Also try getting the IAT2 reading with no sensor plugged into the harness, then plug it in whilst reading the IAT2 see if that resets it.

Other option is pull your ECU fuse out for 30min and see if that resets anything.

Check and clear any fault codes.
Insure you MAF is also plugged in whilst this is IAT1 it may play a role.
I did try unplugging the wire & I got check engine straight & I am sure it is reading but reading high , all other connections are ok & IAT2 reads higher than IAT1.

Wire is ok for sure.
