REFRIGERANT PRESSURE SENSOR INSPECTION

id074000817400

1. Install the manifold gauge.

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

3. Follow the PCM inspection when measure the other terminal voltage. (See PCM INSPECTION [MZI-3.7].)

  • Terminal GND: 1.0 V or less
  • Terminal +5: Approx. 5 V (Ignition switch on)
  • Terminal OUTPUT: Verify that below graph as measure the terminal
    ― 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.
