Is my cylinder head temperature too high? I have a 2001 2.3 Ford Ranger and apparently it does not utilize a coolant temperature sensor, it just has a cylinder head temperature sensor. The electronic scan tool I use pulls the coolant temperature from the CHTS. ( I know this because I unplugged the CHTS and the scanner read -40) I tested the voltage with corresponding engine temp readings and the voltage appears within range. I am running about 260 CHT @ highway speed and 240-250 CHT at slower speeds. The car is not overheating, no boiling. Some Ford forums say this is normal, others say it is too high. Can this just be normal operating temperature?
