Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
I replaced a broken Gas Cap 2 weeks ago and the Check Engine Light came on 1 week ago. I got the code P4055 today - and am hoping that the New Gas Cap will fix the problem. How can I reset the Check Engine Light?
In the Saturn Vue, the gas cap release is typically located inside the vehicle, on the driver's side. You can find it near the driver's seat, often near the door or on the floor near the left side. To open the gas cap, simply pull the release lever or push the button, depending on the model year. Once released, the gas cap can be accessed from the outside at the fuel door.
your gas cap may not be installed correctly

Check your gas cap. I had a 2402 on my S40 and the gas cap was bad, easy fix...
It means that the EVAP system senses a leak in the gas cap, or filler neck. The most common problems that cause this, are a loose gas cap, or a defective gas cap.
If the Suburban is E85 ready, but the gas cap says to avoid it, then avoid it until a check with a mechanic can be made. The gas cap might be a replacement gas cap if the vehicle was purchased used.
Check your gas cap to see if it is on right. I had that once and it was my gas cap not being on right.

No, a loose gas cap can cause the check engine light to come on but not the low fuel light.

Could be a defective gas cap (bad sealing gasket?)
