I am trying to learn how to calibrate my 2006 Solana TX temperature setting. The screen reads 104F, but the actual temperature is 101F. I tested the thermostat sensor with a ohm meter and it reads 5.6k ohms. It seems to be within the appropriate range based on temperature & Ohms Value. Is there any way I can calibrate the actual display so, I can actually get the water temperature up to the desired 104F?
