EWG Motor Inspection Procedure: 1. Turn ignition switch OFF. 2. Disconnect the EWGA connector (A). A TSB #: 22-EM-004H Page 3 of 8 SUBJECT: SUBJECT: THETA-II 2.0T TURBOCHARGER EWGA DIAGNOSIS AND SERVICE PART REPLACEMENT GUIDELINES 3. AND SERVICEpreventing PART REPLACEMENT GUIDELINES Check that there are no obstructions EWGA motor movement. 4. Measure resistance between the (+) and (-) terminals of the motor and check that it is within specification. 5. If the EWGA motor resistance is not within specification, replace the EWGA with the service procedure on page 7. EWGA Position Sensor Inspection Procedure: 1. Prepare the GDS to begin the EWGA Position Sensor inspection and adjustment. a) Ensure ignition switch is OFF. b) Connect the 16-pin DLC cable from the VCI into the vehicle’s 16-pin connector under the driver side instrument panel. c) Turn on the VCI and diagnostic terminal with the ignition key in the ON position. NOTICE Do NOT start the engine. The turbocharger and its actuation mechanism should be cold to allow proper inspection and adjustment procedures. d) Choose VIN or Vehicle on the initial screen. e) Enter vehicle information by pressing the VIN Auto Detect button; entering the VIN or selecting the vehicle model, model year, engine type, and Engine Control as the system, and then click OK. 2. Choose Current Data, and then select Battery Voltage after Ignition Key and Voltage Value for Boost Pressure Actuator Position Control. TSB #: 22-EM-004H Page 4 of 8 SUBJECT: SUBJECT: 3. THETA-II 2.0T TURBOCHARGER EWGA DIAGNOSIS AND SERVICE PART REPLACEMENT GUIDELINES Choose the Graph and check the voltage. ➢ Turn ignition ON/OFF three times, and then check the Max voltage value just as ignition ON state is about to change to ignition OFF state and vice versa. Refer to specified voltages on the following page. ➢ If the EWGA position sensor is not within specified voltage, perform the following EWGA ADJUSTMENT PROCEDURE, and check that the same fault code is detected again before replacing the EWGA. NOTICE If the EWGA has an internal issue that requires replacement, replace with applicable service part listed in parts information. Do not replace the entire turbocharger assembly. EWGA Adjustment Procedure: 1. Open the hood and securely support it. ! CAUTION B Check that the engine is cool enough to work on. Loosen the turbocharger upper cover bolt (B) and remove cover. 2. Loosen the shaft end lock nut (C) and remove the retaining clip (D). Save the retaining clip for later use. D ! CAUTION C When loosening lock nut (C) securely hold the waste gate arm to prevent shaft bending. TSB #: 22-EM-004H Page 5 of 8 SUBJECT: SUBJECT: 3. THETA-II 2.0T TURBOCHARGER EWGA DIAGNOSIS AND SERVICE PART REPLACEMENT GUIDELINES AND SERVICE PART REPLACEMENT GUIDELINES Adjust the shaft end by rotating it clockwise or counterclockwise in ½ turn increments until voltage is within specification range. Then temporarily install the shaft end and tighten the shaft end lock nut. Check the Voltage Value for Boost Pressure Actuator Position Control by using the inspection procedure with the GDS. The EWGA must be in the fully closed position while applying pressure on the EWGA lever to accurately measure the output voltage while the engine is cold. ➢ If output voltage > Max. specified Voltage: Turn shaft ends clockwise (to shorten the ends) E ➢ If output voltage < Min. specified Voltage: Turn shaft ends counterclockwise (to lengthen the ends). If unable to achieve proper voltage specification when the engine is cold, it may be necessary to rotate both EWGA shaft ends (E) to achieve proper voltage. 4. If the output voltage is not within specification, repeat step 3 in EWGA adjustment procedure until voltage is within specification range. 5. If output voltage is still not within specification after EWGA adjustment, replace EWGA with the service procedure on the following page. If output voltage is within specification, reinstall all the removed parts in reverse order of removal. 6. Start engine and let run for a few minutes while cycling the throttle, then shut off engine. Recheck voltage while applying pressure on the EWGA lever to accurately measure output voltage as indicated in the photo on the right. ! CAUTION Engine components are hot and can cause burns.
