If the code doesn't clear within 100 miles of driving then it is likely that you flooded the charcoal canister with gas. One should never ever fill a modern car past the point where the pump cuts off the first time. Reason for this is that the evap system which is complicated as all hell depends on a very small amount of vacuum on it and air filtering into the charcoal canister which absorbs gas "fumes" when the car is sitting and then "burns them" when the car is driven. If you overfill the tank then gas can flow back into the charcoal canister and the actual liquid fuel will destroy the charcoal as well as blocking the vacuum and setting the code. Canisters are 80 to several hundred of dollars on modern cars and there is labor, etc. to replace them as well. You might be able to check this yourself if you are mechanical by removing the lines from the canister. If fuel comes out you know what is wrong. If no fuel either remove or loosen it so that it can be pointed downward and see if any flows out. There are still purge valves and other things that can cause this problem and it might be a "coincidence" that this happened after overfilling the tank, but we have seen this happen so many times. Cost one of our customer's 300 bucks to fix this on a Chevy Blazer and about a year later he felt "lucky" and tried it again. This time we got him a used one as he was trading in anyway. :-)

This has happened to my pursuit a few times. My gas cap wasnt on properly and/or the dealer told me there was debris on the cap preventing suction.
I think once maybe it happened because we had a really bad down poor of rain, and my windsow was slightly open. Things may have got went.
Neither of the 3 times I recently gased up, which apprently is the usual reason. I don't know why.
My car wasn't in any trouble. If I knew how to turn it off my self I would have.
The dealer also replaced my cap after the 3rd time it happened. I haven't had a problem since, and that was a few months a ago.
I should also ad that first couple times the dealer ran tests that didn't fail. Everything checked out fine so I guess things were fixed on their own but the car didn't clear the code itself.

If you car is actually saying check gas cap and not evap system malfunction then the problem is most likely a bad gas cap.Replace the cap first...

you need to drive the car until it runs the test again and clears the code by itself.
