6. AIR CONDITIONER MODULE SENSORS AND ACTUATORS
1) Duct Temperature Sensor
The duct temperature sensor is installed on the top of heater unit. It detects the inside
temperature of duct and transmits the voltage value that is changed according to resistance
value (NTC) to FATC controller.
(1) Inspection
If the duct temperature sensor defect code (DTC 3) is set, check as below.
▶
Remove the duct temperature sensor and measure the resistance between terminals on the
sensor connector. (standard: approx. 25°C, 2.2 kΩ) In addition, if the resistance is
extremely high or, replace the sensor.
If the measured value is out of the specified range, replace the duct temperature sensor. I
f
the measured value is within the specified range, check as below.
Turn the ignition switch to ON position and measure the voltage to duct temperature senso
r
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.
