What makes you think it's the fuel cap?
The code is alerting you to a problem-that can leave you stranded.
Get it diagnosed.
I do not know about Ford gas caps but I can tell you from more than one experience that If you do not "click" a Chevy gas cap 5 plus times the light will come on. tI was made aware of this when I called because when I called the service department on a Chevy check engine lite, new car third day I had it, the service advisor asked me if had bought gas recently and when I told I had he told me to go out take gas cap off put it back on count 20 clicks and if the light was still on in a week call them back. It solved the problem.
