PROCEDURE


  1. CHECK DTC OUTPUT (IN ADDITION TO DTC P011C)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

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


      Powertrain > Engine > Trouble Codes

    4. Read the DTCs.

      Result
      Proceed to
      DTC P011C is output
      DTC P011C and other DTCs are output

      Tech Tips

      If any DTCs other than P011C are output, troubleshoot those DTCs first.

  2. READ VALUE USING GTS (ENGINE COOLANT TEMPERATURE)


    1. Allow the engine to soak for 1 to 2 hours.

      Tech Tips


      • It is not necessary to allow the engine to soak if the engine is cold.

      • The engine cools faster if the hood is opened.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON and turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List / Coolant temp.


      Powertrain > Engine > Data List
      Tester Display
      Coolant Temp

    5. Read the value.

      OK
      The difference between the displayed value and outside air temperature is below 5°C (9°F).

      Note

      If the difference between "Coolant Temp" and the outside air temperature is 5°C (9°F) or higher, the heat from the engine affects the intake air temperature sensor, causing an incorrect value to be displayed. In this case, allow the engine to soak again.

  3. READ VALUE USING GTS (INTAKE AIR TEMPERATURE)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine / Data List / Intake Air.


      Powertrain > Engine > Data List
      Tester Display
      Intake Air

    4. Read the value.

      OK
      The difference between the displayed value and outside air temperature is below 15°C (27°F).

  11. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Allow the engine to soak for 1 to 2 hours.

      Tech Tips


      • It is not necessary to allow the engine to soak if the engine is cold.

      • The engine cools faster if the hood is opened.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON and turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List / Coolant temp.


      Powertrain > Engine > Data List
      Tester Display
      Coolant Temp

    5. Read the value.

      Note

      If the difference between "Coolant Temp" and the outside air temperature is 5°C (9°F) or higher, the heat from the engine affects the intake air temperature sensor, causing an incorrect value to be displayed. In this case, allow the engine to soak again.

    6. Enter the following menus: Powertrain / Engine / Data List / Intake Air and Intake Air Temp (Turbo).


      Powertrain > Engine > Data List
      Tester Display
