'01 northstar help, code P0410

A coworkers cadillac is throwing this code, and upon startup it will idle poorly, making what I can only describe as a panting sound. (literally like a dog)

 

She had it scanned at autozone and the code showed a "secondary air injection system fault"

 

Could this be an emissions problem? What the hell is secondary air injection? I'm not familiar with Northstars, so let the google searching begin.

 

Thanks,

Shaun

Likely a non-working air pump or one way valve. Air injection pumps fresh air into the exhaust to speed up the catalitic converter function on startup. If you're getting a noise something is likely dying a slow death. Check the system for water intrusion.
