The SES light came on, scanned it with ProScan and it showed a code: 1416 powertrain: secondary air injection (air) system bank 2

OK, so I got a problem on the passenger side but what exactly is it?

Looked online but was unable to find a good chart listing or database. What do you use?

Thanks!

 

It's most likely just a clogged passenger side air check valve. It's screws into the metal air tube coming of the exhaust manifold, then connects with a hose clamp on the other side. Easy to replace yourself and not expensive. GM PN is 12565503.

 

I just had the same code and swapped out both air check valves while I was at it, code is gone!
