Campaign SA078 - EWGA Inspection/Adjustment

GROUP Engine

NUMBER 099

MODEL 2011MY Optima (TF)

DATE April 2011

SUBJECT:
SERVICE ACTION: OPTIMA (TF) EWGA INSPECTION AND ADJUSTMENT (SA078)

On some Optima vehicles with 2.0 T-GDI engine produced from December 24, 2010 to March 18, 2011, the engine warning light may illuminate with DTC P2562. Inspect the voltage value for boost pressure actuator position control by using GDS. If the voltage is not within specified value (3.85-4.45 V), adjust the EWGA rod length following the Service Procedure outlined in this bulletin. To ensure maximum customer satisfaction Kia is requesting the completion of this Service Action on all affected 2011 MY Optima vehicles prior to delivery.





DTC P2562: Turbocharger Boost Control Position Sensor "A" Circuit

EWGA: Electric Waste Gate Actuator

*NOTICE:
A Service Action is a repair program without customer notification that is performed during the warranty period. Any dealer requesting to perform this repair outside the warranty period will require DPSM approval.

Repair status for a VIN is provided on WebDCS (Service > Warranty Coverage > Warranty Coverage Inquiry > Campaign Information). Not completed Recall/Service Action reports are available on WebDCS (Customer Affairs > Not Completed Recall > Recall VIN > Select Report), which includes a list of affected vehicles.

This issue number is SA078.

Inspection Procedure:

1. Turn the ignition switch to OFF position.





Connect the 16-pin DLC cable from the VCI into the vehicle's 16-pin connector under the driver side instrument panel.

Turn on the VCI and diagnostic terminal with the ignition key in the ON position.

NOTE:
Do NOT start the engine.

Choose VIN or Vehicle on the initial screen.





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 the Current Data, and select the Battery Voltage after Ignition Key and the Voltage Value for Boost Pressure Actuator Position Control.





3. 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.

Specified voltage value : 3.85 - 4.45 V

If the voltage value measured is not within the specified voltage value adjust the EWGA rod length following the EWGA ADJUSTMENT PROCEDURE below.

If voltage value is within specification no further action is necessary.

EWGA Adjustment Procedure:

1. Open the hood and securely support it.

CAUTION
Check that engine is cool enough to work on.





Loosen the turbocharger upper cover bolt (A) and remove cover.





2. Loosen the rod end lock nut (B) and remove the retaining clip (C).





3. Adjust the rod end by rotating it clockwise or counterclockwise until voltage is within specification range. Then temporarily install the rod end and tighten the rod end lock nut. Check the Voltage Value for Boost Pressure Actuator Position Control by using GDS.

The EWGA must be in the fully closed position while applying pressure on the EWGA lever to accurately measure the output voltage.

- If output voltage > 4.3 V

:Turn rod end clockwise (D)

- If output voltage < 4.1 V

:Turn rod end counterclockwise (E)

Specification: 4.2 +/- 0.1 V





If unable to achieve proper voltage specification it may be necessary to rotate the EWGA rod (F) 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.

Reinstall all the removed parts in reverse order of removal.

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 above.

CAUTION
Engine components are hot and can cause burns.
