Where is the bank 1 sensor 1 located on a Honda odyssey?

On a Honda Odyssey, the bank 1 sensor 1, which is the upstream oxygen sensor, is located on the exhaust manifold or just before the catalytic converter on the engine side. This sensor monitors the oxygen levels in the exhaust gases to help manage the air-fuel mixture for optimal engine performance. Accessing it may require raising the vehicle and working from underneath, depending on the specific model year.
