A code P0455 indicates a large leak in the evaporative emissions control system, not necessarily a bad catalytic converter. While a malfunctioning catalytic converter can cause various issues, this specific code is more likely related to problems with the gas cap, fuel lines, or other components of the emissions system. It's important to diagnose and address the source of the P0455 code before concluding that the catalytic converter is At Fault.
No, that code is for the evaporative emissions control system in the fuel tank. It has nothing to do with the catalytic converter.
