What is the sensor on a Mazda 3 behind the radiator?

2006 Mazda 3i. I have a P0126 code for insufficient temperature. I know this is commonly caused by the thermostat, however, there are two sensors on my car directly behind the radiator. The mounting bracket is broken on one side so one of the sensors is simply laying there. Is this related? If not, could someone please inform me of what these sensors are?

Thanks for any helpful info
