U3F22 & U3F25

[Fenner408]

Ive got these two codes showing up every once in awhile since Ive gone to the single. Im pretty sure they have something to do with the VGT, but cant find any info on them.

Ucodes are usually communications codes.

Any idea where I could find more info on them? If it's just about the VGT being gone then I'm not worried, but they don't show all the time.
