DTC P2261-00: Turbocharger-Supercharger System Bypass Valve - Mechanical: General Description
WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
The Recirculation Valve (RCV) control solenoid valve prevents back flow through the turbocharger when the throttle is rapidly closed to avoid undesirable noise. The high pressure downstream of the turbocharger is vented back to the intake air upstream when the RCV control solenoid valve is open reducing pressure in the system.
