REFRIGERANT PRESSURE SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER]

id0740a1817400

1.  Install the manifold gauge.

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

3.  Measure the terminal voltage of the PCM, 3G, 3F or 3H.

4.  Verify that below graph as measure the terminal voltage 3F.

5.  Follow the PCM inspection when measure the other terminal voltage 3G or 3H (See PCM INSPECTION [MZ-CD 1.4 DI Turbo].) (See PCM INSPECTION [MZ-CD 1.6 (Y6)].)

•  Terminal 3G: 1.0 V or less

•  Terminal 3H: 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.
