Check the coolant level in the reservoir. If that's up and the vehicle isn't overheating, you probably have a 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.
Low coolant or bad sensor
Either do to a coolant leak or a failed coolant level sensor.
Low coolant or a defective sensor
they are at the bottom corner of the radiator.
Underneath the alternator
The engine coolant temperature sensor has nothing to do with the low coolant light. The low coolant sensor is mounted in the bottom of the overflow/filling reservoir by your washer fluid bottle. You will need to verify that the coolant overflow/fill bottle has coolant in it and if it does then the sensor is bad and will have to be replaced.
