Frequently Asked Questions (FAQs)

1. What does a temperature switch do in a car?

The Coolant Temperature Sensor is used to measure the temperature of the engine coolant. The readings from this sensor are then fed back to the engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing.

2. How do temperature switches work?

They are typically comprised of two metals, which generate an electrical voltage after a change in temperature has been identified. Temperature switches work in a similar way to an electrical switch, being turned 'on/off' in response to a specific fluctuation in temperature.

3. Does the coolant temperature sensor control the fan?

On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it's not working, the fan won't turn on when it needs to, which means the engine might overheat.
