The Bank 2 catalytic converter on a 2010 Honda Odyssey is located on the passenger side of the engine, along the exhaust manifold, before the downpipe to the center of the exhaust. It serves the opposite bank from Bank 1.
Understanding Bank 2 on this model
In a V6 engine mounted transversely, Bank 1 is the bank that contains cylinder 1, and Bank 2 is the opposite bank. For the 2010 Odyssey, Bank 1 is typically on the driver's side, while Bank 2 sits on the passenger side. Each bank has its own catalytic converter and pair of oxygen sensors, positioned along the respective exhaust paths to monitor emissions and catalyst efficiency.
Steps to locate the Bank 2 catalytic converter
Use this guide to find the physical unit under the vehicle and along the engine side. Before you begin, ensure the vehicle is safely raised and supported, and allow the exhaust to cool.
- Raise and support the Odyssey securely; apply wheel chocks and use jack stands as needed.
- From underneath the vehicle, follow the exhaust path on the passenger side. Trace the pipe that exits the right-hand side of the engine toward the center of the vehicle.
- Look for a metal canister with a heat shield mounted along that pipe—that is the catalytic converter for Bank 2.
- Identify the oxygen sensors: you should find an upstream sensor near the manifold and a downstream sensor after the converter on the same bank.
- Confirm connector routing and pipe orientation by tracing the pipe forward toward the engine bay to ensure it connects to the passenger-side exhaust manifold.
With the converter located, you can plan service tasks such as inspection, replacement, or sensor work. If you suspect a bank 2 oxygen sensor or converter fault, the OBD codes commonly associated with this bank in Honda vehicles include P0430 (Bank 2 Catalyst System Efficiency Below Threshold), though codes can vary by year and scanner.
Safety and maintenance considerations
Always work with the vehicle cool, wear gloves and eye protection, and use proper jack stands. If you’re not comfortable performing exhaust work, consult a qualified technician. Emissions systems can be damaged if disturbed improperly, and incorrect installations can affect vehicle performance and emissions readings.
Summary
For a 2010 Honda Odyssey, Bank 2 catalytic converter is positioned on the passenger side of the engine, along the exhaust manifold, ahead of the downpipe toward the center of the exhaust system. It is part of the dual-bank catalytic setup and is accompanied by upstream and downstream oxygen sensors. Correct identification helps with diagnostics, inspection, and maintenance.
