Hyundai Tucson: Electric WGT Control Actuator- Installation

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Control - Fuel System / Electric WGT Control Actuator / Electric WGT Control Actuator- Installation

WARNING

  • When replacing the Electric WGT Control Actuator, perform the rod adjustment procedure.
  • When install the electric WGT control actuator, do not reuse a C-Ring.
  1. Install in the reverse order of removal.

Adjustment

Rod Adjustment Procedure Flowchart

  1. Check that the waste gate turbo charger is coolenough to work.

WARNING

  • Use an electric fan to cool down fast.
  • The cooling part (A) and the wind direction (B) areas follows.

  1. Turn the ignition switch to OFF position.
  2. Connect the diagnostic tool to DLC connector (16pin) under the driver side instrument panel.
  3. Turn the ignition switch ON.

WARNING

Do not start the engine.

  1. Select VIN or Vehicle on the initial screen.
  2.  Enter "Engine Control" menu after slelecting vehicleinformation (Vehicle model. Model year. Engine type)or entering the VIN number.
  3. Select the "Current Data".
  4. Without starting the engine, repeatedly turn theignition ON for 5 seconds and OFF for 5 seconds.and then check the "Adaptation value for lowmechanical stop of EWGA" on the diagnostic tool.

    Repeat this step until the amount of difference in theadaptation value from the previous cycle is below 0.05 V.

WARNING

Do not start the engine. This is a crucial step toread the correct adaptation value.

  1. Check that "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage value.

Voltage : 3.5 - 3.7V

  1. If the measured voltage value is not within the specified voltage value, ad just the EWGA rodlength. Otherwise, no further procedure is required.

(1) Loosen the rod end lock nut (B) and remove the C-ring (A).

(2) Adjust the rod end part (C) by rotating it clockwise (D) or counterclockwise (E) to satisfy the specification.

  1. Install the rod end (B) to the turbocharger lever (A) temporarily. Do not tighten the rod end lock nut (C) and C-ring (D).

  1. Check the "Adaptation value for the lower mechanical stop of EWGA" after selecting "Current Data" menu. Turn the ignition switch ON/OFF repeatedly until the changing value of the "Adaptation value for the lower mechanical stop of EWGA" is within 0.05V.

WARNING

Turn the ignition switch ON/OFF. But hold 5 seconds at each IG ON or OFF state.

  1. If the measured voltage value is not within the specified voltage value, repeat procedures 9 - 1 2 until the voltage value is within the specified voltage value.
  2. If it is within the specified voltage value, install the rod end to the turbocharger lever.

(1) Install the rod end (B) to the turbocharger lever (A) temporarily.

(2) Fix the C-ring (C).

  1. Install the 0.6mm filler gauge between EWGA lever (A) and rod end (B).

  1. Tighten the lock nut (A).
