4. SENSORS AND ACTUATORS
1) Sun Sensor
It is installed on the upper left end of instrument panel. It is using characteristics that the
amount of current changes according to amount of light on the photosensitive surface. Photo
diode, converts the changes in light intensity into electrical changes, detects the amount of light
coming through windshield and changes it into current and then sends the signal to FATC
controller.
(1) Inspection
Remove the sun sensor and measure the current between terminals under sunlight.
Measure the current again under shade. It is in normal conditions if the measured value is
less than the measured value under sunlight.
Turn the ignition switch to “ON” position.
Measure the voltage to the sun sensor from FATC connector. (approx. 2.5 V under sunlight
and 4.8 V under shade.)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller. 1.

2) Active Incar/Humidity Sensor (AIH Sensor)
The AIH sensor is installed at the driver side instrument panel undercover. It is a sensor that
detects interior temperature and humidity.
(1) Location
(2) Functions
Interior temperature sensor
▶
This sensor is a negative temperature coefficient (NTC) thermistor and detects the interio
r
temperature with air coming from senor hole and then sends the voltage value according to the
changed resistance to FATC controller.
Humidity sensor
▶
This sensor detects the interior humidity with humidity cell and then sends the voltage value
according to the changed humidity to FATC controller.

(3) Inspection
If the active incar sensor defect code (DTC 1) and the humidity sensor defect code (DTC 10)
are set, check as below:
Air conditioner controller
Air conditioner controller connector (based on wiring) AIH sensor (based on sensor)
Active incar sensor
▶
Remove the integrated AIH sensor and measure the resistance between terminal No. 5 and
6 on the sensor connector. (standard: approx. 25°C, 2.2 kΩ)
If the measured value is out of the specified range, replace the AIH sensor. If the measured
values are within the specified range, check as below.
Turn the ignition switch to ON position and measure the voltage to active incar sensor from
the FATC controller connector. (standard: approx. 2 V at 25°C)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller.

Humidity sensor ▶
Apply 5 V to terminal No. 1 and 3 on the humidity sensor connector.
Connect the positive (+) probe of a tester on No. 2 terminal and the negative (-) probe on
No. 3 terminal, and measure the output voltage while the voltage is applied.
(output voltage: approx. 0.8 ~ 3.4 V)
Check whether the output voltage is changed when blowing into the inlet of the sensor. I
f
there is a voltage change, the sensor is in normal condition. However, if the voltage is not
changed, replace the humidity sensor.
In addition, if the output voltage is extremely high or low even in the specified range, replace
the humidity sensor. 1.
