Code : P0456 Evaporative Emissions System - Small leak detected

So earlier in the week my check engine light came on. I bought a code reader and P0456 Evaporative Emissions System - Small leak detected came up. So I did some research and saw that it could have been as little as tightening the gas cap. But then I got another check engine light on today with the same code. Has anyone else had this issue and is there more to it than what I'm thinking (gas cap)? Thanks!

It's the gas cap. The system takes about 130 miles to reset itself. It will also help for a few months at a time, if you coat the gas cap's rubber ring with vasaline. It restores the plasticity and creates a better seal.

I'll try it. Thank you!

Right on the money. It is definitely the gas cap.
