Help with Troublecode (SES)

[y2kformula]

*UPDATED*
So my SES light came on. I went down to my local Autozone to use their OBDII reader and the code I got was the P1416 Auxiliary Emission Controls. Anybody know where I can get more specific info on what part needs to be fixed/replaced or anybody with experiece on this particular code. If its something easy, I would preferably want to fix this myself instead of bringing this into the dealership and get charged an arm and a leg. Thanks!

Are you sure it's P1418? Reason I'm asking is because when I looked it up at obdii.com it comes up as a J-body code for secondary air system, and nothing for the F-body. Secondary air codes aren't critical, but you need the exact code to fix the problem. Maybe it was P0418?

whoops.. i made a mistake.. it was P1416

BTW, I have a 2000 Formula

i looked up the site and it says.

P1416 Secondary Air Injection [AIR] System Bank
P1416 AIR System Bank
P1416 Secondary Air Injection [AIR] System Bank
P1416 AIR System Bank
P1416 AIR System Bank

Does something need to be replaced? I can provide more info if it would help diagnose the problem. Thanks!

Cool - hoping it was a typo or something. Easy fix, posted about this before:

Forgot to mention earlier - you don't need to go back to AZ to clear the code or reset the PCM after you replace it, SES will clear after 3 consecutive starts without a failure, but it will be stored in the PCM as a "history" code for 40 cycles.

one more thing

[y2kformula]

sorry.. i think i need 10 post to use a link

you posted the part number in the other thread
"VALVE, SECD AIR INJN CHK" GM 12565503."

Does kragens, autozone, or pepboys carry that part or do I have to go to the dealership? is there a generic part thats the same?

I found this searching online
ACDELCO Part # 2141045
Category: Air Check Valve {#12565503}
http://www.rockauto.com/catalog/cata...=FR321-2141045

it references the GM part number also but is it the same or should I stick with OEM?

thanks

Yeah, you can pick one up at a local parts store - friend of mine got his at NAPA. I posted the GM PN/description so if the store doesn't understand what part it is they can cross reference it. The PN is the same for either side too.

I also am having trouble deciphering my trouble codes. I am not sure if this is the best place to ask a question, but since I am new to the site, if I should post elsewhere, please direct me. Regarding my trouble codes, I continue to get two codes, P1641, Relay 1 Control Circuit, and P1642, Relay 2 and 3 Control Circuit. I have no idea what these codes mean, or how to remedy them. Any help would be appreciated. Thanks.
