Question about 2006 Hyundai Sonata
> internal thermometer
Do you mean coolant/engine temperature or ambient air temp? If you mean the engine's operating temperature, then the temperature sensor is failing. This won't bother operation but you will also have no monitoring of operating temp in case something is awry with the engine.
Such sensors are fairly common failures and not terribly expensive to replace.
