Hi, 2015 Hyundai santa fe, 80 000 miles. Got codes P0449 , P0451. My mechanic replaced purge valve, and vent valve. He also needed to replace connector on vent valve as he said it melted to it. I drive it and same codes came back. He said it's either wiring or computer. The computer is $1200 +. If needed. Would this really be a computer issue or are there other things that could cause the issue.
12k miles in one week? That was quite a drive. Hope these links help you before you throw even more money into it:

@g-t sorry, should be 68 k. In my amateur research it points toward the fuel tank pressure sensor or a wiring issue. Would you think it would be a computer issue?
It could be. I'd rather check the wiring first.
@g-t thanks, it's going in tomorrow
