I have a 2003 XLT V6 4X4, and the "Service Engine Soon" light came on today. I had the local auto parts store read the code, and the printout was:
P0128
Coolant Temp
Below Thermostat
Regulating Temp
I suppose that the problem could be a coolant sensor or the thermostat itself. Does anyone know which is more likely? If it IS the sensor that apparently is a dealer-only part, as the local auto parts stores don't have it and can't order it.
Thanks in advance for your help.
