Question about 2008 Chevrolet Impala
I have a 2008 Impala, whose outside temp. gauge indicates a -40 degrees when it could be 80 degrees. I noticed on the internet that I am not the only person to have had this problem. I took it to the dealer, they changed the sensor, said they cleaned some corrosion, charged $125.00 and the problem still exists. I could not find a solution on the internet. I did notice that when there is excess moisture like rain, wet payment, and car wash the temp will drop to -40 degrees. What is the solution?
You have a water intrusion problem. The first step is to locate where the water is coming into car. The water is apparently getting in the wiring harness.

Testimonial: "This problem occurs also when it's 90 degrees out and no rain for weeks. I can start the car and it indicates -40 degrees. I don't believe this is a solution."

If I were you I would replace the thermostat. It's cheaper and usually takes less than an hour to change. Before you install the new one, put it in a pot of water and heat it up using a bakers thermometer to check and make sure it opens at the right temperature. I've had bad t-stats right out of the box. Maybe I just have bad luck!

Welcome to Fixya
Check the physical wiring of the radiator Fan. there might be loose wiring. I suggest you direct the wiring to the ignition switch. So that when you turn the key to ON position the fan will engage right away. Overheating engine might damage serious parts inside the engine.
Thank you for usig Fixya!

If you replaced the right sensor, there must be a problem in the wiring to the computer.
You did reset the computer - hit ac and recirculate buttons at the same time ??
