Kia Forte: Engine Control System / RCV Control Solenoid Valve

Kia Forte 2019-2021 (BD) Service Manual / Engine Control / Fuel System / Engine Control System / RCV Control Solenoid Valve


Coil Resistance(Ω)
28.3 - 31.1 [20°C(68°F)]

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.
