    If the radiator is full, there's either an air bubble on the sensor, the sensor is gunked up, or it's just gone bad. It's on the side of the radiator under the filler neck. A lot of people just unplug it, and the light goes off.

    If everything in the cooling system is good (coolant levels, bled properly, etc), then the issue is probably with the sensor itself. You can try taking the sensor out and cleaning it. And also clean out the hole where the sensor goes in. Sometimes this can get all gunked up and give weird readings.

    I simply unplugged mine since I check mine frequently and don't see it as an issue.
