Nissan Sentra: No Throttle
Вставка
- Опубліковано 1 сер 2021
- In this video we have a look at a Nissan Sentra with the big 1.8 that was sent to us from another shop with a complaint of no throttle (car won't rev up.) They already replaced the throttle body, gas pedal and come to find out the IPDM (fuse box.) Also the engine light was on with a P2100 and a P2101. However, none of that worked and they have collected their money from the customer and now it is our turn to fix it right. -Enjoy!

Respect the fact that you never throw anyone under the bus, this vehicle came from another shop is all you say.
Well.... at the end of the day they pay my bills haha. I NEED THEM! Besides when you do this long enough you really don't care where the car comes from. I see a lot of mechanics get hung up on that. I see it like this. Car broken , I fix it, I get paid..... NEXT! What they do with it after they pick it up from me is their deal.
We just know that any shop within X-miles (where X is a value between 0 and 120) of South Main Auto is the mysterious "other shop".
@@SouthMainAuto Well said.
If a surgeon cut out the wrong organ I would hope you'd be naming names. You wouldn't say "well he got transferred from another hospital". Defending the absolutely abysmal and straight up scam artist stuff that he often portrays getting in from other shops is silly. The bus is there for a reason, sometimes people do need to be under it.
I sure wish Missouri was next door to New York I would love to become a customer
Eric O. is the ONLY auto mechanic that can say "You can trust me folks" and I actually believe it!
There are others.
@@podamis314 if there were others he knew he could trust, I'm sure he would have said so.
Motor City Mechanic is another good one if you are mostly in to Mopars.
Ivan from Pine Hollow also.
Well he is the doctor.
I couldn't see anything else after seeing that crusty battery, my eyes were drawn to it all the time.
It's so common that the breakage yard throws the battery hold down straight into the bin.
Yes J T, that battery needs some good old fashioned maintenance.
that thing was nasty
My same conclusion, battery acid
@@MoparDan I would say it needs replacement. Looks like someone tightened the hold down too much and cracked the case just enough to let acid vapor leak or possibly even liquid acid. My guess is it needs new terminals and a fresh battery.
The "enhance" "unenhance" bit always gets a good chuckle from me
Everytime the brakleen comes out i jump a little. Everytime!
It gets me every time! For some reason my wife is always saying "enhance" to me. I'm not sure what she means by that.
That and he brake clean sound effect!
When I first subbed this channel, I thought it was another voice doing it. Not that I think Mr O's voice is crusty, but it sounded different...and still does. hmm
"Just print the damn thing!"
Just scanned for comments about the battery. Was not disappointed!
You think we'd be use to it by now!
Wes, have you run over any downspouts lately? Mrs. Wes reminded us to ask.. haha
You guys are funny!
You're welcome....
The acid crust bridge under the hold down was a masterpiece!!! 😂
Again you have shown that diagnostics is not all about plugging computers in and/or following the manufacturers instruction! Another SMA common sense approach to diagnostics. Thank you Eric.
Yep one channel I saw the guy said he dosnt work on anything older then a 1996 and I knew it was because it would be OBD 1 lol it’s like no one can work or figure anything out without a computer telling them what too do
@@ryans413 Oddly, the older cars are easier to diagnose if you use logic. Fewer computers and systems to trouble shoot, just follow the wires, see if you have spark and fuel and your good to go.
I'll step out on a limb and say Eric takes common sense a step further and applies scientific method. Yup, he all scientific about it which means he insists on knowing defintively.
Hey man you are the BEST. I had my daughter’s car sent to the Nissan Dealership and they wanted to charge me $3000 in labor and $1600 for the Harness. Me watching this saved me Thousands. Thank you so much for your service and knowledge of vehicles.
Glad I could help
Once again the ingenuity of automotive engineers gets left on the table with crappy wiring designs. Who knew that placing the most sensitive of electronic components under the hood of the vehicle would ever be an issue?
Very through breakdown of the system and your diagnostic skills. Well done Eric, well done.
The issue is actually one that conquers many an Upstate NY vehicle. Salt-ass roads. Wiring gets hit. Mechanical parts get hit. Rust and electrical corrosion happen. Mr. O is skilled enough to understand that this happens and where it's likely to happen on vehicles he services and how to deal with these as he fixes said vehicles.
Using super-thin wire, no slack to absorb shock, hooda thunk it?
@@LadyAnuB Andrew Camarata often bitches about this very thing, and points out that if vehicles used marine grade wire these problems would be null. I'm not sure how accurate that statement is, but it seems to make sense on the surface.
@@markh.6687 - Don't forget, placing a connector down low at very front of vehicle, subjecting it to water spray.
@@LadyAnuB
Yes, salt does increase the galvanic rate of wire corrosion, but we’ve also got lead free solider and the lack of sealed components.
On my trailers, the first thing done on brand new units was to remove the bulbs and silicone grease the sockets then reinstall the bulb.
The entire rust belt of the US has the same issues as seen on NY state vehicles. Fluid Film is your friend.
Thank God, SMA is back!
I am fortunate to have a guy in a local shop that thinks like Eric. Just in the last two weeks or so, about 5-6 cars have been towed in from another local shop that the other shop could not repair. As far as I know, they've all been repaired by the second shop. Kudos to Richie and Richard. Two VERY experienced mechanics! Great guys.
Eric o has done a thousand times what other shop and dealer mechanics couldn't do. He is the guy who needs to go back to school to get a teaching degree and get into teaching auto shop classes at college! Could you imagine him as an instructor. He'd probably be the most well liked and well known auto shop professor in the country, is all! The man has knowledge and charisma which can't be beat! And he loves....Ice cream! Lol. I wonder since Mrs o got her new kitchen renovation, that maybe an ice cream machine isn't out of the question now! We will wait and see. Later. Jpol.
Really like the way you broke down the diagram and demonstrated the electrical diagnosing process in this one a little more in depth then usual. Electrical is not my strong suit and that was a nice little demonstration. Please do more this way 🙌🙌
Troubleshooting an electrical problem in a car can be a nightmare. They do all kinds of funny things with the wiring and grounds etc
I couldn’t resist - radar detects a hot Mrs. O! 👍
It's just Mrs O's laser tracking
Lets hope its not the vacks serum 😲
E is like a Jedi Ninja Mechanic... Some of the best diagnostic skills I’ve ever seen.
I love this channel!!
Without a doubt! My automotive electrical shop class teacher was missing in action when I was attending a certificate course, show watching Mr. O logically troubleshoot the electrical part of a automotive system is extremely informative / helpful. He shows you the importance of knowing how to use a wiring diagram & when to question what doesn't seem right - that TSB that recommends replacing the whole IDPM module!
It's a great channel for sure.
Fantastic Eric ! I don't understand how the other shop let that crusty battery get by. It is as if they threw their hands up in 5 minutes, and said "Out of Here !"
Not all people who work on anything have Mr. O's natural mindset or honed skills from experience. It's the way he is wired. Good for him, his family, his customers and competitors. We should all be so fortunate to find our natural talents. The fact that he can share that with so many people is awesome.
No parts canon required! Ivan would be proud of you! Thanks, Eric.
No Russian hacks required well kinda jumped a connector lol
Also no cannon! That's fairly canonical for Eric.
Pachelbel approved!
@@ryans413 I probably would have done that -- or worse.:) My comment was not a dig on Ivan, btw. He's definitely smarter than the average bear.
@@kastooMcFry your cool man no worries
"Bob's your uncle." This is the second time I've heard Eric use this quintessentially, and almost archaic, British term. The full term is "Bob's your uncle and Fanny's your aunt," which goes back to the 19th century. The Fanny portion was probably dropped in the early/mid 20th century when fanny became a British slang term for the female pudenda. This is why in Britain the typical tourist fanny pack is called a bum bag.
He seems to be a fan of AvE (very cool channel); AvE uses that phrase a lot. I think he’s adding a little Easter Egg for fans of both channels.
Well would that be the same as Robert is your mother’s brother?
@@brianunangst4447 I kept waiting for the focus you fack during the enhance.
@@yqwgjsg That must be the posh version
@@cgmoog im always saying it in my head expecting to hear Eric say it too xD
Hmm, I generally assumed no acceleration was intrinsic to it being a Sentra.
Intrinsic to the CVT transmission killing itself out of nowhere on these garbage piles.
Funny, i was looking at a 15 pathfinder for $1500 the other day with the same problem. Seller already replaced throttlebody and gas pedal. Guess its a nissan thing...
Kudos to you for repairing in a way that considers the technician that might be working on it next time. This is the way that you do all of your repairs, and ; the next tech to work on a particular vehicle just might be you. Thanks for the video.
"Sounds like a bunch of lil woodpeckers out there" Had me rolling.
it’s so good to have a quality mechanical fixit man to watch once again . i learned so much . thankyou
Um, ain't nothin' mechanical about this fix!
Agreed. This is my latest binge-all channel!
@@John-vi5vb i particularly like these diagnostic shows . the way to find the problem using to scan tool computer and schematics . pinpointing the control wires from the computer through the relays and spaghetti combination connectors . very very interesting . beats the old ways of unplugging all the connections and checking every pin
I'm impressed that you have such a gut insight to circuit analysis. Your experience with test lights and relative control currents is amazing. I would have tried to use voltage measurements in most places, but those can be misleading since relay circuitry is largely "current" mode. Also, voltage tests can be deceptive since circuit faults can reveal as variations in resistance rather than fully open or short circuit. THANKS for the lesson!
As a electrician I love it when it is too difficult for someone else, I like a good challenge
So do I
I label my aftermarket circuits, helps me later!
@@okymek Jobs where somebody has already been in there: extra time to unravel what they may have done.
Sherlock holmes gets his man :-D
That midway connector is just trouble waiting to happen.
All of the other wires there may be growing green crusties. Eric did right by leaving that alone (just cause more troubles) and installing the bypass.
Wish there was more mechanic's like you I love these kind of videos tracing wires is a skill its awesome thank you
your worth every cent you charge... only wished you lived closer so we could have you work on any cars here.. great job.......
Eric O is absolutely amazing! What most mechanics find as hard he finds easy.
Having the correct service data and correct wiring diagrams are critical for the techs. Also your knowledge and experience of electrical are impressive. I am retired now but love to watch your videos and others to learn about this new technology in our autos that is changing every day.
Welcome back Eric. You've been missed!
Amazes me... Every video, ONLY 10% of the viewers like it... But as usually, 110% entertaining.
The longer you do this the better you get the longer i watch you the better i get Thanks Eric
"Trust me when I say, trust no one" - let that sink in a second....lol
Radar detector in a car that does 0 to 60 in a weekend that made my morning
Thanks Eric
In a world full of part swapping shotgun monkeys with hammers, you are by far the cutting edge of auto repairing evolution.
I love the commentary; "Lady you have problems now. Your magic box is no good!" I would pay money to see her expression.
The man is an automotive genius.
Welcome back Master Eric!!! "Normal" has returned!!!! :D
I am 64.. retired was an auto Mechanic for 35 years I have chased down all kinds of electrical problems ...You did a Great Job !!! ...DON'T let that vehicle go without cleaning up the battery acid and cable ...that is the cause of the green corrosion !!!
One hello of technition. This a guy you listen to first ask questions second. Damn fine job. Glad your back. Young techs pay attention and really listen.
Cant wait to see the upgrades to the shop!
SMA video goes great with morning coffee. Thanks Eric!
Working at the Chevrolet dealer. A 2017 impala LTZ had a battery leaking battery acid. It ate through the main harness. The technician had to tear the interior completely down and replace the whole harness.
South Main Auto is the best ever . i am learning from you a lot
Thank you for showing us how you approached this, step by step, right down to the single-conductor level. Your videos always show me how to gather data and logically think through problems. They've also taught me not to be afraid of complexity, because complexity can always be broken down to simple subsets that are easy to understand.
My meema taught me many moons ago to divide a circuit to quickly diagnose a fault , as I was a flat rate tech at the time naturally I told no one ....
Nice job 👍
Can you elaborate on what you mean by that?
@@firstlast--- 🤣🤣🤣🤣🤣
Always great to see an SMA vid in my notices. Great diagnosis as always. Can't wait to see the changes to shop. Thanks, Eric!!
LOL! That wasn't a radar detector it was a hotness detector! Way to go Mrs. O!
Poster boy for deductive reasoning!! Great video,thanks Mr.O
nice to see you back on the green crusty's eric, eliminating green crusty's is a job for you.
Can’t wait to see the changes to the shop.
Eric a true honest competent mechanic. The world needs more.the battery with all that nasty crust is spreading its cancer! Wash that crap onto the connector and bodabing bodaboom.
A true master in the field of mechanic work that was a joy to watch thank you
ICBM used to mean “intercontinental ballistic missile”
38 minutes from Russia with love………BOOM!
It still means that plus China these days. North Korea, Iran are close behind.
Can't wait to see the new and improved SMA!
Amazing diagnosis! I always learn so much watching you work.
Always impressed with your knowledge, patience, and methodology. Excellent work.
Top quality work Mr O - again!
Finally.
My SMA fix.
Thanks Eric!
SMA always coming through with the proper fixes!
Welcome back sma
Glad to see you back
What about the front ?
Love when you explain everything just like i remember from kindergarten
you are an old-school mechanic in a modern world. don't work? find the actual problem and only fix that. simple. you are awesome :)
Awesome! If only all mechanics were this good!!
Yeah! Proper diag vid! Good to have you back!
Very happy to be able to watch your videos again..
The best way to start my day, with SMA !!! Great detective work Dr. O !! 👍👍
one of the fist things I learned in my auto shop class, way back when the moon was blue, was a wiggle test. just wiggle wires until something starts working. that method has helped me prove many plug and pray mechanics wrong that the computer knows everything. computers will only tell you the circuit, not the problem.
100% correct! It still has it's place in modern automotive diagnostics. As long as there are wires in a car it is a place to start, just be careful where & how hard you wiggle those wires so as not to create another problem. It was a method I used at Amtrak to locate a bad power cable on the train's motor. The indicator light on the dash would flicker when you wiggled the offending cable.
It also comes at a cost if you manage to wiggle something and make an intermittent problem go away only to come back later after you ship it back to the customer.
@@Discretesignals Correct. I guess it all depends on exactly what you are working on. I would think that some fixes have been found even accidentally by moving something to get a better look & suddenly the test light flickers, etc. Mr. O is a master at tracing faults & he is confident and generous enough to share his knowledge.
Enhance...enhance... I've missed hearing that! Can't wait for the "new" shop tour!
I have been a viewer/fan of your channel and Ivan's. There is a clear difference between you guys and other technicians who work at dealerships. The care and workmanship you guys do is far superior. You guys treat customers cars as if it was your own or a family members. All the best to you and yours.
Your the best in the biz Eric, I've learned so much from watching your diagnostic vids, glad your back!
Logical, intelligent fault diagnosis, good work. Love that wire tap tool, wish I had one myself.
20:31 - Enhance, enhance... Dare I say a 1982 Blade Runner reference in a vehicle diagnostic video. Touche sir, well done!
Eric o is a silly man it’s probably a reference to a reference from super troopers lol
Possibly super trooper reference
Haha! Too funny. The Super Trooper bit is making fun OF the Blade Runner bit. Blade Runner came before. The detective Dekard pours a whiskey, sits and uses a voice activated machine to scan a photo at zoomed levels. "Enhance! 131,25 Pan Right, Stop" In the 80s it was futuristic. Funny that we have voice control now. Bests Eric, bests all~
The owner installed junk, as an eg. tapping directly into the positive battery cable but at the same time leaving the engine bay a veritable mess would make most shop mech's just throw all sorts of major electronic parts at it. The thinking would naturally be "this car has been fudged with in so many ways - it's just got to have fried part of the ECM or some such. Love how you are essentially making every one of your vids a perfect "teaching tool" for even the experienced.
So glad you are back posting.
Dang Eric O! You're gone for awhile remodeling the shop, and then you show back up and knock one out of the park with this sweet video. Things must be looking up! Hope things are going well and keep going well. Good job man. 😀
The “BIG 1.8” ! A beast for sure ! Lol thanks Eric for another knowledge bomb …
Great vid Eric. Thanks for showing us the logical process and the final outcome. Thanks for sharing.
Eric, that's a good fix for that cheap hooptie that doesn't have many years ahead. You're a Master at Diagnostic Troubleshooting.
Good job Eric! Troubleshooting accuracy beats shotgunning parts every time. Thanks for another great video.
Welcome back! Was missing the videos! Hope the remodel went smooth!
So good I watched it twice. You are the man. Thank you for taking the time to teach, I watch every video. Especially the electrical diagnosis.
I really appreciate your diagnostic skills
Brother you have been missed .An thanks for another nice heads up .🇺🇸🇺🇸🇺🇸🇺🇸🐺
Perfect monday morning surprise .
Great to see you guys back kinda like loosing a good friend there for a while
Excellent job Eric O. You make those jobs look so easy. I wish I had that talent.
Never will I understand the lack of troubleshooting. The second code literally says missing PWR at throttle body. A one minute check at the throttle body would of confirmed that and then go backwards in the circuit and you would of found what Eric did. Also, can someone please change that air filter, gross!!
Would've does NOT translate to "would of".
@@JW...-oj5iw it also doesn't translate to "please grade my UA-cam comment for grammar." Mind your business, you're not their teacher and this isn't school.
Some people just dont get it. They cant read wiring diagrams and understand a troubleshooting process.
@@OneTrueCat ... 1. Find a rope. 2. Pissss up it.
@@OneTrueCat If we let this kind of crap become main stream, do you know what sort of language we'll have 100 years from now?
Great job Eric. It's great to see the logic process a true professional takes to diagnose a problem.
Nothing like watching an auto repair garage with hammering in the next bay....🤔 LOL...I was waiting for.. "I NEED A BIGGER HAMMER."
As always, well done Mr. O.... I admire your diagnostic abilities 👍
I have learned so much by watching this channel. I'm not a mechanic, don't plan on being one, and I barely do more than the basic maintenance to my cars these days, but I love learning. I love that you teach more than automotive on your channel. Respect, class, calm under stress, process of elimination, and just how to enjoy life.
Snap on knife owner is panicking. They still owe money on it
3 easy payments of your soul to carry our logo around on overpriced tools.
It's their punishment for throwing 2 parts at a car without diagnosing anything

your back . fantastic
Excellent diagnostic work and repair Eric.
Eric your diagnostic skills are awesome!!!!
Pretty amazing how young folks love to add all kinds of aftermarket stuff to their cars yet fail to follow simple maintenance procedures like cleaning the battery corrosion off. Talking to you my grandson!
Not to worry, the battery only provides weight to balance the front of the car! :)
Some of us exist, minus the random electronic crap. I even detail under the hood! My acura bay is clear as hell.
With all of the diagnostic data that you have shown us, I was able to help out a local woman with a throttle sensor issue and steer her to the right mechanic with the proper scan tool.
Great vid Eric! I’ve been kicking ass with the mobile diagnostic work. Busy every day! I learn a lot from you, Ivan and the UA-cam diag. Pros. With education, service Data and y’alls videos there isn’t much I can’t figure out. Thanks for creating dang good content!
Always wanting a nap after lunch is because mrs. O is feeding you real good. Your a lucky man Eric.
