I have a 2012 Dodge Avenger and just recently the gas cap light came on where it shows my mileage, then I had my father take the negative end of my battery to reset it and it was good for two days, now it's back on and my check engine light is on. Ideas?
Answers from the Automotive Experts
Haley,
You may need to simply replace your gas gap, surprising because it is a newer vehicle, but the seal on the gap may be failing causing this concern. This is an inexpensive beginning to determine if further diagnostics is needed.
Greetings Haley,
What your Dad did with the battery only cleared the codes on your car's computer sets. This does not fix the problem.
Did you check the gas cap to make sure it was on correctly and was tight? Could be the gas cap is has a problem which would have caused an evap leak which would have made the check engine light come on.
Step 1 - check the gas cap.
If it's missing, not tight or screwed on wrong - fix it.
If the gas cap is fine - then take it to your shop to have them diagnose the problem.

You have an evap leak in your system that may have nothing to do with your gas cap. If you take it to a reputable shop, they can determine where the leak is coming from and tell you what it would take to fix it. Just turning off the light will not correct the issue. After a drive cycle, you said it came back on. You need to diagnose the problem. Do not just assume it is the cap.
It needs to be scanned by a mechanic! Shop around, some places do it for free and can give you an estimate to repair.Contribute to this question:
