Default Codes P0410 and P0412..... What do they mean??

My SES light came on last week and I had it checked at Auto Zone. Does anyone know what would cause these. I have a loud mouth and ram air hood, nothing else has been changed.

Thanks

Look at the top of the page, there is a big button linking you to all the codes... I think they are AIR related

The descriptions are:
Secondary Air Injection (AIR) System

Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1

But I don't know what they mean or what is causing them.

Thanks.

Did you recently have headers installed? I did w/ simms and I get those codes. !Air Pump using LS1 Edit supposedly fixes this.

No, I have not recently installed anything on my car. The only mod I have is a loud mouth, which was put on many months ago. Could my O2 sensors be bad??? Is it serious?

I get the P0410 code once in awhile. In fact, I just got it again Saturday even though I've removed the AIR pump completely. It was supposed removed from my PCM by custom programming also. Your relay could be bad. It's in the forward fuse box under the hood. (It controls the voltage to the pump).
