Description and Operation

Description

Installed on the upper part of the cooling pan motor, the RCV (Recirculation Valve) solenoid valve controls the RCV actuator to control the bypass passage of the turbocharger compressor. When the throttle valve closes during engine operation [Tip-out], abnormal noise will be generated by the impeller due to a rapid drop in boost pressure. Therefore, to prevent this phenomenon, the ECM maintains the appropriate boost pressure by opening the bypass passage.
