Refrigerant Pressure Sensor Inspection [Full-Auto Air Conditioner]
- Install the manifold gauge.
- Verify the high-pressure side reading of the manifold gauge.
- Follow the climate control unit inspection when measure the other terminal voltage. (See CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER] .)
- Terminal 1V: 1.0 V or less
- Terminal 2L: Approx. 5 V (Ignition switch on)
- Terminal 2I: Verify that below graph as measure the terminal voltage
- 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.
