Hi there. If this came on as the fuel in the tank was very low then it can cause some false codes. You can add more fuel and drive it for a few days to see if it will reset. If it is a simple emissions code, then it will reset on its own. I usually start by scanning the computer for codes to see what is coming up. It is possible that it is a bad gas cap or even another sensor in the system.
