    Do you remember which relay it was? I'm having the same P0418 and P2445 code in my '15 Tacoma and the pump does not turn on at all. I'm only seeing the 10A fuse labeled AIR PMP HTR, which I assume is for the air intake system.

    Bumping this up.. I just got the P2445 on my 13’ went into limp mode. I pulled over checked it with the scan gauge and cleared it, drove home and turn my truck off and got the whistle sound.. I guess I’ll
    Wait for the code to pop back up but I can’t make a clear heads or tails of what the actual problem here is.. I have had the unifilter mod done for a long time now, but I still don’t know or understand that the issue is here with this system..

    thanks! the kit has been on my list for a while. I had mine fixed once under warranty but those days are over. And it sucked to be stranded and needing a tow truck to the dealership.

    I had codes 2441 and 2445 pop up after doing some maintenance where I had to remove the air intake manifold... I did a cold start and could feel the SAI pump whirring; Moved on to look at the SAI valve and I noticed the vacuum line dangling. Looks like I forgot to plug it back into the MAF after my maintenance. I cleared the codes and now I'll drive around for a while and see if they ever come back. Will post and update.

    (also found out about the pump filter modification and the OEM plastic cover while reading about this system. Will be installing the clamp on filter and cover to the pump when the parts arrive)

    Update: reconnecting the vacuum line seems to have fixed it! Happy to have it be a simple one! Hopefully someone else runs into this easy fix as well!
