The fuel system on newer vehicles is pressurized, if the computer detects that the fuel system is "leaking" pressure it throws a code. The most common problem is that the gasket on the fuel cap is either broken(cracked or missing pieces) or dry. If it is broken replace the cap. If the seal looks ok rub a thin layer of Vasoline on it and be sure to properly tighten it, on most Fords they can only be turned a certain amount.
