Inside the vehicle where the fuel gauge is, a little light
has appeared. Looks on 2008 Dodge Magnum

like a horse shoe with an ! exclamation in the middle. Is this a check engine light? Just came on. Fuel tank has been filled and its still on. I checked the cap where I fuel up on the outside to make sure it was on properly.
