Function of intake temperature sensor
The intake air temperature sensor determines the intake air temperature and passes this on as a voltage signal to the engine control unit. These temperature values are essential for optimum combustion. This resistance sensor varies its resistance with the temperature: a higher temperature reduces the resistance and reduces the voltage.
The engine control unit interprets the voltage values that are directly related to the intake air temperature - low temperatures lead to higher, high temperatures to lower voltage values at the sensor.
