Okay so i got a cel code and i'm hoping i can fix the issue that is causing the code to pop up. Well i scanned it at AutoZone and their scantool said that there were two codes except i was only able to read one. I suppose that they are both related but anyhow can someone tell me what P0128 is and what would cause this code to be thrown? TIA

 

All I can find is coolant temp sensor out of range.

 

what does that mean? How can I fix this?

 

Either the coolant temp sensor is bad or the thermostat.

I would replace both to be safe. Plus the sensor is easier to get to once you remove the upper thermostat housing.

 

I have the same problem and have an appt. for fix it. The local dealership says they replace both the thermastat and sensor to assure the problem is fixed. I was quoted 229.00 total at Volvo in Salt Lake City.

 

Thanks! I will def look into this. Thanks again. How long ago did you get the CEL S Forty208? BTW if I wanted to do this myself, what kinda hassle am i looking at? or is it just a simple set of steps. Also I erased the code after the last scan and the light has not come on since, it seems to be happening only when it's freaking cold in the mornings. TIA!
