Hello, I have a question. I've had the check engine light come on twice now, and the problem has always been a P0128 code. This issue occurred when the first cold weather arrived. The check engine light goes away on its own after a while, but I'm concerned that my car runs at 70 degrees Celsius during regular driving and doesn't warm up at all when idling. Is everything okay, or is my thermostat broken?My car is really important to me, and I take very good care of it. I'm always concerned if even the slightest unusual sound comes up, but this issue is worrying me. I've tried to find other possible causes for the problem, and I found out that the battery can also affect this issue.
Thank youu!

You will most likely need a thermostat replacement. Might be partially stuck open not letting the car get up to proper temperature.
