07 Malibu Check Engine Code P0128

I have an 07 Chevrolet Malibu (v6, 3.5L). My check engine light came on and the code that is coming up is P0128 (Temp out of thermostat range...). My temperature gauge remains on "C" even when the car has been driven for a while.I also have no A/C it just blows warm air when the A/C is turned on. Is it my thermostat?
