Temperature gauge stuck on hot!

[2020 PP2 5.0]

My temperature gauge in my 1994 mustang GT 5.0 is stuck on hot.I replaced the temperature sending unit and the CTS and had no luck. What should I try next?!

Is the needle pegged when the car is off? Does it go right to the peg when the KOEO position? Give us a little more detail.

The needle is pegged when the car is off and on at all times. It slightly moves back when I start the vehicle but still doesn’t make it out of the H!

It's probably a bad gauge. I am sure there are ways to test for that, but no cheap ones. It's a very simple circuit, basically the gauge and the sender are the only two parts.

I'm having the same issue with my 97 gt. Did you resolve this issue and if so how?
