I could be mistaken but to me it's the same as the P1416...........

here is another link of a member who did a retrofit on the P0410 code.and it looks the same as the retrofit P1416 code............

I'm still learning about these codes myself so .....I hope someone will verify or correct my assumption

by the way I'm not promoting the retrofit procedure....I only post it because it came up using the search function..........maybe you can find a better answer using the search tool.............

I know the P1416 code I just replaced my secondary air check valve (passenger side just behind the Intake) Thursday.

Could this be the vacuum leak I mentioned earlier?

If it were me, I would assume IT IS..........if you replaced the valve then the vale "should" be good. I've purchased defective parts before but I truly doubt this is the case.

You may have a pinched vacuum hose, or maybe one that isn't connected. I've been studying a lot of intake removal information and it seems there are special notes regarding getting the vacuum hoses connected right.

You are further ahead on this than I am......so I can't truly help. I can only offer you suggestions............you're the one who did the work, so only you can say what it may be if you think back to the work you did.
