaft sits relative to the crankshaft. That timing info lets the Odyssey’s PGM‑FI system fire injectors sequentially, sharpen ignition timing, and manage systems like i‑VTEC/VTC and cylinder deactivation on V6 variants. When the CMP signal is clean, the van starts quickly, idles smoothly, and pulls strongly while keeping fuel use in check. A failing sensor can cause long cranks, rough running, random stalling, misfires, poor economy, or a no‑start with the check engine light on.

The CMP sensor isn’t a routine service item, but it benefits from a quick look during scheduled servicing. Check the plug and wiring for heat damage, oil intrusion, or corrosion, and make sure the O‑ring isn’t weeping. Because correct cam timing is essential for the sensor’s job, sticking to the timing belt service interval (around 160,000 kilometres/7–8 years, per Honda guidance for the J35) is smart maintenance. Healthy battery voltage and solid engine earths also favour clean CMP signals.

If replacement is needed, use a quality OEM or OE‑equivalent part. Under the bonnet, the sensor is mounted to a cylinder head near the camshaft, access varies by bank and trim. Typical steps are:

• Let the engine cool, disconnect the negative battery terminal.
• Unplug the connector, remove the small retaining bolt, and twist the sensor free.
• Lightly oil the new O‑ring, install the sensor, and tighten the bolt to the specification in the Honda service manual.
• Reconnect, clear fault codes, and perform an idle learn if required.

Most 2010 Odysseys won’t need programming after a CMP swap, the ECU will relearn on its own once codes are cleared. If a code returns, recheck the connector, harness routing, and mechanical cam/crank timing. For DIYers, a 10 mm socket, a torque wrench, and a decent scan tool make the job tidier. For everyone else, a qualified technician can sort it quickly.

Popular questions about the 2010 Honda Odyssey camshaft sensor

Where is the camshaft sensor located on a 2010 Odyssey?
It’s mounted to a cylinder head near the end of the camshaft, typically secured by a single small bolt with an O‑ring seal. On the V6, access can differ by bank and trim, so checking the service manual diagram or a parts image helps pinpoint it under the bonnet.

What are common signs the camshaft sensor is failing?
Expect extended cranking, rough idle, intermittent stalling, misfires, sluggish performance, or the check engine light. Fault codes like P0341 or P0344 often appear. Because these symptoms overlap with timing belt or crank sensor issues, a proper scan and wiring check saves guesswork.

Do I need to program the new camshaft sensor?
Generally, no. After fitting the sensor, clear codes and let the ECU relearn during a normal drive cycle. If idle quality is off, run the Honda idle learn procedure. Persistent faults suggest wiring, connector, or mechanical timing concerns rather than programming.
