2000 Chevrolet Express P0442 Fault AfterReplacing Catalytic Converter
I'm experiencing fault code P0442 on my 2000 Chevrolet Express. I recently replaced the catalytic converter, but the code persists. What does P0442 mean, and could this be related to the replacement? Is there a specific check needed after replacing the cat converter?
P0442 indicates a small evaporative system leak. After replacing the catalytic converter, ensure all EVAP lines are properly connected and sealed. A smoke test is recommended to verify integrity of the evaporation system.
