Temperature coolant sensor you meant. Check the coolant level and check the hoses from the radiator if are hot (just touch and let go). This would show if the thermostat is ok. Also you could step out of the car and leave the interior fan on the highest mark to see if temperature is coming down. A bigger problem could be a blown headgasket...

I just had the same problem this morning. My coolant wasn't low. I had the heat on high trying to warm my car. The engine didn't show signs of overheating and I added more coolant. Temperature hand is stock on cold. Pretty sure it went out...
