I suspect we don't because there's not enough money in it. It requires a huge amount of very detailed information, but I doubt the pay reflects that.

[@elcidcampeador9629]

@@normcook9335 That is not my suspicion. The average labor rate for mechanic work is $110/hr roughly. Obviously the cost of running the shop absorbs a good amount of that, but even if mechanics get half of that, that is a good wage these days. More likely the case is that we have lazy boys and young men who, instead of pursuing trades, sit in mom and dad's house until they are 30 and live on government hand outs and minimum wage jobs. The labor participation rate among young men is lower than perhaps ever in American history, and for every 5 men who retire from the trades in general, only 1 or 2 replace them. The trades pay very well these days. Apprentices usually start around 55k, and I know that established contractors are easily pulling down 150-200k a year if they have a good work ethic and organization. I see no reason why a good mechanic like AMD cannot achieve similar levels of success.

[@Weathernerd27]

@@elcidcampeador9629 I'm an electrician working under one of the big unions IBEW local 46 and you are right about about trade work, $47 to $70 per hour for a job that doesn't require a college degree is very good pay but there are a few major drawbacks to working in the trades. 1) Commute, I get sent to construction sites all over the county and my commute is often really long. The company makes 0 effort to place people at construction sites near home in fact if you are good they are more likely to send you to the further away to the problem sites. I've been living in a Van during the workweek and comming back to my condo on the weekend because I got tired of 1.5 to 2 hour commutes. 2) despite the high wage we don't get much vacation or sick pay so during COVID many of us came to work sick and one point more than half the crew was out with COVID. I can take 2-3 weeks off per year because I'm single and good about saving money but some of my co workers with big family bills can never afford to take a vacation. 3) The work is not steady you tend to be either doing alot of overtime or be sitting at home wondering if you can pay next months rent. When times are good you are working most of the time but during recessions there may be no work for several months. When you factor in the lack of vacation pay, lack of sick pay, downtime, the cost of a long commute and sometimes having to pay expensive city parking out of pocket its not as good a wage as it first seems. I'm not saying that trade work is bad it still pays better than alot of jobs but I think one needs to think about if they can handle the dirty/physical labor, bad commutes and stretches of heavy overtime before they get into the trades. I've given up on having a family because I don't think I'd have the energy to be a good father/husband after a overtime day and a long commute and I see too many of my co workers having to move back in with Mom and Dad when they get divorced because after paying alimony/child support they can't afford the cheapest apartment. Working for a shop doesn't pay quite as good but is probably steadier but it has to be the right shop because I've heard horror stories about shops that are super stressful and rush you to the point where you can't do a good job. I think the bad shop is more common than the good shop unfortunately.

She gave me a bunch of memory test and when I could not pass them I was told to just guess. She asked my wife to come in and asked her a lots of questions, never once did she ask my wife if she kept up with what I did day to day before the accident, if she had, my wife would have told her, that she had long ago stopped trying to know what I did day to day because it was not something she could understand when I talked about it. In the end she asked me to leave her office after I told her I could see she had not delt with my type of case before because of the info she just kept not wanting to take note of. I told her I needed a doctor with knowage of head injuries. I told her I was not calling her a bad doctor but like good gas and diesel mechanics gas and diesel both might not be their strong thing. She got real mad when I used a mechanic as a example and listed all her college degrees and time she spent there, never once did she say she had treated people with car head injuries that I can remember.

I love your channel. Most technicians use the parts cannon because they are paid flat rate to change parts, not to diagnose. The reason they had it for a week was it was a come back, they worked on the gravy jobs first. I apprenticed and went to school 2 years. The techs gave me the cars their parts cannon didn't fix because I worked for 5 bucks an hour and could take my time. The owner of the dealership had me work on a car his neighbor bought because one more time and it would be returned under lemon law, and he was embarrassed. He told me take as long as I need, but fix it right. It had fuel trim code, they had changed fuel regulator, fuel pump, etc. I connected scan tool and took it for a drive to see what fuel trim would do (newly hired, barely knew anything about EFI as I grew up with old cars with carburetors). As soon as I left the noisy shop, I could hear the vacuum booster hiss when braking and fuel trim changed under same conditions. I pulled back into the shop and asked parts man to order me a booster. He thought I was crazy, called the service manager, said it's a fuel problem on the order and I wanted brake parts. I explained to service manager how vacuum leak was throwing off fuel trim. He told parts man to order it. Service manager loved me after that, Car never came back. After becoming certified, I was put on flat rate. The techs with seniority got the easy jobs. I might get hard ones or none at all, book 20 hours in a 45 hour week. Get paid $14 when customer got charged $95 (20 years ago). I went back to my desk job. Around that time, my friend took his Volvo to dealer, bad catalytic converter, $1800. He brought it to me. I had no scanner so I changed his downstream O2 sensor, threw an upstream on too in case cat was bad from running rich, left cat alone, code never came back. Saved him $1600 even without a scan tool using my parts cannon! Another friend had hard starting after car sat over night, I pulled out the parts cannon and shot a $50 fuel regulator at it, cheaper than $130 diagnostic quote. Sometimes the parts cannon saves money, but I recently bought a sophisticated scanner with bidirectional capability. Now I'm relearning after being out of it for 20 years. Your channel is great!

[@mousetoad7040]

@Paul you are so correct! Sometimes they don't know any better, sometimes they want the scrap $$$ that oem ones bring. Factory Cats rarely go bad, unless something is causing the engine to run rich and they keep driving it that way. I just changed the cat on my 2003 Corolla with only 99,000 miles on it. No codes set but there was a hole rusted through the case! The whole car is rusted out from road salt, a shame. Runs great. Probably 80% of catalyst inefficiency codes I see are bad downstream O2 sensors. Not a bad idea for folk to get a 2nd opinion on costly repairs.

Another great video, BUT I am not 100% convinced that the computer was really faulty. There is still a chance that it could have only needed a simple reboot or re-install software. I once had a TCC PWM lockup problem on a 4L60E that ended up being due to faulty computer. I think this may be more common than people realize as most people seem to by default just simply eliminate PWM TCC lockup, not realizing that it could be computer related (also while not realizing that PWM lockup converters should not be used without PWM lockup due to different clutch material). Everyone, including transmission experts claimed the vehicle needed a new transmission. But I kept testing the transmission and TCC thoroughly and it all tested fine, including continuity. Finally I started throwing a few parts in my despair, still not success. Only when I switched ECM, the problem 'miraculously' disappeared and hasn't appeared since.

This is just in case you have an interment problem with a wire shorting or opening.

Well a month after the swap, they did a good job with getting everything in there but the vehicle ran rich and I diagnosed it myself down to only leaving bad fuel injectors. I get there and they just tell me change this, change that without even looking at fuel trims.. I show them fuel trims and the mechanic doesn't seem to even understand what they were. I argued for a bit but finally got them to get some different fuel injectors and it solved the issue right away. If I wasn't mechanically inclined, I would probably be screwed in the same situation.

What you said at 23:00 about what the computer is saying about a code is what I have been preaching for years. Read the book on why the criteria is required to SET the code.

Gut said no, rich bank 1&2 could not be BOTH o2, parts don’t fail in pairs hardly ever. Guess what, wasn’t it. Used aftermarket sensors and that caused another issue that wasn’t apparent. Ultimately it was a leaking fuel press regulator and then I found my non AC Delco sensors didn’t have the shell to sensor grounded as required by the shop manual for them to work. Wasted a lot of time. Thanks AMD!

[@C-M-E]

From the DIY perspective, trouble codes are exactly what AMD said towards the end. It's a place to start looking, not a prognosis to start replacing. What's helped me tremendously in pinpointing problems is going through the voltages the part or sensor is expecting to see. My last issue started with a crank position code, which long story short, ended up being perfectly fine. I fell into the trap of replacing it initially, only to yank it back out, cleaned and put a lil dielectric grease on the old one, and voila, perfect function again. That was after doing 8 plugs and coils, then having another issue pop up where the MAF wasn't seeing the right values and started misfiring at startup but cleared once it got up to temperature. Cleaning it unfortunately didn't fix the problem but a new one from Toyota did. Case in point, I wasn't getting an MAF code, but checking all the systems data values to figure out what was really the problem got my truck working again. Had I taken it to a shop, who knows what the final bill would have been, but an educated guess would be north of $2000. Where I really got mad was paying for an allegedly Denso product only to receive a generic POS that was more problems than it solved. I'm now Adamant that only Toyota parts are going on mission critical components! Even if aftermarket parts are cheaper, there's no guarantee they will produce the expected signal or have the correct value the ECU wants. At that point, having to deal with shipping delays and ripping the engine apart twice, it's just easier to go OEM and do the job right Once.

As engineer, I can tell you have a mindset of an engineer “looking for root cause” versus just replacing parts and that is the best way to resolve problems. When the motor on my window stopped goes up and down, I disassembled the window to got to the motor. I opened the motor up and fixed the bushing inside the motor as I refused buying an entire new assembly as dealers don’t sell just a motor.

[@riverpirate1022]

Your even teaching mechanics how to do their jobs. Your awesome! I always struggled with electrical diagnostics because I never took the time to fully formally learn about what each test is and means and how to do them. I know some things. But I was smart enough to know what I don't know and get someone else involved when needed.

[@juanalejandrosotto6217]

It's not "common sense". It's the analysis of a master mechanic that makes it look easy. It took decades of experience to diagnose a problem in 15 minutes

[@ro-landocalrissian4633]

It’s extremely hard to find a good mechanic! Most people don’t know what they’re doing & end up messing up your car even more! & if you take it to the dealer, they end up ripping you off!!!

[@vtecem]

I think in this instance with a budget which might be tight. It might be a good idea to start looking into salvage yards, find the same make/model/year of car and hopefully one without damage to the engine area. Someone could most likely find a computer for a fraction of the cost of a new one. At the very least, if the car is a write-off otherwise, there's not much to loose.

[@walter.bellini]

Agreed

[@slingbart705]

go to a Pick-a-Pull with an empty tool box...$2 entry fee, case closed

[@elmerfrejoles98]

One thing for sure man, you got the cleanest auto shop without a doubt. That should be a good indicator that the customer came to right place to get his/her car diagnostics. Keep it honest out there man in making a diff to the auto service industry.

[@d1bergman]

This is exactly the kind of video I like to see you doing. The most important thing i learned here today about toyota is that the engine operations are in the big connector and small has body functions. I also enjoyed the process you use for double checking. I would do the same thing. Thanks please do more like this specially with the Camry :)

[@deadduck8307]

You are absolutely dead on. Toyota of Mt. Pleasant TX said the P0420 diagnosis on my '08 Tacoma was 'a really bad catalytic convert, basically non-functioning' direct quote. They spent < 5 minutes diagnosing it. My objection was being asked to spend $3K on a new cat with such little time spent on the problem. I had them replace my spark plugs. Why fight against a parts cannon, I felt. I felt it best to use the diagnosis fee to get a part I actually needed. After the new plugs and a bottle of cataclean (and a good 75MPH, 2 hr interstate trip), the code/MIL light is gone and has been gone for well over 1000 miles. You gotta protect yourself from parts cannon folk -- conversely though, if I did every come across an honest mechanic, I am not sure if I'd ever trust the mechanic enough to let them do their job just because of all the bad experiences. Shame on Toyota of Mt. Pleasant. They contacted me after I reported them to Corperate, but only to argue. It's a cultural thing there, not just the techs. Toyota themselves wouldn't help stating that it's the dealerships responsibility to ensure a positive experience. But hey, in the end I got what I paid for, new plugs @ dealer prices and a free AutoZone style code readout disguised as a serious catalytic converter problem w/ all the high pressure sales tactics you could imagine. Would have been far worse if I hadn't protected myself w/ a pre-thought out plan in the event they f'ed me. Specifically my plan was: if they say it's the cat without reason, have them replace the plugs.

[@bubba4072]

Another excellent and informative video by the Car Care Nut. Thank you!👍

[@jerrysdashingagain]

I’m a delivery driver for a living ! I’ve learned over the years to not trust any of the mechanics in the auto repair shops in my community because I’ve been burned in the past! This led me to learn how to properly diagnose and maintain my own vehicles saving me a ton of money and headaches. Just to prove to some of my colleagues in the delivery business how much dishonesty corruption untrustworthiness and lack of knowledge of the mechanics in my area has brought my car to three repair shops. I already knew exactly what the issue was what needed to be done to correct it. My car was at each one no less than three days and when I finally got a call back they were asking permission to do work and replace parts that were completely unnecessary to the issue I brought it in for!

[@majidabdullah6594]

One of my favourite series on car care nut eagerly waiting for next electrical episode 😍

[@Flow8888]

One of the best things I admire about the car nut is his absolute zero ego level…I’ve learned so much from this 25 minute video and that’s invaluable because I can apply that to my own working within the motor vehicle repair industry, I myself can have that arrogance and attitude to say to any potential customer that I know what I’m doing so don’t cross my path with what you think about my diagnosis and repair professionalism..so kudos to the car nut he’s not only taught me to be a better mechanic/technician but also to be more humble and respectful towards the customer who’s paying for the repair and keeping me in Business, to sum it up if you have a vehicle that comes in take better time to concentrate on what the problem in hand might be, and not just doing a quick component change that might be unnecessary and be at greater cost to the customer and also give more headaches to the both of you because in the end and as seen the part/parts changed still cause the vehicle to display the engine trouble light and not to run correctly..

[@CN-qw1rf]

we need people like you in the industry with special skills in automotive repair and maintenance, hope you will continue to educate us more with your work. Thanks a mil... cheers!

[@steverichdrummr]

I love how AMD can diagnose a car with one hand in his pocket!! Amazing, love it.

[@lifeisfuneh]

I'm shocked you could concentrate on the work with all the leafs there :)

[@Reggaejames]

It would be so satisfying to get a shop vac and just suck them right up!

[@keneckert1077]

I am a retired electrical engineering tech and have been following you since. I have been a Toyota fan since 1976. My son is a mechanic and has a difficult time with electrical diagnostics. I texted him your video and after watching it several times it all fell into place for him. He is now a follower. I like the way you diagnose problems and not just replace parts and hope that fixes it. Thank you for sharing AMD.

[@53thumper]

i agree with your process of checking power on both legs of the sensor. However, when checking for shorts to ground you should have your meter on resistance to the negative battery post to check for a grounded wire. a grounded wire will not have any voltage on it.

[@bronx-gr]

that is why he had it connected to the POSITIVE battery post as well as negative. A grounded wire will show -12V there (red lead to test point, black to positive battery post), if he sees -12V, done, short to ground.

[@53thumper]

@@bronx-gr Thanks, I appreciate that perspective. Since the sensor is powered by the ECU if it was shorted to ground it would have caused a failure of the ECU and not necessarily blown a fuse. If it had been power fed from the fuse box then the fuse would or should have blown, but still checking that way would confirm a grounded leg of the cable harness to the sensor.

[@AxRDesign]

Great video I love how you work. I have a 2018 subaru wrx and my dealership do a terrible job on my car charge a lot for brake maintenance,etc. And they do nothing on my car after winter I have brake slide pins jam and cause me issue... Now I find a great mecanic just like you to work on my car. I don't trust my dealership anymore... Just a big scam wanting to make money for poor job...

[@riceburner4747]

That poor Camry. I have a soft spot for Camry's. I owned a used 86 & 97 Camry. With all those leaves in the cowl, I thought for SURE mice ate the wires. Now, can u pick up a used computer from a junk yard? I hope they read this, get some Mother's Aluminum polish to clean cataracts from headlights.😉 Good luck with your repair! 🖖👍🇺🇸

[@dans_Learning_Curve]

After polishing, do you coat the len with something?

[@jeancassel]

Agree, depending how long they want to keep the car, a junk yard part can be an option.

[@riceburner4747]

@@dans_Learning_Curve O believe it IS a polish. Jst when they dull down, repeat again, its a cheap fix.

[@Blakecryderman7244]

@Rice Burner me too, I own a 1986 blue 2 tone Camry liftback 5 speed manual. Manual everything except steering. Just bought it 3 weeks ago from the original family. The interior & exterior are in amazing condition, only 187,000 kilometres on the car, which is definitely super low for being almost 37 years old. The interior is an absolutely gorgeous blue. Currently replacing the CV axles & struts on it myself. Using quality parts. Even though I’m only 15 I’m wise and keeping it stock and original.

[@chrisgabin3783]

He is a dying breed of mechanics. Outstanding I wish I had mechanics in my area like him.

[@SoulAir]

Did the aftermarket parts kill the I/O on the computer?

[@jamram9924]

No. The hard code was stored in the memo of the ECU. After the soft codes were erased, the hard code remained.

[@jeancassel]

Jury is 50/50 on that one.

[@mph5896]

The original part could have killed the engine computer. But its gone, so no way of testing it.

[@rajinkanhai8294]

I love watching your videos I learn alot

[@theylied1776]

The reason why I learned how to repair my own cars was due to my mother being ripped off by a dishonest mechanic. She paid almost $2,500 in repairs and they never fixed it.

[@anthonydiaz3350]

That is the biggest problem in the industry right now not enough real diagnose being done I work for an aftermarket auto part company and I get so many returns because of all the part changers out there who called them selves technicians not enough time diagnosing all they want to do is hook up a $30 scan tool and think they know the problem. It’s good to see somebody like you actually helping a customer in the correct way thank you for bringing this video to us.

[@dans_Learning_Curve]

Yes, you proved the wires can carry voltage, how about current? Eric O and others use a high current draw bulb to prove there isn't an issue say like in a splice somewhere in the harness. My sister scraped a car because the transmission would down shift at highway speeds! Shop couldn't figure it out. Without looking at the car, but a wiring diagram, I believe the issue was in a factory wire splice down low on the core support. I believe the TCM was loosing either power or ground and the transmission would go into limp mode which was probably 2nd gear!

[@chetanjiva8874]

This is a logical process for fault tracing electrical problems just like when a fuse goes. We don't just replace it.. we need to first figure out what caused it to go. Your experience and diligence is the reason why customers come back to you.

[@paulg.5997]

Your videos should be used as training for dealership technicians.

[@youngb1ood]

Car care nut is definitely my favourite toyota mechanic on youtube. The only one up on you is SMA, which does a lot for diagnostics. But you make it well worth it to buy/consider a new toyota. Dont take this the wrong way. You are amazing Ahmed! May the Lord bless your soul, since we've been blessed by you.

[@camryv]

Great video. One question regarding the diagnosis. Shouldn't the wires be load tested in case they are slightly damaged where the meter would read no resistance but wouldn't be able to carry enough current under load?

[@vg3430]

Yes…in my opinion, you are correct. I have tested circuits before that passed continuity tests, but due to other physical damage (loose connections, corrosion, wires half chewed) they were unable to carry the required load (current). Granted, these OCV’s probably don’t require much current to activate…but a test worth doing before charging $800-900 for a new Toyota ECM. My opinion only.

[@joehofmann3564]

You remind me of my Dad. The was not a mere parts changer. He knew how to properly diagnose the root cause the trouble. He would apply the same logical thinking that you do. He was always in high demand.

[@purplehills56]

Most times you can't just blame the mechanic most times the customers are cheap and don't want to pay properly to get the work than right. But I hope the previous shop sees this video and should be ashamed of their work.

[@mikekay631]

Hello I am a Diesel Mechanic in the Heavy Transport industry in New Zealand. What you call the parts cannon,We call diagnosis by replacement. You are 100 percent correct if some one does not under stand how or why the machinery they are working on operates,and do not have even average diagnostic skills. You are going to cost customers a lot of money in a hurry. Be it cars or trucks. Keep it up good to Some one of your experience and skills pushing in the right direction,even if it is in a different country to mine. Mike Kay

[@peterpeter5666]

as i was maturing in the auto industry I had to take many courses on diagnostics and electronics to keep up with the tech of modern cars , I even took some courses multiple times just because sometimes in a class environment you miss a detail or two or if you dont use what you learned often enough you tend to forget details. Problem today is that tech is moving so fast not even dealerships can keep up. I have repaired many cars that were botched by dealers cuz of the way they work and time limit put on techs . Its only going to get worse. NO new generation ( snowflakes) want to get their hands dirty and actually do work.

[@potatopotato8360]

Being an actual good mechanic nowadays able to deal with modern car problems (not changing parts) requires engineer-like aptitude and intellect. But the problem is most such talented individuals would rather work in well paying high benefits STEM instead of toiling away on the most challenging issues for flat rate.

[@surferdude4487]

You make that diagnosis look easy. That's skill, experience and a fair bit of intellegence at work.

[@victorbarnett8207]

I am an old auto tech, formerly a Toyota Master Diagnostic Technician. I love your professional and logical diagnostic approach. One detail you left out was to test the resistance of the OCV. Like you said, it's rare to see a failed Toyota ECM. One thing that can cause that is a shorted component. It may be that the original OCV was shorted and caused the ECM failure. But it also may have had a bad OCV to begin with, and the new one is shorted, and it fried the ECM. Testing the resistance of the component can provide you with a clearer picture of the whole condition.
