Found this. Maybe it'll provide some insight? Apparently it is only used as diagnostics, and can be disabled without too much worry (although if it were me, I'd try to solve the problem, just like you, and keep it activated).
Definitely something to do with the evap solenoid and it's fuel line.
Double check your purge line. Make sure it isn't clogged/restricted.
