2008 Impala No start Hard start 5v ref

[@andrewk778]

I learned about you as a voice in the background of an Ivan video. I instantly saw you were brilliant. I subscribed when you had no videos and thirty subscribers. I have never been disappointed. You videos are informative, interesting, and educational. Thank you for sharing all your knowledge and experience. It is truly appreciated. I’ll swear you could scan, diagnose, and reprogram a Turboencabulator. Haha.

[@allanandrowey5219]

I found the channel the same way and am never disappointed

[@NewLevelAuto]

Thank you! Really means a lot to me

[@stevenhzoll7057]

Having a good understanding of how electric circuits and components work is very important. That allows you to work with the wiring diagram, if the system as its drawn does not make sense you must dig deeper into wiring references to find the information that will lead in the right direction. It's an unfortunate fact that most manufactures draw wiring diagrams differently and then you have information services sometimes trying to make "improvements". Schematics are like road maps, you've got to know how to read them before they can help you . Thanks for the great video Keith you keep adding some big pieces to the puzzle.

[@oldskoolfunk71]

Great diagnostics on the 5v ref my man. Knowing the schematics and voltage parameters is key in doing a thorough process of elimination and like always you make it look easy but I know from experience that it takes A LOT of study, trial and error to do what you do. Thanks for simplifying the diagnosing process for us all. Merry Christmas, have a strong, and prosperous 2019 Keith, God bless you and your family.

[@1984juant]

This guy and Ivan are some of the best diagnostisians in youtube.

These days I think Dorman has merged with General Motors ... 😁 I worked on a '11 Impala that failed inspection due to that secondary air system. I found a nuked relay, and valve (valve may have taken out the relay - not sure there). But, what a poorly engineered vehicle that was. Thing barely had 50k on the clock and I'm fixing this stuff, all while the blend door motor clicked away desperately trying to find home - take the key out, lock the doors, and it STILL clicked away! Unreal. Never seen a vehicle built as poorly as that one, and I've been around cars my whole life! Thanks for showing this one. 👍 I'd have got bitten by this, for sure! Guess it pays to look through everything. I'm my own worst enemy - I have no patience. If I slowed down a bit, I'd probably be successful MUCH SOONER. 😉

[@deespasojevic3013]

Your customers are blessed to have you work on their vehicles...

[@halopersin]

Gm is near and dear to my heart. It’s good to see oe gm diagrams. Sadly they sometimes don’t tell the whole story. Great diag Keith!

[@arthurfricchione8119]

Thanks, Keith. Yes, I watched Ivans video from sunup to sundown. Was kicking his mind but he persevered and solved the issue. Hope you had a good Christmas Artie

[@wyattoneable]

My goodness. That company sure has made a name for itself...and not in a good way. Your right, Ivan's video of that Dodge truck was awesome. Very helpful actually.

[@rrmech11]

I usually go to obd global first just to see if the vehicle has secondary air when looking at monitor status. Surprised the car started with the ckp unplugged. Excellent stuff. Many things I've seen on gms to go to reduced power mode. I had dirty throttle body's do this. Tps throttle angle outta whack. Excellent Video my friend.

[@1970chevelle396]

I like that Scanner. Looks like good quality.

[@billyyoder8171]

Thank you Keith. Good job. Appreciate you very much. Have a blessed and safe week.

The Mac version of the Bosch has a steering wheel holder. Great video 👍🏼

[@acinvention1150]

I hope your charging at least $150.00 an hour. Your better than any traveling dealership tech. Pretty impressive.

[@armandonika]

acinvention1 agree, the speed he diagnoses is just breathtaking!!!

[@bigfootemobileauto9734]

Now not to take anything away from Kieth but he’s done hundreds of these and he’s partially or at least halfway through before he starts videotaping on most of them! ... Wish I had the experience and patience that he has!

[@armandonika]

BigFoote Mobile Auto hello Sir in this case you are right, but he diagnoses up to 31 cars per day,usually 22-24, of course it has his experience but there are other guys more experienced but that take more time to diagnose a car, and that happens because the lack of knowledge!!

[@bigfootemobileauto9734]

That is incredible on the average of 20 to 25 cars a day! Do you have any idea how long he’s been doing this, I guess I could ask him. It is a great benefit to have expert’s like Kieth and others teaching all this valuable information. At 60 years old though I wish I could remember better but that I know just comes with practice and experience. I really haven’t been working in the automotive field all that long but the last five years I’ve been working this mobile business and trying to have the equipment and experience needed that’s the things that I come across. Happy new year brother!

[@NewLevelAuto]

Dont forget I have the luxury of a very densely packed small island as well. But yes most diagnostic work is similar to another car done already for sure. However I do not let that sway my testing procedures , rather I let that speed them up. The filming after halfway is generally because no one wants to get dizzy as I run back and forth to the truck for equipment. Plus if I keep the videos short , people can watch at break time or lunch without having to waste much time.

Allan and Rowena oh lol it's Dorman's logo, very appropriate 😆 lookup dorman products, just don't buy from them

[@allanandrowey5219]

Ah. Makes sense thank you. I have just started seeing dorman products advertised here in new Zealand.

[@jgeorges3061]

Keith, thanks for what you do by showing us all the good and excellent info how and what to look for in those situations to fix the car. Happy new year to u and urs and may 2019 be filled with more success. cheeeeeeers

[@PineHollowAutoDiagnostics]

Ah those tricky wiring diagrams...Thanks for the shout out Keith!! "Wallet with wings" lmao!

[@charliemagoo7943]

I just checked the genuine gm service info. On the 5v and low ref bussing it shows air pump solenoid on 5v2. Im still sticking with my comment to ivan that gm has good diagrams. It would have been nicer on the older stuff to see the bussing in the pcm like the 12v on cam and crank tied together on silverados

[@josephwash109]

I've always found GM wiring diagrams to be the best out there as well (but maybe I'm biased because I grew up with GM products). As long as you're in the know with GM's Regular Production Option codes, they won't steer you wrong. People unfamiliar with GM speak can easily get lost, however, if they don't notice a section of wiring diagram that says "w/ NU3". I also like how GM diagrams sometimes show sections of the internal circuitry inside of an electronic module so you can better understand the circuit as a whole.

[@NewLevelAuto]

No doubt about it fellas , the diagrams are good. The point made here is to never just read bits and pieces. Give the entire powertrain system an overlook . Especially if something doesn't seem to jive.

[@bigfootemobileauto9734]

Of the service information and diagram companies Kieth which one would you say is on top above the others? I know they each have their own little perks but I’m trying out Alldata at this time and I was subscribed to Identifix for quite a while.

[@roadkill5333]

A steering wheel holder?? What the heck Keith? Why do you want a truck driver to hold the scanner for you??

[@jeremyanthony9300]

Keith I hope you rocko and your family had a merry Christmas, and I wish you all happy and successful 2019.

[@josephwash109]

Once you were explaining the issue with the 5V reference, I started thinking automatically, "I bet it has a Dorman sensor somewhere." Seriously, when a company makes absolute junk, how does it stay in business? Wouldn't it be nice if parts stores started refusing to sell Dorman parts?

[@ahwee77329]

If they dont sell junk,we would all go home hungry.

I guess the Viso scope is pretty good since you are still using it. I've thought about getting one

[@NewLevelAuto]

No complaints, just have to learn the limitations as I go along . Also learning a few things I wasn't aware of even in Pico

[@gmsonly5087]

Nice Find! This is a case of Alldata not regurgitating factory information correctly. Do you have access to GM SI? If you do pull up Document ID: 1888866. The factory schematic shows the Secondary Air Injection (AIR) Pump Solenoid on 5V2, connector X2 terminal 1 with all the other circuits for 5V1 & 5V2. I guess you can point Alldata in that direction and they should correct it. Regardless, a nice find given the incorrect information you were given.

[@mikechiodetti6737]

I saw you using the Bosch ADS 325. How does that compare to the Snap On Verus and the Autel? Does the Bosch have scope/graphing capabilities like the Snap On? Or the Autel? I'm looking at the Bosch ADS 625, but the 325 would be a comparison start. Great Diagnostic Video! You'd think GM would learn their lesson regarding the +5 Volt outputs and put the sensors with the least amount of trouble on the same reference, and the more troublesome on a different +5Volt reference. Hence, less chances of a "leaving-you-stranded" NO START!

[@nuegodzkamara4054]

[@randyhughes5160]

I am glad to see you show the same things but how did you track it down to the same 5 volt problem

[@NewLevelAuto]

I simply started looking to make sure there were no other 5v outputs that could have been related outside the diagram. Believe none of what you read and only half what you see kinda mentality. I never trust till I know enough

[@Airman..]

Not in company's defense at all.. but the DTC description for P0641 or P0651 has this information already

[@RJMaker]

It's no wonder why sometimes good technicians struggle getting the correct diagnosis, the service litt. can be absolutely horrible.

[@daveyio87]

Anytime i get a 5 volt reference code on a gm with sai i check to see if it has a dorman valve on it haha. they should comment on this video because if they built quality parts like they say they do we would never see this problem in the field!

yes ivan needs to look at more wiring diagrams instead of free stuff . pay for your information at multiple sources.

you can get identifix right now for 140 a month that is less than 2 hours of diag time , right

[@ahill007ny]

[@mbarry9737]

I'm convinced Dorman is funded by Chinese auto makers/govt to make junk produced there; but moreover to catalogue as much data on parts made by various auto manufacturers, to use when designing new Chinese vehicles.

[@jasonmcnamara2079]

could someone explain what this air pump solenoid / wallet with wings does and why it was a problem? thanks

[@NewLevelAuto]

It was pulling the 5 volt reference circuit to ground . The air pump solenoid as they call it is a diverter that opens and allows forces air from air pump to enter exhaust stream. Works like a bellows on a woodstove if you will. Pumping air to heat the catalytic converter up to temperature faster .

[@jasonmcnamara2079]

@@NewLevelAuto thanks for quick reply and explanation. So you could actually just leave it disconnected or would the money light be on and would it not pass your emissions? ( we dont have emissions testing here in Oz yet thankfully ). I also take it there was an insulation breakdown inside the component to pull the 5V to ground? Still wrapping my head around this stuff. Like a puzzle to be solved.

[@adamtrombino106]

The thing I like about Ivan is he looks at things at a basic level, how is this thing supposed to work, and dives in from there. And he's not afraid of anything, even non automotive relative. And he listens to learn! He and I have shared talks via KZbin on older non obd2 cars for a fix, while he has schooled me on the newer stuff that I rarely see, but am interested in. Like you Keith, he is top notch and leaves his ego at home. Like any tech with integrity, his goal is to get the car fixed right the 1st time, and if it does come back, eat it, then fix it. Love his vids, and love yours too, Keith. There's always something to learn!

[@stevieg_306]
