I have a 2012 optima ex. Ambient temperature readings are erratic and causing issues with the heating and cooling inside the car. I replaced the ambient temperature sensor in the front of the radiator with an original oem sensor made no difference. Also seem to have a little rough idle not too bad not sure if related.
Looking to see what the real issues could be.
Any help would be great. Thanks
