2014 Honda Odyssey Camshaft Sensor — Purpose, Service Tips, and FAQs

Technical sources confirm a camshaft sensor is fitted and relevant on the 2014 Honda Odyssey. The Honda 2011–2017 Odyssey Service Manual (Engine Electrical, Camshaft Position (CMP) Sensor A/B — System Description and Replacement), together with the Honda parts catalogue listing Sensor Assy., Cam Position (commonly 37510-R70-A11, superseding -A01/-A02), show the J35 3.5‑litre V6 uses camshaft position sensors. These sensors are integral to sequential fuel injection, ignition timing, and VTEC/VCM control as outlined in Honda’s system descriptions and general OBD‑II strategies.

On the 2014 Odyssey, the camshaft sensor(s) keep the ECU in the loop about exactly where the cams are, so fuel and spark happen right on cue. With the J35 V6 running VTEC and cylinder deactivation (VCM), that timing data is non‑negotiable for smooth drivability and good fuel economy. This model typically has two CMP sensors, one per cylinder bank, mounted at the ends of the cylinder heads near the timing covers.

There’s no scheduled replacement interval for the CMP sensors — they’re a “fit and forget” item unless faults crop up. During regular servicing it’s smart to give the connectors a quick look, check for oil seepage around the sensor O‑ring, and make sure the wiring isn’t chafed. If the Check Engine Light pops up with codes like P0340, P0341, P0344 or related, or there’s hard starting, rough idle, misfires, sluggish performance or poor fuel use, a failing CMP sensor or its circuit could be the culprit.

Replacement is straightforward for a DIYer with basic tools, but many owners will prefer a technician. Typical steps include disconnecting the battery, removing the engine cover, unplugging the sensor connector, and undoing the retaining bolt. Lightly oil the new O‑ring, seat the sensor squarely, and torque the bolt to the Honda spec (commonly around 9.8 N·m / 7.2 lb‑ft — verify against current service information). Clear codes and confirm live data and timing advance look healthy on a scan tool.

• Use genuine or OE‑quality sensors (e.g., 37510‑R70‑A11) to avoid intermittent faults.
• If oil is found in the connector, replace the sensor and clean the plug — oil wicking can cause repeat issues.
• Always inspect related grounds and the crank sensor signal if CMP codes persist.

Popular questions about 2014 Honda Odyssey camshaft sensors

How many camshaft sensors are on a 2014 Odyssey and where are they?
This V6 typically uses two CMP sensors, one on each cylinder bank. One sits toward the radiator side (front bank), and the other is near the firewall (rear bank), each at the end of the cylinder head by the timing cover under the engine cover.

Do camshaft sensors need routine replacement?
No scheduled interval. They’re replaced on condition. During servicing, check the connectors, wiring, and for any oil leaks at the sensor O‑ring. Replace the O‑ring when fitting a new sensor and verify torque to spec.

What are the common signs a CMP sensor is failing?
Check Engine Light with codes like P0340–P0345, hard starting, rough idle, misfires, hesitant acceleration, poor fuel economy, or the transmission feeling a bit confused on shifts. A scan tool showing erratic cam signal confirms the diagnosis.
