04199809

04199809 is a Deutz water temperature sensor. It is a sensor that measures the temperature of the engine coolant. This information is used by the engine control unit to control the cooling system. The 04199809 sensor is a thermistor. This means that it changes its resistance depending on the temperature. The sensor has a probe that is immersed in the engine coolant. As the coolant temperature changes, the resistance of the sensor changes. This change in resistance is measured by the engine control unit. The engine control unit uses the signal from the 04199809 sensor to determine the temperature of the engine coolant. This information is used to control the cooling system. If the sensor fails, the engine may overheat.
