PO 446 the scanner says evap system control fault.
What is this and can anyone explain what needs to be done to correct it?

Make sure your gas cap is screwed on tight. This is most likely the cause of the code. Evap is not likely an issue in this vehicle unless you had a supercharger or evap port clog. Did you get gas and overflow the tank? Also a possibility. In any case evap can only be tested from an OBD scanner and pass when it is COLD.
