  1. CHECK GROUND CONNECTION
    1. Turn ignition switch OFF.
    2. Check ground connection E9. Refer to Ground Inspection in "CIRCUIT INSPECTION ".

    Is the inspection result normal? 

    YES: GO TO 2.

    NO: Repair or replace ground connection.

  2. CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
    1. Disconnect A/F sensor 1 harness connector.
    2. Turn ignition switch ON.
    3. Check the voltage between A/F sensor 1 harness connector and ground.

    • IPDM E/R harness connector F10
    • 15 A fuse (No. 37)
    • Harness for open or short between A/F sensor 1 and fuse

    : Repair or replace harness or connectors.

  4. CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between A/F sensor 1 harness connector and ECM harness connector.

    5. Also check harness for short to power.

    Is the inspection result normal? 

    YES: GO TO 5.

    NO: Repair open circuit, short to ground or short to power in harness or connectors.

  5. CHECK INTERMITTENT INCIDENT

    Perform "INTERMITTENT INCIDENT ".

    Is the inspection result normal? 

    YES: GO TO 6.

    NO: Repair or replace malfunctioning part.

  6. REPLACE AIR FUEL RATIO (A/F) SENSOR 1

    Replace malfunctioning air fuel ratio (A/F) sensor 1.

    CAUTION:
    • Discard any A/F sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
    • Before installing new A/F sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner [commercial service tool (J-43897-18 or J-43897-12)] and approved anti-seize lubricant (commercial service tool).
