Turbocharger Bypass Valve

The turbocharger bypass valve prevents back flow through the turbocharger when the throttle is rapidly closed to avoid undesirable noise. The high pressure downstream of the turbocharger is vented back to the intake air upstream when the turbocharger bypass valve is open reducing pressure in the system.

The turbocharger bypass valve is solenoid controlled and located between the turbocharger intake and the turbocharger boost pressure output to the CAC.
