Diagnosis Procedure

  1. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR FOR WATER 
    1. Turn ignition switch OFF.
    2. Disconnect EVAP control system pressure sensor harness connector.
    3. Check sensor harness connector for water.

      Water should not exist. 

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: Repair or replace harness connector.

  2. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY 
    1. Turn ignition switch ON.
    2. Check the voltage between EVAP control system pressure sensor harness connector and ground.
      + - Voltage (Approx.)
      EVAP control system pressure sensor
      Connector Terminal
      B22 3 Ground 5 V

      Is the inspection result normal? 

      YES: GO TO  4.

      NO: GO TO 3.

  3. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between EVAP control system pressure sensor harness connector and ECM harness connector.
      + - Continuity
      EVAP control system pressure sensor ECM
      Connector Terminal Connector Terminal
      B22 3 F25 23 Existed
    4. Also check harness for short to ground and to power.

      Is the inspection result normal? 

      YES: Perform the trouble diagnosis for power supply circuit.

      NO: Repair or replace error-detected parts

  4. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR GROUND CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between EVAP control system pressure sensor harness connector and ECM harness connector.
      + - Continuity
      EVAP control system pressure sensor ECM
      Connector Terminal Connector Terminal
      B22 1 F25 12 Existed
    4. Also check harness for short to power.

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair or replace error-detected parts.

  5. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR SIGNAL CIRCUIT 
    1. Check the continuity between EVAP control system pressure sensor harness connector and ECM harness connector.
      + - Continuity
      EVAP control system pressure sensor ECM
      Connector Terminal Connector Terminal
      B22 2 F25 15 Existed
    2. Also check harness for short to ground and to power.

      Is the inspection result normal? 

      YES: GO TO 6.

      NO: Repair or replace error-detected parts.

  6. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR 

    Check the EVAP control system pressure sensor. Refer to "COMPONENT INSPECTION ".

    Is the inspection result normal? 

    YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

    NO: Replace EVAP control system pressure sensor. Refer to "2WD: EXPLODED VIEW " (2WD), "AWD: EXPLODED VIEW " (AWD).
