P0128 reading on 2006 H3
Check engine light just came on the other day, got it read and shows P0128. Coolant Thermostat (coolant temperature below thermostat regulating temperature).
Any suggestions for what might be wrong?
Temperature gauge still reads normal temps and the interior heat is working fine as well.
Thanks

In my case it was the thermostat. The first time it happened, we found the cracked radiator. Replaced it and thought we were good. About a month later, started throwing the code again. Replaced the thermostat and it is gone. H3 showed no signs other then the code.

I to paid the dealership (used my GM points to get it for free). There is a thread that ended on 12/30/11 that explains where it is and how to replace it. I don't know how to insert the link or I would for you. Either look back by dates or search on thermostat.
