Intake Manifold Switchover Valve: Description and Operation
Resonance Intake Manifold Switchover Valve (Y22/6) And Flap (22) Unit
PURPOSE
The HFM-SFI control module controls the resonance intake manifold flap via the resonance intake manifold switchover valve (Y22/6). The
switchover valve connects the resonance flap to vacuum from the throttle valve assembly.
OPERATION
When the HFM-SFI control module energizes the switchover valve, the valve opens and vacuum reaches the resonance flap. The flap controls the
airflow in the intake manifold.
