Description and operation
Description
Installed on the cooling pan motor top, the RCV (Recirculation Valve) Control Solenoid Valve operates the RCV actuator to control the by-pass passage of the turbocharger compressor.
When the throttle valve is closed during engine running [Tip-out], crash noise will be generated from the impeller due to rapid surge in boost pressure. So, in this case, in order to prevent this phenomenon, ECM maintains the appropriate boost pressure by opening the by-pass passage.
