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