What sensor controls the cooling fans? On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor.
Does the coolant temperature sensor control the fan? The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. … As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
What controls the electric cooling fan? The PCM controls fan operation; it uses the signal from the ECT or engine coolant temperature sensor. This sensor senses the temperature of the engine’s coolant and sends a variable voltage signal to the PCM. The PCM operates the fan motor through the engine’s cooling fan relay.
What causes cooling fans not to come on? Six things may prevent an electric cooling fan from coming on: … Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay. A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)

What does low voltage o2 sensor mean?
A low voltage signal from the oxygen sensor indicates low oxygen content in the exhaust—a sign that the engine runs rich. … Conversely, a high voltage signal shows high oxygen content and warns that the engine runs lean, leading to the PCM increasing fuel to compensate for the excess air.
