P2562 Turbo boost control position sensor circuit fault

P2562 turbocharger boost control position sensor A circuit

Monitor

The reference page rates this as moderate (to serious): weak acceleration, poor economy and a possible hard start, with no immediate hazard.

It gets more serious if:

  • Inspect soon: Inspect soon if the check engine light flashes, power drops sharply, or the engine will not start. The reference page lists a flashing light and weak performance.

P2562 in short

P2562 means the computer saw a fault in the position sensor circuit for the turbo boost control. A bad sensor, damaged wiring, or an actuator out of adjustment is likely. On 2011-2012 Kia Sportage and Optima 2.0 turbos it has a bulletin. Expect weak power; get it checked soon.

The turbocharger boost is controlled by an actuator or vane that moves, and a position sensor tells the computer where it is. P2562 is the general circuit code for that position sensor, and it sets when the reading stays outside its set range.

The usual causes are a bad sensor, wiring or connector damage with a short or open signal circuit, or a turbo or actuator that is out of adjustment. The computer itself is rare.

Kia found this on 2011-2012 Sportage and Optima 2.0 T-GDI engines: its bulletins have the ECM reflashed and the electronic waste gate actuator rod length checked or adjusted.

Most likely causes

  1. Sensor, wiring or connector fault in the boost control position circuit

    Common general cause
    Why it ranks here
    Reference pages list a damaged position sensor, an open ground and shorted or open signal circuits as the main causes.
    What would change this
    Rises if the harness or connector is damaged or sensor voltage is out of range on a scan tool. Falls if the circuit tests good.

  2. Electronic waste gate actuator rod out of adjustment or ECM software (2011-2012 Kia Sportage and Optima 2.0 T-GDI)

    Supported by vehicle data
    Why it ranks here
    Kia bulletins TSB 130, TSB-ENG130R1, TSB-ENG138 and TSB-ENG099R3 cover P2562 and/or P2565 on 2.0 T-GDI Sportage and Optima, with a reflash and a check or adjustment of the actuator rod. Summaries only.
    What would change this
    Rises on an affected Kia in the built-date ranges. Falls on other vehicles.

  3. Boost leak or loose hose clamp

    Possible — needs testing
    Why it ranks here
    The P2562 reference page lists leaking hoses and loose clamps as related causes to check.
    What would change this
    Rises if a boost leak test fails. Falls if the system holds pressure.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read all codes and watch the boost position sensor value and the commanded position on a scan tool.

    Low riskTool: scan tool with live data

    • IfSensor voltage is out of range or stuck

      It meansCheck the sensor circuit and actuator.

      Go to step 2

    • IfValues look normal

      It meansCheck bulletins.

      Go to step 3

  2. Inspect the actuator wiring and connector for damage, and have the actuator and turbo checked.

    Best left to a shopTool: multimeter, boost leak tester

    Warning:Turbo parts get very hot, and the system is under pressure when running. Leave testing to a shop.

  3. Ask a dealer whether the vehicle has a bulletin for these codes (Kia 2.0 T-GDI Sportage and Optima).

    Low risk

Symptoms

  • Check engine light, sometimes flashing Gets more serious: stop and have it checked.
  • Weak acceleration or low power
  • Poor fuel economy or a hard start

Compare with: Check engine light with loss of power

Is it safe to drive with this code?

Usually for a short time, but you may have weak power or a hard start. Get it checked soon, especially if the check engine light flashes.
