Toyota Engineers STUMPED?! (CRAZY Tundra P0019 - Part 1)

A desperate Toyota Dealership Technician reached out for help with a problem child 2017 Toyota Tundra 5.7 V8.
Customer got the truck submerged in a DEEP puddle, and now the Check Engine Light is on, and engine power is reduced.
After Shop #1 FAILED at diagnostics and repairs, the Tundra was brought to a Toyota dealership.
Now it has been at the dealership for over a MONTH, and is STILL NOT FIXED!
It's setting a stubborn *P0019 - B2 EX - CKP Correlation code*.
According to the technician, all traditional avenues have been exhausted, including a massive PARTS CANNON and multiple consultations with the LEAD TOYOTA ENGINEERS!!
This technician has invested DAYS of work into the truck, replacing various timing components, including a full set of chains (18-hour job!!).
Now the truck is even MORE BROKEN, also setting a P0018 in addition to the P0019!! Oh boy...
Let's read the back story and see if we can diagnose this truck from the DESK by looking at some oscilloscope waveforms, and comparing to a KNOWN-GOOD Tundra:

[@Sandmansa]

I've been a mechanic for over 30 years now. I started out working on motorcycles for about 10 years and graduated to working on cars and light trucks ever since. I don't personally own a pico scope. But I have access to a snap-on triton d10 scanner that does have an integrated 2 channel scope. It's not the greatest but it gets the job done. It has helped me with a couple of my diagnostics. There have been countess times when I have turned to Google and KZbin for help. I'm not ashamed of that. But one search result brought me to one of Ivan's videos a few years ago. I enjoyed how Ivan speaks to his audience and walks us through his processes step by step, all the way through. I've been a fan ever since. Ivan, you have helped this old tech try to better himself. And have shown me a few things along the way. I can't thank you enough for that.

[@brianw8963]

I’m kinda in the same boat. Though I surely comprehend the need for the Pico 4 channel to do some of these deep diagnostics , and as I just hung up My hard hat and steel toes, maybe I’ll get into it someday. But for now, if I get to that point and can’t figure it out, I know where to send it! 😅😅

[@andrewsorenson2267]

Hey Ivan, I’m a Ford Field Service Engineer and I’m always learning and developing myself. Lots to learn always and I personally really try to focus on following the data to make a proper repair and help out. I enjoy watching your videos and others like Bernie at ATS and I learn a lot. I’ve even purchased my own4 channel PicoScope, WPS500, Pico NVH equipment, and other accessories (out of my own pocket) to help dealership technicians as best as I can. With a lot of dealerships it can be hard to be at multiple places at once with so many different technical requests that come in at times. I really enjoy helping getting vehicles fixed. Although corporate can push certain assignments that are in my opinion not needed and don’t help getting vehicles fixed it can get overwhelming to add to our workload. I’ve always prioritized getting vehicles fixed and all the non-important assignments I will push to the bottom. There is a lot to this industry and have been a Chrysler Technician before so I can understand the frustration trying to resolve an issue without the proper tools.

I worked in industrial Maintenance for over 30 years. I was the Manager and had 12 mechanics reporting to me. Sean seems like an awesome mechanic. If you have a guy like Sean asking for a tool he needs to solve a problem, you buy it! It doesn't take a rocket scientist to see the need and the value of a 4-channel scope. The problem with corporate dealerships is there is only one customer affected by the broken truck. There is no sense of urgency on their part because they can look at another day. In the Industrial world when something breaks you may have 80 people or more standing there waiting for that equipment to be repaired, not to mention the hundreds of customers not getting their orders on time. I would have ordered that scope the day he asked. Like you said, all the cost of what has been done already could have been avoided. The people in charge are showing their lack of experience and knowledge in dealing with diagnostic issues. I can't wait for the fix! They better buy Sean lunch for a month after this!!

First of all, hats off to Sean! He's a responsible and dedicated professional that should set an example for others! Crazy problem and very impressive study you made, Ivan!!! No way this could have been seen, without the 4-channel scope! Quite likely, the P0019 stems from the distorted waveform the sensor outputs, and the P0018 was just a mishap installing the timing chain, that should not have happened, if there was a proper scope in the first place, and none of that unnecessary mechanical work (courtesy of the tech support) should have been done. Can't wait for part 2!!

remember that engineers accepted the job twice with pictures and wave forms

[@JoseSilveira-newhandleforYT]

@@StagArmslower Yep. It just shows how detached they are, the parts cannon being the weapon of choice.

[@tecnaman9097]

I'm a bit surprised a main dealer didn't have a 4 channel scope in their diagnostic arsenal. As Ivan said you can't diagnose cam/crank codes without one. So how did this dealer management and the Toyota 'engineer' expect Sean to fix it without the right diag kit...yeah,when you don't know, fire! Sean is an exceptional and coherent diag technician. Good on you Ivan for what you did. 2 smart guys working together, just like you and Keith.

[@onenikkione]

they usually replace parts and get lucky, then hand the bill to the customer

[@fulf]

I have worked at main dealers in europe. We had scopes but the technicans that do fault findings never get time to do long diagnosis. (More cars more money and no time to sitt down and read how the system works and understand it) Initial times is 1 maby 2 hours. And if it is warranty they some times need to ask for more time from the warranty support After that they need to begin on the next car. (Booked cars) An because they onley have 1 lift each they cant leave the other one in the shop. I know many good technicians but they never get the chanse/learn anything that the brand dosent have a course for. And somtimes they know more than the support. And many brands have "bad' diganos software. I mean you dont get the tree of the modules so you get a picture how they are connected.

[@scientist100]

I dont charge unfortunately when I can't be for sure but being mobile is harder and customers don't understand the implications of diagnosing a car, especially for timing codes where it could very well be a stretched chain, timing solenoids (stuck open for advanced). Stretched chain for retarded codes.

[@robertsmith2956]

Even worse than the part is the 15 hrs labor charge to put it on that doesn't fix the car.

You never want a technician that knows all the answers. You DO want a tech that explores all of his or her resources to find the answers.

I agree management doesn't understand the cost savings of the right tool. I don't want to go into a long story. Had network problem at work. 6 months they fought to solve the problem. I finally convinced them to give me read only access to the switches. I brought in my own protocol sniffer . 10 minutes later I found the impossible. 2 device on the network had the exact same mac address. Showed them the capture. Told them to change out one of the device with a new oem device. BOOM! PROBLEM SOLVED. Tell Sean awesome job! He needs a to tell his boss he needs a raise!

[@chillybrit2334]

Ivan, you should coerce your pico contacts to get the tech who sent you this mail a 8 channel scope for their personal toolbox. They clearly know how to use such a thing and when. They are also on flat rate, so they are way in the hole on this but determined to resolve it for the customer but being hampered by pish poor employer provided kit. Do the right thing, costs you nothing, costs pico one scope, PR opportunities abound, one less talented thorough diagnostician leaves the trade disillusioned and burnt out. Do it. :D

[@Runco990]

When I worked at a regional repair center, I asked my boss for a Huntron Tracker. I made a very compelling argument how this tool would save many hours a day in troubleshooting time, which is why I felt we should have it. They got it for me! And it DID boost productivity immensely once you learned how to use it. TOOLS are important. The RIGHT tools are invaluable. 👍

[@markcondrey2297]

I find it hard to believe that these dealerships don’t have the proper diagnostic equipment to form an accurate diagnosis. This alone is the head of the parts cannon demon. I enjoy your work and I learn greatly from watching the way you tackle these issues. Thanks so much and God bless!

Somebody probably decided ten years ago that such "fancy diagnostic tools were for regional field expert personnel only" and any one of them who was foolish enough to apply for same...

Why would a dealership tech learn to diagnose? You can just hang parts on the car, or try swapping parts from the identical one on the yard.

[@laxbeach2381]

My dealership I get my vehicle serviced at does.

[@TheOnespeedbiker]

So the problem after replacing the starter and after chasing timing codes and replacing the timing chains (creating another problem), may very well be a chinesium CPS. So again new doesn't always mean good; especially aftermarket electrical components. The issue with strange timing issues reminds me of an Eric O video where the cam reluctor wheel had come loose.

[@moshet842]

Kudos to Sean here. You couldn't have done this without his excellent work.

[@rickblanchette]

I agree with your assessment. 99% sure aftermarket CMP sensor. Timing off a tooth not too bad we have all done it. I have had the same experience with our factory engineers as he just had. ( automated cartesian cells for electronic assembly production ). Would send us down a rabbit hole of tasks until we would deduce that they had no clue, never seen it or did not wish to give in information ( they would not always tell us everything. A Japanese thing ) even that we work for them and paid by them.

Try being a mobile tech working in the insurance repair industry 😂 traveling to a shop, doing the setup needed for a frame swap and then actually doing it then moving on to a diag on a problem caused by the body tech that plugged in two connections on a Volvo xc70 rear bumper harness that caused comms to fail after the rear hatch kick sensor and the way the system is set up that throws a code for the battery monitor sensor. I go to body shops and dealers, I went to a bmw dealer not to long ago to strip down a 2024 bmw m4 competition so they could replace the passenger quarter panel structural metal, why didn't they do it? Because it's too difficult for their dealer techs that's why. I had the entire interior including the dash, carpet harness and everything else out so they could safely weld. It's never boring and I enjoy working alone but to get 80 or 90 flag hours you gotta hustle, l best job I ever had coz I love the challenge and the pay lol

Not ever. I would never sign up for that. I'd rather buy old junk $500 cars and fix them up and sell them myself.. or something else. lol I've done that a lot with motorcycle basket cases and made good return on it... and I would get to ride them for free for a year or two; turn around and sell them for good profit in the end.

while that one was a parts cannon dealership, the one I went to for a jeep problem was ANTI parts cannon. they were too busy looking at the computer. once I got rid of the thing, it was a pure "you" problem. originally, I had bought a new battery for the jeep and the tech installed the thing backwards (the jeep had the wrong group battery in it, facing the other direction for better cable fit, and I'd bought the correct one). after getting rid of it, it turned out to be a popped fusable link! i didn't even know those still existed. this problem is what prompted me to start watching you guys' channels to begin with. there were later problems with the same vehicle (body damage, incorrect lug nuts all around, and the guy I'd traded it to swapped new wheels on, and didn't think to tighten them down to spec, having the wheel come off in mid drive, destroying the driver's fender!)

[@W.Khairi]

With this kind of code rough idle will be my first thing to pay attention to thats to isolate if its an actual mechanical problem or otherwise. Could be a bad cam in that case i would check pulse width at various points of the capture, if it is a bad cam i'd normally see big discrepancies between pulses not consistent variance. With such codes i sometimes need to physically see the reluctor wheel with a borescope to eliminate any reluctor damage ( while manually spining the engine ). Surprised u didnt count ex cam sproket teeth, as its more likely to would've jumped, cause originally the car was throwing Ex cam timing only codes not both. Normally pcms r right in determining a timing issue so this should have been a straight forward diag. I'd say Sean called the right man for help, Enjoyed it as always, Thanks Ivan.

It's amazing what rare gems you find hiding in the back woods of Pennsylvania. With honesty and integrity like that Ivan deserves all the work and prosperity he can handle. We're lucky to have him in our area.

One more thing needs checking is the timing waves to the actual cam and crank mechanical positions with scope check of pressure transducer wave to see if the timing wave is actually in time with the cam and crank. Sitting on the edge of my seat for the conclusion. Rooting for Sean👏👏👏👏

It almost seems too easy... Excited for Part 2! I wanna shim that exhaust cam position sensor, seems like it's too sensitive!

[@emalaret6]

Gret job. I love your videos.

[@mikechiodetti4482]

Every time the scope comes out Ivan proves whether or not the timing chain is off 1 or more teeth. I'm surprised those engineers didn't tell that tech to replace the engine! Part 2 hopefully will prove it.

[@agoodneighborautorepair2176]

Very nice adventure,I did work for 4 different dealers in the pass always working by pressure and big stress with problem like this one,you work long hours for low money and no appreciation from the company,that is no easy to be a technician or mechanic.. Blessings..

It's so funny that people think a snorkel intake turns a Tundra into a submarine. Nice catch in finding the differential in the width of the signal. I hope this doesn't mean you're going to move to North Carolina and join the war-room; solving the unsolvable without getting your hands dirty.

[@joychung3639]

I agree with your conclusion because at begin the guy also say some one already try to mess with wiring and change part on the truck. most of the cmp/ckp is not oem.

[@billyr9840]

Ivan, Nice ! Your Awesome Dude !

[@calholli]

Nice catch.. Always go back to the basics. The problem was even more simple than expected. (well, the original problem). Having the known good is crucial. Getting a known good from other existing cars is the genius I won't forget. If only the guy would have sent these to you BEFORE digging into that timing cover.. smh

[@jimthompson2737]

As always a very instructive video. I think you are spot on with your diagnosis. Maybe he can reset the right bank #2 cams from the top without having to take the cover off. I’ve seen some hotshot techs reset cam timing on these engines that way. Also what if the exhaust cam sensor had water in it, I know it’s a long shot but I have seen that happen.

[@throttlewatch4614]

Sean you the man for wanting to better yourself. My bets are on Ivan

[@paulsolovyovsky1702]

I always have popcorn when I'm about to watch a video. It's my whodunnit shows like NCIS, etc..except this is real life. Who needs Monk, Blue Bloods, Law and Order, I'll be watching this in syndication. Great job as always, I love the plan of action creation and root cause analysis that like House figuring out what happened to patient when everyone else couldn't.

[@tomvleeuwen]

It could still be the camshaft itself. I have seen a couple of times that somebody put a magnetic base work light on the camshaft, magnetizing it and modifying how the camshaft sensor responds. In this case, it seems that all pulses are effected evenly, so it is unlikely, but it still needs to be verified by swapping the camshaft sensor with the other bank before ordering a new one.

When the Customer used his Toyota Truck as a USS Nautilus Submarine and the hours Sean put in the best thing is replace the engine the customer is going to pay hours of diagnostic service that will be in the thousands of dollars it would have been cheaper to replace the engine .. The worst thing Toyota did was put a snorkel on their 4 by 4 trucks .. After reading how deep that engine was underwater that engine is Tost you might fix the timing issue for a while but what's next ?? Just remember Water is the Strongest Material in the world and it will destroy anything in its path including Toyota engines .. BTW great video Mr Ivan loves to see the fix and helping Sean out that was really nice of you to do so

[@vpimike2646]

Ivan, I agree it sure looks obvious that the main timing chain on bank2 is 20 deg off (2 cam teeth, since cam sprocket should have double the teeth compared to crank sprocket), but your second theory about the aftermarket CMP sensor was eye-opening to me. Clearly you have analyzed the lag and the width of the EX pulses and clearly something is out of whack. I was thinking that the timing sensor blade plate on the exhaust cam was not right for this engine, but I agree that your theory on the aftermarket sensor seems more likely. Sean needs to look at both when he goes in there. Fantastic work, with all due respect to Keith DeFazio, you are probably the most influential guru to the automotive diagnostic community worldwide!
