Thumbs down EATC Outside Temp doesn't update

I have '05 F250 King Ranch with EATC. I outside air temp doesn't update, it remains constant at the initial reading at start up. I have run the self test routine and the fault detect routine with no porblems identified. The funny part is that after exiting the self test routines the outside temp seems to update normally, but after an ignition off time the problem returns. All other parts of the ETAC seem to be functioning normally.
Any idea?

Do you get any reading or what do you see?

Could be a bad sensor, bad connections, or bad head unit. The last one is the pricey one to fix...
