EVAP is evaporative emissions which include the raw fuel vapors from the tank. They are known as hydrocarbons. The evap system contains these vapors and disposes of them through the burning process in the engine. You have valves and solenoids controlled by the computer to purge them from the system. Some of the parts that may cause this test to fail are the vapor lines to and from the tank, the fuel cap (loose or leaking), the carbon canister, and the purge valve or solenoid. It is a somewhat difficult system to test because it is under very low pressure. With all the components in the system, it is hard to say which is at fault. There is a pressure tester provided by Rotunda (Ford service tool) that is made to diagnose this particular problem. You local dealer should have one. About all you can do yourself is visually check the lines and the fuel cap for obvious problems. The MIL light may be on for this reason also. I hope this helps.
