Hyundai Sonata: Engine Control System / RCV Control Solenoid Valve Description and Operation
RCV (Recirculation Valve) Control Solenoid Valve is installed
on the cooling pan motor top and operates the RCV actuator which
controls the by-pass passage of the turbo-charger compressor.
When the throttle valve is closed during engine running
[Tip-out], crash noise of the impeller will occur because of rapid
increasing of the boost pressure. So, in this case, in order to prevent
this phenomenon, ECM maintains the appropriate boost pressure by opening
the by-pass passage.
