Description
It is mounted on the evaporator to prevent freezing by sensing the temperature of the evaporator core. A NTC thermistor is installed inside the sensor, so when the temperature decreases, the resistance value increases, and when the temperature increases, the resistance value decreases.Removal
• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be observed and aware of "High Voltage System General Safety Information and Caution". If not, it may cause serious accidents such as electric shock or short circuit.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
1.Remove the evaporator core.(Refer to Heater - "Evaporator Core")
2.Remove the evaporator temperature sensor (A).

1.Install in reverse order of removal.
Inspection
1.Turn IG ON.
2.Turn on the air conditioner switch.
3.Measure the resistance of the ( + ) and ( - ) terminals after connecting the multi-tester to the evaporator temperature sensor.
