Kia Forte: Air Conditioning System / Photo Sensor
Description and operation
The photo sensor is located at the center of the defrost nozzles.
The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar
radiation received by its light receiving portion, generates an electromotive force
in proportion to the amount of radiation received which is transferred to the automatic
temperature control module so that the solar radiation compensation will be performed.
