Air temperature sensor
Introduction
The engine control system on the diavel uses a sensor that measures air
temperature. This sensor has a resistance of
ntc type (negative temperature coefficient), that reduces its own value when the
temperature increases. The air
temperature sensor allows the engine control unit t ...
