Hyundai Sonata: Air Conditioning System / A/C Pressure Transducer Repair procedures
| Inspection |
| 1. |
Measure the pressure of high pressure line by measuring voltage output between terminal "1" and "2".
|
| 2. |
Inspect the voltage value whether it is sufficient to be regular value or not.
|
| 3. |
If the measured voltage value is not wihtin specification, replace the A/C pressure transducer. |
| Diagnosis With GDS |
| 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 A/C Pressure Transducer can be checked.
|
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal. |
| 2. |
Recover the refrigerant with a recovery/charging station. |
| 3. |
Disconnect the A/C pressure transducer connector (A).
|
| 4. |
Remove the A/C pressure transducer (A).
|
| 5. |
Install in the reverse order of removal.
