P0456 is Evap Leak Monitor, Small. This translates into that you have a small leak in the fuel system, either a gas cap that didn't quite seal when you put it on to a very small crack in one of the vapor recovery lines. The leak would not be in the pressure line from the tank to the fuel rail/injectors.
