Installed on the intercooler inlet pipe, the RCV (Recirculation Valve) Control
Solenoid Valve operates the RCV actuator which controls the by-pass passage of the
turbocharger compressor. When the throttle is closed with the engine running at
cruise rpm (tip-out), the turbocharger boost pressure increases rapidly. The pressure
wave strikes a compressor blades causing a knocking noise. To prevent this, the
ECM opens the recirculation valve which allows excessive boost pressure to vent
back to the air cleaner side of the turbocharger compressor.
