MONITOR DESCRIPTION

These DTCs are stored when there is an open or short in the air fuel ratio sensor (sensor 2) circuit, or the air fuel ratio sensor (sensor 2) output value is abnormal. The voltage of the air fuel ratio sensor (sensor 2) is monitored while the power switch is on (IG) or the impedance is checked while engine running. If the voltage of the air fuel ratio sensor (sensor 2) is outside the normal range or the impedance is outside the normal range, the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the power switch off and wait for at least 30 seconds.

  6. Turn the power switch on (IG).

  7. Turn the GTS on.

  8. Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).

  9. Start the engine and wait 5 minutes or more.

  10. Enter the following menus: Powertrain / Engine / Trouble Codes.

  11. 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.

  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  13. Input the DTC: P22AB11, P22AB12, P22AB13, P22AB16, P22AB17, P22B211, P22B212, P22B811, P22B812, P22B813, P22B816, P22B817, P22BF11 or P22BF12.

  14. 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

    Tech Tips


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

    • If the judgment result shows ABNORMAL, the system is malfunctioning.

    • If the judgment result shows INCOMPLETE, idle the engine for 5 minutes and check the DTC judgment result again.

CAUTION / NOTICE / HINT

Note


  • Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

    Click here

    (Select Powertrain in Health Check and then check the time stamp data.)

    Click here

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

  • Inspect the fuses for circuits related to this system before performing the following procedure.

Tech Tips


  • Bank 1 refers to the bank that includes the No. 1 cylinder*.

    *: The No. 1 cylinder is the cylinder which is farthest from the transmission.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.

  • Sensor 1 refers to the sensor closest to the engine assembly.

  • Sensor 2 refers to the sensor farthest away from the engine assembly.

  • Refer to "Data List / Active Test" [A/F (O2) Sensor Current B1S2 or A/F (O2) Sensor Current B2S2].

  • 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 TERMINAL VOLTAGE (AIR FUEL RATIO SENSOR (SENSOR 2) VOLTAGE)

    Tech Tips

    Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.


    1. Disconnect the air fuel ratio sensor (sensor 2) connector.

    2. Turn the power switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      G28-3 (A1B+) - G28-4 (A1B-) Power switch on (IG) 0.2 to 0.6 V
      G29-3 (A2B+) - Body ground Power switch on (IG) 3.4 to 3.6 V
      G29-4 (A2B-) - Body ground Power switch on (IG) 3.0 to 3.2 V
      G29-3 (A2B+) - G29-4 (A2B-) Power switch on (IG) 0.2 to 0.6 V
