Help temp coolant

Good afternoon, I’m having a problem with the temperature marker. I’m using ESP and the values are from 0 to 4095 to map the temperature. I get the values, add them to the temperature text gauging, and adjust them in the custom map, but the temperature is getting stuck at a fixed value and rising rapidly, then it stops. It no longer fluctuates like it did before when calibrating in the custom map. Before, everything was ok, but now it’s stuck with values in this version 2.6.8.
