This problem was actually noticed on 2000 Chev Monte Carlo 6 cyl.,but this problem is noticed on many other car models too.
The Temperature sensor dies,after replacing the sensor,it again dies in few days.
Basically in this case the temp gauge stops working and replacing the Temp sensor makes it work,but again temp sensor dies and temperature gauge stops working.
Basically in this cases the steady Check engine light comes ON dash.
And scanning the computer module of the car gives error code........
The code P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).
This code is almost always set because of the thermostat opening too early. The computer sees the engine has not reached a set temp in a set time and assumes there is an issue. The code is actually for the coolant temp sensor, but if replacing the sensor not helping then, Replace the thermostat and see. It is not an expensive part.Basically when thermostat opens too soon it thinks there is an issue with the sensor so it disables it.

This details should help you.
Thanks.
