Hi
Recently I scanned a trouble code P0128. Seemed pretty straightforward, I replaced the thermostat. Check Engine came up again with the same code (after clearing original). Next, I did the next obvious thing and replaced the Coolant temp sensor. I didn't reset the code just to see what would happen. After a couple of cycles, the check engine light went off, so I figured that I fixed the problem. However, it came back on AGAIN with the same P0128! I noticed two things: 1) when the weather is warmer, the light just goes off by itself, but soon as it gets colder the light (and same code) come back, 2) when it's colder it seems to take the gauge longer to get to op temp, i. e. I'll be driving for a long while and it stays at 1/4, after a while it goes to mid to slightly past and the fan kicks on as normal.
I would really appreciate some feedback.
Thanks
