Unhappy OAT pegged at 122F

The other day I added a connector to my Alpine head unit so I could play my Rio through the system. As usual precaution when moving electrical gear around, I disconnected the battery. It stayed disconnected for an hour or so while I took some calls. When I re-connected power to test the connector I noticed
OAT decided to peg itself at 122F. Figured maybe it was a reset value based on power loss, but after driving around for a bit it dropped into the 80s range (in 60 temps) then back to 122 so now I'm wondering - dying/dead sensor, short, ??? Lacking a diagram for the sensor & cluster I'm at a bit of a loss, curious if anyone has experienced similar on their STi.
