i've had mine come on and i worried about it for awhile, but it just went away. i read both the blink codes and the actual MIL code, and it read

P0411 Secondary Air Injection System Incorrect Flow Detected

from what i understand, your secondary air pump is part of your emissions control system. you could get it checked out, since you're still under warranty, but i honestly wouldn't worry about it too much.

I can absolutely guarantee that the air pump is not the problem on his/her car. In fact, I'd bet you 20 million dollars on it.

06/07 don't have the air pump...

Thanks for your input. I'll try to re-install and see what happens. I just don't want to mess anything up.

don't clear the CEL before you read what it is!!

1) take your car to autozone
2) ask for their OBD2 scanner, they will ask to hold onto your ID
3) plug in scanner tool in your driver side footwell (center console a little behind where your knee would be). the plug sticks out towards the left side of the car.
4) read the code, write it down
5) look it up online, post on s2ki boards
6) if it's not a problem, then take it back to autozone and clear out the code


the car threw a CEL/MIL for a reason.. don't just clear it without figuring out what it was.
