You can suspect a bad catalytic converter in your Honda or Acura, such as the 2009 Honda Odyssey or 2016 Acura MDX, if you notice symptoms like reduced engine performance, poor fuel efficiency, or a sulfur-like rotten egg smell from the exhaust. The check engine light may also illuminate, and a diagnostic trouble code ( P0420 and/or P0430 ) related to the catalytic converter can be retrieved using an OBD-II scanner. It's advisable to have a professional mechanic confirm the issue for accurate diagnosis and repair, especially for models with the 3.5L, 3.7L engines, Bank 2, Front Manifold, and California/NY/ME/CO legal catalytic converters.
