Default Questions about P1447

My car (2003 WRX) is throwing a P1447 and I can't find much info online..

I did, however, find something online about the gas cap-

Is there a sensor to see if I filled the gas recently? I was thinking if I undo the cap, put it back on, and start the car it might clear it. The code came on after I had gotten gas ( I think I rememeber correctly..)

If not, anyone have any insight on what to check here? The car is under warranty, so the dealer is fixing it for me ...

If I can fix it by myself I see no reason to waste time at the dealer.

i was troubleshooting an evap code for 2 months and the blue t connector was the exact issue. the t part snapped and was creating the small evap leak.
