Where Is The Secondary Air Injection Pump


Recommended Posts

hello and thank you for your help.

i am looking for the place of the secondary air injection pump, i can't find it in the engine compartiment.

the reason why i'am looking for it is that i have a hose (not sure of english term) between the electric change over valve and the air change valve that is missing. and the air change valve is "on" the secondary air injection pump. so if i find it i can plug in the hose.(if someone have a picture it will help me a lot)

i am very sorry for my english and hope that you can help me

it is a 2.5 boxster 1999

many thanks for taking time for reading

It would help if you update your profile so we know where you are.

If your car is a European car it doesn't have a secondary air pump. Only the OBDII cars have this device and the secondary air injection.

sorry i'm from france and my car come from germany.

i don't understand, i thought that every boxster got OBDII; mines have it

if i didn't have secondary injection air pump why did i get the Electric change-over valve ? (and also the vacuum reservoir)...

my problem is on the electric change over valve there is a hose which come from the vacuum and the hose who go to the air change over valve is missing, i think it is not good for the engine...

if i unplug the electric change over valve after some km the check engine light goes on.

i am very sorry if i explain bad my problem

thank you for your help
