Kia Sportage: RCV Control Solenoid Valve | Canister Close Valve (CCV)

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Fuel System / Engine Control System / RCV Control Solenoid Valve | Canister Close Valve (CCV)

Description and Operation

 Description

RCV (Recirculation Valve) Control Solenoid Valve is installed on the intercooler inlet pipe and operates the RCV actuator which controls the by-pass passage of the turbocharger compressor.

When the throttle is closed, while the engine is running at cruise rpm (tip-out), the turbocharger boost pressure raises 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.
