Need Help!

I was just coming home from work in my 07 Tahoe LT. I was cruising and seen a cop. I looked down at my gauge cluster to see how fast I was going. Right after that my temperature went from 210 to 160 and on my DIC I seen Engine Hot / A/C Turned Off. What could be the cause of this??

Did it stay that way all the way home?

nope. I like about 10 mins from my shop. It came on about 2 mins from my house. Its been sitting for a hour. I went outside and started it. Still shows the same message and the temperature gauge wont move

nope. Check engine light isn't on and didn't come on when I was driving either

If its a failed shorted temp sensor it should have thrown a code. I think there is a code because it came up on the dic. If no code and truck runs fine could be a stepper motor in the cluster. Can you get your hands on a code reader?

It ran find the whole time the message was up. No I cant. Im looking for a mechanic that can look at it today. The dealership cant look at it until tomorrow and this is my only ride for work.

A pep boys or autozone most large parts stores will pull the code for free in case the dealer is going to charge you.
