P2565 Turbocharger Boost Control Position Sensor A Circuit High

P2565 means the boost actuator position signal sits above the highest plausible value, typically from an open signal wire, a short to the 5 V reference or battery voltage, or a failed sensor. GM's 2018 diesel ECM table flags it at an analog reading above 95 % in 200 of 250 samples (Type A, warning lamp on the first trip). Kia service action SA149 for the 2011-2012 Sportage 2.0 T-GDI pairs P2565 with P2562, updates the engine software and adjusts the wastegate rod until the position reading lands between roughly 3.8 and 4.1 V, depending on coolant temperature. Ford special service message 53328 offers a separate vane actuator for 2020-2022 F-Super Duty 6.7 L diesels showing P2564/P2565 among other codes. P2564 is the low-side fault. Power is usually limited.

Likely causes

Open signal wire or unplugged actuator connector
Signal wire shorted to the 5 V reference or battery voltage
Wastegate actuator rod set to the wrong length (electric wastegate engines)
Failed vane actuator with integrated sensor

Symptoms

  • Loss of power, sometimes limp mode
  • Check engine light on
  • Unusual turbocharger noise on some diesels
