P2562: Turbocharger Boost Control Position Sensor A Circuit — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Turbocharger Boost Control Position Sensor A Circuit. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

  • The engine warning lamp may appear, sometimes with reduced acceleration or limited turbo response.
  • Some vehicles may enter a power-limited mode when boost actuator feedback cannot be trusted.

Possible causes

  • Faulty boost-control actuator position sensing or damaged wiring between the sensor and controller.
  • Loose, corroded or heat-damaged connectors can interrupt the position signal.

What to check

  • Save P2562 and associated boost or actuator faults before clearing codes.
  • Inspect the position-sensor connector, harness and nearby actuator hardware for damage.
  • Test the sensor's supply, ground and feedback circuit as specified for the vehicle, then observe position feedback with a compatible scan tool.

Also written as: P2562-00, P256200 (some scan tools add the fault-type byte, e.g. -00).
