My engine light is illuminated, but there isn’t any codes showing up.
Any ideas?
2015 JKU, all stock powertrain. Starts, drives normally, temp and oil pressure are in range.

Could be as simple as a loose gas cap. Tighten it, clear codes and see if all is good in a few drive cycles. If not, may be something else. An EVAP leak won't cause any driveability issues, but it will piss off the greenies if they find out.

Thanks. I did tighten the cap and clear the code. The cap was loose. I kinda think someone might have tried stealing my gas last night. Last time I gassed up was last Thursday. You would think that it would have thrown the code sooner.

It doesn't trigger on a full tank. Usually won't pop until you get down to 3/4 or half full.
