The coolant temp sensor issue might have caused the thermostat code. The system monitors the Coolant temp sensor for the thermostat code. The wiring circuits could be shorted or open? Did you check ref voltage at the coolant temp sensor? 5 volts goes hot with the key on. The ref voltage is usually a shared circuit. So it is possible another sensor or circuit could be causing a problem?

I haven't checked about the temp gage on the dash.
