P420 with Ev not resetting

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! I'm not quite sure I understand the question. A P0420 code usually points to the catalytic converter's efficiency being below threshold, but if your OBD shows the cat converter is passing, it's likely something else in the emissions system causing the issue. The "Ev" light not resetting could mean an issue with the evaporative emissions system. Check for any leaks or faults in the EVAP system components, like the purge valve or vent valve, or if the EVAP hasn't been set after clearing the codes. The car will have to perform a drive cycle of 50-100 miles before it sets readiness.
