My Gas cap light and engine light came on today. I shut the car off and retightened the cap and they did not go out. Do I need to reset the computer? if so which fuse is that? It's a 2010 challenger rt. Thanks

Fuel and venting system

Thanks JKelly16, After I started it a couple more times the light went out.
The OBD-II code is a two step code in that it will take at least two start
cycles for the code to clear after the first step is reset. This usually allows
the gas tank venting system to establish that a vacuum has been establish
and the gas tank pressure is working correctly.

The owners manual does touch on this a bit under the "Understanding Your Instrument Panel) but does not go into technical detail.
