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

I installed SlyFox's bypass kit in my GX470 and it works great. No more vacuum cleaner noise and no more xmas tree lights on the instrument cluster.

Although my valves were closed, I am going to install the plates anyway just to take care of it completely.

His kit is super easy to install. It took only 10 minutes to do once I decided how I wanted to route the wire and where to cut to make it look completely stock and not show any signs of being installed.

Very, very straightforward and is much more cost effective than the two companies which sell a kit. Yes those companies sell a kit that comes with factory plugs to make it plug and play but at a cost that is 3X-5X the cost of this kit. If this was a three year old car I would likely opt for the plug and play option but I am putting it on am 11 year old car.
 
Thanks DavenLei! You should get many years out of the bypass! Enjoy.

hey slyfox75,
I read few pages, I got the p1442 code with bank 1 stuck close, that means I dont need the plates correct? Also, do you have a DIY/Video/Pictures on to how to install your kit? also whats your paypal or venmo? I'll send over the payment. How much is it?

The instructions in his kit are very thorough, with pics.

Didn't see this thread before, lucky timing for the sidebar. My valves were stuck open, I was able to get them closed, I thought, and installed a bypass but recently the codes have been coming back.

Has anyone else had the codes return with or without installing the blockoff plates? Read a bunch of pages but not seeing any mentions of it.

Was considering trying a higher resistor before blockoff plates. I started a thread here https://www.toyota-4runner.org/4th-...-air-pump-codes-after-bypass.html#post3413881

[MENTION=467719]oguzkuruca[/MENTION] No need for plates in your situation.
Bypasses are $48, Pair of plates are $40. (shipping included)
via paypal to jeffcole75 at gmail or via Venmo [MENTION=46392]JeffC[/MENTION]ole75. Make sure to include your address and yr/model if not a 4Runner.
I ship next morning after payment received. 4 pages of color instructions included(not hard install, just lots of pics)

[MENTION=58630]jbtvt[/MENTION]. Resistor change wont help.
Do you know what codes you are getting? Depending on codes we can pinpoint what you need. Could be something completely unrelated(O2, evap, ABS, etc)
 
Yep, I installed Slyfox75's kit in my 05 V8 a few weeks ago. Now I have nothing to worry about! :thumb:
Thanks again SlyFox75!

Complete removal?

I see a lot for the bypass kit, however I’m about to do some major surgery anyways on my 06 T4R Limited and am wondering if you can just remove the whole system all together? Is this a realistic possibility that isn’t more than a bypass? What is needed if so?

You cannot remove entire system with a "regular" bypass. Well.....you can. You will have CEL and multiple codes however.
You can check out Hewitt Tech website and ask Paul(owner) he has a new system that I think allows you to remove entire system @~$500 range. Most people just leave it and bypass it.(easy/cheaper/no real advantage to remove)
 
You have a 9 year old truck and you experience a problem, now you want it covered under warranty when it expired 4 years and who knows how many miles ago?!? When they don't you say," I will never buy a Toyota product again", even though you like it, until the possibility that you had to put money into it. Unless of course they give you something for free LOL.

This is borderline crazy, put any other product into the place of your 4runner. Not many companies are going to willingly replace something 4 YEARS outside of the original warranty period.


Listen, most of the times this is an easy fix, and can be done in a few hours with hand tools for NO money 90% of the time.



The inlet pipe for the air pump has a foam filter, which over time with engine heat cycles,starts to deteriorate. When it does it gets sucked into the pump (occasionally damaging some fins in the pump, generally not enough damage to cause the pump to not work), and push the little bits of chopped foam straight into the valves. This causes them to stick.

Snatch off the intake, remove the foam filter, and blow out the pump with compressed air. Remove the valves and use a power probe (or a jumper wire from a 12v source, IE your battery) to actuate the valves and remove any pieces of foam stuck. Then reassemble and you're done. Iv done this to countless tundra's and 4runners and have had VERY few need actual parts replacement, although occasionally it is necessary.


Also, LOL @ responses to get the government involved.


Not to nitpick, but the warranty enhancement isn't because of defective airpumps. Its root cause is water intrusion leading to parts failure.


I just got a P1445 code and this is the most reassuring post I've found on it so far. I'm hoping it's this simple to resolve.
 
Another plug for the SlyFox bypass. I did the bypass a few months ago now. It was one of the first things I did to my 07 V8 in the first week of owning it so I didn't have to worry about this issue. No issues so far the kit has awesome instructions, too.
 
Anyone ever run into the issue where you couldn't install the block-off plates because the bolts were too rusty? I can't even put a 10mm wrench on them. The wrench just spins. If they were easy to get to, I'd just cut them. But that's not possible given their location. My 08 left me sit earlier this week with a valve stuck open. It looks like I'll be unloading about $2,100 at the dealer soon :(

No, but heat followed by PB etc, Gatorgrip socket, pounding on next size down (10mm or 3/8"), Vice Grips, etc have gotten out bolts in worse shape than that for me

Thanks. And yes for that price I’ll just bypass. Will order today. Thanks again.
 
Effect on emissions test?

I just got my '07 V8. Been reading a lot on this subject here on the forum. I don't have symptoms of a failing pump or valves yet, but I'm considering a preemptive bypass install to avoid any issues in the future. My question: has anyone had an issue passing emissions inspection after installing? I'm in PA if that makes a difference. Thanks.
 
According to PA DMV, the test is a plug in OBD2 test. As long as you aren't throwing a code you should be fine. PM if you want a shop reco for emissions.
 
Hey slyfox, just became the new owner of an 06 GX470. So far everything is great mechanically, but I want to ensure this engine lasts forever.

Given that I don't have any CEL or currently have any shopvac sounds at startup, I don't think I have any issues currently. Also, the car has lived in the bay area its whole life so probably not a lot of cold-weather starts.

I'm ready to get your kit, but just want to know whether I also need to install the plates. I'd prefer to "do it the right way", but unclear if the plates are needed if the system is otherwise working normally. Thanks for your help mate.
