Charge Air Temperature/Intake Air Temperature Correlation (Bank 1)

After the engine is completely warmed up and then allowed to soak for a long time (10 hours or more), the difference in temperature at the intake air temperature sensor and intake air temperature sensor (turbo) after turbocharger after idling for 3 minutes is 15°C (27°F) or higher.

After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).

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 and ECT / Trouble Codes.

      Powertrain > Engine > Trouble Codes

    4. Read the DTCs.

      Proceed to

      DTC P011C is output

      DTC P011C and other DTCs are output
      Tip:

      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.

      Tip:

      • 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 and ECT / 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 and ECT / Data List / Intake Air.

      Powertrain > Engine > Data List

      Tester Display

      Intake Air

    4. Read the value.

      OK
