Hyundai Venue: Air Conditioning System / A/C Pressure Transducer. Repair procedures
• |
Before measuring the pressure of the refriferant line, check
whether the refrigerant amount is charged in accordance with
the specified charging amount.
(Refer to Heating, Ventilation, Air Conditioning - "Specifications")
|
|
1. |
Turn the ignition switch OFF.
|
2. |
Install the refrigerant recovery/recycling/charging system.
(Refer to Air Conditioning System - "Repair procedures")
|
3. |
Turn ON the ignition switch, put into operation the air conditioner.
|
4. |
Calculate the reference voltage of the Recovery/Recycle/Recharge machine
high pressure value using the formula below.
Reference voltage (V) = 0.0088 * pressure(psi) + 0.37
|
|
5. |
Measure the sensor output voltage between terminal "1" and "2".

6. |
If the reference voltage value and the sensor output voltage value are
close to each other, the air conditioner pressure transducer is normal.
|
7. |
If 0V is output or the reference voltage value and sensor output voltage
value are not close to each other, replace the air conditioner pressure
transducer.
•
|
Check if the output voltage changes when the high pressure
value of the refrigerant line changes.
|
|
|
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.
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Recover the refrigerant with a recovery / charging station.
|
3. |
Press the lock pin and separate the A/C pressure transducer connector
(A).
|
4. |
Remove the A/C pressure transducer (A).
Tightening torque :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
|
•
|
Be careful not to bend the liquid & suction pipe.
|
|
|
5. |
To install, reverse the removal procedure.
•
|
When installing, replace it with a new O-ring.

This gauge indicates the approximate amount of fuel remaining in the fuel tank.
Information
The fuel tank capacity is given in chapter 2.
The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is nearly empty.
On inclines or curves, the fuel gauge pointer may fluctuate or the low
fuel warning light may come on earlier than usual due to the movement of fuel
in the tank.
