To determine if the catalytic converter is bad or if it's just the bank 2 sensor, you can start by checking for warning lights on the dashboard, such as the check engine light. Use an OBD-II scanner to read any error codes; codes related to the catalytic converter (like P0420) indicate potential issues with it, while codes specific to the sensor (like P0138 for bank 2) suggest a sensor problem. Additionally, you can inspect the exhaust system for unusual noises or smells, and perform a visual check for physical damage or clogs in the catalytic converter. If the converter is excessively hot or glowing after driving, it may be failing.
