I recently passed state emissions testing. Exactly four days later, my SES light came on revealing code: P0430 Catalyst System Efficiency below threshold Bank 2. Now I am told I need a new catalytic converter. How is this possible? Do catalytic converters just go bad one day? How can it pass one day and be dead the next?

Do you
have the same problem?

Possibly the catalytic converter, exhaust leak and oxygen sensor problem
