Repair Procedures: Inspection
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
- 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".SENSOR OUTPUT VOLTAGE SPECIFICATION
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 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.
