Recirculation Valve (RCV)
WARNING: This page is about a different variant/trim than selected.
Recirculation Valve (RCV) is mounted on top of the intercooler inlet pipe. It controls the bypass passage of a turbocharger compressor.
If the throttle body closes suddenly while the engine is running, boost pressure will increase. The RCV bypasses to prevents this high-pressure air from back-flowing and impacting compressor impellers causing noise.
