How to check the gas cap on a jeep cel?
If it does, pull the codes (though it is likely P0457 and/or P0456) to verify that’s what is tripping the CEL. If there is still a problem, I would start with the simple and cheap solution – get an OEM gas cap. Visually expecting the gas cap may not reveal a failure in the seal. Clear the codes and try again.
How can I tell if my gas cap has failed?
Visually expecting the gas cap may not reveal a failure in the seal. Clear the codes and try again.

If there is a leak, you will likely be able to smell it if you stick your head under there.

You can either tighten the cap and wait for the system to reset itself when it determines the problem is fixed, or you can use an OBD-II code scanner to manually reset the system.

Why does my check engine light say gas cap?
First it wasn’t saying gas cap it was just a check engine light. I read it with the flashpaq and it had a small evape leak code. I immediately checked the gas cap and it did feel a little loose. I tighten it and cleared the code. It came back on again so I then thought maybe it was ba bad gas cap or a leaking seal around the gas cap.
What kind of gas cap does my Jeep Wrangler use?
What is strange is that when she buys a certain brand of gas it usually doesn’t show up, but it will with another. She does have an aftermarket (Stant) gas cap which I think is the route of her issues, but she refuses to let me buy a MOPAR cap.
