Code 2772, tank vent valve activation on 2003 3.0?

[SamuelL421]

Started getting this 2772 code a week ago and I'm have trouble finding information on it. I've cleared it and it seems to come back within a day - so it seems to be legitimate (not a one-off computer quirk from a 15 year-old car).

The code comes up as "Tank vent valve activation" when I search for this or vent / purge valve then all I find are posts and videos about error codes 0442 or 0440. These seem to be referencing a different vent valve from the one in the 2772, but I can't find any information to verify that or not.

Is anyone familiar with this code or know which valve 2772 is referring to?
