RCV (Recirculation Valve) Control Solenoid Valve is installed
on the intercooler inlet pipe and operates the RCV actuator which
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 boost pressure raises 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.
