Just read through this thread for the first time and I am noticing the majority of 4Runners on here that have the air pump problem are 2005 with a few 2006 and one 2007. I have two 2004s both with V8 and neither have had the problem. So are 2003 and 2004 in the clear with this? I know Toyota went to VVT-i for the V8 in 2005 so maybe that has something to do with it.

P1445 Question
I have also just experienced the dreaded P1445 code, I think it said ("Secondary Air Injection Pump failure") at 155,000 miles on my 2005 V8 4Runner. Any updates on this on a work around? Also more importantly can I still drive my car for a little bit until I figure out what to do? I don't want to cause more damage and lead to more $$$. I also have to tow my boat in to get it winterized in a few days. Should I be OK to continue to drive it until I figure something out? Thanks!

Hey guys.....this issue is also related to the AIP BYpass mods so many of us have "had" to do in order to avoid the expense and hassle of the failing system(Pump, valves, air switching device)...all of which can fail.

Couple threads to check out.....

Secondary Air Injection Pump Failure on V8's! Important!

p2440, That f'ing pump!!!!!!

I still sell the bypasses if needed.
$45 shipped. PM me.

Just wanted to share what I found. You may already know but I haven't ran into it this forum yet. I also had p2441, p1442 and p1445 codes when I purchased it and was pretty horrified when I started reading up on it. Luckily I found something the next day, right before ordering parts from the dealer and looking to have someone do the labor for me. An engineer who I believe owns a Tundra or one of the Toyota v8 vehicle made a bypass module and exhaust block off plates related !! I ordered one, installed it and it Worked!! Cleared the codes, been about a week now and all good!!

It was around $155, I just wanted to share as this saved me thousands and could make others here happy too! Here is a link to it.

Air Induction Pump Bypass Module - AIP Valve Bypass

I ordered one through his ebay... I installed it myself. Pretty straight forward but more like a 2.5-3 hour install for me taking my time with the wiring.
Taking off the front wheels to do the exhaust block plates was the way to go. Maybe tundras have more room to do it without going through the fender wells but on the 4runner it was way easier that way. Hopefully it helps others!
Do you know if it would work for code P2445 secondary air injection pump stuck off bank 1

I am new here but thought I would chime in as I am looking for a workaround on my 4runner. Just like everyone else I love the vehicle, it's amazing. But I am FORCED to drive around with a Christmas tree of lights on at all times. I have code P1445 and was quoted $2500 to fix at my local Toy shop. I would love to hear if anyone has a workaround on this. I don't know if I will be able to use this vehicle in any other state other than the one I am in now which doesn't check emissions.

yeah you need a bypass.
$48 shipped.
Email me at jeffcolemaps at gmail
The bypass will fix your issues and remove the lights.
MANY people use the bypasses in emission states. It will not effect your test results and the testers will not know it is there. Hope that helps.

Need to figure out some way to get the computer to stop responding to those codes. Any ideas???
