Sometimes 60 degrees or more. I have changed the sensor as well as the connector with no change. What else could be causing this?

Good afternoon,

Where was the location of the sensor you replaced? there are two sensors. One for outside temperature and one for inside temperature.

You need the inside sensor. That is the one reading wrong.

So the inside sensor controls the display for the outside temperature? What is the part called specifically? There are three inside climate control parts listed on rock auto.

They work together on temperatures.

Cabin air temperature sensor.
