take the car to dealership and get them to cancel the fault memory of the engine control unit. Then if the warning light comes back on you will need a full diagnosis check to establish what is causing thefault.

Take your car to an autozone they can scan the codes for you. Your on-board diagnostic is telling you something is wrong. They cannot tell you exactly what is wrong but they can point you in the right direction. Can't beat it for the price of free. If you want to know exactly what is wrong you will need to take it to a licensed ford mechanic or dealer.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
