Air pump switchover valve, function - GF14.30-P-3103-03HA
The air pump switchover valve (Y32) is actuated directly for a released air injection by the ME-SFI [ME] control unit (N3/10) by means of a ground signal. This causes anchor plate (a) to be pulled by solenoid (d), and rubber seal (f) shuts off air supply (1).
The connection between port 2 and port 3 is opened. Thus there is a vacuum built up from the intake pipe to the aspirator shutoff valves.
In a deenergized condition the connection between connection 1 and connection is reestablished, whereby connection 3 is ventilated.
