I had the same problem. In fact, I had my thermostat replaced 3 times in 1 year. This lead me to re-think the problem. I had the same code p0128, low temp threshold. I couldn't imagine received 3 faulty thermostats. The final result was the Engine Coolant temperature sensor was faulty. It was sending low read reading to the onboard computer. Since the coolant temp sensor was replaced, no problems.

I had the same type of problem but mine was eratic working some times not working and a check engine light. I found the temp sending sensor and messed with the connection and wires and haven't had that problem ever again.

I had same intermittent issue, plus while it was happening, my remote start would not work. I replaced sensor and checked all wires but problem persisted. This year I replaced the factory wheels with custom wheels which forced me to replace the tire pressure sensors. That cured the problem. Somehow that was fooling and sending bad info to the computer, causing this annoying problem.

I am having the same problem. Only this morning on the way to work I ran over a piece of metal, sensor stopped working and check engine light came on? Is there a way that the metal could have hit the sensor?

I have a 2008 HHR. I found out why my car would shut down completely leaving my keys stuck in the ignition...RECALL! I wish I'd known this before my purchase. Now my problem is the a/c and engine light. I see the previous experiences from others so I will replace the sensory. Fingers crossed!

I had the same issue with the temp not reading and A/C not working on 2009 HHR. No needle gauge reading and --- reading for on board computer for engine temperature. I replaced the temperature sensor located on drivers side towards rear of engine (make sure to let engine cool down and use a drip pan) and it was still not working. I read how the on board computer can be tricked if any of the other other sensors are not working. I had a low tire pressure, so i filled the tire to specs. Still not fixed, and now the check engine light was on. I drove to the Auto Zone where I bought the temp sensor for $25 to get that code read. On the way there, the temp began to read, both needle gauge and onboard computer. The A/C was now working and now all I needed was a check engine light reading (TEMP SENSOR/THERMOSTAT). The parts associate told me to disconnect the battery to reset it. I drove it for a few more miles to make sure everything was still working well and the check engine light disappeared. At least now I know its got a new sensor and that my tires are properly inflated... :)

I had the same issue, replaced the sensor, no difference. I found the thermostat itself failed (stat was stuck and the seals had fallen off). The computer runs tests to detect this, and if it sees a failure it then purposefully kills the signal to the dash temp gauge until the stat is replaced and then codes are reset. Suprising but true.
