Gascap need anewonehowtoorder

The "gascap" warning tells you that there is a leak somewhere in the fuel tank, fill neck, or gas cap that is preventing vacuum from developing in the tank. If you are certain that your gas cap is good, the second most likely culprit is the fuel fill neck gasket was compromised during the accident, or that there was unnoticed damage to the gas tank which is not allowing a vacuum to develop inside the tank.

Start by rebooting the as explained regkyl.
If issue returns then get a new gascap and reboot again. The seal on your cap is maybe worn out.
If issue still return then you'll have no choice to go and have the sensor checked and hope the problem is not with the cluster...

basically what you need to do is to check the oil gascap see if it has any type of dirt or anything under, if so just clean it off. the gascap should be on top of engine where it says OIL. or the gas cap could be rusted and may have to be replaced

The gascap light means you may not have the gas cap on tight, or it may be faulty. The check engine light means the computer has found a problem that will affect performance and-or emissions.
Such as a leaking gas cap.
If the gas cap is ok, you may need to get the computer scanned for trouble codes to proceed with testing.

the check engine light is most likely evap system large leak which is what causes the gas cap light it probably needs a nvld pump or it has a leaking evap tube under th vehicle.

Hello, what did someone do to repair it? Here is what you need to do. Go to Autozone or Oreillys and get a free scan. If it still shows gascap then ask them to clear the onboard computer. With the engine off, tighten your gascap again.

Everytime you put on the gascap loosely, you will get this alarm and it will stay on 25-35 Startups or until you get the computer cleared.

However, if you eliminate the gascap there are other problems which you may have that require a special tool called a smoke machine. You have a leak in one of your pollution hoses for the fuel tank. Only the smoke machine can find a small leak like this. Once you find the leak it is a simple matter to fix.

You can call around to find a repair shop with the proper equipment. I hope you find my solution informative and feel well served.

You may need to reset the codes to get the light to go out

It might take 2 or 3 gas fill-ups before the light goes off. Don't worry.

You will need to get the code befoe anyone can begin to diagnose this, There are about 5 parts that can cause this problems. The gas cap is one of them. If anyone has been uner the hood just pryor to this happening its possible they left a vacuum hose off or maybe broke one.

If this car is really an 07 then this being an emission issue you are covered under warrenty. Take it to the dealer.

you have a bad gas cap replace it with a new one
they old one is not sealing right
