Thanks, been awhile since I have done one of these...soon as I diagnose them, I don't ever get to fix them anymore...lol...life of a diagnostic technician I suppose 🤣
Stumbling across this as I'm actually looking to replace the exhaust manifold but came across my engine having what I'm finding out are these...secondary air injectors. It made the task a bit more complicated than I'd hoped after watching other videos regarding manifold replacement. Question...are all of these bolts for the "runners" easily accessible? Upon a quick inspection of the engine and when I found out these were in my way I was able to see/feel for maybe 2. This wasn't very in depth but it appeared this was going to be quite the chore getting these off and out of the way to get to the manifold (I think I've read a few comments in some message board/forums also stating that he was seemingly unable to get to find all of the bolts holding the runners on the header).
@@PaulysAuto Don't expect you to see this and this is again a bit of an aside to what your video is about but there just isn't much out there on doing this for the layman. So here goes: what exactly is one do with getting the aluminum piping that the SAI rubber piping connects to that brings in the air (and rests "beside" the runners and on top of the heat shield/exhaust manifold.). This thing is likely killing my DIY ex. manifold replacement! I just found where get the remaining 4 bolts to the runners (under the heat shield, of course) but to proceed any further, that piping is clearly in the way and of course comes all the way from the lower front of the engine.

Currently in the middle of replacing an engine in one and the replacement I got had these holes but the car itself didn’t have the modules . Am I able to block them off or should I just change the heads
i have a 2010 malibu 2.4l it had a secondary injection on it i just replaced the motor with an 08 malibu motor that didnt have the secondary injection on it i hooked everything up except the rail on to the back above exhaust manifold now i have a p0411 can the sai be removed from the computer from the dealer ?
I have a 2006 chevy trailblazer keep failing emission this the only code that comes up P0411 even the Chevy dealer can’t tell me why I keep having this code after everything has already been replaced!
Question I got the P0411 code... i replaced the pump but the original pump is actually good. So that was useless. I dont want to keep buying parts if they arent bad. What should be the next step? Valves? Solenoids? How can I pinpoint it?
Fantastic video but way more than the average Joe like me can do. I still have the p0411 code and think this is the issue. I had the TBS done by the dealer though and I'm now at 155k miles. Shouldn't they still cover it?
It all depends on how well they cleaned the ports out...you may have a weak pump due to them being plugged. As far as, what they will cover under warranty, I couldn't tell you my friend.
Hello Pauly. Great, informative video! May I ask the name and make of that fancy diagnostic tool you're using to diagnose this problem? Every mechanic should own one of those!
@@PaulysAuto Thank you for your response. That is quite the diagnostic tool! The way you can control/test various systems in the vehicle through it is amazing! My friend is a mechanic and I bet he'd love to have a tool like that. I sent him your video here because my 2013 Equinox 2.4L has the same issue that your video addresses. In addition to cleaning out the carbon clogs on my CA 2.4L (Imagine the carbon after 209K miles...), it also needed both secondary air valves @ $300 a pop. 😮💨 They looked nasty! He's now trying to diagnose a VVT solenoid issue on the vehicle and I bet the Zeus would be of great benefit. Thanks again for the great video!
Think about that DTC long and hard, do as much research as possible, you need to clear out those ports in that head you also need to pay attention to other comments on this video 🥰😇😉 Watch it several times and listen to what I'm saying. This channel was to get you on the right path. To develop, grow, and expand... Not to just give you the answer even though I did.
@@PaulysAuto okay whats the difference between. a air smog pump and a air smog check valve. I have 2 black hoses that needs to be connected to something. my mechanic said my cylinder head didn't have smog ports he by pass it somehow took both air smog pumps off now I have the right head but don't know what parts goes to the 2 black hoses
@@blesdavis7637 If the vehicle has California missions it needs the correct head which will have ports for the the 2 pipes that go to your air injection solenoids for the Air injection flow to occur. The Air pump just pumps the air to the solenoids and when Air injection is required on initial startup the ECM commands the Air injection pump and solenoids on to send air into the exhaust to help speed up the catalyst process for closed loop fuel control.
Uy veh. Yet another reason I don't like my wife's 2013 Equinoxious. We've had the P0411 for about a year now, I know the pump works and the hoses are clear. Has to pass e-check next year. Between this problem, the chronic oil burning, and the rusting doors, it's been quite a cursed little car.
Hmmm...my 2013 doesn't have this secondary system. It must be a California emissions thing. I recently rebuilt my 2.4 and wonder why some do and don't have certain things.
@@PaulysAuto This is actually an incorrect statement. Even if he stayed up on oil changes and watching your live streams, it would not help him. It's a know fact and there was even a class-action lawsuit that some of the 2013 Equinox's got some bad motors that the rings go bad and burn lots of oil. My girlfriend has one, and it would burn a quart of oil every 450 miles. The rings are so bad, you can hold your finger over the vent tube on the valve cover, and it'll build enough pressure, that when you let go, it's like a turbo blow-off valve going off. lol. Also, with some these burning oil that bad, and say the cat gets clogged, could the pressure above the cat in the exhaust system be a cause for this code? Like not letting the solnoids pump the air in becuase the pump doesn't have enough pressure to fight with the build up of pressure because of the clogged cat?
@@MagnumChris Eventually you have to re-ring any engine with emissions like this and let's just be honest, the 2.4L is a gravy engine to re-ring. You can soak the d*** rings and slow the oil burning down or you can just bite the bullet and slam the pistons out the bottom and get it done. And I still think and I will still hold up to this, people do not change their oil enough nor do they even check it frequently - that's a straight fact.
@@MagnumChris GM Engine Top Tier does amazing things - Which is what's recommended to clean these ports on these heads with these California emissions when they get plugged up with all the crap thanks to California's ridiculous standards!
Awesome video just helped me out a lot but the customer came back a few weeks later and it says secondary air injection low voltage but I checked and seems fine so I'm lost again.
I can not get those air cross over bolts out.. im stuck on the two lowest bolts between the manifold.. any tips on what you used or how you got to them
I tried 1/4 inch.. I believe I have the wobbly.. but I mean the nut seems straight and the angle just seems all wrong. I appreciate the feed back. I wish some would make a video of removing those. I do appreciate the feed back
I had to actually take the manifold off to get mine out which i had to do anyways in order to in clog the holes in the back of the block where the manifold gasket goes
@@PaulysAuto solonoids. Theres a unique clicking or ticking coming from the back front side of my engine i cant identify. I dont knoe if maybe the solenoids might click a bunch when the ports are clogged. Even when unolugged. In my head it makes sense because that pressure has to go somewheee. It stops clicking when warm too
@@captainsledge7554 put your hand on them and feel for synchronization to your sound. You sure it isn't your chain smacking on the upper guide that may be wasted?
iDK TBH ..Might help to drain and vacuum fill cooling system every 70k and replace T-STAT to ensure warm up time is adequate. Also good warm-up's on cold start even during warm weather...
@@abduliscool74 Plugs? There are no plugs...the ports get clogged with carbon which prevents the Air Injection Pump from pushing fresh air into the Exhaust on cold startup; which helps expedite the Catalyst process in the Converter and push the system into closed loop fuel control faster...California Emissions System only the Federal Emissions 2.4L doesn't have any of this.
For anyone having this problem I was having same problem after all the video's I tried hooking shop vac up to the hose that goes into breather box from secondary air motor suction hose and I reversed and blew air into it next day light is off been off all day
Not as far as I know, maybe a special coverage depending on circumstances, but this was actually a published Technical Service Bulletin. Depending upon your purchased warranty, it's one of those things that may or may not be covered. You should consult your local dealer and see, I don't want to give out poor information on this.
STOP STOP STOP Would you please clarify if this stupid air injection system is ONLY ON CALIFORNIA CARS . I am in missouri and my 2015 equinox 2.4 ecotec does not appear to have this system. THANK YOU FOR YOUR GOOD WORK AND GOOD HEALTH TO YOU IN THE NEW YEAR
California Emissions only...you'll know if it's got it by looking behind the Cylinder Head toward the firewall and Exhaust Manifold....you will see this setup.
I'm curious, what exactly this comment implies? I mean I have showed you the process numerous times. You must mean that I didn't give you a answer you were looking for.

Hey there I have a question about the valve air injection What’s side is bank #1? Passenger or driver side?
My check engine light went on and the scanner gave me this code: P2440 and it says “secondary Air injection system switching valve stuck open (bank 1)
It's a 4 cylinder the 4 cylinders are bank 1 there's no bank 2 because it's an inline 4 cylinder monitoring all 4 cylinders with one upstream O2.
Bank 1 Air valve is on the driver's side.
Does cleaning it work or does the air injection need to be replaced? I replaced the cat and manifold already.

@@PaulysAuto Thank you for the response,it turned out that it was...Cleaning of the secondary injection ports and replacement of the pump👍
STOP STOP STOP Would you please clarify if this stupid air injection system is ONLY ON CALIFORNIA CARS . I am in missouri and my 2015 equinox 2.4 ecotec does not appear to have this system. THANK YOU FOR YOUR GOOD WORK AND GOOD HEALTH TO YOU IN THE NEW YEAR
California Emissions only...you'll know if it's got it by looking behind the Cylinder Head toward the firewall and Exhaust Manifold....you will see this setup.
I don't know the cost but I'm gone find out today P0411 code 15 GMC terrain ohh boy with only 43,000 miles smh
I feel your frustration and I do not disagree
Needed two air valves and something else they said went to the GMC dealer each valve 400 but my warranty covered it I only have to pay 200
@@Emmanuel-zr8cl This is good to hear at least You got a deal on All of It
Gm should be paying for this cleaning for a bad design
Wouldn't that be wonderful? That's why I don't own CA emissions vehicles.
They do! Special policy. 10 years or 150k miles I believe
@@440-6pakroadrunner 🧐🧐🧐 I took mine in the other week and they quoted me a pretty penny. 2013 with 91k miles
Yes, depending on what you paid for warranty ofcourse 😉
It's not ideal, but these engines are solid if you take care of them. 3k on oil changes is VERY IMPORTANT
you dont show your work
I'm curious, what exactly this comment implies? I mean I have showed you the process numerous times.
You must mean that I didn't give you a answer you were looking for.
