Description

Installed on the upper part of the engine cooling fan, the RCV (Recirculation Valve) control solenoid valve operates the RCV actuator to control the bypass passage of the turbocharger compressor. When the throttle valve closes during engine operation [Tip Out], a collision noise may be generated by the impeller due to a rapid increase in boost pressure. In this case, to prevent this phenomenon, the ECM maintains the appropriate boost pressure by opening the bypass passage.
