Refrigerant Pressure Sensor Inspection - Full-Auto Air Conditioner

REFRIGERANT PRESSURE SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER]

1. Install the manifold gauge.

2. Verify the high-pressure side reading of the manifold gauge.

3. Measure the terminal voltage of the climate control unit.

- 1C, 1J and 1N

4. Verify that below graph as measure the terminal voltage 1N.

5. Follow the climate control unit inspection when measure the other terminal voltage. Climate Control Unit Inspection - Full-Auto Air Conditioner

- Terminal 1C: 1.0 V or less
- Terminal 1J: Approx. 5 V (Ignition switch on)

- If the each voltage is not normal, inspect the related wiring harness.

- If there is any malfunction, replace the related wiring harness.
- If wiring harness is normal, replace the refrigerant pressure sensor.
