Description and operation

Description

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.
