Check Engine Light on due to fuel cap open

Give it a few more days, I've read that will do it. I don't think it impairs vehicle operation, other than the light bugging you. Disconnecting the 12 volt battery *might* clear it. If you're going sometime soon for tire rotate they might clear it for free.

 

you need a certain amount of ignition on's without triggering any failure messages/
so if you go like ten times back & forth in ready mode & totally off, it should be gone//

 

This. Or, ignore it as mentioned above, till it goes away.

right.
for normal you don't even have to start the engine; just get it in ready mode for a few seconds & then turn it off again.

The problem will go away by itself. Every OEM is a little different, but you have to cycle the vehicle several times to clear the evaporation emissions containment system fault.
If you grow impatient some places like Pep-Boys or Auto Zone will clear the codes for you.

There's a very slight chance that you'll mask a new problem during the 10-20 drive cycles that it will take to clear the problem, but I wouldn't worry about that on a 2014.

 

Pick up an el cheapo code reader off of eBay or something to clear codes. This won't be the last time.

 

Just so we're clear on this:
Take any modern car; remove the gas cap; drive around for a bit, and the Check Engine light's going to go on.
Take said modern car; put the gas cap back on; take $RANDOM number of trips; and the Check Engine light will go off.

Eventually. When the software developers who put the check in there decide that it's time.

You can speed up the process with $$$ and Trouble, or just Breathe Easy, Be Happy, and wait for the light to go out on its own.

Happened to my wife's Sienna, a Honda Civic I used to own, and I think I've seen it around once or twice on other cars.

There's nothing actually wrong with the car.

Sometimes a dealership will reset the light for free; mostly, they'll charge you something for the privilege. Note that if one actually had a broken gas cap/busted rubber gasket/whatever, the Check Engine light would be legit, they'd fix whatever-it-was, and clear the light while they were at it. But, since you know the cause, that's not the issue here.

Now, if you were planning to play with with code readings/scangauge/etc. anyway, then feel free, this is a great excuse. But if you're thinking you have to do this, well, no, you don't.

Sean: One like this should work for you.
