What is your question?
I was driving at 75mph when my emission warning light was on. Then I pulled over and turned off the engine. I turned on the engine after 5 seconds. The warning light was gone. It didn't come back again. Once I arrived at one gas station, I pulled out my car's manual and started looking at it. One thing I read as a cause for emission warning light display is loose gas tank cap. I checked the gas tank cap. Interestingly, It was not tight. Immediately, I remembered gassing up my dependable beast expedition. I genuinely love my vehicle. Now my question is: Could that be the only reason? Indeed, I will take my beast for its computer diagnosis or scanning. Thanks
What makes this problem better or worse?
No other problem.
How long has your 2007 Ford Expedition had this problem?
Only once for about 5 seconds.

You were going to fast! ECM may or may not have stored the code.No use to take it in unless you want to fly by Autozone in you BEAST and see if they can pull a code,it's free. If they pull a code,ask them to print it out for you and post the code here,printing code is free also! If no code(s) drive the BEAST on!
Thank you so much. I was driving at such speed because I was on a highway driving from one city to another city in my state; and where I was required to operate the vehicle at such a speed limit(75mph) by law. You know what I mean. Anyways, what is an ECM? Is it something that detects the emission warning light related problem? Thank you so much again.
Yes>>>ECM=Computer/Brain....
Thank you!
