RELATED VEHICLES: 2011-2014 Hyundai Sonata 2.0L Turbo; Kia Optima 2.0L Turbo

SUMMARY: P2562-Turbocharger Boost Control Position Sensor 'A' Circuit; The turbocharger waste-gate is controlled by the ECU to optimize the air/fuel ratio based on the boost output of the turbocharger. When the boost pressure in the intake manifold reaches a target pressure, the ECU opens up the waste-gate to reduce the amount of boost being delivered to the engine. When the waste-gate position sensor is out of range in the fully closed position, this DTC is set and the MIL is illuminated.
RELATED TSB:
  • 12-EM-003 or CAN-11-20-007; On some 2011-2012 model year Sonata vehicles equipped with the 2.0T (turbo-GDI) engine, the malfunction indicator light may illuminate with DTC P2562 Turbocharger Boost Control Position Sensor "A" Circuit. This bulletin describes the procedure to inspect the voltage value for boost pressure actuator position control by using GDS and adjust the EWGA (exhaust waste gate actuator) rod length if necessary.
PROBABLE CAUSES:
  • Adjustment of EWGA Control Rod
  • Electric Waste-Gate Actuator (EWGA)
  • Wiring or Connectors
  • Engine Control Unit
DIAGNOSIS:
HINT: Check to see if the above TSB has been done yet, if the TSB has not been done, perform the procedures outlined in the TSB. If it has been done proceed with the following troubleshooting.

1. Check the EWGA power circuit as shown in the diagram below.
2. Check the EWGA signal circuit, while operating the waste-gate

If the results are NOT as expected, remedy any wiring or connector issues or replace components as necessary.
If the results are as expected, suspect a faulty ECU. Mileage Symptoms Test Performed None Indicated

Boost Actuator adjustment needed

First time we saw this, was a couple of weeks ago during a 'cold' spell here, got into the 30's....no boost at all, sluggish. When it would warm up, drove a little better. We have electronic wastegates and will need adjusting occasionally...apparently. Good info in this thread....you can do it yourself or have the dealership do it for around $100 or so. Basically, what is happening is that the wastegate's boost actuator rod is out of adjustment and allowing your turbo boost to blow out too much.

Been going on for years.. worst part is customer shows up after long drive and advisor lets them wait in lounge, and reflects that back on tech who in turn has to wait for turbo related to cool down to safe working temperature to be able to work on it with out injury,, but advisor and customer dont care, the customer is "WAITING".... they want their car in 30 minutes...

Hi sbr,

I have had this code on and off for about a year. Dealer replaced solenoid about 6 mos ago.. Took it back for "adjustment" about 2 months ago. CEL light still coming on and off and it retains P2562 code most all the time. Any other ideas? It is frustrating... (2011 Sonata)
