Parts for your 2013 Honda Odyssey-Camshaft sensor

2013 Honda Odyssey camshaft sensor — what it does and when to replace it

Technical sources confirm the 2013 Honda Odyssey is fitted with camshaft position sensors (CMP). The Honda Odyssey 2011–2017 Service Manual (Engine Control – Camshaft Position Sensor) outlines testing and replacement. Honda’s electronic parts catalogue lists a CMP sensor for this model (commonly referenced as p/n 37510‑R70‑A01), and standard diagnostics for the J35 V6 include CMP-related DTCs such as P0341 and P0346 (Bank 1/2). That makes the camshaft sensor absolutely relevant to the 2013 Odyssey.

On this V6, the camshaft sensor tells the ECM/PCM exactly where each cam is relative to the crank. That timing feedback lets the Odyssey run sequential fuel injection and accurate spark timing, manage VTEC and Variable Cylinder Management, and keep cold starts clean and smooth. If that signal goes missing or drifts, the engine management will fall back to a safe strategy that feels flat and thirsty.

• Typical warning signs include a check engine light, hard starting, rough idle, reduced power, misfire behaviour, higher fuel use, and stored codes like P0341/P0346.
• There’s no routine replacement interval, but good oil quality matters — sludge and varnish can upset signal quality or the sensor’s O‑ring seal.

The 2013 Odyssey generally uses two camshaft sensors, one per cylinder bank. They’re mounted at the ends of the cylinder heads (front and rear banks). Quality matters here: use genuine or reputable aftermarket parts and replace the O‑ring. Always inspect the wiring looms and connectors for oil ingress or rub-through before condemning a sensor.

1. Switch the ignition off and disconnect the negative battery terminal.
2. Remove the engine cover and any intake ducting needed for access under the bonnet.
3. Unplug the sensor connector and check pins for corrosion or oil.
4. Remove the retaining bolt and gently withdraw the sensor, catch any drips.
5. Lightly oil the new O‑ring, seat the new sensor squarely, and tighten the bolt snugly (follow workshop specs).
6. Reconnect the plug, refit covers, reconnect the battery, clear codes, and road test.

Expect modest labour — often under an hour per side — unless access is tight. If faults return, a technician should verify crank–cam correlation, loom integrity, and ECM updates referenced in workshop information. Done properly, a new sensor restores crisp starts, smooth idle, and proper fuel economy for many more kilometres.

Popular questions

How many camshaft sensors are on a 2013 Honda Odyssey?
The V6 typically has two camshaft position sensors, one for each bank (Bank 1 at the rear/firewall side, Bank 2 at the front/radiator side). The ECM uses both signals to keep fuel and spark events in sync with cam timing features like VTEC and cylinder deactivation.

Is it safe to keep driving with a faulty camshaft sensor?
Short local trips may still be possible, but drivability will suffer and fuel use can spike. Prolonged driving with misfires or poor timing can stress the catalytic converters. It’s best to organise diagnosis and repair sooner rather than later.

Does the Odyssey need a relearn after replacing the camshaft sensor?
In most cases the ECM will adapt on its own after codes are cleared and a proper drive cycle is completed. Some scan tools offer correlation checks, if idle is unstable or a code returns, a technician can run guided procedures from workshop information.
