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?
have the same problem?
