The ambient temp sensor is located behind the front bumper, I think passenger side. Usually when they go bad, or a short in the circuit, the gauge will read -22. You can check the circuit by=== http://www.lexls.com/tutorials/air/accodes.html
If it was ever unhooked you need to reset the gauge by pulling out the DOME fuse, under the hood, for 30 seconds.

ambient air temp sensor for the CC has absolutely nothing to do for the ECU....
