So for anybody wanting to make a DIY car repair video they should watch your video to learn how to do it. Very very well done. Camera work was nice. Steady and on point. The audio was a good volume and you spoke clearly and you'll explain stuff as you went with out "uh" 'um" and dead air time. It was very helpful for me. Thank you
I want to thank you. I have a 2013 Buick Lacrosse that had a P0411 code for awhile. The other day I took the valve apart and saw a bunch of carbon buildup. A full can of brake clean and thorough scrapping/cleaning, my CEL went off today!
Excellent video, sir! Very thorough! Like that you took apart the old valve and showed us how it was stuck. I am going to take mine apart and gently clean it, so this really helped! You can also clean a PCV instead of buying a new one. Carb cleaner is the key. Thanks a million! (I didn't even know there was such a thing as a secondary air injection system until I got a code...)
I replaced this very easily and cleaned throttle body too. Car is running smooth, rough idle is gone, but it is still running lean with check engine light for some reason 🤷♂️ but man, you RUclips guys are amazing. I’m no mechanic at all, but this was a breeze.
You can also clean it and put it back on. I did. It worked well until recently. The screws started coming lose, so perhaps use thread locker on the tiny screws that hold the flap to the part.
Wow dude, have you've checked around, what a mechanic's shop would've charged for labor? I'm "VERY" curious to know that, as I'm sure that ALL of us are? You've saved a lot of $ doing it yourself! Good Job! Jimmy, Marcel in Yuma
I have that same year GMC Envoy but mine is black. I just got that check engine light code last week. I’m gonna take a look at it and see what caused the light to come on
Hi there! I was taking the rear hose off, and while moving a bit out of the way to remove the nuts, I heard a small crack and saw that the hose had snapped off. Any suggestions? Thank you!
Great video... I am having similar issue to you i believe with a 2010 mercedes e class. I have the code but also my 2ndary air pump makes noise when i start the car so I know it runs. On my car however there are like 3 different valves involved with this thing. There are two check valves (or shutoff valves as benz calls them) for the left and right bank i believe. Then there is a diverter valve which I think is what you replaced here. Is that likely what my issue is? It says the flow of air is low on both banks so I think it would be unlikely for both of those check valves to fail at the same time. I am not really sure what the diverter valve does however.
My car has the code in the winter, but around spring it goes away. I guess water gets in & freezes. My question is: if I dump the water, will this solve my problem? Thanks in advance
I replaced my valve, pump, one oxygen sensor, and got the relay tested at Oreilly's. I think I will take my check valve apart to inspect it. It says the check valve is stuck open.
That looks like the same engine as my 06 h3 hummer. Inline 5. My truck doesn't have that. But it does have where if I wanted I could put one on. I have always wondered why that spot was there. Transmission dipstick is connected to it but no blower or whatever it's called. Now I know GM decided they didn't need it for my hummer. Now I'm wondering what was the replaced and why GM decided 06 h3 hummer didn't need it. Nevertheless. Good fix once again. Next Sunday I will be replace evap canister and purge in the front. Code said the front need replacing but I figured I'd just like you did. Replace the whole system. Parts came in today from Amazon lol. Issues was every time I filled up gas tank. It wouldn't start. Unless I floored it and let it rev for a moment. Then it would mellow out. But only happens when I fill the tank all the way. Check engine light didn't come on right away. Then when I used my scanner it said pending. But gave me a code which allowed me to look up the issue.
I did get my secondary air valve replaced and the check engine light came back on with the same code. I’m assuming the secondary air pump, the relay to the pump, or one of the oxygen sensors is bad and needs replacing. Ima have my mechanic check it out again and see what he says.
My air injection pump is good, my relay is good and my fuse is good. Any idea what to check next for P0410?...thks..jc...and no carbon in diverter valve
just Split them open & scrub with diesel quickly wash with water & air dry them before finally soda blasting the surface oil stains away down to bare aluminum. They will look & function like new again if the seals internally are still good obviously .
That’s a tuff question. All have there strengths and weaknesses. I love the ‘95 Suburban because of its nostalgia and simplicity. It’s just enough modern but just enough vintage. The sweet spot. The ‘03 is super comfy and has the amazing 5.3L engine. The ‘05 Envoy has a great engine too (the Vortec 4200 inline 6) and gets the best mileage of all of them but it’s a bit small and most of all I can’t really sleep in there 😜. If I had to keep just one it’d probably be the ‘03 just because it meets a lot of our needs and still has a super comfy ride as well as being very reliable. 🤙
No. It is a secondary air pump valve. The big hose is connected to a air injection pump (fan). When the valve opens it lets the air into the exhaust manifold to burn any unburnt fuel that enters the exhaust system. Their is a relay that allows vacuum to reach the diaphragm on top of the valve which pulls the valve to the open position. So this valve only opens when the engine is at less than operating temperature.
I have a GMC Terrain 2013 with a P0411 check engine code and the mechanic told me it was the air pump that was faulty. I replaced it, the light went away, only for a day though and the next day the check engine light came back on. Now I’m stuck with a brand new pump and an old one that still works. Based on your video, the relay is working fine so its going to be the valve what they’ll need to check next.
For what it's worth, I have a 2013 Equinox 2.4 with the same problem. If it's not the check valves (there are two of them, about $140 apiece), then the other problem is the air injection ports get clogged up with carbon, there's a service bulletin for that. Unfortunately, that is a a difficult repair because it involves removing the exhaust manifold to clear the carbon out. I'm really hoping that's not my problem.
@@davesherman74 My mechanic is still working on this, there was a slight crack on the secondary air injection pipe and he had it welded, plus the electrical connector that goes into the Check Valve was burnt so I had it replaced. But the issue remains, I’ve taken the car back this morning and he’s going to check the manifold and clean out the injection ports. I’m really hoping this is going to be it
@@davesherman74 After test driving the car for the past two days, I can say that the problem was indeed the air injection ports. After literally trying everything else, replacing the air pump, checking the air injection hose, welding a crack in the air injection pipe, replacing an electrical connector for the check valve, making sure both check valves worked properly, it all came down to cleaning the air injection ports and the manifolds, there was a lot of carbon buildup. It was time consuming and expensive but the check engine hasn’t come back on since Thursday. How’s your car doing?
@@pleiadianaran I've replaced both check valves since they were both loaded with soot. Replacing one improved the pressure slightly, replacing the other seems to have helped some more. If it doesn't fix it, I may have to take it to the shop to have them clear the injection ports.
@@davesherman74 Luckily I didn’t have to replace the check valves, they’re quite expensive ($270 a pop). What I did have to do though, was replace the Intake and Exhaust VVT Solenoids, I got a P0013, P0011 and P0010, all this within the last 3 months.
Good thing you don’t have the Toyota 5.7V8. You gotta remove the intake manifold to change the SAI valves. Dealership charges upwards of $2,500 to replace them.
@corey Babcock same here. I can so it myself for just the price of parts, but I’ve read on many Tundra forums and Facebook groups that the stealerships charge an outrageous fee for this job.
I know this is for p0410…. But I need help with P0455 large leak in secondary air system. Would this part cause this code? I have the same identical truck v6. I have changed the vapor canister, fuel filler line, gas cap, secondary air pump and relay. I am still getting the P0455 code. I did a smoke test and it confused me more. I am hoping someone can guide me on what to do next. I recorded the smoke test and can send it if it would help me further
My '04 Envoy has 280K miles on it and hasn't thrown this code, but I replaced that exact part a year ago just because I knew it'd eventually fail like his did. As with everything, there are always some duds that come of the line.
my 07' Trailblazer has 203k miles, hasn't seen it (that I know of, and does not appear to have been replaced), however.. my 05' Envoy with 136k has the issue. so :P
what are the symptoms of air injection system failure? I have the same code for my TB 2004. I have low torque and high revs. Any advise would be highly appreciated.
@@bandittweintraub idle is good, but there is a strange bearing noise from the pump below for about 10 seconds at cold startup then gradually fades away. Idle is at 600 with no vibration. I feel the air pressure is being blocked somewhere because the torque is good. I highly suspect its the valve on top which has gone bad? Also I removed the valve and checked it with 12V battery and I can hear the clicks. Still not sure if its good or bad.
What is the purpose of that thing anyway I would have just got the plunger moving and working again and thrown it right back in hahaha so many unnecessary parts on newer cars
Hi Jimmy, we are producer from China for this air/smog check valve, and it happens that we are developping this valve now. And i think we can have some cooperation for asking you to test our valve. Can you pls give your mail to contact for further discussion?

Success!! Nice job! Good to see a non-mechanic like me apply some logic, a little research and some elbow grease and get it fixed. Enjoyed the vid!
Yep, can figure almost anything out with RUclips these days… glad you enjoyed! 👍👍

You can also clean a PCV instead of buying a new one. Carb cleaner is the key. Thanks a million! (I didn't even know there was such a thing as a secondary air injection system until I got a code...)
I might be wrong, but you should NOT use carb cleaner on plastic. (Assuming your PCV valve is plastic, mine is)
I want more video with the envoy because I find what you point out on it to be useful for me to know
Thanks for sharing your findings.
I am guessing this happens to several GM models?
I must buy for preventive maintenance
This was mad helpful. Thank you.
Thanks!
Thank you!! 🤙👍👍
I had the same issue on my 05 when I had it. I just had mine tuned out when I had my pcm tuned.

I'm SO glad my '04 Chevy Trailblazer does not have the SAIS!
Wait the 04s didn't do
Have this system???
@@fargeeks No they don't. I believe '05 was the first year for it.

Did the pump continue doing the jet sound after replacing the valve?

An Audi dealership charged me about $600 some years ago for a secondary air pump code.
Thank you!! Haven’t checked what it would cost but I’m sure I’ve saved many thousands of dollars over the life of each of my vehicles. 🤙

I need help sir! Where do i find a valve for 2005 toyota celica!? Please I need one.
Hey Jimmy, how much did that valve cost? Curious since you've dissected the old one?
@corey Babcock easier to ask some one. or call parts store.
2001 VW Passat 1.8T -- smog test readiness monitor would not set because secondary air control solenoid wouldn't hold vacuum
I couldnt find the link withthe parts please and thank you..
Happy we had an early model Envoy...no SAI on it.
Where is the link to Amazon for the parts please sir
I have a 2005 Chevy trailblazer that does this same EXACT thing. No engine code tho, but same exact noise when starting.
How are you liking living in Tn? I know it was a huge move and we are considering doing it ourselves.
I replaced my valve, pump, one oxygen sensor, and got the relay tested at Oreilly's. I think I will take my check valve apart to inspect it. It says the check valve is stuck open.
My VW Passat ‘10 has the same code. What can I do about it? It’s a 2.0 TSI engine.
I have 2007 Saturn, I changed pump relay and valve! And drove for 40 minutes and check engine light on 😢 again same code!

Hello Jimmy’s you have 3 cars of GMC & I would like to ask you Which model of the is the best and you much like?

My 09 TB is still runs good, your motor only gots 75,000 miles and secondary burn out 🤔
I’ve never seen or heard of this particular valve. It looks similar to an idle air control valve. Is that basically what it is?
No. It is a secondary air pump valve. The big hose is connected to a air injection pump (fan). When the valve opens it lets the air into the exhaust manifold to burn any unburnt fuel that enters the exhaust system.
