The EVAP system pulls gasoline fumes into the engine to be burned with the air to fuel mixture instead of being released into the atmosphere. Code P0455 means the computer has detected a large leak in the EVAP system. Possibly a hose is broken or disconnected. A missing gas cap can set that code as well. Hope that helps! Jim
