Check engine codes

Thanks to the local Autozone(s) here in town who will pull codes for free; I've found my 98 30V has thrown P332 and P411.

I believe the 332 is knock sensor on bank 2 and 411 is secondary intake flow.

Anyone have experience with the secondary intake flow or changed a knock sensor?

P0411= Secondary air injection system incorrect flow detected....that means...

Your smog pump has a leak...
check the Vaccum line(s)...It may be the one that's been recalled from audi.
