If your cap is not performing right, replace it, your engine needs the correct amount of pressure to keep the coolant from boil over, however if the level is correct cold anf the light is still on then the chances are high the the sensor itself has gone bad, not really uncommon for then to do so.

Unplug the sensor. If the light goes out the sensor is bad. You can try cleaning it but it usually requires replacement. If the light remains on with the sensor unplugged there's a short in the wiring going to the sensor or the instrument cluster is bad. HTH. -Jim
