    I wish I had an answer. I have exactly the same problem. I replaced the outside air sensor and it made no difference (at least the part was under $10 and took 10 minutes to replace). It is just at the front under the plastic cover and just snaps into a bracket and the connector plugs in.

    I am afraid that they will tell me it is a computer malfunction and will want hundreds to replace.

    I had a similar problem with my Silverado and the dealer loaded new software on the computer and the issue went away. Only cost $160 (ha ha.).

    BTW on my Impala, the tire sensors don't work any more and they quoted me about $200 to fix so I have ignored it. I am not overjoyed with the computerized aspects of this vehicle.

    I have the exact same problem with my 2006 Chevy Impala, It's in the upper 90's and my outside temperature tells me it's - 40! It's fustrating. I think I'm going to see if I can find the ait senor replace it myself. I made an appt at the dealership I bought the Impala from they and want $45-$60 just to diagnosis the issue. I can only imagine what they'll charge for the part then the labor to replace it.
    Have you tried the suggestion of replacing the air senor that I saw following your post?

    I have the same problem. Mine will show either -38 degrees or -44 degrees. I took it to the shop and they could not replicate the problem. I asked them to order me a senson an replace it. $75 later, I still have the same problem. I spoke to the service manager and he's trying to find the answer.

    By the way, I have the same problem another poster mentioned about the tire pressure sensors, too. I've replaced three of them in the two years I've had this car.

    An instant OAT update must be performed by pressing the A/C and Recirc buttons at the same time after the system has been repaired to convert the A/C permission from out of range to normal.

    The sensor is under the plastic shild above the grille.
