EWGA INSPECTION AND ADJUSTMENT PROCEDURE
On some Sportage (SL) vehicles equipped with 2.0 T-GDI engines, the Malfunction Indicator
Lamp (MIL) may illuminate with a stored, or active, P2562 DTC - Turbocharger Boost Control
Position Sensor ‘A’ Circuit Range / Performance. In some instances, the voltage reading for
the closed throttle wastegate actuator may be too high or too low and may need to be
adjusted. If you encounter a vehicle with this DTC and you have completed the diagnostic test
procedures according to KGIS, then follow the adjustment procedure outlined in this article to
resolve the concern.

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.
 NOTICE
The screens above are for
demonstrative purposes only.
Actual content on screens may
vary by model.
2. Without starting the engine, cycle the ignition ON for 5 seconds. Then, switch the
ignition OFF for 5 seconds. Perform this step for a total of 5 cycles. After completing the
5 cycles, leave the ignition in the ON position to access GDS Engine > Current Data.
 NOTICE
Do not start the engine. This is critical to read the correct adaptation value.

3. Under Current Data, select
“Adaptation Value for the
lower mechanical Stop of
Boost Pressure”.
4. If the voltage is less than or equal to 4.2V, no adjustment will be needed.
If the voltage is greater than or equal to 4.3V; then adjust the EWGA rod length
following the EWGA ADJUSTMENT PROCEDURE below.
EWGA Adjustment Procedure:
1. Open the hood and support it securely.
WARNING
To avoid possible injury, allow the engine to cool down before performing the
procedure.
2. Remove the turbocharger upper heat shield bolt (A) and remove the heat shield (Fig. 1).
3. Loosen the rod end lock nut (B), remove the retaining clip (C) and retaining pin (D) (Fig. 2).

4. Adjust the rod end by rotating it clockwise or counterclockwise until specification is within
range (Fig 3). Then, temporarily install the rod end, tighten the rod end lock nut and check
the “Adaptation Value for the lower mechanical stop of boost pressure” using GDS
(See table below).
Fig. 3
 NOTICE
The EWGA must be in the fully closed
position while applying pressure on the
EWGA lever to accurately measure the
output (Fig. 4).

 NOTICE
After an adjustment is made without starting the engine, cycle the ignition OFF for
5 seconds and then turn the ignition ON for 5 seconds. This must be completed a
total of 5 times for the adaptation value to change. If this step is not completed,
the voltage will not adapt as described in this pitstop. Adaptation values can only
be changed by cycling the ignition key after the adjustment was performed.

5. If unable to achieve proper voltage specification, it may be necessary to rotate the
EWGA rod (F), in ½ turn increments, to achieve proper voltage (Fig 5).

6. If the output voltage is not within specification, repeat step 4 above until specification is
within range.
7. Reinstall heat shield and retaining clip by reversing the order of removal.
8. Clear any remaining DTCs and start the engine to confirm proper operation.
 NOTICE
The procedure above may also be used when EWGA replacement is required.
