Thread: 2006 Pontiac Grand Prix w/3800 p0411 code

Hello, I am new to the group and I have a problem...

I have a 2006 Pontiac Grand Prix w/3800 and I am getting a check engine code --- p0411 code Secondary air injection system incorrect flow detected, Where do I start ???

just "search" dude. never had that code before.....good luck

I'll look it up tomorrow at work for you... You look them up in the service manuals for more details and what to start checking. I suggest you get the service manuals for the car if you want to work on them yourself.

OK I looked it up and it is too much info to post here.
