hi, I'm having a code show up that coolants below threshold temp on a chevy impala ss indy edition. 3.8 series 2 supercharged. Could it be because its cold outside(17 deg. F.) and the s.c. forcing the cold air thru motor? or the temp. sensor? please note that when I checked the graph on the code reader it was spiking and dropping radically. While the temp. gauge appears to remain steady. Blows hot heat but sometimes takes quite a while to warm to operating temperature. Could it be thermostat AND sensor. 125,000 miles never been changed. :o :shock:

The most likely cause for the P0128 on your Chevy is a bad thermostat. That is why the temperature is going up and down so much on your scanner. The gauge should move accordingly. 10-15 degrees might not show on the gauge. But, it is possible the temp sensor is bad as well. I would replace the thermostat, bleed, clear the code and re-check.
