Hello! Welcome to justanswer!

 

That code is for usually leaving the fuel cap off while refueling or just a bad gas cap. Try replacing the fuel cap and resetting the code. The code means theres a large leak in the tank vent system. It will not make the engine run bad or cause a break down. In the worst case, the leak detection pump would have to be replaced.
