@@robinsonsauto despite 2 years had passed by now i have used your video to solve my car check engine light much of a thank. please if you can send me the wiring diagrams I would be grateful
The videos are always worth it no matter how simple the fix because we get to see the proper thought process of how to troubleshoot a problem. You even took the time to show people that don't have bidirectional controls how to troubleshoot all three relays or components.
I really don't hardly make any comments, but this was one of the most thorough, professional troubleshooting videos I have seen. It's interesting to hear you say, "could it really be that easy," as you literally tracked down every single possible source of the code, and then continued to address problems after you found the most likely source. I really appreciate you sharing your knowledge. I just wish I had a professional scan tool like that. Thank you for the video.
I chased the same intermittent code on my '05 Chevy Trailblazer. About twice a year this code would set. All the fuses, relays, air pump and wiring checked out ok. I couldn't reproduce the problem. After two years of chasing this code, I discovered the solenoid was sticking. It would work 97% of the time. I replaced it with an AC/Delco part and haven't had any more problems.
This video was extremely valuable to me (and I’m sure others), please continue to post more like these! I really enjoyed how you took the time to show and explain the wiring schematics and how certain things could be tested with or without a bidirectional scan tool. I very much appreciate how you took the time to show the live data and explain what we should be looking at, I just bought myself my first bidirectional scanner and as a novice DIY’er I have a hard time understanding all the live data that it gives me… Also, where can a DIY’er get the explanation that you showed us on your screen of how the secondary air system operates, that too was extremely helpful. Thanks again
Great video Will!! Don't question whether or not to post a video. Someone replaced a lot of parts without fixing anything... your information / video(s) will be of help to people! Very thorough as always! Wow... Das Kaput Relay!!!
So cool I found this video.. It's exactly what I had to repair todsy but my plug end was pinched and both red wires were severed. After repairing the wire the pump came right on when I started it and I hadn't heard it before.. it was all fixed before I saw this but it helped me confirm it all.
I have this new part and will change soon , this video best ive seen , great step by step and love how you showed everyone the electrical , and trouble shooting
Great video, I appreciate the step by step, my sons truck just set that code, and now I have a great starting point. Thanks it’s about time I found a guy who actually knows how to get in depth in communicating how; what & why. Keep,up the great videos. I will continue watch them.
Excellent system description, love the way you show various methods depending on tools at hand. Gotta think the previous tech proved the pump was bad by directly powering it, then didn't remember to check the relay as well. Two problems, both caused by corrosion in a vulnerable spot.
Way above my paycheck level but it was awesome to watch you troubleshot this system this way, wow is all I can say, and thank you for posting this "extremely valuable " knowledge.
Dude you're awesome. I sincerely appreciate you and people like you who are willing to share knowledge. You probably can't imagine how many people appreciate your advice. Thank you so much. (Marvin Mac)
Thank you for this video. When I checked out the relay next to my pump I found that some AH mech unplugged it thinking they had a suckered. I cleaned up the contacts plugged it back in and so far seems fine.
I smiled when you found the fix. I appreciate the explanation of the process if you didn't have a scan tool and the visual of the O2's working as they should. Oh yeah, that relay was spanked. Great video Will!

@@robinsonsauto Retirement has been something to get use to. It's been weird but I am enjoying the time off for projects around the house. Thanks for asking.
Hell yeah, this video was worth putting out there. I have a 2005 trailblazer with a 410 code and what you just showed me was amazing Thank you so much.
GREAT VIDEO, I liked how you explained every detail and how to check it without the bidirectional scan tool, best video I've seen keep up the AWESOME JOB...
Great Video, and of course it's worth uploading. Just think of whoever replaced all that parts on the car, it reminds us there is a lot of demand for these kind of video's. Glad to see you uploading again, i always enjoy your video's👍
Welcome back Will! Glad you were able to track down that faulty relay...feel bad for the guy who fired the parts cannon at that thing and missed the target though.

this is great information thank you. but for the people that dont have a fancy dancy controler like you have, are there other ways to trigger these parts? how much did your check/controler cost you?
gonz garr thank you!! Glad to be back with you all!! Missed this part more than anything!! Getting to interact with everyone! It’s Very motivating to me..
Thank you! I will try picking back up, life events had me side tracked for a little. I have truly missed this, then when I read feedback like this it reminds me why~ motivational, thank you again
Thanks ..great explanation My 04 envoy pullin 410 code ..its derivable BUT after warm up engine looses a lot of Power for a few seconds to maybe a min - 2 then it runs like an scalded dog Again & them repeats over & Over ..so gota figuar out it its an Bad O2 upstream o2 down stream or replay or pump itself or Check Valve on engine ..thanks alot ..give me an good start to get my daily driver back up ti normal
I missed ya big guy. I think the evidence of rust and corrosion proves water intrusion. Sounds like others shot the parts cannon here but, you being a gentlemen, did not point fingers. Thanks for sharing Will, puts a different perspective on trouble shooting. I suppose everything could have been tested using a power probe. Maybe next time you can troubleshoot it the hard way, using test lights, then prove it with the scanner. Lol. Just a suggestion.
great diagnostic routine if you have time. in a busy shop, when you see a new computer, new air control valve and new pump, you should go straight for the relay, disconnect it and check the terminals if you don't see any corrosion. spending 30 minutes on-camera alone makes me think that those new parts were most likely replaced by the same person here.
Thanks for the info. My 2005 GMC Envoy has the same engine as the Trail Blazer. Very informative, but my vehicle gives the code while driving. Any ideas?
I have a 08 Chevy impala charged both air pumps and the a new code popped up.. P2440 Current DTC 1/1 Secondary_Air Injection System Switching Valve Stuck Open Bank 1
The secondary air injector in my 2004 trailblazer has been changed out three times. I was gonna go back and get it changed again and then the mechanics tried to talk me into looking at an electrical problem. Now that I watch this video, I only have to figure out one thing how to get my trailblazer up high enough to get underneath it to get that Piece out and check it.
Great step by step troubleshooting video! I learned a lot from this. Thank you for posting it. I will use your tips of troubleshooting and try to fix problem code P0410 in my 2002 Oldsmobile silhouette this Friday.
Thank you for that informative great video Will! So the secondary air injection pump is just for testing the 02 sensors? Is there any other use for it? & Yes your video was very informative and helpful. I like the way you explain things and give other useful information...I see you’ve learned well from the other masters! great job. Thanks, Doug.
Hi Doug. The purpose of the secondary air injection system is to help reduce hydrocarbon emissions during cold start. During cold start, the fuel system control is in open loop for a few seconds. The fuel air mixture will be rich because the ECM will not be fine tuning the fuel control (trims). The secondary air injection will allow added air (oxygen) into the exhaust stream to mix with the extra fuel in the exhaust (that did not burn in the cylinders). This will give the catalytic converter(s) enough air to allow the extra fuel to create the catalytic effect which will allow the catalytic converter(s) to heat up quicker. This will help lower the emissions quicker/sooner. The testing procedure he is describing in the video is how the ECM/PCM does a self test of the secondary air injection system. During closed loop, the oxygen sensors are signalling normally and the fuel system is controlled by the ECM/PCM (trims). If the secondary air injection system is working properly, the ECM/PCM expects to see the oxygen sensors voltage drop (go lean) when extra air is pumped straight into the exhaust stream. Note, if the vehicle is equipped with AFR sensors instead of oxygen sensors, the AFR sensors voltage will go up when the extra oxygen leans the exhaust stream. Hope this helps.
@@robinsonsauto thank you Will for everything you do for the community. You and many others are a blessing to multitudes around the world. Have a blessed and safe week.
Billy Yoder Yes thanks for that Billy, and as I understand it the AFR sensors voltage goes up and regular oxygen sensors is the opposite, voltage goes down or am I thinking of amperage on those? Just brushing up my knowledgeable information that I need to know. Thanks again, Doug
@@bigfootemobileauto9734 hi Doug. You are correct. Regular narrow band oxygen sensors voltage goes down when lean, up when rich. Wide band (A/F ratio) sensor data will show voltage or amperage (or display both) doing the opposite.
Hi, I was wondering if that bad relay also activates the solenoid that the air pump is connected to? My air pump is working but the new solenoid I put on is not opening/clicking, like it's not getting any power.
I think the system description (approx. 2:30) is incorrect. It seems to be mistaking the pump OFF decreasing voltage result as the normal ON result. Instead, it should describe the result you got as the indication of a normally functioning system. What do you think? Also, the description of the system itself is not very clear and so I would suspect it is also not correct.
Could this cause it to rough idle and stall with heat and ac on? I don’t think it will but I only have this code and I can’t use my ac or heat without it instantly stalling on me. I have done the following, cleaned out the throttle body, changed fuel filter, spark plugs and coil packs, evap system. Stumped. I don’t have any other codes except this one
Hello, If you don't have a $2000 scan tool, and your trailblazer doesn't stay at a constant rpm while driving, without codes, what would you replace first? sorry for the dumb question. TIA!
Even when you think it may not be valuable to you, its always valuable to that one person who really needs it. Thanks for posting.
