8. AIR CONDITIONER MODULE SENSORS AND
ACTUATORS
1) Water Temperature Sensor
(1) Inspection
If the water temperature sensor defect code (DTC 3) is set, check as below.
-
Remove the water 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 low, replace the sensor.
-
If the measured value is out of the specified range, replace the water temperature sensor.
If the measured value is within the specified range, check as below.
-
Turn the ignition switch to ON position and measure the voltage to water temperature
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.
