Diagnosis Procedure

  1. 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 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.
    VOLTAGE SPECIFICATION

    A/F sensor 1 Ground Voltage
    Connector Terminal
    F27 4 Ground Battery voltage

    Is the inspection result normal? 

    YES: GO TO  4.

    NO: GO TO 3.

  3. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness connectors E6, F123
    • IPDM E/R harness connector E14
    • 15 A fuse (No. 63)
    • 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 or 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.

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

Replace 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).
