Secondary air injection issue after pump replacement

Hi!
I've got the issue for a while now. Already replaced the 2 units each side of the engine but still gets the P2447 code every time I start the engine. The code is on the bank 2 and when I use my diagnostic tool to manually trigger the system, the unit shows a fail status.

Can you guys give me any information about it to be able to complete the diagnosis? I'd like to figure out if the issue comes from the pump or a bad wire.

So if you have any wiring diagrams or any other input for me it would be really appreciated. Thanks!

 

I have the same problem with 2011 5.7. I replaced both pumps and valve. I pulled the hoses on a cold start and pumps and valves are working ( you can feel air from pumps and exhaust pressure on the valve side hoses.I can manually operate the valve and pumps with the scanner but it fails the automatic test according to my Xtool 8 s scanner and a friend’s snap on scanner. I can clear the set and pending codes but they come back and I have tried clearing the permanent code by 3 drive training sessions. You would think the computer would see that it is fixed by multiple cold starts but I have not found any one who knows the answer and I have spent hours and hours searching for how the reset works other than to go to the dealer. I have pulled the intake twice checking and cleaned MAF, throttle body, and sprayed carb cleaner in intake and checked and rechecked all wires and vacuum lines. I even smoke tested the intake looking for vacuum leaks or anything that could throw off the Computer. Almost ready for a bypass kit.

 

With P2447 check for any leaks in the air hose from pump to valve and double check the electrical connections
