OPERATION
The intake air temperature sensor functions to

convert the
temperature of the air (intaken to
the engine) to voltage, and to input that voltage
(as signals) to the engine control module. The

ature sensor, which is a type of resistor, and is
grounded at the engine control module.
Note that the resistance of the intake air tem-
perature sensor decreases when the tempera-
the intake air temperature sensor increases, and
becomes lower when the resistance decreases.
