Hyundai Elantra: 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 from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC). Electrical resistivity of NTC will increase with decreasing temperature and decrease with increasing temperature.
Repair procedures
1. | Turn the ignition switch ON. |
2. | Turn the A/C switch ON. |
3. | Measure the resistance between terminal "+" and "-" of the evaporator temperature sensor.
