FUEL INJECTOR ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK INJECTOR ASSEMBLY


    1. Start the engine and drive the vehicle until the engine coolant temperature reaches 60°C (140°F) or higher.

    2. Allow the engine to idle for 1 minute or more.

    3. Connect the GTS to the DLC3.

    4. Turn the GTS on.

    5. Enter the following menus: Powertrain / Engine / Data List / Injection Volume and Injector Feedback Val. #1 to #4.


      Powertrain > Engine > Data List
      Tester Display
      Injection Feedback Val #1
      Injection Feedback Val #2
      Injection Feedback Val #3
      Injection Feedback Val #4
    6. Read the values when the engine is idling.

    7. Check that the "Injector Feedback Val. #1 to #4" values are within the specification.

      Standard
      Tester Display Engine Condition Specified Condition
      Injection Volume Idling

      3 to 10 mm3/st

      Injector Feedback Val. #1

      Injector Feedback Val. #2

      Injector Feedback Val. #3

      Injector Feedback Val. #4

      Idling

      -3.0 to 3.0 mm3/st

      If the result is not as specified, replace the fuel injector assembly.

  2. CHECK INJECTOR COMPENSATION CODE
