I must say Ray. As a parts sales manager at an auto parts store. I always recommend my employees to watch your videos and gain a little more knowledge on how automobiles work. That way we are not just telling our customers to buy random parts in hoping that fixes their problem. It gives me great satisfaction not having them come back stating “It DiDn’T fIx It!”
Well done. More people should do what you are doing. Unfortunately, as you would be well aware, the "parts cannon" will still be fired by many. Retired 70 yr old mechanic in Land Down Under who used to be in parts sales many, many years ago.
That’s a excellent idea!!! I remember when one could go to the parts store and the people working really knew what they were talking about when it came to cars and parts. Nowadays people get hired and have zero clue about anything with cars. Unfortunately nowadays less and less people are educated on mechanical issues so stores have no choice but to hire clueless people.
What a champ! A proper way to do business.
People in Florida seem very cheap with there cars.and they seem not bothered by coming to a shop for same problems.
Ray you have inspired this novice to investigate problems before packing the car off to the garage. By following your methodical process I have just diagnosed a faulty MAF on my mercedes diesel and had the confidence to take it out and clean it I also found a hose off the turbo.Keep up the good work mate
That’s pretty awesome!
Welcome to the rabbits hole, there's no escape now, you'll be very frustrated but on the plus side you'll have more money to go out and do things to relieve that frustration 😁✌️
I always bang it with a hammer when I don't know what to do
@@erickotapish7842 ahh yes the persuader method, if the persuader doesn't work then usually I resort to fire 😂
@@erickotapish7842 I see you've experienced a sticky starter in the past.:)
As strange as this may sound, this video is one of your most impressive to me. You really dig in and diagnose something and find the problem without a computer telling you what to do. I feel like a lot of mechanic work these days is more like part swapping. You are one amazing mechanic and you really showcase that in this video. Very cool Ray!
Most shops and I've had it happen to me they put me out the door my car didn't make it not even half a mile and it died because mechanics wouldn't take the time to get in the car and drive it around and diagnose the problem properly driving it around like you did was a good idea because you were not please till you found the problem you take it as a personal challenge I do too with mechanical things you did nothing wrong by driving around a few times have a good day
Ray’s ability to find issues using great analytical procedures is very impressive. I think some mechanics would have not gone to this extent and fired a parts cannon.
True Professional vs. Self Taught Amateur Professional.
@@nissan300ztt I know plenty of "self taught amateur professionals" who know better than that to just throw parts at a car. Those are known as ripoff mechanics; rip off one part for another, then charge the customer for their incompetence.
@@gotdangedcommiesitellyahwa6298 i get that. But more often than not people jusy throw parts at the car
Most shop owners be like: "we bought a parts cannon for a reason, please use it and make me more money."
@@garrettj416 Yup :/
Hey Ray, these cars are known to have the CVVT solenoid get dirty and cleaning out sometimes does solve the issue for a while. But what they are really known to do is have the crank position sensor go bad by intermittently losing signal for a split second like it seems this one may possibly be doing. It usually happens as they get closer to 100k which is the case in this vehicle.
If it does come back and you do get to see this comment, those are the two to watch out for. Also 100k is timing belt time if it hasn't already been done due to age. I have one of these, also a 2010 and will be swapping out the crank sensor as it gets closer to 100k, only at 71k at the moment. I visit family in Florida and don't want to have issues on an 18 hour trip to get there.
Hey Ray,
I really appreciate the diagnosis journey, anybody can do the tool/part replacement. But hearing, seeing the results of your thought process really helps me do my own diagnosis journey. So no worries about how many times you open or close a hood.
I was about to post a comment but this echoes my feelings precisely, keep 'em coming Ray
Ditto! I thought I was the only person opening and closing hoods, opening doors closing doors, ignition on and off, etc. Its a good feeling to know l'm never alone in the world of the "mechanical matrix ".
I agree. Diagnosis will always be the most challenging part, and it takes a mix of wisdom and experience that is not easy to emulate.
I thoroughly enjoy these videos.
To share a quote attributed to Thomas Edison, “I have not failed 10,000 times,“ he said, “I’ve successfully found 10,000 ways that will not work.”
As a retired dentist, I found this 'episode' especially satisfying. As Aaron John said, anyone can be taught to replace parts, but to put thought and reasoning into diagnosing the actual problem, that's the real art of doing your job well. Not everyone can do this. Keep up the great work you do for your customers!
The skill in any trade is being able to diagnose. Pretty well anyone can replace a part, with minimal training, but the skill is diagnosing. And sometimes, like Ray found today, they can be a real pain. Nobody likes guessing, even educated guessing, but sometimes that's all you have. Well done to Ray. At least many people watching this can see that the scantool is not the "be all and end all". It is a guide, a good guide, but you still need to use "what is between your ears" and unfortunately many don't choose to use that. Retired mechanic in Land Down Under.
There are shops out there that would have done nothing else but keep throwing parts at it and maybe they would have found it the problem they say a blind hog finds an acorn now and again wow you found a gem have a great day
It's refreshing listening to someone with a similar vernacular to mine from the well spoken to the very witty and goofy!
Plus I'm learning a thing or two the more I watch.
Kudos, Ray!
I have to say, this was one of the most remarkably interesting videos I've seen on your channel. Watching you puzzle out a doozy with one small symptom and almost nothing else to go by, seeing your mind work, and watching how you analyze and troubleshoot like that was honestly really, really cool. I'm sure in the moment it was massively frustrating to no end -- but seeing you work it like the ginormous flowchart in the back of those manuals one used to be able to get at eg Advance Auto Parts, except all right there in your head, that was amazing. You are both experienced and smart, and it shows.
Dude is a real mechanic. Love hear the thought process. I find this type of video very entertaining as well as informative. Smart dude
It wasn't the solenoid. You unlocked the secret repair code by opening and closing the hood 5 times combined with driving less than 10 miles all with a 1 hour period. PROCEED TO NEXT LEVEL!
Then shift into reverse three times without moving, honk the horn once, turn on the left directional and the CD player, and the smuggling compartment opens?
Ray, learned alot about diagnostic thinking from this video! Thanks !
Then begin the repair by removing rear bumper and inverting by the light of the new moon.
This was probably one of your best videos, finding an intermittent fault. Been there in another profession, so I understand how the mind starts running through possibilities.
Most can learn how to fix/replace parts, or whatever. But it takes time to learn how to think about a problem in order to fix the problem.
What a great bit of detective work, it just goes to show that the problems are not always told to the mechanic via computer and good old mechanic work is needed. 👍
I think that goes with his years of experience. You can have all the book smarts in the world but this is a situation where his gut and experiences has helped!🙂
Good old detective work is a must. Sometimes there’s no other way. Yes the longer you perform these types of things the more wisdom you have of where and what the problem is.
Hey Ray, Whaddaya say? I'm pretty sure my family thinks I'm crazy for watching you working on cars, but the virtual experience is priceless. Thanks for sharing your expertise and process with us. Also your sense of humor and philosophy of things.
Hey Ray, I enjoy your diagnostic videos most of all. Please, never feel like these aren't useful to post.
I think Ray should do a monthly "Special" video where he does a super clip of all the brake clean he sprays. I'll bet he can get 10 minutes per month of just spraying brake clean.
Add "Nice n' Shiny!" Audio, and we've got a Hit!
That was Mass Air Flow cleaner.

Incorrect Correction.
ANOTHER!!
I'd wager 10 minutes a week!
Not every video needs to be a mechanical fix. This one was interesting because you used a series of deduction methods which finally led you to the problem. Nice one!
Always nice to open up my phone to a new video from Ray.
Every morning.
This was not boring at all, the thought process you went through was logical and accurate. Great job
Yeah, I didn't see this as a non-repair. I saw this as a non-replace at the end of a GREAT diagnostic journey.
Diagnosis is one of the most time consuming part of repairs, all the best to you and your loved ones
Intermittent faults can be the most difficult to troubleshoot. I thought the scan tool could be set up to "record" and when you test drive it it "should" record the fault, like when the CEL flickers on the test drive. But I get what you are saying about the PCM not finding "mechanical faults" (like the armature of the solenoid was intermittently sticking) but only "electrical" (like if the coil in the solenoid was intermittently open or shorted to ground.)
I had a customer that had a Triumph TR-7 (Saab slant-4 engine) that had a really loud "screeching" sound under the hood on some mornings. It NEVER did it for me even after test driving it every morning for a week. Other than that temporary noise the car drove fine and everything worked properly. He was a very regular customer. Then finally one day I heard it. Turned out the three screws that held the pulley on to the hub of the air-injection pump (remember those?) were ever so slightly loose. I couldn't feel the looseness by hand. It was only when I checked them with a wrench that I knew they were loose. Obviously some mechanic long before me didn't say "click!" loud enough when tightening those bolts :-D Less than a minute later, torqued to factory spec of 20 ft-lbs with loud, audible "clicks!" (loud enough so the bolts could hear it and know they were torqued to spec).... problem solved.
Great video Ray. Love the diagnostic content.
ETA: It was four years from when the TR-7 owner first reported the noise to when I heard it and fixed it.
Most scanners will capture data stream , but only when a tru code is set. They also capture if you push a button. Both functions useless here as prob is mechanical
@@peted5217 sort of. The engine computer captures the data stream when a fault triggers the check engine light. It's possible that it captured some for the momentary instances. This history data can be accessed with the diag computer. I think this is what you are referring to as automatically recording it. Some diagnostic scanners allow you to record the data though. That requires a press of something to start and stop recording.
But even though this seems to be a mechanical fault, it should still be detectable via the diagnostic tool. The computer will command the variable valve solenoid on and display an expected value of the cam timing. Reading the actual value compared to the expected value can point you to the actuator not working. From there, it's the same or similar to what Ray did.
But... you have to know to look for it. That is to say there is a lot of data that can be so overwhelming that it wouldn't jump out as obvious unless you were clued into that system in the first place. But luckily, there are only a few PIDS compared to the entire set that control the engine actually running. This means if he didn't stumble onto the vvt connection, it is possible hr coukd have discovered it with a lot of mind numbing staring at recorded data playing back.
@@sumduma55 @ that point it would have been less expensive to just set it on fire. Properly billed for all Ray's diagnostic moves at current rates , this should have been several $$$$hundreds.
How often have you had to spend hrs gleaming thur data stream in search of a .001 sec glitch. I was a bigger fan of Ye Ol Tree fallbak
'Replace with known good part'
For Moi, it worked 90%+ of these nitemares . In this particular case , history of vvt actuators would have been a good clue to start with. No doubt you'd have done similar checks for likely suspects.
@@peted5217 you don't really have to really spend hours looking through a data stream. A recording has a time base and you have ideas of how long into it the fault appears. Especially if you stop recording shortly after the fault.
Ray kind of stumbled onto the root of this problem actually trying to validate a theory that the engine computer was bad. Swapping a computer in to test would likely be way more expensive than diagnostic time looking through data.
That being said, my point was more to that even though this was ultimately a mechanical issue with the vvt solenoid, it actually could have been detected using some of the advanced functions of the scan tool. Not that it should have been used or anything. Just that it's an option.
But I guess the question now is, if all you want to do is check codes and swap parts to see if it is fixed, do you really need anything much more than a code reader?
Oh, and he said he had about 45 minutes into diagnosing it. How much is the going rate that 45 min comes to hundreds of dollars? Last I checked, the high end of general shop time was about 125-to 150 an hour with most places being closer to 85 or 90 an hour and of course a 1 hour minimum. We'll, in my area anyways. I do remember sone shops in the 90s would charge a diagnostic fee of around 80 dollars just to hook a scan tool up. But I thought that was a thing of the past.
@@sumduma55 what's the Value of Ray's diagnostic time . 90% of 2daz techs will spend hours on intermittents getting to the same conclusion. In many ways the problem solving is similar those in medicine. The more experienced &/or more clever gets it sooner, therefore has a more Value (albit with higher fees)
Thanks for add'l scanner info. I had no idea how useful they could b til I bought one in 1990, jus a few days ago.
Love your videos. It never ceases to amaze me how many people come in and ask to have a problem diagnosed only to choose to do nothing. Now it might make sense if the repair was more than the car was worth but if they are dead broke and could afford nothing for repairs OR had zero interest in spending money on the car, then why did they bring it is to begin with? I am wondering if they just want to know what parts or adjustments are needed (because they have no clue) so they can go home, watch a RUclips video and try to fix it themselves. I hope y’all charge a reasonable price for diagnostics.
I did in fact find this helpful. Finding the problem without the fancy schmancy scanner is both commendable and laudable. Good job.
Rainman Ray is really amazing at his job. There's just no two ways about it. Fred
Not to forget: Scanner invaluable in kwikly eliminating other possibles .....
The entertainment for me was seeing you problem solve a frustrating problem like that. Your experience and knowledge shine.
I love these kind of videos where you diagnose a fault. Any one can do brakes and exhaust.😁
Not boring at all Ray. I love complex diagnostics in which I actually have to use my brain to figure problems out.
I really liked this piece, Ray. It's very interesting to observe your diagnostic method and thinking.
Sometimes the trouble is not clearly present so you have to infer what it is by what it is not doing. You provided us a classic example of this type of trouble. Nice Job and have a great day.
to me i seemed like it was just losing ignition for a split second: as if in an older car, the coil just hiccupped and didnt fire a spark for any random plug. Also, plug wires faulting to ground was a good thing to check too. but the vvt thing: I woulda *never* thought to look at that, and you went right to it. You have amazing instincts and im in awe of your abilities.
You beat me to the ignition cutting out possibility and I also 100% agree that I would never have even considered this problem being related to the variable valve timing. Great comment, at least in my opinion! Thanks to Mr. Ray the automotive Rainman! Fred
I agree to. You are a good and honest tech.
This fault would most likely left an error code... that is why he started to search fore something that can be faulty and not leave a code...
His are Jedi instincts.
Hyundai coils constantly fail
THANKS FOR ALL THE GREAT WORK I GO BACK AND WATCH THEM LIKE OLD WESTERNS
Learn a lot watching your videos Ray keep up the good work. And have a GREAT day.
In my opinion, this was a major win! We got to see some A+ diagnostics WITH explanation and not just.. "wow, it might have fixed it... weird". Plus, your first disabled thing diagnosed both the ECM's ability to store a code AND gave us info about the potential problem. That's really cool. Dunno if disabling that VVT solenoid was a lucky guess or if you planned that.. either way, highly enjoyable and informative. This video was not a loss!
Young Ray you must use the force
Tip for the DIYers like myself if you can graph the timing even on a cheap ODB reader, when the car hiccups you will see negative timing pointing you in the right direction (in my case the vvti gear not the phaser had failed by sticking occasionally and never throwing a check engine light) hope this helps
not everyone owns a scope
@@blahblah8182 But you can get cheapish OBD II bluetooth or wifi adapters, and use an app on your smartphone, some of which can read live data, like Torque Pro for example. It's more accessible for many people than you might think.
i have a snap on scanner and many obd devices to connect to my phone the obd on the phone will not do live data i have torque pro its only a code reader and that is not a scope
The idea of plotting sensor output helped me. Have a Blue Driver ODB reader. Car would buck at highway speed. Graphed MAP output. MAP reading went off-scale during a buck. Replaced MAP and no problem.
Ray your troubleshooting is very much like my own when fixing computer hw/sw issues. Your process is fantastic!
The popping the hood and driving around is actually quite useful, this video gives great insight into your troubleshooting process when the ECM doesn't give you anything useful. I never would have thought "let's unplug stuff and see if the problem goes away"
I found that very interesting too. Also, how he was trying to determine if the ECM was working. Great video Ray!
On behalf of us aircraft mechanics, thanks Ray. We don't get the luxery of test drives. We have to listen carefully to what the actual discrepancy is, and address that issue only until we come to a discrepant part. We only have some test equipment, our system knowledge, and experience. All this is put to test daily as is your own. I believe you would make a great aircraft mechanic. Hat's off to you.
The thing is with aircraft I respect you guys because you make sure it's right because if something happens you can't park an airplane on a cloud have a good day
Starting my day off with a cup of Ray ☀️
Coffee+ Ray every morning. It’s routine now.
As an old wrencher from the 60s I impressed by your diagnostic abilities. Unfortunately a lot of techs would throw parts at it hoping for luck. Great work.
If you suspect the VVT solenoid, you can go into "engine data" and watch the cam timing. Throw the D8 into graphing mode and watch for a drop or spike.
Is there a sensor on the cam timing? So the ECM can set 'advanced cam' and see that it happens? Ray said the problem was unseen to the ECM and yet the engine check light came on...perhaps its geared to cut the injectors if the valve timing is detectably out? But if so pulling the VVT solenoid out of circuit should have caused a fault. Nope. I still see no rational explanation that fits the facts here yet. I bet this one comes back again.
@@leosmith848 I'm pretty sure every engine with variable cam timing has a cam position sensor. So while the computer can't monitor the exact position of the solenoid plunger, it does monitor the relative position of the cam and crank, which should match up with expected values based on what the PCM is commanding the solenoid to do. And if the cam/crank relative timing doesn't match up with what the PCM expects (i.e. if the cam is over-advanced or over-retarded compared to what the PCM is commanding), it should throw a P0011, 12, 14, 15, and/or P1349. Since none of these codes were present, I'm also thinking the solenoid wasn't causing the issue, and problem likely still remains.
As for what it might be... I have no idea. All I can figure is it is an intermittent electronic fault. The whole situation where the MIL comes on only during the moment the engine cuts out is very bizarre... It reminds me of that GMC Canyon on the Pine Hollow Auto Diagnostics channel, which he worked on with Keith DeFazio. The engine and dash would completely cut out under very specific driving conditions, and there were no helpful fault codes stored in the computer. Took them a ton of work with the scope to verify all related sensors and wiring are good, at which point they could confidently condemn the PCM, which did turn out to be the culprit.
Yes there's a cam position sensor. The fault won't set a code if it doesn't persist for the minimum amount of time.
@@aaronbritt2025 Ah, then I think that your scenario exactly matches the evidence. The cam position sensor is occasionally not sensing the position at all. Perhps removing the solenoid and splashing brake clean fluid on it has somehow cleaned the sensor.
@@dphoenix1 Thanks for that really in depth description. How any motor repair technician is supposed to know all this is beyond me. No wonder the parts cannon is cheaper than the Phd repair man.
I am not so sure Ray wasn't real close, but no cigar. If the cam timing sensor was marginal so sometimes it missed a beat altogether - or the crank position sensor for that matter - then depending on the software the ECM might simply decline to issue a whole revolutions worth of injection and spark commands. But not issue a 'cam out of range'
I can see that one revolution would not necessarily set a code either. I think I would have wanted the cam and crank sensors put on a scope and compared with a known good working installation.
What I don't understand is, if that were the case - and it fits the initial symptoms - it all went away when the solenoid was disconnected. Unless somehow the sensor is only marginal when the timing on the VVT is advanced. Which is possible. Or maybe Ray just revved it more than the customer ever does and that fixed something.
(My car complains about 'turbo two valve not closed' if I give it a heavy foot. Normally I don't. that takes it from 250bhp to nearly 300..and who can afford the fuel burn? - but it has happened twice and since then I've been able to max the engine out without it happening again. )
Ray, your diagnostic process and your approach to working out the causes are why I watch your videos. This was a journey, thanks for taking us along for the ride! 👍
I enjoy watching Ray work his magic while having my morning coffee! Thanks for the video Ray!
Coffee and Ray everyday have a good day
@3:43, the engine light when on momentarily! Did you see it? Since a DTC was not set, I suspect the camshaft / or crankshaft position sensor. I had an engine once that would not set a code for missing CPS pulses due to a magnetically 'shorted' sensor. Cleaning the metal bits off the end of the sensor cleaned up the signal and it never needed attention again. Probably because I was a more frequent oil-changer - so probably fewer bits of metal circulating to bridge the magnetic-gap.
That is the first explanation that seems to fit the facts as to why the engine check light was coming on and yet no codes were stored, and it also explains why the ECM might decide to simply not inject or fire cos it don't know where the crankshaft is. I.e. it was waiting for the position sensor to tell it where it was, and never got an answer!
Way to check that is a scope on the sensor...
I saw that and wondered what the heck happened
Thank you for showing the whole process of diagnosis, you did a great job
Ray I enjoy watching your videos and they teach me about das auto. I especially like the videos that you are unable to rely on the diagnostic computer and then have diagnose what the problem is. Not because I want you to have to work harder, but that you show me how to do that type of diagnosing since I don't have a computer.
Thank you Ray!
If "good to go" is the criteria for working on your own car, it is certainly OK for someone on a budget to accept for their car. Good option given. Good service given.
Good man Ray.
It's nice to see that there's great people out there that you can trust working on your cars. Wish I had some one like you Ray that I could have to work on my Durango. Always a pleasure watching and listening to your commentary while working. Great channel you have going!
Morning Ray! Coffees almost done.
It is the new start-stop while moving gas saving feature.
Time is never a waste, even if nothing is found. Being thorough is always the best solution, thank you Ray! I can't blame them for not replacing it right now either with these tough times we're all going through, but on a happy note they now know if that happens again, they know the past in need of change.
Two caveats: You’ve wasted your time if:
1) you didn’t learn anything, or
2) you’re playing Solitaire on the ECM computer.
🤣😂😆
I also was impressed at the diagnostic solutions. Been chasing mechanical gremlins for decades. I know how much fun it can be. Also, you aren't the only ones to have SCAT busses. Years ago I lived in WA state. Skagit County had SKAT busses.
Congratulations, you went back to an era when mechanics (even American mechanics) repaired vehicles and were not just readers of electronic devices and fitters of overpriced parts. You actually repaired and returned a component to a vehicle, a skill not shown much at all, even on RUclips.
He does this every day lol, he’s done it like this for 20 years
Its fascinating for me, as you say " I guess it isn´t a total loss" This video still had bound me to the chair just watching it interested . So plenty of Content right here, good job
'morning Ray....Cheers from Calgary,Canada! (I'm a fan)
If I were the owner, I'd have done the same thing. Drive it as is and let it develop again if it's going to. In the 'olden days' we didn't replace plugs or points just because they were dirty, we cleaned them. No reason why it shouldn't be the same for a modern day solenoid. Having now watched the video and seen how simple it is to replace, if the fault did re-occur, then do it myself. Great video Ray, keep up the good work.
Had much the same fault on a peugeot and after a lot of searching also found the valve was at issue. I was quite obvious when removing as it was gunky, the original one did have a gauze but the OEM replacement came without. Interesting and who cares how many times the bonnet is lited and closed shows the thought process that went into it. Good job. And I prob would have done same, not replaced the part until it became undriveable or much more noticeable.
What's a pooch-o ?
The diagnostic process is very interesting/entertaining to watch. It helps to see how you move through these issues.
Many moons ago I had a Bronco that started dying on my on the highway during a long trip.
I would get about half to a quarter mile between stall-outs.
I was able to make it to an exit and caught a mechanic who was just about to punch out (it was a Friday evening).
He listened to my tale, started the vehicle and heard it die, and replaced the in-line fuel filter.
-
He only charged me for the filter and five minutes, but I tipped him $40 for saving me a 140-mile tow back home and sticking around that quarter hour past his normal quitting time to help me out.
-
The old in-line filter would not even pass compressed air when he took it off, so I was running on what wicked through the filter and the dirt it had trapped within.
This video. This video should be required watching for all car owners! I have worked on my own cars, ( some times to my own detriment) and everyone should know of the limits of the computers and humans working on their cars. Pre computers I have fought electrical demons. Often for a long time. Worst one ended up being rust underneath the bracket that Ford decided to run the ground from the battery. Rust, underneath the bracket for something else that used a bracket bolt as the bolt for the ground from the battery. Two years.
Would proper oil change intervals keep the varnish from building up on sensors? But yeah, good call finding the problem. Your videos are worth watching. No matter how long they are.
Using pure synthetic oil like mobile 1 produces less varnish.
It seems like this engine was fairly clean in this case. but you can also see why it is so important to keep it clean inside. Can you imagine the condition of this solenoid if the engine barely got any oil changes? They are recommended at 3,750 mile intervals for a reason. But I think even with the best of maintenance, this would eventually be an issue and at least need to be cleaned.
I wish all mechanics were honest and professional as Ray it's a very much privilege to watch!!!
Before I watch in full I'm guessing for ECM. Saw this on Pine Hollow, just dies then comes back. I'm probably wrong, I'm no mechanic. And...... following watching the whole video...... I'm wrong, that's why I'm a retired Nurse and not a mechanic lol. Great video Ray.
I mean you were sorta close...
Well, considering you had the same hunch as Ray had, I would call it a win :)
Love the way you are so thorough there Ray!
This example shows you how much more time it took to diagnose problems before computer monitoring. Tripping a code cuts diagnosis time to almost zero.
Funny how people think though that you can just "plug in your computer thingy and it will *tell* you what's wrong"
Codes don't necessarily cut diagnosis time to almost zero. Plenty of people have fired the parts cannon as a result of a trouble code, and not actually fixed their problem. If you look at the factory diagnostic manuals for any vehicle, they DON'T say "if a trouble code indicates component X, replace component X" - you have to follow a diagnostic process, which might well indicate that the component is fine and the actual problem is somewhere else.
You're not a mechanic, and neither is Scotty Kilmer.
@@ls_812 my code reader helps me save 75% of my time. I started working on cars in 1975 too.
Cars(engines) with no computers do not have a zillion sensors and zillion complicated control units on it. Making diagnosis not necessarily easier or more difficult. Strange issue's like in this vid, are lot more difficult to diagnose than a bad running vintage engine. Especially mechanics trained to "Modern car, there is only something wrong when the computer tells you what is wrong".
Its good to see a vehicle technician solving a problem by using his knowledge and experience. To many rely on computers to tell them whats wrong with the vehicle then being unable to diagnose the problem.
How about running a ECM Live data record with the scanner while driving and review it for the time it cut out?
Pine Hollow would have had four channels running but Ray just thinks it out. As long as both come to the same conclusion then it's a win, win. But teah, Ivan and his scopes are epic.

I wish more mechanics where like you ray. Your passion for fixing cars right is wonderful!
When doing a scan of live data is there any type of reference chart that lists what the normal readings should be?
Depends on the manufacturer. Typically Hyundai's do
Yes, any in-depth service book will.
You were wrong as we do enjoy seeing you drive around making comments. Not to mention your great ability to analyze what is going on with a vehicle. Too bad that you don't live and work close by as I know my vehicles would be in tip top shape cause you would be the one working on them. Keep up the great content for us.
It was my understanding that 100K maintenance for a Hyundai was The Crusher.
In the shop this morning with my own "Jeep" and watching your vids while it gets repaired (u joint).
Kid brings in his car and drops it off with a set of new tires he wants installed. One problem, tires are too big and will rub! 😂🤣🤪😊
Thanks for the great content!
$80.00 for a solenoid? No wonder people think it's the mechanics that are ripping them off, little do they know it's the parts guys.
$80.00 sounds a lot, but you have to take into consideration the cost for the choir that sings during its manufacturing process, the cost of the velvet gloves they use to package it, the golden box they place it in for storage and the forty virgins that pray daily for its safe and successful installation and operation. All these things cost money.
Very good diagnosis. Thanks for thr journey through the process. Knowing and understanding the sequence of operation in detail is what made this possible.
Dude love your videos, as a tech I see a lot of stuff from dealers as well as customers and dude it does get crazy some days but you have helped out in some of your videos so thanks and hope you have a great day too
I must say, I really like watching your diagnostic process playing out. I reckon so many people would see no trouble code and assume no trouble or even worse, if the ecm doesn't know then how could I know? thanks for sharing your internal monologue throughout the process. It's a lesson to us all.
Great video! I like Ray’s thought process. That SCAT bus comment was hilarious!
i love the thought process and understanding the logic behind it. Awesome content as usual.
Ray, as usual, you FIXED the problem and didn't just fire the parts cannon at it. Come on, it's really nice up here in Canada, I'm sure your kids would love the snow.
Very very impressive, most mechanics would have customers paying for parts they wouldnt even need,even small problems you go above and beyond to get things operating correctly,I wish I lived in your area I would definitely bring my vehicles to you for repairs, great video, cant wait for the next one ,god bless and stay safe
I am entertained and/or educated every time I watch your channel. Thanks!
exactly Ray it wasn't a total loss it was an experience and you pretty much track down the problem great job bro😄👍👍
OUTSTANDING video. This was even more fun than watching you easily find the issue. Challenge. Makes good entertainment.
Thanks Ray I thoroughly enjoy your diagnosis bits I usualy glued to the screen, everthing else can wait, click.
A colleague of mine told me she was jet-washing her car one day and when she went to drive away the power steering wasn't working. I immediately thought about water ingress but she went on to say that she had to buy a new power steering motor for £1800. People need to watch your videos. And Ivan's!
Your ability to weed in or out causes/possible causes of issues in the car is what IMO makes you a top notch tech. Anyone can fire a parts cannon at it and still not fix the issue. The VVT cleaning was a plus to see...as to the plug wires near the edge of the engine lift brkt, I would have filed it a bit round so that cant become an issue ever. As for the busses...LOL...here in Seattle we have the South Lake Union Trolley...and yes it got lots of wtf's when it first came out...it makes me wonder if they were trying to get it more noticed.
A great video as always Ray!!
I am fairly competent at changing parts and firing the parts cannon. I have all of the right tools. But, it takes real experience, knowledge, and skill to know which part(s) that need to be changed. This video added much to my limited knowledge about which part to change even though you changed no parts at all.
This what I need. The way to troubleshoot a problem on a modern car. TYVM
@Rainman Ray's Repairs my mother's 2012 pathfinder does similar things. Just randomly shuts off/stalls but with no warning signs and no trouble codes. Sometimes starts right back up and other times wont start back up unless left to sit for hours. No stuttering or anything, can run like a champ and boom instant stall.
Did enjoy your logic of diagnosis to find the problem.
Ray, this is far from being a boring or waste of time one , but is in fact one of your best ones . Fascinated by the way you can make ignorant computer cars tell you what is wrong with them. My first reaction to anything with a computer in it is to run.
This shows the importens of knowing how stuff you work operate
I had something similar on a fast jet. Passive warning system just wouldn't work properly after a major service. I did the same as you, I know how the system should respond to me changing things like connectors about but what I got wasn't what I expected.... root cause was 2 screened cables that had been repaired by an idiot. Centre cables shorted to the screen then to a respective earth.....
4 full days with multiple guys trying to figure it out.... best fault I have ever diagnosed. Good times
Watching you work reminds me so much of myself. You just don't quit, always thinking broad view rather than tunnel vision, thorough pro at what you do and fine, customer is always right but for me I would not be very happy handing back a vehicle with a problem that may cause chaos later on.
You have a good one Ray and family, hugs from the UK
VERY GOOD DISGNOSIS! I'm impressed!
Ray I really would like more of this type of video. I learn more from the diag. process. Keep up the good work.
You know Ray, what you are doing is called “Stream of Consciousness“, and this is what makes your videos so good. It’s whatever comes into your head and given voice. “Cows!” So we have a running commentary of why you are doing what you are doing at any given moment. And if that means we get the “ DuuuDEeDuuDaDuuh” occasionally, it’s well worth it.
I am a current Oregonian, and I agree MOST heartily, you're spot on. It's good that at least a few people can articulate things as you just did, it gives me hope when most kids these days can't seem to spell their own name right on a test.
I live in Crawford County Ohio. I used to drive a public transportation bus for about 3 years. The transportation company was called SCAT. Seneca Crawford Area Transportation.
I was surprised that you didn’t check the battery terminals first. You have instilled that in my mind as a go to step one
I'm loving the diagnostic thought process. This is my kind of video. (I do IT PC repair... this is what we do all the F*** time.)
To paraphrase narrative @18:30...'We're hopelessly lost, but we're making good time.' I am satisfied and impressed with youir logic and method.
Another great video. Wow your level of patience. I was getting frustrated. LOL. So, no your not rambling, your thinking outloud. Really it helps us follow your train of thought. On harder stuff, like this. How many times has a frustrating thing like this just not get solved? I can't find anything 😩. Next mechanic. But wait, RAINMAN TO THE RESCUE!
I am totally impressed with this guy's diagnostic abilities
