P0410 Chevrolet Trailblazer Secondary Air Injection Check Valve and pump replacement

Secondary Air Injection Check Valve, and Air Pump replacement procedure done on a 2005 Trailblazer

[@jeffscott3160]

I don't know how they get away with using this technology still. It does nothing to reduce the amount of overall NOx the engine produces. It simply adds fresh are to the exhaust to fool sniffing equipment into thinking there is "cleaner" exhaust being produced by the engine. The engine is producing the same exhaust with or without this system.

[@dollfacedkilla693]

So could I essentially unplug a failing one and not use it until I have the money to replace it in the future? Cause I think mines causing my car to lose power and stall when idling.

Thank God for Putty Knives

[@1RoadGarage]

What was the other code?

[@bbbjim1fixedit]

I am sorry to say I do not remember, yet I wish you the best on your repair

[@fredwatson383]

The replacement air pump sounded like a jet engine during engine startup. It failed after a couple of weeks. Cheap Chinese Crap is going to be the death of us all.

[@bbbjim1fixedit]

much agreed

[@ProjectCarTV]

nice

[@bbbjim1fixedit]

Thanks

[@angelf9800]

I have code p0411 on my trailblazer what part should I replace first.

[@bbbjim1fixedit]

you may wish to look closer at your vacuum hoses for cracks. I wish you the best on your repair

[@repoman1017]

My trailblazer is sluggish 410 code. It isn’t missing did you have the same system?

[@bbbjim1fixedit]

You may wish to take a closer look at the hoses for cracks giving you a vacuum leak. I wish you the best on your repair

This help me quite a bit thanks for all the information guys I really thought this is gonna be a lot harder than I figured but this seems to make it pretty clear that even I can do it thanks again

[@bbbjim1fixedit]

Glad to hear it was helpful

[@joselupavon5515]

thanks for ur efforts

[@PresentedByBailey]

i missed where you described why you were doing the solenoid after you did the smog pump. maybe i fast forward past the explanation.

[@bbbjim1fixedit]

the hoses going to the smog pump were full of water, so we tested the solenoid

[@craigmcdowell8654]

Very helpful guys! Thank you very much

[@bbbjim1fixedit]

Glad to hear you found this helpful

[@shadeshiest22]

Do you disconnect the battery first before removing anything??

[@bbbjim1fixedit]

yes, and I place a rag over the end of the cable so it doesn't accidently reconnect.

[@kevinleon7772]

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!

[@bbbjim1fixedit]

if the hose itself broke you maybe able to get a heater hose the same size. if where it attaches broke off you may wish to consider super glue and sprinkle baking soda on it. I wish you the best

[@5052awhite]

I know this is a old video but i have a 04 Trailblazer ls and just got this code....where is this pump located i looked all under the hood and found nothing that looks like this pump

[@bbbjim1fixedit]

under the vehicle, driver side middle, I wish you the best on your repair

[@Stars-us4gh]

I am actually doing this air pump today already did the one under the hood , great vid thank you👍

[@bbbjim1fixedit]

Glad it helped

[@jessetruman5788]

I'm finding these pumps on Amazon for 40$ but at auto zone for 300$ any difference in the two?

[@bbbjim1fixedit]

Many of the internet copies are not very powerful thus may not be worth installing. You may wish to look at Rockauto. They may have better prices than AZ. I wish you the best on your repair

[@BitterCarGuy]

Good video, do you have the part numbers for the replacement parts??

[@bbbjim1fixedit]

sorry, it's been a few years since this video was made. Rockauto.com is a good source for parts. I wish you the best on your repair

[@bandittweintraub]

you uh.. lost.. uh.. audio there for uh... a moment. but uh.. otherwise uh.. informative uh.. video uh.. you got there.

[@fredwatson383]

We all have our quirks. A trained voice over person would probably be clueless under the hood of any car, so I'll over look the lack of voice training here.

[@jeffs6418]

Question I replaced the air valve with a AC Delco one, but when I reconnected the black hose it does not fit over the port however it did snap in place. Should the black hose fit over the port cuz mine will not?

[@bbbjim1fixedit]

After the hose connection snaps in place it is on

[@tylersanders8853]

can this happen and it not throw an engine code?

[@bbbjim1fixedit]

I think that it would be unlikely that it would not throw a code if your air pump was not working correctly. Yet I wish you the best on your repair

[@joeysanchez2657]

How do you disconnect the electrical connection

[@bbbjim1fixedit]

I believe the colored locking tab needs to be pulled back first

[@hoo33u]

How did you get the hoses loose from the clamps on the pump they are not supposed to be a separate piece they come built into the house

[@bbbjim1fixedit]

The hoses just pull off, you may have to twist them if they are stuck. I wish you the best on your repair

[@hoo33u]

@@bbbjim1fixedit but they aren't supposed to. How did you keep the houses from pulling loose?

[@bbbjim1fixedit]

@@hoo33u The hoses you have maybe have hardened over time and lost the elasticity need to keep them on

[@tajnile5024]

what size/kind of bolt is that for the check valve?

[@bbbjim1fixedit]

The trans dip stick tube is 10mm and the valve is 13mm

[@kingnasty5381]

At the bottom right of the smog pump what is that big relay looking thing grey in color. Mine is burnt out or corroded need to replace

[@bbbjim1fixedit]

I'm sorry to say this isn't my vehicle and it isn't here for me to look at, hopefully someone will read your comment that knows what it is and let you know soon. Best of luck on your repair

Air Pump replacement -where did u buy it and what brand? Secondary Air Injection Check Valve-where did you but it and what brand? i looked on amazon and saw negative reviews about the air pump -was wondering if it is the same and did you have problems?

[@bbbjim1fixedit]

My son purchased the parts I believe from AutoZone, both of which were made in China

[@JS-nk4re]

Check the hose coming off secondary air pump going under manifold cover running along firewall before you buy anything.

[@universalflow6000]

J S why do I need to check before buying

[@JS-nk4re]

I replaced all my system and it was just the 1/4 hose keeping check engine light on changed hose light went off as soon as truck warmed up.

What's trick to remove power to top unit

[@bbbjim1fixedit]

a tab on the connection locks it in place, I can not remember which type these use, however most locks have a tab to depress to unlock them

[@nicholass7188]

Press the center of the green tab on the plug, then pull it back, once pulled back, squeeze on the top and bottom of the plug and pull it out.. Hope this helps someone

[@jorgejimenez4829]

Does the 03 trailblazer have this pump?

[@bbbjim1fixedit]

I am not sure, if the V8 engine uses this system; if you have the 6 cylinder the smog pump would be located on the drivers side mid way back under the vehicle if it does have one for your year.

[@MyGunzBurst]

I’ve got a 2007 Saab 97X 4.2L and got the same error code. The vehicle is made by GM and your motor looks the same as mine. How did you reset the error code after replacing parts?

[@sebastianroher]

@@MyGunzBurst any scan tool with the ability to read and erase codes will do the job, also disconnecting battery terminals will do the trick ;)

[@oibal60]

Thanks for this.

[@mileswatkins6472]

This is very vauge The black box is the pump The silver part ( by the intake manifold ) is the check valve And the hoses = equals whole entire secendary air system ?

[@bbbjim1fixedit]

yes that is all of it

[@donmiller2977]

Is this a 2 pin or a 5 pin air solenoid value. If 5 where did you do the testing? I can't see that part of the video.

[@bbbjim1fixedit]

the one in this video was 2 wire, not sure how to test a 5 wire, yet I wish you the best on your repair
