REFRIGERANT PRESSURE SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER]

id0740a1817400

European (L.H.D. U.K.) specs. (Except MZ-CD 1.6 (Y6) (EURO5 emission level))

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.

―  2C, 2N 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. (See CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER].)

•  Terminal 2N: 1.0 V or less

•  Terminal 2C: 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.

European (L.H.D. U.K.) specs. (MZ-CD 1.6 (Y6) (EURO5 emission level))

1.  Install the manifold gauge.

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

3.  Measure the terminal voltage of the PCM.

―  1N, 1O and 1P

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

5.  Follow the PCM inspection when measure the other terminal voltage. (See PCM INSPECTION [MZ-CD 1.6 (Y6) (EURO5 emission level)].)

•  Terminal 1N: 1.0 V or less

•  Terminal 1P: 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.
