2001 Honda Odyssey crank-angle sensor: purpose, care and replacement

Based on the Honda Odyssey 1999–2004 Factory Service Manual (Helm Inc.) and the Honda Electronic Parts Catalogue for the J35A1 engine, the 2001 Odyssey is fitted with a crankshaft position sensor—commonly called a crank-angle sensor. The manual details diagnostic codes such as P0335 for the CKP circuit, and the parts catalogue lists the CKP sensor (e.g., Honda p/n 37500‑P8E‑A11) for this model. Industry application data from major sensor manufacturers also lists a CKP for the 2001 Odyssey. So yes, this vehicle uses a crank-angle sensor.

On the 2001 Odyssey, the crank-angle sensor reads a toothed wheel on the crankshaft to report exact crank position and engine speed to the ECU. That timing data lets the ECU fire the coils and injectors at the right moments, keeping the V6 smooth, efficient and easy to start. Without a clean signal, fuelling and spark go off, and the van can be a hard starter, stall at idle, or log fault codes.

• Common symptoms of a dodgy CKP: intermittent no‑start when hot, sudden stalling, rough running, weak acceleration, and OBD‑II codes P0335–P0339.
• Typical location: mounted low at the front of the engine near the crank pulley/oil pump area, behind the right wheel arch liner.

There’s no routine servicing for the sensor itself, but owners benefit from periodic checks of the wiring loom and connector—heat and road grime can make connectors brittle or dirty. During big-ticket jobs like timing belt and water pump service (commonly around 160,000 km or 7 years), it’s smart preventative maintenance to inspect or proactively replace the CKP due to age and access.

1. Disconnect battery and safely raise the vehicle. Remove the right-front wheel and splash shield for access.
2. Visually inspect the harness for chafing, oil contamination, or loose pins before condemning the sensor.
3. If replacing, unplug the connector, remove the retaining bolt, and gently extract the sensor and O‑ring. Lightly oil a new O‑ring and seat the new sensor squarely.
4. Clear fault codes and verify stable RPM signal on scan data during a road test.

Quality OEM‑equivalent sensors are preferred to avoid false triggers or start issues. Given the tight working space, many owners have a technician handle it, labour is modest when combined with front‑end service. Keeping this little sensor healthy pays off with reliable cold starts, smooth idle, and better fuel economy on school runs and long Kiwi and Aussie road trips alike.

Popular questions

Where is the crank-angle sensor on a 2001 Honda Odyssey?
It sits low on the front of the engine, near the crank pulley on the oil pump housing. Access is typically from the right wheel well after removing the splash shield.

Do these sensors fail often, and should they be done with the timing belt?
They’re generally reliable but can fail with age and heat. Many workshops recommend inspecting or replacing the CKP during timing belt/water pump service because access overlaps and the van is already apart.

What codes point to a bad crank-angle sensor on this model?
Common OBD‑II codes include P0335 to P0339 relating to crankshaft position signals. Always check wiring and connectors first, as harness issues can mimic sensor faults.
