DTC P0035-00: Turbocharger/Supercharger Bypass Valve Control Circuit High: General Description

RCV (Recirculation Valve) is mounted on top of the intercooler inlet pipe. It functions as a controller of bypass passage for turbo charger compressor. If the throttle body gets closed suddenly during engine running, boost pressure gets higher. RCV prevents this high pressure air from moving reversely and making an impact noise with impeller of compressor by sending this high pressure air into compressor.
