For those who were able to resolve the P0456 code with a new gas cap.... how long did it take to go away?

I installed a new gas cap, and am wondering if that was the fix. The CEL is still on.

Otherwise, I'm gonna have to keep at it.
 
Thanks everyone.

The CEL light went away within 2 days and a fill up.

Hopefully that resolved the issue.

Fingers crossed, cuz in the past, the light intermittently turned off and on.
