Low coolant or bad sensor
What type of coolant sensor? The below answer is for the coolant LEVEL sensor. The coolant TEMPERATURE sensor on my vehicle is located just next to the thermostat housing. On the front top center area of the engine just behind the radiator. Follow the coolant hoses if you have trouble. On my 1995 Jeep Grand Cherokee the sensor is located on the top of the plastic coolant reservoir tank. Look for a small (2-wire?) electrical connector.

he radiator
I know there is one on my 97 Cherokee on a radiator hose housing just in front of the cylinder head. (there are three coolant hoses going to the housing). I have been told there is another one on the radiator but i havent found it yet. I was also looking for another sending unit, but the service manual for a 2000 Cherokee says that same ECT sensor on the thermostat housing also drives the coolant temp gauge, thru the pcm. I think earlier models had a separate coolant temperature sending unit on the cylinder head driver side rear.
