Diagnosis Procedure

  1. CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY 
    1. Turn ignition OFF.
    2. Disconnect refrigerant pressure sensor harness connector.
    3. Turn ignition switch ON.
    4. Check the voltage between refrigerant pressure sensor harness connector and ground.
      + - Voltage (Approx.)
      Refrigerant pressure sensor
      Connector Terminal
      E49 3 Ground 5 V

      Is the inspection result normal? 

      YES: GO TO  3.

      NO: GO TO 2.

  2. CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
      + - Continuity
      Refrigerant pressure sensor ECM
      Connector Terminal Connector Terminal
      E49 3 F25 23 Existed
    4. Also check harness for short to ground.

      Is the inspection result normal? 

      YES: Perform the trouble diagnosis for power supply circuit.

      NO: Repair or replace error-detected parts.

  3. CHECK REFRIGERANT PRESSURE SENSOR GROUND 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
      + - Continuity
      Refrigerant pressure sensor ECM
      Connector Terminal Connector Terminal
      E49 1 F25 12 Existed
    4. Also check harness for short to power.

      Is the inspection result normal? 

      YES: GO TO 4.

      NO: Repair or replace error-detected parts.

  4. CHECK REFRIGERANT PRESSURE SENSOR INPUT SIGNAL CIRCUIT 
    1. Check the continuity between ECM harness connector and refrigerant pressure sensor harness connector.
      + - Continuity
      Refrigerant pressure sensor ECM
      Connector Terminal Connector Terminal
      E49 2 F25 19 Existed
    2. Also check harness for short to ground and to power.

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair or replace error-detected parts.

  5. CHECK INTERMITTENT INCIDENT. 

    Perform "INTERMITTENT INCIDENT ".

    Is the inspection result normal? 

    YES: Replace refrigerant pressure sensor. Refer to "EXPLODED VIEW ".

    NO: Repair or replace error-detected parts.
