Repair Procedures: Removal

  1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.
  2. Remove the engine cover.

    (Refer to Engine and Transaxle Assembly - "ENGINE COVER ")

  3. Remove the air cleaner assembly.

    (Refer to Intake and Exhaust System - "AIR CLEANER ")

  4. Remove the front muffler.

    (Refer to Intake and Exhaust System - "MUFFLER ")

  5. Remove the intercooler inlet hoses & pipe (A).

    Tightening torque 

    Bolt: 19.6 - 26.4 N.m (2.0 - 2.7 kgf.m, 14.4 - 19.5 lb-ft)

    Clamp: 4.9 - 6.8 N.m (0.5 - 0.7 kgf.m, 3.6 - 5.0 lb-ft)

    CAUTION:
    • When carrying the turbo charger, do not hold the rod of the turbo charge to prevent bending the rod.
  1. Check that the waste gate turbo charger is cool enough to work.
  2. Turn the ignition switch to OFF position.
  3. Connect the diagnostic tool to DLC connector (16 pin) under the driver side instrument panel.
  4. Turn the ignition switch ON position.
    CAUTION:
    • Do not start the engine.
  5. Select VIN or Vehicle on the initial screen.
  6. Enter "Engine Control" menu after selecting vehicle information (Vehicle model, Model year, Engine type) or entering the VIN number.
  7. Check "Adoption value for the lower mechanical stop of EWGA" after selecting "Current Data" menu.

    Specified voltage value:  4.2 ± 0.1V

  8. If the voltage value measured is not within the specified voltage value, adjust the EWGA rod length. But, if no, no further procedure is required.
    1. Loosen the rod end lock nut (A) and remove the C-ring (B).
    2. Adjust the rod end part (C) by rotating it clockwise (D) or counterclockwise (E) to satisfy the specification.
      • If output voltage > 4.3V

        : Turn it clockwise (D)

      • If output voltage < 4.1V

        : Turn it counterclockwise (E)

      Turning angle Changing level of the adaption value (V)
      0.5 turn (180°) 0.15 - 0.20
      1 turn (360°) 0.30 - 0.40
  9. Install the rod end part (C) to the turbo charger lever (D) temporarily. Don't tighten the rod end lock nut (A).
  10. Turn the ignition switch ON/OFF 5 times. But hold 5 seconds at each IG ON or OFF state.
    NOTE:
    • Turn the ignition switch ON/OFF repeatedly until the changing value of "Adoption value for the lower mechanical stop of EWGA" is within 0.05V.

    When turning the ignition switch ON or OFF once, maximum changing level of the adoption value: Max. ± 0.05V
  11. If the voltage value measured is not within the specified voltage value, repeat 8 - 10 procedures until the voltage value is within the specified voltage value.

    Specified voltage value:  4.1 - 4.3V

  12. Check that "Adoption value for the lower mechanical stop of EWGA" is within the specified voltage value.
  13. If it is within the specified voltage value, install the turbo charger lever (D) and the rod end part (C).
    CAUTION:
    • Be careful not to remove the washer (E).
  14. Tighten the rod end locking nut (A). The turbo charger lever (D) side and the rod end part (C) side should be parallel at this time.
  15. Install the C-ring (B).
