According to Porsche Boxster Air Injection System diagram, it shows 1 change-over valve under the intake plenum.
When I removed the intermediate air intake and the cable throttle for a complete cleaning, I found a valve mounted next to the Starter. It looks like the change-over valve. I am not sure what it is. It has two(2) nipples. One straight nipple has a tube connected a junction that connects to the Vacuum tank, intake black rubber sleeve (passenger side), etc. The other 90 degree nipple has a tube with white protective sleeve. The other end of this long (> 2ft ) tube does not connect to anything.
See picture of the valve.
Any comments or advise to what this valve is and where the 90 degree tube w/ white sleeve should be connected to?
Thanks for your help!  |
One, part number 7PP-906-270.
