Thanks in advance for your time and input! Looking for Cylinder Head Temperature (CHT) Sensor location? Along with any input. Coolant is fine, engine is not overheating but a fan keeps kicking on. Check engine light turned on while driving and vehicle stalled. I did a reset code with OBD2 scanner and was able to get vehicle home. Initially started with heater blowing cold air, not getting hot. I will also be replacing the thermostat.

It sits in the valley of the engine under the intake manifold. The intake has to be removed. Most of the issues that I have had with this code has been mice escaping the winter cold and chewing the harness up. If that is the case, repair the wiring.
