Manual Air Conditioner

REFRIGERANT PRESSURE SENSOR INSPECTION [MANUAL AIR CONDITIONER]

MZR 2.0, MZR 2.5

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.

- 1G,1H and 2J

4. Verify that below graph as measure the terminal voltage 2J.

5. Follow the climate control unit inspection when measure the other terminal voltage. Manual Air Conditioner

- Terminal 1G: 1.0 V or less
- Terminal 1H: 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.





SKYACTIV-G 2.0

1. Install the manifold gauge.

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

3. Measure the terminal voltage of the PCM.

- 2BB, 2AX and 2AJ

4. Verify that below graph as measure the terminal voltage 2AX.

5. Follow the PCM inspection when measure the other terminal voltage. Component Tests and General Diagnostics

- Terminal 2BB: 1.0 V or less
- Terminal 2AJ: 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.
