I took my 2012 CS to the dealer a few weeks ago to have the radio reprogrammed on a recall for this car. Now the outside temp sensor stays at about 60-62 degrees. Now I live in sunny southern california and the temp is usually about 70+ (all the time). Even in the middle of the day the sensor is reading 62 degrees. Is there a programming problem? Do I need a new sensor? where is the sensor? I don't remember the gauge being off so much. The car has over 100k miles.

 

I believe you have to remove at least part of the wheel well liner to see this spot. Good luck.
