Guessing the gas cap is cause for both. CEL came on today after filling up a couple days ago (not driven much since filling). Checked the cap and it seemed like it wasn't even tightened at all. Odd.

Going on a road trip for a couple days. Hope everything is okay!

 

You can try checking or replacing the gas cap. But I would look at all the hoses or run a LDP test with scanner. Or you can try doing a smoke test.

 

Appreciate the input. After tightening the gas cap and getting through a drive cycle, the light went out. Very odd it was that loose.
