Engine Air Intake Temperature Sensor (Opel Frontera B)

The engine air temperature sensor is a thermistor whose resistance changes depending on temperature. The engine control unit takes into account the sensor signal and adjusts the pulse width supplied to the injectors, which changes the amount of fuel supplied to the engine cylinders and also changes the ignition timing.
