[QUOTE="Danarch, post: 441776, member: 21093"] Update - You all may think I am crazy. But I tried my theory. I cleared the code. My wife drove two days with no heater on in the morning and the temp rose and stayed right at 200 and no CEL light has come. So it seems that when its in the high 50’s - low 60’s and she uses the heater full blast the entire trip to work in the morning the coolant temp basically reaches a high of 185 and which in turns causes the the CEL light to come saying the engine is operating below temp. Other then this all seems normal, temps seem to be the normal operating range. Also this is only the case when the doors and freedom panels are off so obivisoly :)the cab never heats up . Which is why the heater is running full blast the entire time. [/QUOTE]
