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

      Refer to INITIALIZATION [11/2018 - 10/2019] , or refer to INITIALIZATION [10/2019 - 08/2020]

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    REPAIR OR REPLACE INTAKE SYSTEM 

    Result: 

    OK 

    See step  4

  4. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE EGR STEP POSITION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher.

      HINT: 

      The A/C switch and all accessories should be off.

    5. Enter the following menus: Powertrain / Engine / Active Test / Control the EGR Step Position / Data List / Engine Speed, Intake Manifold Absolute Pressure and Coolant Temperature.

      Powertrain > Engine > Active Test 

      Active Test Display
      Control the EGR Step Position
      Data List Display
      Engine Speed
      Intake Manifold Absolute Pressure
      Coolant Temperature
    6. Check the engine idling condition and Intake Manifold Absolute Pressure values in the Data List while performing the Active Test.
      NOTE:
      • Do not leave the EGR valve open for 10 seconds or more during the Active Test.
      • Be sure to return the EGR valve to step 0 when the Active Test is completed.
      • Do not open the EGR valve 30 steps or more during the Active Test.

      OK

      The value of Intake Manifold Absolute Pressure and Engine Speed change in response to EGR step position.

      Standard

      - Control the EGR Step Position (Active Test)
      0 Steps 0 to 30 Steps
      Idling condition Steady idling Idling changes from steady to rough idling or engine stalls
      Intake Manifold Absolute Pressure
      (Data List)      		 Intake Manifold Absolute Pressure value is 20 to 40 kPa(abs)
      (2.9 to 5.8 psi(abs))
      (EGR valve is fully closed)      		 Intake Manifold Absolute Pressure value is at least +10 kPa (1.45 psi) higher than when EGR valve is fully closed

      HINT: 

      During Active Test, if the idling condition does not change in response to EGR step position, then there is probably a malfunction in the EGR valve.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK
