Repair Procedures: Inspection
WARNING: This page is about a different car, the 2023 Hyundai Palisade. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Before measuring the pressure of the refrigerant line, check whether the refrigerant amount is charged in accordance with the specified charging amount. (Refer to Heating, Ventilation, Air Conditioning - "SPECIFICATIONS ")
- Turn the ignition switch OFF.
- Install the refrigerant recovery/recycling/charging system. (Refer to Air Conditioning System - "REPAIR PROCEDURES ")
- Turn ON the ignition switch, put into operation the air conditioner.
- 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
- Measure the sensor output voltage between terminal "1" and "2".
Pin No Function 1 Ground 2 Voltage 3 Power (+5V) - If the reference voltage value and the sensor output voltage value are close to each other, the air conditioner pressure transducer is normal.
- If 0 V is output or the reference voltage value and sensor output voltage value are not close to each other, replace the air conditioner pressure transducer.
Information
- Check if the output voltage changes when the high pressure value of the refrigerant line changes.
