You are close in your understanding of what the P0430 code means. In reality it means the bank 2 (front) catalytic converter isn't cleaning up the exhaust as much as the ECM wants it to. The converter isn't getting any more (or less) fouled now than what it was. In the majority of cases I have observed the converter is flowing just fine and isn ...Code P0430 Catalyst system efficiency below threshold bank 2.
