3 1/2 years from now you'll claim that you are just a normal mechanic, not some god. well, over the years your perseverance has served your customers well, AND you take valuable time to show the path you take, so thanks for all that eric!
Man, that was some impressive troubleshooting! That salt certainly is pervasive. I was thinking the car manufacturers may have some stock in the salt producing companies. If you want to get rid of the salt, just convince a couple people the salt is harming animals. It will be gone so fast, your head will spin, and no more green crusties!
If anyone can do it you can Eric! You really don't mess around, a true master at his craft.
Hey Brian thanks man! Unless it is a Ford then we all know were to send them too ;)
@@SouthMainAuto The junk yard is full of them.
you all prolly dont care but does someone know a way to log back into an Instagram account??
I was stupid forgot the account password. I love any assistance you can give me!
@Brayan Emmett Instablaster :)
@@SouthMainAuto Just a thought, Next time ya got to do a car like that I would grab the shop vac and try vacuuming all that dusty dirt out from under it to make for a faster clean up of the shop later. lol. Okay well now that I am seeing under the hood at all that dust, I am at a loss of words. lol. I hope He keeps his air filters changed. Like Always, Great Job Doing what you do tho!
"Your car is fixed and ready for collection."
"?."
"Sir, you can come collect your car, it's all done."
"How can it be? All the other shops had it for a week and then told me they couldn't find the problem. I dropped it of yesterday and now you say it is done.
Is this a wind up?"
Way to go Mr. O. At the beginning you said the owner wasn't the best communicator, now he has his trust in mechanics restored he may be a bit easier.
I worked on a 2015 Malibu today.
P0245, Fuel pressure signal issue. The park brake cable beat the harness, and damaged the 5v supply wire. Same area as your video. Repaired the damaged wire and good to go . Your video was helpful :-)
The old "we made it worse so we are on the right track" senario at 36:00. Brings back memories when I was young and did this stuff. Sign of a good Tech just works through the problem.
Eagle eye Eric. You could smell that broken wire, you're not fooling me. One of your best. A little long (broke it up in 3 ) but a real cliffhanger. Thanks Eric
Yeah there was a lot of fumbling in it so it ran long. Not my best work...
Excellent job spotting that broken wire. In the future on other jobs that have all that dirt blowing around you might want to wear your SAFETY GLASSES so you can continue to see that well. Take it from a retired tool maker safety glasses saved my eyes many times. Great video, looking forward to part 2.
Dennis Wilkinson needs a mask !
Another super video! I'm surprised that thing didn't come in with a new pressure sensor in it already. Most everyone would have just changed the sensor...connect scanner..."blah blah blah fuel pressure sensor blah blah blah". This is the reason why diagnostics is so intriguing to me.
Visual Inspections man!
This video is proof that Eric O. Is the Master Technician who can fix damn near everything!
How many cars are sitting in the junk yard due to one bad wire. Excellent work detective. Its a real life mystery as to what the problem is/was and that wire was not in an easy place to fix.
"Shop hoppin" + Challenging problem = Last Stop SMA. Nice fix Eric. Thanks for sharing!
I'm about 240 miles away but I'm bringing my car to you. Great job running that broken wire down. when the other shops gave up.
Hey Eric O, I think you should do a tool tour of you're tool boxes. Anyone else agree?
I can't believe how bad a condition that car was in !! I would have been totally embarrassed to have any of my cars look like that -- I don't even think that the undercarriage wash would remove 50 lbs. of dirt !! I can't believe you found that wire short -- you, sir, are nothing short of AMAZING !!!
Eric the Car Guy has Cameraman Brian... And you've got Camerawoman Mrs. O!!! Well done!
Hey man, I just started watching your videos and I have to say, I am impressed with your work ethic and the work that you do. Also, it's awesome how you and your wife work together. You guys look happy.
Yes sir we are. Been married ten years yesterday :)
Congratulations!
@@SouthMainAuto 10 years - CONGRATULATIONS !!!! A match blessed by Heaven !!!!
Shop hoping... should have just started with you. I really enjoy watching you diagnostic procedures. You have become one of my favorite shows to watch including TV. Thanks for the great videos.
Had a few of those folks who dont understand what and why things need to be done as they are . It's tough on the guy trying to fix the car when the owner give them a rough time and had plenty that had to be towed elsewhere.
Wow, Eric, you found that broken wire fast. This is just another example of your excellent work and impressive skills to be able to convey the important details that are necessary for us to understand how it is done. Thank you.
I live in France and it's very hard getting information, what with mechanics either now knowing or not wanting to share info. I've learnt an awful lot watching you work and good news is, i've just discovered your channel. Which means many more of your videos to watch. Thank you very much Eric.
eric...I've never seen you so unsure with an issue like this. Glad you finally got to the broken wire.
You earned some serious bonus points with "One mistake I didn't make was marrying you Though".
"As applies of gold in silver carvings is a word spoken at the right time" - Proverbs
on camera too! what a guy! he truly loves her! Eric o you are the man!
Mrs O's face really glowed when he said that! Good on'ya mate. Keep your woman happy :)
The kid is quick on his feet
Lmfao bro 🤣 @Bruce L.
I love your attention to detail and your sparkling personality lol I like how you explain things in a manner that people who are not mechanically inclined can understand I myself as an auto mechanic know a lot of the stuff but I can honestly say I have learned a lot by watching your channel please keep up the good work
Great video! I just discovered the channel. Its nice to see actual diagnostic work which is getting rare these days. I go to a shop that still repairs and doesn't just throw parts at everything.
YES !!!!! Finally a video that is more than 5 minutes to fix the problem !!!! And this one is a MULTI problem fix !!! Went thru a big cup of Krups machine of McDonalds coffee insert, and it tasted great with some chocolate wafers to compliment it !!! Our (yes, our - you are not the only one diagnosing the problem) sleuthing is going along nicely and uncovering bad things that have happened over time !!!! I saw Mrs.O.'s heart lovingly melt when you said the only mistake you never made was marring her - priceless !!!! A bad wire so far, gonna fix that. Then on to the other codes and more sleuthing again. Can't wait for part two !!! Going to fill the Krups water tank because it will take at least two cups of coffee and a few Dunkin Donuts of white cream, blueberry, and jelly fillings to get this vehicle all repaired and an inspection sticker slapped on !!!!!!!!!! 🤪🤨😵💫😤👍
You are so lucky! My doctors won't let me eat any of the "goodies" 😞 🖖🏻🍀
Eric I will have to say from a mechanic of 35 yrs I tip my hat to you sir. Much high respect of all the electronic experience you show. Also love all the respect and love you show to Mrs O. Keep up the great videos cause I will have to say I have learned a lot from you on electronic diagnosis. Sometimes it can be a nightmare. Have yourself a great day from Kansas. 🇺🇸 love your channel!!
I am not one to say things on these auto repair videos, but I what thank you for your narrative video. The way you this video, you allow the auto DIY mechanic to watch to understand what you were doing. The cables use over and over again can fail. I work on electronics and keep a well supply of the test cables. I learned long ago never believe it the equipment interior circuit board showing a bad resistor, I now check it with a fresh cable that doesn't have broken interior wires. A+
Great vid as always but the best part is @ 51:00 when Eric O puts on the master class in Dr O Luv Doctor and pays Mrs O a compliment that genuinely get her giddy and makes her smile bigger than a country mile. Great couple.
What exactly was the car doing that other shops said it was irreparable besides showing a code? Great video love all the info you give in the troubleshooting process!
awesome vid Eric at least someone is dedicated enough to go threw that crap to find a problem like that..others dont seem to go that extra mile.. but others arent making you tube vids to help the little guy out either.. so thanks for that ...kudos
Great diagnostics Eric. I held my breath there when it looked like the Autel was lying. (as I just ordered mine)
And that scene @ 50:57 with Vanessa blushing was priceless !
never know a scan tool has lied to me before!
Eric, at 25:00 I have my guess made: I think it is a high resistance (of some ohmic value) when everything is hooked up, between the senor and the PCM, the majority of the 5 volts is dropped across this high R. I'll wait and see what happens.
Eric spent quite a bit of time diagnosing those 2 problems. I would be curious how he would bill that out especially if the customer chose NOT to get the repairs done at his shop.
In MI, the shop has to give you a WRITTEN estimate before they start to work on the car. Some dealers are now charging a 1 hour diagnostic fee before they look at anything ! The fee is typically refunded (baked in) if the repair is done there.
I enjoy watching these videos. The beautiful Mrs. O, ( very respectfully ), and an ace mechanic. Excellent skills, and still running a shop while making TH-cam videos. Excellent electronics experience, and diagnostics. Keep it up. Watching you all the way from Alabama port, Alabama.
This video is one reason why I always come back to the SMA channel. Eric is the car whisperer fo shore. Can’t wait to see what the outcome is after the repair. Am gonna watch that next
Eric, nice job on that wire. We in the HVAC & R and Commercial Cooking repair trade go through a lot of the same, tracing down missing neutral wires, in your case grounds, chaffed wires shunted to ground giving erroneous readings and the like. Some of the ovens we work on cost as much as a BMW 3 & 4 series, so the customers get a bit mouthy if we don't find the problems on the initial visit/diagnosis. I like the way you never give up, when others would. I look forward to the rest of this/these video(s) on this job. So many times a single shunt or open wire can cause a multitude of faults. Good job!
You are really good at finding those hard to find problems!
"This is a piss poor design" about the cable being routed right by the strut. I can tell you as an automotive designer, our job is to fit 10 pounds of manure in a 5 pound bag. I learned that on my first day on the job.
Look at the ten pounds of dung. Can you Increase the moisture content of manure to add weight without much volume? Then shovel ten pounds in the bag. You’re only seeing what your taught to look for. Guaranteed it won’t leave SMA with same issue.
It’s a piss poor design.
For the “designer” it made it past warranty ✅
@@ohell226 It's an expression. We have to work around what's already there like sheet metal, suspension components and the chassis. Routing of fuel and electrical lines is always last. What my comment meant was that we're left with an almost impossible job
A good visual inspection wins on this one. Great job Eric !!!!! You lit Mrs. O's eyes on fire with that line at 50:55. Great Job !!!!!
hey I gotta lay it on when I can
Hi there Eric, I'm new to your videos and am impressed. I have a 03 Chev Malibu that I do like to keep running at 100%. I have a mechanic next to my American Legion that does all my work that I don't do . I just replace fuses and minor stuff. Like I say, let the Professionals do what they do best. Every Man needs a job... I look forward to your future repair video's.
Looks like the owner went full Dukes with all that dirt..lol Great job finding that bad wire under all that dirt. Geez Louise! Dirt`s still falling! Major points with Mrs. O, her face really lit up when you said "One mistake I didn`t make was marrying you. You are a very lucky man with a lovely wife and family. Keep up the great work. Thanks for posting your videos Professor O.
Great job Eric O , not one in a thousand would ever find that problem, great camera work Mrs. O.
Oh sure, any one who tried could fix that car easy!
But not the shops the guy took the car to previously, it seems! Nice one Eric, love watching you work :)
This problem required all your skills Eric. Very interesting to follow
Mrs. O Tripod; Well done ;-)
Great diagnostics Eric. Guess the initial quality awards for the GM products don't extend into the second year.
Another excellent video. Great detective work. I particularly like your real world videos including any missteps which are part of finding any problem.
Eric, you hold some sort of statistics of your shop, I wonder how many GMs Vs order brands you serviced. Love how they manage to intal modules were salt, rust, or dirt tend to acummulate. Love this cars designed and tested in the desk of some nice office building. Rust can get into autocad I guess.
Dang the car had a sand gravel yard under it 😂, almost looked like concrete mix.
Wow what a mess that was huh looks like the owner didn't take care of it to well some preventive maintenance probably would have helped. Great video Eric and Mrs O
Every little issue you had was in itself a learning curve and despite all that you performed a very detailed process of solving this problem.
Was looking forward to you pulling apart the wiring harness. Great troubleshooting skills bro. You're the man.
Great Video Eric, your troubleshooting skill's are very logical & professional. Most repair shops are parts replacers. Keep up the great work.
Great diagnosing Eric....wonder how many cans of brake clean it would take to clean the under side of that beast?
I've inherited a GMC Sonoma with the 2.2 5 speed and it has 200,000 + and people have told me that I was going to have all kinds of engine problems but have had none so far and I drive from Mississippi to Texas all the time . I have had really good experiences with GM products thru out my driving days
John McKamy you fuck guys dont you
I know this is an older video, but this is exactly what I"m dealing with with my Malibu. Same year, same model. Thankfully I paid for an extended warranty.
thank you for the videos, it always amazes me how you find the problem when no one else can. thank you also for having Ms. O on the channel, it's cool the see her and fun to see the interaction between you too. take care!
U just need to slow down, i.d. the circuit and find the problem. Just try is all I do.
+South Main Auto Repair No, you find the issue with patients and thought. That's more than 90% of mechanics. Don't sell yourself short. You are among the few Good and honest mechanics. Still wish you were in Texas. Take care brother.
I didn't think that the words "maybe we can't fix it" could ever come out of the great sma channel!
Can't win them all sir
South Main Auto.. It's not a job, it's an ADVENTURE! Another blow me away video! Thanks!
Eric your an awesome guy. Hes like a chuck norris in machanics, he just looks at a car, and it fixes itself in fear lol. And Mrs O is so sweet. Keep up the quality work you folks.
Thanks Eric, I enjoyed that one. The power of a visual inspection still lives!
visual inspection is key! unless you are watching Schrodinger's box then u are an asshat if you do visual inspection haha
You Da Man!! Thanks for another excellent diagnostic video. Very timely also since I was starting to have SMA withdrawal attacks.
Good Job. I took an hour video plus behind the scene time to solve this pressure sensor issue. Finding a broken wire is not an easy job with all these wires and wire harnesses.
Thank you to share this job work, information and experience.
One more thing please, how did you fix that broken wire ????
That's why I wanted you to be so good. Not everyone can think like you. Step by step, I have accepted you as a teacher.
Love your patience as I would have thrown that updating scan tool across the shop....
Good job as always. I have a 16 Malibu with the same engine and submodel so if I come across the same codes I'll know where to look. Thanks for all the good content.
i realy enjoy seeing the prosses including the mistakes please make more parts im raely intrested to see the other problems.
im a plumber from CT who dose auto mechanics as a hobby and iv been watching your vids for about 2 year. thanks for sharing your knolage keep up the good work.
Thanks! Glad u enjoy them!
Is that Chevy's new mud undercaoting option? Also Mr. O and Ms. O make a great team don't they! Thanks for the great repair videos guys!
That looks like the car sat in running flood waters and that is dried mud. Even the engine compartment is coated with silt. I'll bet you will be seeing that one coming back quite frequently.
That parking brake cable on the right side looks rubbed through to the metal as well.
I guess the panels on the underside are to reduce wind turbulence.
Mrs. O. did an excellent job on the camera. Great Video!
Brilliant video,learning a lot from you,thanks Mr and Mrs O.
I’ve owned a ‘62 Chevy II, a ‘65 Olsmobile, a ‘67 Camero, a ‘68 Camero, a ‘72 Olsmobile, a ‘76 Firebird, an ‘85 Firebird, a ‘90 S10 Blazer, a ‘99 Tahoe, and an ‘04 Olsmobile Alero.....they were all rock solid, dependable vehicles. But after this video, the use of a GDI fuel system and the shoddy electrical harness routing that were built into that 2014 Chevy Malibu have put me off of GM products for good. That Eric O owns and drives a Toyota Tundra and a Honda Odyssey is all I need to know.
Lol many blue with white. Welcome to the life of a diesel mechanic. I do diag every day and just for instance Volvo wires are mostly all the same color!!
Especially in the dash
You should put all of that dirt in a box and give it back to the customer. After all, it is thier dirt LOL.
Michael Herbert Add an hour of labor for the clean up.
Nice Job man..I like the patient yo have in searching ..and being sure of what you 're looking for..and the techniques yo use in jump-wire the broken leads........blessings man!
Great job and lucky it was something that was visible to you, awesome work ethics.
your amazing the patience you have with a dirt dropping car
nice vid Eric O. Hope you are ready to see the old 2002 Chevy HD to do some work on her! No surprise to me the amount of crude under that cover! My 1987 Chevy PU with the outside frame mounted gas tanks had plastic covers. Within 8 years the covers collected enough crude to rot the gas tank out! I left the covers off when I reinstalled the tanks.
Oh man I see it in my books! Are you bringing a camera?
Probably! just wait until you see some of the stuff the other guy that worked on this truck did! wow! And will be fun to see if the parts that were ordered by owner are correct. you will be in for a loooong day!!!! HAHA!
Rip and tear is all I do when they come in... rip and tear!
Really hoping this isnt whats going on with my kid's Malibu. Great video. Thanks for sharing.
Are you sure that car wasn't under water for a period of time? I've never seen one that packed\clogged with dust and dirt especially at only 2 years old. It just seems way wrong even for a car from the northeast.
You’re a great mystery solver and a great mechanic if it was me I would’ve burn the car.
Awesome vid , the camera lady did just fine. Lots of great testing Eric. 👍👍
from one mechanic to another your diag is awesome not too many mechanics diag properly and just change parts keep up the great work A+A+A+
You're an excellent mechanic Eric, if others couldn't fix it that means if you can fix it doesnt mean others can. So much for your statement that its usually a connector problem but amazing that an emergency brake cable did that, yes POOR design. I just watched the cam solenoid video, I would like to see a cam with multiple lobes. I am surprised people go to other shops when you're the best
Incredible job of pursuing the problem. You tracked it down, great work.
thanks Eric that was a good lesson in a logical approach, thanks very much for this invaluable training cheers sandy
It is just so hard to understand: the fault code indicates a faulty sensor, and the under body cover hasn't even been removed by the previous shops. That really is incredible.
i should just thumbs up before even watching at this point..
Thank You Eric, I have two Daughters driving 2014 and a 2015 2.5 Malibu's. Next LOF and Rotate I will do a visual on these Rear Harnesses. I agree, you married up!
He says "honey, are you decent". The Mrs. is a good sport !!!!!!!
Well ya never know haha
I don't want a car like that, but I think cars like that are in all our futures.
nope. Electric cars are our future.
I just ran into this same problem on a 2014 Malibu but I had a P0449 code and no power to the vent solenoid. The red wire was rubbed through in the same exact spot as on this vehicle. I had to lower the fuel tank to test for power at the vent solenoid and found I had no power. I also wasnt getting a ground signal from the PCM when commanding it on with the scanner. Once I fixed the broken red wire all was good.
Love your shows please keep making new episodes I have a Nissan Xterra 2006 with 185000 miles and no problems since new love cars and I watch to see what problems they might have thanks
Maybe this is one of the flood cars - all the silt everywhere?
Bad sandstorms in New York ! Good piece of detective work Mr Holmes ! Jury is out on the usefulness of the digital test light ? Vantage pro is still a reliable piece of kit. Vanessa looks great.
The Vantage is the best all around meter u can get IMO.
Another Great Video! What a place to put a wiring harness! Seriously? Reliance on one sensor for all those codes? That fuel pump probably has been running at max output for a long while, shortening its life! Hey! Mo money for you when comes pump changing time, RIGHT? Cool! Not cool is the multi poundage of dirt and who knows what else! If you've ever seen the Space Shuttle land at Edwards Air Force Base in California on the dirt landing strip you know what that dirt is like as you removed some of it from that vehicle. Went to an air show there about 7 years ago, parked WAY OUT in the dirt. Leaving at night had the RECIRC door closed, but it took MONTHS to get rid of the fine dirt from under the Nissan truck! And it was a PAIN IN THE ASS to clean it from all parts of the vehicle! Like you said, that sensor should have been under the hood. Oh well. Part 2 with the P2XXX codes coming up! No sleep again tonight!
+
Great video Eric!!!!...Thank Mrs O. so much for holding the camera!!!!.... so we can see the broken wire!!!!.....Thanks Eric for this video!!!!....that code list looks terrible!!!....but you show us not be intimidated for that long list of codes!!!! many of them are caused for a rubbed and broken single wire!!!!......I hope you could make part2 video!!!!.....Good job!!!.....Chloe has been growing so much!!!!.... greetings to all at SMA!!!
This is less automotive repair and more archaeology.
LOOK! It is a Malibuasaurusrex!
@@SouthMainAuto LOL.
I use to live next door to a mechanic couple. He fixed vehicles for a Dodge dealership. She complained about why he would fix neighbors car's, while her brakes were chirping. They have 3 kids I've known since they were little. One is now a teacher, one is a very high paid stripper/dancer and one is in college studying bio chemistry and is also a great mechanic. The couple is divorced though still remain close. They are all my friends and now all live in another State. I guess what I'm really trying to say is...
I really miss those labor free auto repairs lol
Eric, the Astro digital LED test light is 0.2V under what it should be over it's entire range. I checked several with my Fluke and that's the number.
Yeah the light I was using was one Lisle tool sent. It is ok but I have to agree. I love Astro but the test light leaves room for improvement we will say...
It looks identical to the Astro. Likely them got them from the same source.
i'll send u pics it is actually totally different
Again, we appreciate your videos. I've learned alot from them. Thanks Eric, and everyone at your shop that is patient with you and your quest to teach the rest of us.

Yup good person mechanic
Listen buddy you the f****** best person and electrical problems a mechanic too but you f****** technician guy thank you seriously
