Why do the fans come on when I Disconnect The Temp sensor?
Since the fans turn on when the temp sensor is disconnected, it can’t be a fan relay. It must be the 2 wire temp sensor or the ECU. Most likely the temp sensor since when it’s disconnected, the ECU turns the fans on.
Can a faulty coolant temperature sensor affect cooling fans?
A coolant temperature sensor is a vital part of an automobile engine’s cooling system. Without a properly operating cooling system, the engine will run hot which will cause the engine to operate inefficiently and may result in serious damage. Coolant Sensor Purpose
How does the ECT sensor work on a fan?
It is a simple system as cooling fans go. The ECT sensor tell the PCM the temperature, at 209 degrees the PCM sends a pulsed power signal to the fan control module. That signal keeps getting faster as the temperature rises. The control module gets that signal and uses larger power transistors to pass the pulsed signal to the fan.
What does CTS stand for in a car?
The coolant temperature sensor, abbreviated as CTS, in your car is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason.

What does the fan sensor on a Cadillac do?
The fan sensor, or cooling fan control switch by its more popular name, controls the operation of your Cadillac’s radiator fan. When the coolant within the radiator reaches a specified temperature, the sensor activates the fan.
