Well, if you unplug the sensor connection and the fan runs then that rules out the fan and relay. That leaves a couple possibilities. One being it’s not getting hot enough to need to run. There’s an air bubble in the system or the sensor is no good.
What does your engine temp gauge read? Is it in the normal range when hot?
Do you get hot air from heater?
If temp gauge reads low but engine is hot, the sensor may be being fooled by an air bubble in the cooling system. They tend to settle at a high point, often where the sensor is located.
If the gauge reads normal range and you get hot air from heater, the replacement sensor may be bad.
