  8. Start the engine and wait 2 minutes [D].

  9. Warm up the engine until the engine coolant temperature is 73°C (163°F) or higher [E].

  10. Idle the engine for 1 minute [F].

  11. With the engine running, accelerate the vehicle to 80 km/h (50 mph) and stop the vehicle [G].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    Tech Tips

    If the engine stops, further depress the accelerator pedal to restart the engine.

  12. With the engine running, drive the vehicle at 56 to 80 km/h (35 to 50 mph) for 5 minutes or more [H].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    Tech Tips

    If the engine stops, further depress the accelerator pedal to restart the engine.

  13. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [I].

  14. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  15. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  16. Input the DTC: P0607, P0136, P0137 or P0138.

  17. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [E] through [I] again.

CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK FOR ANY OTHER DTCS OUTPUT


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    5. Read the DTCs.

  2. INSPECT DTC (P0136, P0137 OR P0138)


    1. Refer to the P0136, P0137 or P0138 flowchart.

      Tech Tips


      • If P0136 is output, troubleshoot for that DTC first Click here. Then proceed to "Inspect ECM".

      • If P0137 is output, troubleshoot for that DTC first Click here. Then proceed to "Inspect ECM".

      • If P0138 is output, troubleshoot for that DTC first Click here. Then proceed to "Inspect ECM".

      • If DTC P0607 and P0136, P0137 or P0138 are output, the output voltage of the heated oxygen sensor may remain close to 0 V or become high (around 1 V or higher).

  3. CHECK FOR EXHAUST GAS LEAK


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG) and turn the GTS on.

    3. Put the engine in inspection mode (maintenance mode).

    4. Start the engine.

    5. Allow the engine to idle and then rev the engine.

    6. Check for exhaust gas leaks around the heated oxygen sensor.

      If any exhaust gas leaks are present, repair them and proceed to "Perform Confirmation Driving Pattern". If no exhaust gas leaks are present, proceed to "Perform Confirmation Driving Pattern".

      Tech Tips


      • If no exhaust gas leaks are present, there may be a malfunction in the heated oxygen sensor circuit.

      • If any exhaust gas leaks are present around the heated oxygen sensor, noise appears in the output voltage of the heated oxygen sensor.

      • Perform "Inspection After Repair" after repairing or replacing the exhaust system.
