SES Code Question

[AxeGrinder101]

Hi all.
My SES light came on earlier while driving.
Got home and did a scan.
Code reads as P1415 which is Secondary Air Injection System Valve B Malfunction.

I took a look under the hood with a flash light to check wire connections and a couple of hoses, but not much else since it's late and too dark.
Will give it a thorough look first thing tomorrow morning.

Any ideas or suggestions on where or what to look for?
Any input is greatly appreciated.

Thanks

Replace the driverside air check valve...it's like $20 at autozone, then clear the code. I'd replace the passenger side also but that's up to you....the dtc for that side is p1416. The check valve is a black valve connected to a metal A.I.R. tube by the intake manifold...there's one on each side a few inches above and to the side on the manifold. You'll know it when you see them...they're identical. Internet troubleshootin is not 100% accurate of course...but that should solve your dtc.

The valve is GM PN 12565503 - might help you at the parts counter.
