That doesn't mean that there is not gas escaping from it. Sometimes the seal isn't good and it will leak. I have actually had that problem and it didn't seem like the cap was bad at all. I replaced it and problem went away. So you probably wouldn't even know if it wasn't for the light. Hope that helped you out.

Usually this means you just need to replace the actual gascap itself. The plastic must not be sealing tight enough. If that doesn't work then you have to see it the sensor is working properly.

Engine light on & gascap

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.

About a month ago my gascap light came on on my 2008 dodge avenger. I replaced it with a locking gascap and about a day later it went away. Today it came back on. What could the problem be?

these are sensitive to the gas cap being installed properly and tightly,if not then the light will come on,this is a system that performs a pressure tested system under the right conditions to make sure there is not a leak in the vapor system of the emission system

Fuel cap light keeps coming on and then the check engine light. This was repaired two weeks ago and light came on last night.

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.

The gascap light is on and the oil light is on. They replaced the seal on the oilcap and they don't know what's wrong with it

try disconnecting the battery to clear the codes. then make sure the gas cap is tight, should make it click at least 3 or more times. if the gas cap light comes back on its possible that their is a leak in the EVAP system. as far as the oil light coming on its a possibility that the oil pressure switch is bad.

Gascap light comes on every time I start the car.

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.

check the o-ring under the cap or just replace cap,dodge uses a system called leak detection with a small pump to put vacumm on the evap system if the system fails to hold vaccum then it is 90% time the fuel cap or bad vaccum line in evap system or purge valve.
