Outside Temp reads 10-15 degrees high...already replaced outside sensor 2x

by Mike

My outside temp on a dual zone started reading very high. 100's when outside in mid 70's. Voltage @ connector approx 5v. Replaced outside temp sensor. Then reads approx 10 - 15 degrees high. High 70's when outside is mid 60's. Thought as a fluke may have gotten bad new sensor. Just installed 2nd outside sensor. Still about 10 -15 degrees higher. Where does the signal go from the sensor...where is the "logic" calculated for the dash reading? Is it in the Dual Zone Controller or another computer in the vehicle somewhere?
