P2562 flags a general electrical problem in the circuit of the position sensor that reports where turbocharger boost actuator A stands - the variable vane linkage on many diesels, the electric wastegate actuator on turbo petrol engines. The engine computer receives a signal it cannot use at all, as opposed to a wrong position (P2563), a signal pinned low or high (P2564/P2565) or brief dropouts (P2566). Kia service actions SA078 and SA119A for the 2011 and 2012 Optima with the 2.0 T-GDI engine name P2562 together with P2565; the fix is to read the actuator position voltage with the scan tool and reset the rod length of the electronic wastegate actuator. With the code present, boost is usually cut back and the warning lamp is lit.

Likely causes

Open or corroded wiring or connector between position sensor and engine computer
Electronic wastegate actuator rod length out of adjustment
Position sensor inside the actuator failed

Symptoms

  • Reduced power because boost is limited
  • Check engine light on
  • P2565 stored at the same time on some engines
