Turned on vehicle in the morning to go to work. Engine check soon light came on and wouldn't go off. Dropped vehicle off at dealership. Say it is the purge volume control valve but they cannot get the computer to reset with their computer in the service department. Stated they may need to keep the vehicle more than one day.
