Component Inspection

  1. INSPECTION START 

    Do you have CONSULT?

    Do you have CONSULT? 

    YES: GO TO 2.

    NO: GO TO  3.

  2. CHECK HEATED OXYGEN SENSOR 2 

    With CONSULT

    1. Turn ignition switch ON and select "DATA MONITOR" mode of "ENGINE" using CONSULT.
    2. Start engine and warm it up to normal operating temperature.
    3. Turn ignition switch OFF and wait at least 10 seconds.
    4. Start engine and keep the engine speed between 3, 500 and 4, 000 RPM for at least 1 minute under no load.
    5. Let engine idle for 1 minute.
    6. Select "FUEL INJECTION" in "ACTIVE TEST" mode of "ENGINE" using CONSULT, and select "HO2S2 (B1)" as the monitor item with CONSULT.
    7. Check "HO2S2 (B1)" at idle speed when adjusting "FUEL INJECTION" to ± 25%.

      "HO2S2 (B1)" should be above 0.68 V at least once when the "FUEL INJECTION" is + 25%. 

      "HO2S2 (B1)" should be below 0.18 V at least once when the "FUEL INJECTION" is - 25%. 

      Is the inspection result normal? 

      YES: INSPECTION END

      NO: GO TO  6.

  3. CHECK HEATED OXYGEN SENSOR 2-I 

    Without CONSULT

    1. Start engine and warm it up to normal operating temperature.
    2. Turn ignition switch OFF and wait at least 10 seconds.
    3. Start engine and keep the engine speed between 3, 500 and 4, 000 RPM for at least 1 minute under no load.
    4. Let engine idle for 1 minute.
    5. Check the voltage between ECM harness connector and ground as per the following condition.
      ECM Condition Voltage
      Connector + -
      Terminal
      F25 29 33 Revving up to 4, 000 RPM under no load at least 10 times The voltage should be above 0.68 V at least once during this procedure.
      The voltage should be below 0.18 V at least once during this procedure.

      Is the inspection result normal? 

      YES: INSPECTION END

      NO: GO TO 4.

  4. CHECK HEATED OXYGEN SENSOR 2-II 

    Check the voltage between ECM harness connector and ground as per the following condition.

    ECM Condition Voltage
    Connector + -
    Terminal
    F25 29 33 Keeping engine speed at idle for 10 minutes The voltage should be above 0.68 V at least once during this procedure.
    The voltage should be below 0.18 V at least once during this procedure.

    Is the inspection result normal? 

    YES: INSPECTION END

    NO: GO TO 5.

  5. CHECK HEATED OXYGEN SENSOR 2-III 

    Check the voltage between ECM harness connector and ground as per the following condition.

    ECM Condition Voltage
    Connector + -
    Terminal
    F25 29 33 Coasting from 80 km/h (50 MPH) in D position (CVT), 4th gear position (M/T) The voltage should be above 0.68 V at least once during this procedure.
    The voltage should be below 0.18 V at least once during this procedure.

    Is the inspection result normal? 

    YES: INSPECTION END

    NO: GO TO 6.

  6. REPLACE HEATED OXYGEN SENSOR 2 

    Replace heated oxygen sensor 2. Refer to "EXPLODED VIEW ".

    CAUTION:
    • Discard any 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 sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner [commercial service tool (J-43897-18 or J43897-12)] and approved Anti-seize Lubricant (commercial service tool).
