2001 Honda Odyssey camshaft sensor: purpose, fitment and servicing
Technical references including the Honda Odyssey 1999–2001 Service Manual (Helm), Honda’s electronic parts catalogue, and standard OBD‑II fault listings (e.g., P0341/P0344 for Camshaft Position Sensor A) confirm that the 2001 Honda Odyssey (J35A1 V6) is fitted with a camshaft position sensor. Honda documentation may also refer to it as the TDC/CMP sensor, it’s mounted on the cylinder head and read by the PCM to keep engine timing spot‑on.
On this Odyssey, the camshaft sensor’s job is to tell the powertrain control module exactly where the camshaft sits in its rotation. With that info, the PCM synchronises sequential fuel injection, coil firing and valve timing strategies, and it can accurately detect misfires. It’s particularly important for clean starts, smooth idle, decent fuel economy and keeping emissions within spec.
When the sensor starts playing up, the van can be a pig to start, idle roughly, hesitate under load or stall at junctions. The Check Engine light usually joins the party, commonly logging codes like P0341 (range/performance) or P0344 (intermittent). Because the J35 uses a timing belt and the sensor lives in a hot, oily environment, heat cycling, oil contamination around the connector and aged O‑rings are frequent culprits.
While the cam sensor isn’t a scheduled service item, it’s smart to give it a once‑over whenever the rocker cover is off or the timing belt service is being done. Look for hardened or cracked wiring, oil wicking into the plug, or a flattened O‑ring. If replacement is needed, stick with quality OE‑equivalent parts to avoid nuisance faults.
- Disconnect the battery and let the engine cool.
- Locate the sensor on the cylinder head (under the bonnet, timing belt end).
- Unplug the connector, remove the retaining bolt(s) and lift the sensor out.
- Lightly oil and fit a new O‑ring, seat the new sensor squarely.
- Reinstall bolt(s) and tighten to the service‑manual spec, reconnect the plug.
- Clear codes, start the engine, and check live data, perform an idle learn if required.
A careful install, correct harness routing, and a fresh O‑ring usually restores crisp starts and smooth running. If codes return immediately, check cam timing, power/earth at the connector and wiring continuity before condemning the new sensor.
Popular questions about the 2001 Honda Odyssey camshaft sensor
Where is the camshaft sensor on a 2001 Odyssey?
It’s mounted on the cylinder head at the timing belt end of the engine, under the bonnet. Access varies slightly by market trim and covers, but it’s typically near the upper timing cover area with a small multi‑pin connector. A torch and a 10 mm socket make life easier.
What codes point to a bad camshaft sensor on this model?
Common OBD‑II codes include P0341 (Camshaft Position Sensor A – Range/Performance) and P0344 (Intermittent). Extended cranking, rough idle and stalling often accompany these. Always verify power, ground and signal integrity before replacing the sensor.
Will a failing camshaft sensor damage the engine?
It’s unlikely to cause direct mechanical damage, but it can lead to poor running, increased fuel use and potential catalyst stress from misfires. Best to diagnose and sort it promptly to keep the Odyssey driving sweet and emissions‑compliant.
