The Bank 2 catalytic converter on a Honda Odyssey is located on the passenger side of the engine, along the Bank 2 exhaust path between the cylinder-bank manifold and the main exhaust pipe. In most model years, this unit sits under the vehicle toward the middle, integrated into the exhaust run that serves cylinders 2, 4, and 6.
Honda Odyssey models powered by the 3.5-liter V6 (the J35 family) use two exhaust banks. Bank 2 corresponds to the side that carries cylinders 2, 4, and 6, and its catalytic converter is the downstream emissions control unit on that bank. While the general arrangement is consistent across generations, exact mounting and routing can vary slightly by year and trim level, so verification by inspection is wise if you’re planning service work.
Understanding Bank 2 in the Odyssey
Bank 2 refers to the exhaust side that includes cylinders 2, 4, and 6. The catalytic converter on this bank is positioned along the Bank 2 exhaust manifold run and is located downstream in the exhaust stream—between the manifold and the main exhaust piping that continues toward the rear of the vehicle. Most Odysseys display an additional oxygen sensor near the converter to monitor its performance, with another sensor located before the converter in the exhaust stream as part of the overall emissions system.
Where to look on the vehicle
Use these observations to visually identify the Bank 2 catalytic converter on a Honda Odyssey:
- Follow the exhaust path from the Bank 2 manifold (the side of the engine that serves cylinders 2, 4, and 6) toward the center of the vehicle. The catalytic converter is the larger metal canister embedded in that exhaust pipe.
- In most Odysseys, Bank 2’s converter sits along the passenger-side exhaust route, often under the vehicle and near the engine cradle or subframe, sometimes with a heat shield around it.
- Look for an oxygen sensor on the pipe after the converter (the post-cat sensor) and, in some cases, a sensor before the converter (pre-cat) on the same exhaust bank.
When in doubt, tracing the exhaust from the passenger-side manifold toward the rear of the vehicle is the most reliable way to confirm the Bank 2 catalytic converter’s location. The unit is the canister in that run, typically with a heat shield and mounting hardware that secures it to the undercarriage.
Model-year variations
While the general rule holds across most Odyssey generations, occasional differences can occur in mounting brackets, shield sizing, or routing due to redesigns or trims. If you’re working on a specific year, consulting a service manual or a vehicle-specific diagram can provide exact coordinates and mounting details.
Safety and maintenance notes
Working around the exhaust system carries safety risks. Ensure the vehicle is fully cooled, use proper jack stands and wheel chocks, and wear eye protection. Be aware that altering or removing emission-control devices can be illegal in many jurisdictions and may affect vehicle inspections or warranty coverage.
- Always disconnect the battery and work from a secure lift or jack stands when accessing undercar components.
- Do not work on a hot exhaust system to avoid burns.
- Follow local regulations regarding emission-control devices and repairs.
Consult a qualified mechanic if you’re unsure about locating or servicing the Bank 2 catalytic converter, especially since improper handling can affect emissions performance and vehicle compliance.
Summary
For a Honda Odyssey, Bank 2 is the exhaust bank containing cylinders 2, 4, and 6. The Bank 2 catalytic converter is the downstream converter on that bank, typically located on the passenger side of the engine, along the exhaust run that moves toward the middle/rear of the vehicle. If you need to access it, verify the exact year model and consult reference diagrams, and always prioritize safety and legal considerations when working on the exhaust system.
