P0441 indicates incorrect purge flow detected for the evaporative emissions system. P0446 indicates a vent control malfunction for the evaporative emissions system. When they both come on together, it can mean there is an evaporative emissions system leak somewhere that needs to be found, or can mean something malfunctioning with the vapor pressure sensor. Hands on diagnostic testing is required.
