Diagnosis Procedure

  1. INSPECTION START

    Confirm the detected malfunction (A or B). Refer to "DTC LOGIC ".

    Which malfunction is detected?

    A: GO TO  3.

    B: GO TO 2.

  2. CHECK INTAKE SYSTEM

    Check the following for connection.

    • Air duct
    • Vacuum hoses
    • Intake air passage between air duct and intake manifold

    Is the inspection result normal?

    YES: GO TO 3.

    NO: Reconnect the parts.

  3. CHECK GROUND CONNECTION
    1. Turn ignition switch OFF.
    2. Check ground connection E21. Refer to Ground Inspection in "CIRCUIT INSPECTION ".

    Is the inspection result normal?

    YES: GO TO 4.

    NO: Repair or replace ground connection.

  4. CHECK MAF SENSOR POWER SUPPLY CIRCUIT
    1. Disconnect mass air flow (MAF) sensor harness connector.
    2. Turn ignition switch ON.
    3. Check the voltage between MAF sensor harness connector and ground.

      E18 5 Ground Battery voltage

    Is the inspection result normal?

    YES: GO TO  6.

    NO: GO TO 5.

  5. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness for open or short between mass air flow sensor and ECM
    • Harness for open or short between mass air flow sensor and IPDM E/R

    Repair open circuit or short to ground or short to power in harness or connectors.

  6. CHECK MAF SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between MAF sensor harness connector and ECM harness connector.

    4. Also check harness for short to ground and short to power.

    Is the inspection result normal?

    YES: GO TO  8.

    NO: GO TO 7.

  7. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness connectors E6, F123
    • Harness for open or short between mass air flow sensor and ECM

      Repair open circuit or short to ground or short to power in harness or connectors.

  8. CHECK MAF SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
    1. Check the continuity between MAF sensor harness connector and ECM harness connector.

      Connector Terminal Connector Terminal
      E18 3 F8 58 Existed
    2. Also check harness for short to ground and short to power.

    Is the inspection result normal?

    YES: GO TO  10.

    NO: GO TO 9.

  9. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness connectors E6, F123
    • Harness for open or short between mass air flow sensor and ECM

      Repair open circuit or short to ground or short to power in harness or connectors.

  10. CHECK INTAKE AIR TEMPERATURE SENSOR

    Refer to "COMPONENT INSPECTION ".

    Is the inspection result normal?

    YES: GO TO 11.

    NO: Replace mass air flow sensor (with intake air temperature sensor).

  11. CHECK MASS AIR FLOW SENSOR

    Refer to "COMPONENT INSPECTION ".

    Is the inspection result normal?

    YES: GO TO 12.

    NO: Replace mass air flow sensor.

  12. CHECK INTERMITTENT INCIDENT

    Refer to "INTERMITTENT INCIDENT ".
