OK, but....

The cannister purge sustem is completely seperate from the Pulsed Secondary Air System.

The big valve by the side of the engine is for isolating the air pump when it is off. I believe there is no "EGR" valve in the system now that the car has a dual catalytic converter, dual O2 sensors, OBD-II ECU etc.

My Volvo shop manual refers to the valve that controls vacuum to the AIR valve simply as a solenoid even though it controls vacuum.

Just trying to clarify things, hope this helps. I'll refresh my knowledge tonight by reviewing the manual.
