Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. READ VALUE USING GTS (INTAKE AIR TEMP (TURBO))


    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 Temp (Turbo).


      Powertrain > Engine and ECT > Data List
      Tester Display
      Intake Air Temp (Turbo)

    4. Read the value.

      OK
      -40°C (-40°F) to 120°C (248°F).

  2. CHECK HARNESS AND CONNECTOR (INTAKE AIR TEMPERATURE SENSOR - ECM)


    1. Disconnect the intake air temperature sensor connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B115-1 (THA) - B112-79 (THIA) Always Below 1 Ω
      B115-2 (E2) - B112-89 (ETHI) Always Below 1 Ω
      B115-1 (THA) or B112-79 (THIA) - Body ground Always 10 kΩ or higher

  4. CHECK INTAKE SYSTEM


    1. Start the engine.

    2. Check air duct between intake silencer, mass air flow meter sub-assembly and turbocharger for leaks.

    3. Check air duct between turbocharger and intake manifold for leaks.

      Tech Tips


      • Oily patches are signs of leaks.

      • Check whether sealing rings on charge air hoses are rolled back or missing.

      OK
      No leakage.
