Check Engine Code p0128
2002 Bonne 130,000+ miles. Original Stock Tstat.
I guess from what I can gather on here that this code is generally fixed by installing a new Tstat correct? I have already replaced the temp/coolant sending unit.
Is a factory 195 tstat fine or should a guy go aftermarket with a 180? If so, someone have a good site or part number to purchase?
Anything else that this code sometimes points to?

DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
Tsat is the most likely culprit. Does the 2002 have two temperature sending units?

I just got that code too, is it possibly cause I have a 180 and with it being so cold its just not getting up to temp the pcm wants.

My drilled 180 took me through all of last winter without an issue. This year, it'* already throwing that code...even after I put the sight shield back on. Looks like I'll be swapping out to the 195 for the winter.
