Outside Temp control reading going nuts
 

My outside temp control readings are all over the map.
I started the car last night (In Houston) and the reading was giving partial numbers like a cheap wrist watch when it gets wet.
Then it went up to +112 and started counting down to (- 15+.
I turned the car off and restarted. It went to correct temp and then started the game again. . I went to the store and came back out and did not pay attention on the way home....What gives

Sounds like the sensor has gone bad. Easy to replace.
