Hyundai i-30: 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 OFF.
|
2. |
Disconnect the evaporator temperature sensor connector.
|
3. |
Measure the resistance between terminal "+" and "-" of the evaporator
temperature sensor.

1. |
The heating, ventilation and air conditioning can be quickly diagnosed
failed parts with vehicle diagnostic system (GDS).
※ The diagnostic system (GDS) provides the following information.
(1) Self diagnosis : Checking the failure code (DTC) and display.
(2) Current data : Checking the system input/output data state.
(3) Actuation test : Checking the system operation condition.
(4) Additional function : Other controlling such as he system option
and zero point adjustment.
|
2. |
Select the 'Car model' and the system to be checked in order to check
the vehicle with the tester.
|
3. |
Select the 'Current data' menu to search the current state of the input
/ output data.
The input / output data for the sensors corresponding to the Evaporator
Temperature Sensor can be checked.
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Remove the heater and blower unit from the crash pad after loosening
the mounting nuts.
(Refer to Heater - "Heater Unit")
|
3. |
Remove the evaporator core cover (A) after loosening the mounting screws.
|
4. |
Pull out the evaporator core (A) from the heater unit.
|
5. |
Remove the evaporator temperature sensor (A) from the evaporator core.
|
6. |
To install, reverse the removal procedure.
