Shutter Valve Actuators
WARNING: This page is about a different car, the 2001 Mazda Protege, 2001 Mazda Millenia, 2001 Mazda MX-5 Miata, 2001 Mazda MPV, and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect vacuum hose from shutter valve actuators No. 1 and 2. For 626, see VACUUM DIAGRAMS article. For Millenia, see Figure . On all models, connect vacuum pump to VRIS shutter valve actuator. Apply vacuum to each VRIS shutter valve actuator separately and ensure VRIS shutter valve rod retracts. If operation is not as specified, remove suspect VRIS shutter valve actuator and ensure actuator moves freely. Replace VRIS shutter valve actuators as necessary.
