A coolant temperature sensor is confined to the engine of a vehicle and measures the temperature of the vehicle’s engine coolant. The sensor feeds this information back in the form of an electrical current to the engine control unit (ECU). The ECU then responds to a change in the temperature difference and readjusts the engine’s fuel injection.
