I keep getting code P0128.
First I checked coolant level and it was fine.
Next, that weekend I drained coolant and replaced thermostat (Napa)(G-05 Coolant) reset and check engine light went away for about a week.
Light comes back on about a week later so I replace the Coolant temp sensor and reset, light has now come back on when wife was driving home from work. I am kinda lost as to what I should do at this point as was hoping someone might have some info. My heater seems to work fine and the temp gauge is sitting where it always has. Is there anyway to tell if the new thermostat I put in is working? Can you tell when it opens up?
