Chevy Fuel Trim Imbalance Codes
Vložit
- čas přidán 12. 04. 2024
- In this video I bring you along as I have a look at a customer's 2013 Chevy Silverado with the big 5.3 that has codes P219B and P219A. These are fuel trim imbalance codes (cylinder to cylinder fuel imbalance.) These codes can be really tricky to point at something tangible and make a call on a faulty part. In this video I discuss some of things I look for on these vehicles when faced with these codes.

It has been about a month and a half since I fixed this vehicle, and the guy is happy as a clam. No engine light, drive cycle complete, passed emissions inspection and fuel mileage back to what it should be. Hope there was some useful tidbits in this video to help you on your diagnostic path.

As you said, it would have been interesting seeing the O2 graphs with the aftermarket sensors. I just like your format of 20 - 30 minutes videos.
Very interesting, my Gmail dealer offers aftermarket parts
I LOVE THESE "Get Right To The Point Videos" .... I was born in 1957, Don't even own a car anymore, watching Eric fixing stuff , always teaches me something I did not already know ... Every Single Time Folks ... "Remember Folks, If I can Learn Something, You can Learn Something"
"I can't even think of something stupid to say. Mrs O would be proud of Me" 🤣
I've experienced the Dodge trucks acting funny with aftermarket O2s. I didn't realize the newer GM trucks can also do that.
How could you go to Wilbert’s without us.. we “The People” are hurt!!!😢
Please forgive me 🙏🏼
We shall… but will look away out the passenger window like a dog coming back from the vet!!

As a South African I am pleasantly surprised by learning that the USA is one of 15 countries worldwide that the Bearing Man Group is doing business in!! This group was started in 1974 as a single person business in a garage in Durban, South Africa! A great success story and Proudly South African! Thanks Eric, I enjoy all you very informative content, especially the way you presented it. Keep it up. Jan Cilliers, Clanwilliam, Western Cape.

I have found Rock Auto to be straight as to the brands they sell and selling genuine parts. They sell a range of parts from different companies so you can choose your price point. The GM brand parts are still less than at a dealer, but not the lowball prices on Amazon or eBay.
I agree
It's nice to see occasional videos like this that efficiently deal with a problem that can be difficult to pin down. Having an algorithm or checklist prevents the dreaded callback that ends up throwing mud at bystanders. Even in the DIY setting sometimes you want to just fix it and move on with the day. As you say, these kind of videos are underrepresented because everybody wants to focus on exact diagnosis.
Correct 👍
You went to Wilbert's and didn't bring us along? Great video as always.
As a random YT jabroni, I enjoy watching you go through your troubleshooting method. Your no-nonsense description of the problem and the fix is easy to follow and your sense of humor easily make you one of the best channels on this platform. Having said that, if you goto Wilburts again without us or forget to put in the sound affects when you grab the fluid film or break clean, I'm gonna riot! 😁 Have a great day Mr. O
Funny bit of info...my wife works for the post office which happens to be very close to a GM dealer. They recently started ordering A LOT of their parts through Amazon. They said they're cheaper than what THEY can buy them for through GM. That alone screams counterfeit if you ask me!
Likely violating their franchise agreement.
I was thinking when he said "go to the dealer" that why wouldn't a scum bag dealer buy cheap parts on amazon, and then you said this. UGH! can't trust anyone anymore. Sad.
It's not just the knowledge that makes this shop great, it's the honesty. Having said that, it really does start with the knowledge and that's what I love about SMA!
Learning how to diagnose fuel trim codes is critical to any diagnostic routine involving them, especially when they go lean. Thank you SMA.
I've learned something about lean codes. Once you're sure there are no vacuum leaks downstream from the MAF, the only other place unmetered air can get into the system is leaking past the intake guides. A vacuum gage can verify that for you.
K-Line makes bronze valve guide liners and tooling. I've had good luck with them. A company called Neway makes carbide valve seat and valve face cutters and tooling. I've had good luck with them, too. I've had to start doing my own valve jobs since the quality of machine shop work around here has slid into the toilet. Good luck, man.
@@LuckyBaldwin777 A lot has slid into the toilet with parts and good quality work. Take Care
Ken and Nancy air filter omg almost spit out my tea good one Mr.O
Good job Eric , a big take away for me from this video is to not over look the simple basics! For a lot of people they would not know that the broken air box lid can be a contributing problem!
These types of videos are actually very relevant to all types of car models. You covered a lot of possible causes & solutions in almost 19 minutes.
Eric has become a wise old man. His voice is an octave deeper, his beard is the colour of experience, and he's about a foot taller compared to when he first started the channel.
Except he’s not even 50 yet so he’s not old.

I learn something every time I watch this channel.
Eric is very good at teaching us, even when he's not trying-and while he's making a living doing a "dirty job".
I got O2 sensors online ONCE, they were so different I didn't even attempt to install them. The originals had different wiring and clip, I ordered GM OEM and the box said GM so I contacted the "well known" company about my problem and they tried to tell me those were "original OEM" when I pushed back and said I have pics of both they refunded the $ and told me to keep the ones they sent me. Like I said, this was a well known online parts company, I gave them the worst review I could without the salty language. I got the replacement OEM sensors at Advanced at a comparable price so "brick and mortar store everytime!!!
Thanks for your insight, I love your show.

PS. I also ordered a trans line OEM GM and got a Dorman that kept leaking at the trans side, same results. Needless to say they don't get my business. 😎
Last year my stepdaughter purchased a very nice car for her daughter, with a dirty MAF, exhaust leaks aftermarket exhaust parts, and 8 hard codes(to make it short).I replaced exhaust parts , cat back, ABS wheel sensor with a broken wire and cleaned it up for NYS inspection. Thanks to the walk thru on your diagnosis I was confident with my thought process and found aftermarket parts “Dor” were most of my issues! Keep up the good ,ride along videos, they inspire us all!

I remember that was the norm getting crappy gas among cheapo gas places. I also remember that the ready mix company I retired from that back during the '91 recession our company brass tried saving money by buying crap diesel. The trucks wouldn't run good plus our mechanics were busy changing out fuel filters.
Cleaning that MAF wire with a q-tip proves you're a braver man than me. Impressive.
Was thinking the same 😂
Watching you gently clean that MAF sensor with a q-tip was relaxing and therapeudic. Kind of like watching Bob Ross painting happy little clouds!
Happy little hot wire sensors!
The 2013/14 Tahoes I have had over the years have been plagued by those codes. I chased them for a year on one, used NTK/Denso forward 02 sensors and they kept coming back. OEM sensors fixed it.
As soon as I saw the broken air filter box, I thought for sure we were talking about a trip to Wilbert's. Then to find out you went without us. It's a sad day here at The South main Auto channel.... A said day indeed...
Really great information on those codes. I’ll never buy another GM product after watching years of SMA.
Remember Craig, SMA is a GM shop. If he did lots of Chrysler and Ford as well you might be even more horrified !
fiat/chrysler and ford have even WAY more issues!! terrible engines
Good luck finding ANY automaker in the world that doesn't have some sort of issues in their lineup 😂
Vehicle makes are irrelevant. They all break down and Honda and Toyota are starting to weaken as well.
@lvsqcsl agree! I am disappointed by the rubber trim that disintegrates on Honda and Toyota products on doors and around windshield. Those brands did much better for decades in TX. I don't see ford, gm, or ram having the same trim fall aprt like I see on Tundras.
Wouldn't mind seeing a regular series of general repairs or maintenance, etc. showing you using more standard tools/techniques that the average knucklehead is more likely to have and use in their home. Thanks for the great content and may The Good Lord continue to bless you and you family.
he does more GM cars because that's what is out there in his part of the world. They all break
Don't hesitate to record and post your diagnosis procedures, even if you think we won't be that interested.....because trust me, we WILL be. I particularly devour every 5.3 video cause I have one and want to educate myself on what to look for. Thanks for bringing us along.
Me too
Educating the consumers seems to be a big part of who you are. Thanks for the info....... price isn't always the best answer!
If I can do it, it's probably because you showed me how to do it, regardless of when you pointed. Thank you very much.

Perfectly stated. After all the other systems are checked, the est alcohol content pid should be checked. As gas prices are rising again, I've seen more and more GM's come in with too much ethanol as customers are looking for cheaper gas. 219 a and b in memory or hard fault.
I posted a comment above, what else could it be besides these issues?
these codes in these 07-13 silverados trip up alot of shops and everytime they ask me about them my answer is always pull out the aftermarket O2 sensors and put in factory. Most of them get this code after an 02 replacement for a different code.
I had P015B and P015D and changed both upstream to denso. Now months later, P219A bank 1 pops up. Change to Acdelco ?
Great video as always..
Im glad to see you stressing the importance of using OEM parts!
Dang it. Missed a trip to the junk yard. Son of a.........well. Maybe next time. Nice job Eric!!
Glad to see another Chevy repair
All that talk of top tier fuel, then that ONE gas station that would mess with a guy's truck...
I had a '66 Thunderbird. It would only run right on Exxon, Texaco or Diamond Shamrock gas (back in the day, old people unite or something...) If you fed it anything else, it would stall on some turns. If you fed it Shell specifically, it would run like crap and stall out on *every* turn. The only thing changing the operations of the car was the gasoline, I never had the carb tuned or changed in anyway. Learned to just get Exxon mostly and it was happy, so I was happy.
So... there ya go. My contribution to the 'where ya get your gas matters' conversation I suppose. :) Thanks for all you do showing us how to work on cars, Eric!
LIKED this video. Enjoy hearing your thinking. You made it very clear why this approach is the most time/cost effective one for this problem.
What Eric Said: "Injectors good, leave them. Airbox broke, lowest cost fix = used. O2 sensors sluggish, replace. Air filter new, reuse. Rule out gas in oil by doing oil change. Mass airflow is reading high, clean and reuse."
What the customer heard "Eric won't fix my truck unless I do a lot of unrelated work like an oil change and new O2 sensors and cleaning stuff that has nothing to do with my problem"
Sometimes it is also many small problems adding up and that is hard to explain to a customer. I have this car that came in with a check engine light, cold misfire and fuel trim of 44. The cleaning of the MAF, cleaning throttle body and new throttle body mounting gasket got it down to 18. Then the intake manifold gasket it got it down to 12. That's pretty difficult to explain to the customer that they still have a problem but it's a small one now and not totally fixed after you have done that much stuff. It sounds like I was just shotgunning parts at it.
@@Troy_Built There's a difference between firing the parts cannon and replacing hot button parts that are known to cause issues even when not failed. I like to replace the cummins intake/egr sensors every year or two as they regularly fail in range or don't have set fail parameters due to carbon plugging. The engine inherently trusts a MAP sensor that's 100% carbon plugged and throwing readings 20% low. Cummins doesn't agree, but they can't even manage to fix their own engines...
Imagine the customer taking the truck to the local Chevy stealer, they would have done a parts cannon , not fixed it and charged like a wounded bull.
SMA is a local treasure , support it guys.
I sport SMA colors on my back regularly. It's my favorite hoodie, have to get another one soon.
Enjoyed the video! Amen to buying electronic parts, sensors, etc. from a brick and mortar store!
There is always something of value to learn and store in your mind for later on. We all learn to not shoot the parts canon as it’s always more expensive than necessary.
A born teacher. Wise young people should apprentice themselves in your shop.
Great diagnostic and repair, Eric! Ivan had a fuel quality issue recently and adding good fuel solved most of the problems.
Another amazing video!! Your customers don't realize what a treasure they have, with your shop. Great job as always
Your videos are helping me diagnose better! Thanks
So this is what I have been missin. I thought I had patreon all set up, but I guess not. Thanks for all you do, this Bud's for you...
Much appreciated!
Yeah, I had Patreon set up as well but switched over to the YT for the perks.
Very valuable information and thought process. Thanks for sharing, I know some shops throw injectors at this problem 1st thing 🤦 Stay safe, and God bless
Hello Eric .been subscribed for a while to your channel I been a mechanic for 40 years. I wish young men would😮 step-up an learning the trade so many shops don't have young men willing learn and trade of any kind.
I learn a lot from your . Thank You for sharing your knowledge of our trade. A admired Fan. .
Thank you from

Those O2's look really nice. That engine gets to breath better.
This video was really interesting. The little things that can cause big problems with error codes.
My silverado is almost at 186000 miles. I did replace the winter's on the cylinder number 7 side the whole bank. Here's what I asked for a replaced transmission cooler lines transmission cooler. TMS sensor battery. Paul joints, that's about it, but I love driving that truck run so good and it looks so good.
I know what you mean about gasoline stations. In the 70's 80's and 90's (before a thousand computers per car) my brother was a Toyota Mechanic in the Pittsburgh area, he saw a lot of cars (Toyota, GM, Ford, and Chrysler) that ran like crap if the customer had used Gulf gasoline. They would run rough or ping, or not have the power they used to have. He told them to fill it with a tank or two of Premium and magically the problem resolved itself. I have used a LOT of gas in 70 years, but have never used a drop of Gulf because of that
Thanks Teach. Put yourself down for a extra Hr. today. Have a nice day.
The aftermarket as a whole says our product can increase power or fuel economy. I would be very interested to see a video series on what does work and what doesn’t. And why sticking to OEM is best
Eric information is king. Keep on informing us.
Excellent video! The answer is not always one part, like our minds want. In this case doing just one of the four items (Oxygen sensors, air box repair, oil change, mass air flow cleaning) may not have solved the problem but doing all four does solve it. Each contributed to the overall problem and in concert they tripped the code. Can be hard to explain.
Great video
The more detail explaining the trouble and repair the better.
Thanks for your time...
Lots o' picky little things to make stuff run crappy. Thanks for the video.
Thanks for the video Mr and Mrs O
You bet
Your videos are great. Thank you
I just love watching your process!
Interesting the damaged air box would cause high air flow readings even tho the MAF sensor is further downstream past those air leaks.
Always learn things from SMA's videos. 👍
I've had complete success with oil consumption 0n 1 and 7. Pull the plug or plugs and put cylinder in close to the bottom of the bore. Pour x66 or equivalent in and let it fester for a couple hours. Before reinstalling plug crank engine over to clear cylinder. You will get immediate improvement and results. I've used this method and have been very successful.
X66? What's that?
Thank you, Eric. Have a great weekend.
Great video! Thanks for the Top tier info.
I always learn something from your videos. THANKS
Excellent training lesson ! Thanks !!
Thank you for a great video, I am always learning new tricks from your channel.
It is fortunate that we get to watch your channel on very GM specific problems. A channel this prolific could never exist for Toyota, which I guess is fortunate for us owners. I found out recently how hard it is to get a remanufactured transmission for my 2000 4Runner, because there is little remanufacturing market for something that doesn't break. However, that means any OEM one with 100K miles on it still has a tone of life left in it, so for $1K delivered to the shop I'm back in business. It had 280K miles on it, I bought it several months ago, and the fluid was pure black. I don't when, or if, the fluid was ever changed. I'm getting one with 80K I I'm going to change the fluid every year, and see how many hundreds of thousands of miles it can last.
It does exist, the car care nut for Toyota
@@travissheehan6082 The Car Care Nut is mostly just clickbait with extremely basic information. His videos provide very little in-depth analysis and diagnosis, and generally his opinions on why certain things happen is at best superficial and at worst just wrong.
The transmission in the 2022 corolla i had failed in less than 100 miles... Toyotas break down. A lot... Ive owned 2. Both were junk...
@@Andrew_460 If you say so. I can count in one hand the number of times we had to replace transmissions in Toyotas at our dealership over the four years I worked there. Most were the result of something else that was ignored or maintenance with bad fluids.
Thanks for posting, always enjoy your vids. You are one of the good ones.
Great video thanks Eric!
Everything that you do is beneficial for us as it is the "Real World" diagnosis and even if you are off on the first try it is so nice to see you as you go through these. Thanks so much Eric for all your videos and for taking the extra time for us to show life in the sometimes not so fast lane.
Eric, this is one of the best videos you have ever done.
Very informative post about how different problems can cause the same issue. What would have been great to see is how your diagnostic results changed after each repair showing how each affects the overall effect of the problem.
Thanks again.
Thanks for sharing you experience and know how with these codes Eric. Much appreciated bud. 👍👍👍👍👍
Great fuel trim problem diagnosis....with the essential big picture view and sensible checks for the basics! Eric you give such good advice.
Thanks for this video I needed this one
Top tier video as always!
I like when you show how to diagnose and repair vehicles I love when you when do the whole process and thank you for the information and videos
Enjoying your video.
Thanks
Thanks for this video Mr O Because i have 2011 Tahoe with 5.3 liter .
Great video. Not using an OEM part can have you chasing your tail on MAF, TPS , oxygen sensors, and idle speed control units. There is so much crap out there on Amazon and EBay. Thanks for an enlightening video. Too tier gas is of ultimate concern also. Pine Hollow had a great video on a Mercedes that had all these codes, and one tank of top tier premium solved it!
4:15 well Eric-O, with my OCD I would have washed that intake box and applied some kind of plastic conditioner to it 😂. I do like a clean engine bay!
Why just the other day I removed my washer fluid jug and cleaned it out - refilled and just went about my day. 😊
Well done Eric,a gut video,brilliant.
Thanks for the video Eric.
Great video. Thanks for the info.
Heck I enjoy a good outing at the junkyard.. I go there myself often I usually take a picnic basket.. last time I had to pull a head off of 2000 Civic
I watch all of your videos they are always informative entertaining and provide very factual information. Thank you for your efforts.
Great video Eric.
As always Eric, your knowledge and experience of legendary! Great video. (I like RockAuto never had a problem with parts fit or performance. I’m just a driveway mechanic)
I for one love to see the process.
Man, we missed out on a trip to Wilbert’s!
Sometimes experience is key....
This reminds my of the days when Chrysler K cars would do that rattle in the back because part of the rear axle would rot and break or the Ford Escorts when you lifted up on a rack would make that boing noise ( spring noise ) rear springs would have rot and have been broken and yea.
Thanks for the incredible diagnosis video's helps an old timmer thats not in the business anymore kinda keep up to date..
nice to know about top tear gas
That was interesting, Great video Mr.O
Eric, Please do more videos, your method of doing videos is excellent no droning on about removing screws or bolts but good explanation of what's important for DIY folks to know. I'm sure you get some really interesting repairs please consider recording those more in depth. The troubleshooting steps on this vehicle would have been appreciated. Thanks for reading.
Experience Matters ! 👍
18:37 Oh if i could only count the number of times I did something too early .... 😀
Excellent video Eric! Always good to understand your thought process and resolution of these issues.
Eric, Really GOOD info in this one. I only consider fuel when I suspect water in the tank, never considered where the fuel was bought, or even how a broken air filter housing could cause a $$ light to come on. Keep em coming!!!
Great videos, love your trouble shooting....ive been wrenching since 73 on everything and so many make too many thing too hard...you do a great job at keep it simple....I love junk yards too....best parts shopping ever...lol
I don't have the Autel due to cost but this gave me several things to look for and to load the cheap parts cannon options, like MAF cleaner or airbox.
I had a 2013 Tahoe and chased a similar issue. Had to take it to "my guy", who does great work. He was somewhat stumped, but then pulled the injectors, and found one of them was incorrect for that 5.3. Interestingly about a month later he told me another one came into his shop with the same issue. As always, nice job Eric!
