Kia Rio: Air Conditioning System / Evaporator Temperature Sensor
Description and operation
The evaporator temperature sensor will detect the evaporator core temperature
and interrupt compressor relay power in order to prevent evaporator freezing by
excessive cooling.
Repair procedures
1. |
Turn the ignition switch OFF.
|
2. |
Disconnect the evaporator temperature sensor connector.
|
3. |
Measure resistance between terminal “+” and “-” of evaporator temperature
sensor.
|
4. |
Connect the evaporator temperature sensor connector.
|
5. |
Run the engine and turn the A/C switch ON, then measure the voltage between
the terminals of harness connector.
