I am getting a check engine light for P0410. All parts have been checked related to the air pump and relays and what not. The dealer wont touch the car because of the cam and says its related to the cam and that I need to take the cam out in order for it to pass emissions. If I dont have the car pass emissions by Thursday, I lose my license. Is there any way it can be edited out of my PCM? I can pay cash to anyone located around chicago who can get me passed. Thanks!

 

Im no expert but i wouldnt think your code is related to the new cam maybe we can get a Tech to chime in on this one. You may have a check valve issue


Quimbo SEEYAAAH

 

P0410 = Secondary Air Injection System. Funny, my car has a cam and it didn't break the AIR system.
More Info. Stock it's set for 2 Trips, Emissions Related. Yes, you can edit it off, you also have to change the MIL enabler to no MIL. Also, I think you can set the AIR tables to zero's. I did that on mine to check my AFR at startup and warmup and didn't get a code.
The AIR pump is under the front driver's fender and vents to the 2 check valves on each side of the exhaust.
I don't have my manual here at work so I don't know the conditions for setting this DTC.
Did you remove the AIR system when you did your cam? If not, off the top of my head, you could have 1 or 2 bad check valves, the fuse for the motor is burnt out.

 

nope... air system has been fine until recently (cam has been in for months!).

 

Well, then you have the misfortune of having a crappy service dept. at the stealer. I don't know what would be accomplished if you went to them with this info anyway. They don't want to do the work. Usually the service manager could just as well be working in a tractor factory. GM's premier car and they treat it with all the respect and dignity of a 2003 Malibu.

There has to be somebody in your area to help on this...

Found this online:
It indicates an A.I.R. system malfunction per the title of your post. Specifically it means the PCM determined the heated O2 sensors voltages did not respond within the allotted time. They have to fall below 222 mV in < 1.3 seconds on both banks during closed loop operation. Or the short term fuel trim did not change more than a predetermined amount.

The above will cause the Malfunction Indicator Lamp (MIL) to come on. If after 3 consecutive ignition cycles where the diagnostic runs and passes it will go out.

Possible causes:

-Low system air flow
-Excessive exhaust system back pressure
-Moisture, water or debris ingested into the AIR pump
-Pinched, kinked, heat damaged, or deteriorated hoses or vacuum lines
-Restrictions in the pump inlet, duct, or filter

The car will run fine with the system inoperative. It only runs during startup to help the CATs light off faster. It does this by injecting air into the exhaust.

The pump is located inside the front fascia on the drivers side. You'll find its intake connected to the engines air intake. It's a small squarish box. The plumbing goes into each header. (The small tubes that come off the headers) There are also two check valves the prevent exhaust gasses from entering the AIR system plumbing. They are located next to those connections on the headers where the AIR plumbing attaches. If one of them goes bad you will get a P1415 or P1416 code. (Fairly common with aftermarket headers).

 

QUOTE from Gary Lang Chevy "If you have tampered with any engine component, your entire driveline warranty will be considered voided, along with the air system you speak of" GREAT... THANKS A LOT GUYS!!! Please if anyone can help... id be forever greatful and pay cash. THANKS!

 

I added the stuff above in the quote from an online search after I posted the first part.
Well, there is a law I have read about on this forum that says you can take him to court and he would have to prove that the cam ruined your AIR system to avoid having it fixed under warranty. I don;t remember wht it was though. Try a search, but I think the main problem right now is finding out what caused this code.
I just changed the driver's side AIR hose on my car. There is a 'T' connection on the pipe that comes out of the AIR pump. The inlet is from the pump and the to outs go to each check valve. One check valve is connected to the header on the driver's side, and the othe is behind the intake manifold. The air pump side of the connection to the check valves has a rubber hose. This rubber hose was very close to my headers on the driver's side. So close that it eventually burned a small hole in it. I didn't throw a code, I caught it while searching for another problem, but I wonder if something like that has occured on your car. If that is the case, 3" of hose and 15 minutes and 3 start, cool off, start cycles and you would be gtg.

 

Here is some info on the law:
Warranty Law

 

what year C5 ?
what other codes are being set ?

 

Wow! I can't remember the last time I didn't have to buy a sticker!! I think it may have been 1987 or so.

Shahram

 

its a 2000 and thats the only code being thrown.. (besides no tire pressure sensors) i checked the relay in the fuse panel and it engages and doesnt give any resistance in the circuit.

 

Do you have the circuit diagram ?

 

for the air pump assembly? yes, but with this 95 degree heat, id much rather have someone else look at the car. Dealership wont look at it under warranty because i have a cam in the car.
