DTC P0128

2005 Chevrolet Trailblazer • 6 cylinder 2WD Automatic • 73,000 miles

2005 trailblazer posts a DTC of P0128 but dash guage shows normal reading, Freeze frame says coolant temp is 179 degrees F. I can clear the code but returns after a little driving? Does this indicate a defective sensor?
