Code P0410 chasedown-need input
I know, it has been beat to death. But, looking for guidance.
No air from pump at separated hose connection on driver's side on 2001 LS1. From what I read here, it could be micro relay 33, the pump or a vacuum line under battery. Vacuum line looks fine.The code throws every 30-50 miles or so. Darned yellow light makes me crazy.
1. So, can I switch out relay 39(fog light ) with relay 33 to see if the relay is bad?
2. If so, where is best place to buy a relay?
3. Are any of the handheld aftermarket programmers capable of tuning out the AIR? No way am I going to a dealer.
Thanks , all !

Do you have vacuum at the air pump shut off valve at start up?

#1&2: Sure, try switching the relays as you suggested. They are common relays, and Advance Auto or Auto Zone should have or can get them.
#3: You will need a programmer such as a Tech 2 or HP Tuners to delete the Secondary AIR program from the PCM.
Thanks lucky. The link you posted w/pics, while I was still typing, is worth a thousand words!

I'm going to the link,but
to answer the questions:
The pump does not seem to be running-can't hear it anyway and there is no air coming from the pump end of the parted driver's side hose.
Thanks for the info and the link.
