New to the forum but not to Grand Prix. Owned and '83 back in the day. Was glad to see that rust bucket go. Picked up an '06 Base a week ago for my daughter but need to fix er up first. Some minor issues since it's already got 146k on it. Wish the link for the CEL codes would work!

Thanks Smoke. I know what my code is, just don't know what to do with it. P2340
01-06-2013
Code P2340 does not come up on alldata, you sure thats right?
01-06-2013
Crap. I meant P2430. (I have a bumper sticker that says "Dyslexic if you're Honk!")
01-06-2013
you put the same number...

No he didnt.
P2430 is a secondary air injection problem.

Possible Causes Setting Conditions
- AIR pressure sensor connector is damaged (check pins for damage, moisture)

So, where is this elusive Secondary Air Injection System Air Flow/Pressure Sensor Circuit? My manual hasn't arrived yet.

If I remember right it's in the front bumper cover in front of the left wheel usually water fill up in the pump and causes a short and blows the fuse. The the fuse if its blown that's most likely your problem. Take the left side splash shield off and pull the lower hose off the pump usually water will come running out. In the cold they will freeze and bust also

Well strike one. My Grand Prix is nothing like the car in this video. The fuse for the air pump is 50 amp, (and not blown) AND I just popped out both headlights and no pump tucked into the fender where the video shows.Any other suggestions guys?
Edit-It's hard to see it, but it appears that I have an actual pump, driven by the serpentine belt. Is that possible?
My Haynes manual is worthless.
Edit- FOUND IT. It's in the engine compartment right under the air filter box about a mile and a half down. Hard as hell to get to. Yes, it's electric, full of water, and corroded. Takes a suction of air right out of the air intake, so yes, dumb-a$$ GM Engineers.... it will suck in water too! There's another $100 to stick in the black hole. Any opinions on which brand to buy or avoid?
