I get the message "Engine Hot, A/C turned off" but engine is not hot

What is your question?

Out of the blue my message screen reads "engine hot a/c turned off" and the air won't work. Also the temperature gauge stops working at the same time. After a while it starts working like it's supposed to. The first time this happened my husband checked the engine temperature with a handheld temperature gun and the engine temperature was fine. Can it be a sensor or something messing up?

What makes this problem better or worse?

Nothing makes it better or worse.
