Nyet about the sensor. The ECU sensor was changed three times. It has a genuine MoPar replacement now. That is the sensor the fan is controlled with. The temp gauge sensor was only changed twice. Both sensors are near the thermostat housing and EITHER sensor when malfunctioning throws a check engine code and everything goes into limp-home mode.
The thermostat bolt sensor has me intrigued -- especially since I cannot find any online.
Never ran into a fan control sensor in the block, ECU and temp gauge yes but fan control in the radiator. Usually near the radiator outlet where the cooled water returns to the block.
Having said that: I don't know the year of your rig so am going by what i have replaced only. Yours may be newer and different now. A lot more complicated--ah yes technology!
