Temperature sensor, coolant, engine management system (202)

The temperature sensor measures the engine temperature. ECM uses the reading to deliver more fuel to the engine when the engine is cold. In addition, it can protect the engine against harmful overheating because the control module will limit the amount of fuel if there is a risk of overheating. The speed of the radiator fans is controlled by the engine temperature.
