Make sure there is no coolant leaks, and that the operation of the cooling fan is working, when the engine is at operating temperature and not over heating. With the engine off, the cooling fan should have resistance in the direction of its movement. If this condition is just sensor problem you would have to remove the intake to change the sensor ,
