Low coolant or bad sensor
The low coolant sensor is etiher plugded, broken, or your coolant is actually low. Check the radiator and resivor tank to see if they are full. If they are and the light is on, drain the coolant. Be careful not to break the plastic petcock. The sensor is located next to the battery on the right side of the car. Remove the battery and pull the sensor out. Clean it or replace it. then put everything back together.
