Parts for your 2016 Honda Odyssey-Camshaft sensor

2016 Honda Odyssey camshaft sensor — what it does and when to replace it

Referencing technical sources including the Honda Service Manual for the 2016 Odyssey (Engine/Control, Fuel & Emissions section for CMP Sensor A/B), Honda’s genuine parts catalogue listings for the J35 V6, and the Honda OBD-II DTC set (codes P0341–P0343 and P0365–P0367), it’s clear the 2016 Honda Odyssey is fitted with camshaft position sensors. In fact, it uses two: Camshaft Position Sensor A (Bank 1, rear cylinder head) and Camshaft Position Sensor B (Bank 2, front cylinder head). So yes — a camshaft sensor is absolutely relevant on this model.

This sensor lets the engine control module know exactly where the cams are, so it can sync fuel injection and spark, manage i‑VTEC/VTC timing, and operate cylinder deactivation (VCM) smoothly. If the signal goes missing or dodgy, the Odyssey can be hard to start, run rough, feel flat on power, burn more fuel, or bring up the check engine light with the codes noted above.

It’s not a scheduled service item, but it does benefit from a bit of care. Clean oil matters because the cam timing system relies on good oil flow, sticking to the correct 0W‑20 and timely changes helps the sensor read stable cam timing. During servicing, it’s smart to inspect the sensor connectors on both heads for oil wicking, brittle wiring, or loose clips. Small oil leaks around the sensor O-rings can be picked up early and sorted before they cause faults.

When replacement is needed (usually after confirmed fault codes and testing), most home spanner‑spinners can manage it with basic hand tools:

• Disconnect the battery negative and remove the engine cover.
• Unplug the CMP sensor (rear head for Sensor A, front head for Sensor B), remove the retaining bolt, and twist the sensor out.
• Lightly oil a new O‑ring, install the new sensor, and tighten the bolt to the Honda‑specified torque (check current service data).
• Clear codes and, if required, carry out an idle learn procedure.

Quality matters here — a genuine Honda or reputable aftermarket sensor helps avoid intermittent faults. If the vehicle’s showing long cranks, random stalling, or a sudden drop in fuel economy, a scan test and live‑data check of the cam/crank synchronisation is the right first move before throwing parts at it.

How many camshaft sensors does a 2016 Honda Odyssey have?

It has two camshaft position sensors — one on each cylinder head. Honda labels them Sensor A (Bank 1, rear head) and Sensor B (Bank 2, front head). Both are monitored by the ECU and can set distinct fault codes if there’s an issue.

Where are the camshaft sensors located on the 2016 Odyssey?

They’re mounted in the ends of the cylinder heads: Sensor A at the rear bank (closest to the firewall) and Sensor B at the front bank (closest to the radiator). Access usually involves popping off the engine cover and reaching the respective head.

Is it safe to drive with a bad camshaft sensor?

It may still run, but it can be hard to start, lack power, and use more fuel. Prolonged driving risks poor performance and could trigger further faults. Best bet: scan it, confirm the code, check wiring and the O‑ring area for leaks, then replace the sensor if tests point that way.
