Hyundai Palisade: 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.
Repair procedures
1. |
Emit intensive light toward the photo sensor using a lamp, and check
the output voltage change.
|
2. |
The voltage will rise with higher intensive light and reduce with lower
intensive light.
