P0410 code on my new 99
Hi Everyone,
Driving home from buying my new 99 the CEL came on. When I got home I bought a code scanner and found the code is P0410 secondary air pump system. Today I pulled the battery and checked - no acid leak evidence.
Most of what I find here is related to the air pump itself or vacuum lines - usually under the battery and damaged by battery acid. I'm a little confused because I pulled the tray and searched every where in that area, but no vacuum lines at all. Am I missing something? Can you only see those lines from the bottom side of the car?
AFAIK, the car is bone stock, and I don't see any capped connectors or anything else to make me think anything has been changed/removed, etc.
Of course, I can't pass smog here in CA with the CEL on, so I have to fix this before I can complete my registration.

The vacuum lines you refer to, are for a 2000+ setup, which uses manifold vacuum to control the valve on the pump.

Since you have a 99, you have two relays for the system to operate, both of which receive 12 volts from Maxifuse 50(hot at all times, in the underhood fusebox), and are grounded by the PCM. Micro relay #33 provides 12 volts to the air pump itself, while micro relay #40 provides 12 volts to the valve on the pump. Both are located in the underhood fuse box. So if micro relay #33 is bad, the pump does not run, and if #40 is bad, the valve does not open, allowing air to flow through the check valves.
The vacuum lines you refer to, are for a 2000+ setup, which uses manifold vacuum to control the valve on the pump.

Awesome! I'll check that out ASAP!

FYI, you do not need a code reader for the C-5's to get to all of the codes. The DIC has the ability to show you everything and more, than a standard code reader. Been posted tons of times in here!

We need a sticky here for things like that so that us C5 noobs can refer to it. I would never heve expected such a feature, so I didn't even think to look for it.

Did you get an owners manual when you bought the car? If not here is a link to pdf file owner manuals.. Make sure you read the manual front to back.. Lots of good info to learn

Isn't the elec air pump under the diverr's side headlight ?? and not under the battery tray ?? Typically a 2nd air code is related to sticking check valves ---especially on a car thats been sitting for awhile--I would 1st on the divers side--disconnect the rubber air hose that pushes air out to the exh system--after disconnecting--start the eng and see if you can feel or hear air being pumped out---this would confirm IF t=your air pumps is working---( remember that it only runs for a few seconds after starting so best is to have a frind help you)
THEN is the pump is working---remove the air check valves and clean the carbon out with brakeclean---It may be hard to remove them but it you can't at least douse them in brake clean and let them soak and break-up the carbon--there is also one on the other side (pass) typically located on the firewall---
PS: any tuner can turn off all the AIR related codes permanently so they won't affect a smog--and never pop up again--Often these AIR code issues are time consuming and you end up scrathing your head and can't resolve them--Best is to delete them permantley

I have a new air pump for it and am going to work on it tomorrow evening. I'll check the function first and then go from there. I also found another post about the valve assembly next to the pump going bad, so that will be the second thing I check. I can always return the pump if I don't need it. I know of a shop that should be able to deactivate the code if I have to go that route.

I removed the small lower aft. wheel well panel as well.
I see that you have removed the tray,Sorry! I wasn't able to see the acid damage on mine until I removed the small panel in the wheel well and the the computer cover. That let me see the frame. Hopefuly yours will be damage free.

Hey Dale,
Yes, mine was damage-free. Guess I got lucky there.
I may not be able to return the code reader as it was one of those sealed-in-plastic deals. I opened it carefully, but I need to see the store manager tomorrow to find out about returning it.
I'm going to take along the info on using the DIC to pull codes to back up the fact that I really don't need the $129 reader to check codes.

We checked out the pump last week and definitely no air flow out of it. Marc at Vettenuts.net fixed me up with a good used one. Hopefully I get the time to get it in this week so I can complete my registration and get CA plates on it.
