Hello and welcome!

DTC P2563: Turbocharger Boost Control Position Sensor Performance
The position of the turbocharger vanes is controlled by the engine control module (ECM). The ECM utilizes a turbocharger vane control solenoid valve to control the turbocharger vanes, and a turbocharger vane position sensor to verify the position of the vanes. The ECM will vary the boost dependant upon the load requirements of the engine. Movement of the TC position sensor from the closed position to the open position provides the ECM with a signal voltage through the position sensor signal circuit.

First i would start by checking and or replacing the turbocharger vane position sensor.

It is somewhat common for this part to intermittently fail and set this code.

Worse case scenario is the vanes in the turbocharger are stuck.

If you have a volt/ ohm meter some basic checks can be done to test for proper signal to the position senor.
