This could be a bad thermostat, stuck open all the time FYI.

The P0128 code on your 2009 Saturn Aura indicates that the engine coolant temperature is below the thermostat regulating temperature.

Here is the location of the engine coolant temperature sensor. Check out the images (below). Let us know how it goes.
