Thanks, blwnsmoke.....sounds like a real good idea. I haven't owned a Ford in many years, hope that engine lights are not a problem of the breed,
The PCM's logic is a bit more complex than that in order to reset the MIL. Just drive it a few days normally while keeping the fuel level between 1/4 and 3/4 of a tank (the self-test won't run if the fuel level is outside those limits). Generally, it takes 3 consecutive drive cycles in which the self-test runs to turn off the MIL. A drive cycle must include a shut-down period that allows the engine to cool down by a specified amount so simply stopping and restarting doesn't count. Unless you have an immediate requirement for an emissions test, just sit back and take your time.

jjtxaz24.....as I was the last one here with the same issue, I will explain what I did. I continued to have the light on after changing the purge valve and the light was stubbornly not going off. I followed all the suggestions about driving cycles, not overfilling the tank, etc.....with no success. As I was about to give up and resign myself to taking it in, I stopped back at the parts store where I had purchased the valve and the manager was kind enough to come back outside and reconnect his diagnostic tool. These tools have an option (which they are really not supposed to use) which allows them to turn off the light. It has been months, and many miles, and multiple fillups and I passed the EPA tests and have not seen the light again. Hope this helps you.
Hopefully all he did was just clear the code and nothing else.
Welcome to the Forum.
Good luck and please keep us in the loop if you get it fixed. Thanks.

peterk9.....I have no reason to believe he did anything but clear that particular code. I have had no other issues of any kind since. I certainly bow to your experience with Ford as I really have none...but I have worked on and around cars my whole life and sometimes I believe we are led to overthink stuff by manufacturers and dealers. It sometimes reminds me of computers such as the one I am sitting in front of right now..... the wife and I have successfully repaired them on numerous occasions, where gloom and doom was predicted. I could be all wrong about this code, but if it was or could be caused by a dumb little thing like overfilling the gas tank; which I think it was in my case, I believe the simplest and least expensive attempts are often worth a try.
As for overfilling the tank. I always give it one more click after the initial auto shut-off and have never had an issue. On older cars I had I used to slowly squeeze the trigger until I could see that gasoline in the tube.
I don't do that with these vehicles.
