I pray this works. Thank you! I’ve replaced the MAP sensor and O2 sensor already and still getting same code! Was told this would help.

I got codes P0411 on my 2008 envoy sle and it says to replace secondary air injection pump and secondary air injection check valve. Ima try this first then see what happens

This is such an awesome explanation. Great video! Life saver!

If there is a lot of sludge from an oil leak, do you need to spray anything in there to clean it out?

[@mahoganyslay5767]

Thank you sooo much!! As a female, I prefer to do this myself

Do you know what the hose that you remove at 1:08 is? I have one that I can’t figure out where it goes to. When I removed the air filter casing, it was not connected to anything.

If the part is bad on the vechical how would the car sound or fill I have a 2006 Chevrolet trail blazer?

[@eddiecard]

You sound like Edward Norton…. Great video thank you!

I did this but my Envoy is still throwing code P2440. Everything I look up says to replace this check valve but not what to do if it doesn't fix the problem.

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!

I like the videos at the beginning when you say the tools you need so I know which to grab

On My 2005 Chevy trailblazer, when I start it the pump itself sound like a vacuum cleaner for about 40 seconds and then stops. Could this be because of that check valve? Or should I replace both the check valve and the secondary air pump. Either way, I’ll probably end up doing both! No engine codes either. Just vacuum cleaner noise upon startup. Thanks in advance!!

mine is a 06 and it has a different plug, not a 2pin one. How come?

[@fernesal]

How to know if we need to replace it?

[@loulewis2306]

Hello how are you?

[@stephensmith3080]

Can't get bolts to tighten

[@Md9096cptudc]

Hope this works I'm at the mechanic shop right now and their charging me $550 to replace this I'm going to do it myself hopefully I can get it done

I have to say one thing that's stock oem air cleaner is garbage it doesn't filter all your air I recommend investing in a performance air intake system because the performance air Intake system will filter all your incoming air than the stock one I've work at a junk yard for 5 years and they been selling those trailblazer to the junk yard
