Location of secondary air injection pump? (1 Viewer)

[Lexzilla]

Throwing P0418 secondary air injection system A relay. Best I can tell is that this code is usually the pump and not one of the valves. But I can't find a good diagram or picture of its location on my 09 lx570...

Don't think you will like the answer.
Pretty sure it is these 2 canisters. (I stand corrected. These are the valves, not the pumps)

I believe those are just the valves and the pumps themselves are in the front passenger side behind the bumper.

Or at least that's where I hear the very distinct electric-motor-powered-pump-like whirring sound coming from when I cold start my truck.. And where those plastic hoses lead to.

Yes, those are the valves thank goodness.
