Toyota Engineers STUMPED?! (CRAZY Tundra P0019 - Part 1)
Автокөліктер мен көлік құралдары
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:

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 KZread 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.

Ivan is the best❤
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.
The technician that reached out to you is the type that succeeds in life 👊🏻
Ivan, I'm a diehard Toyota fan, and every car I've had has been a Toyota. I want to take a minute and just say that I have never seen such a dedicated dealership technician like Sean who goes out of his way to find a problem like this. This guy is amazing. To contact the Toyota engineers themselves to for help is awesome. I also want to say that I have never had such a crazy problem like this with any of my cars either. This tech is awesome 👌 👏.

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.

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.

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. No one can possibly know everything, and if they do they likely know very little to be honest. Cheers to you Ivan for helping this guy out. Also kudos to Sean for exploring other options when he felt it was out of control and hitting a wall.
Awesome that you are willing to help Sean. Pico Scope diag took me back to school when we used old green screen lug about scopes. 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!
Kudos to Sean here. You couldn't have done this without his excellent work.

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. 👍

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
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!)
Best teacher of scope related content bar none!! Thanks for sharing your knowledge 😎👍
I sincerely hope that tech stays in the industry! God knows we need more techs like him! This stuation is exactly why we need to change the industry once and for all.
Only 10 minutes in and I can’t wait for this saga!! Go get it Ivan!
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.

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.
Beautiful view in the back. You are a good man with a good life
The most incredible part of this saga to me is that the dealership geniuses, all the way up to the highest tier of tech support, are parts changers FIRST, and that the tech is crippled with an old, dusty PICO resurrected from a tool room bin. ATTENTION VIEWERS: Welcome to the dealership.

I was a factory rep. for Mercedes and was often sent to dealerships to help with problems the mechanics couldn't find answers to. Those engineers offering advice over the phone simply can't compare to actually being there #nd putting hands on the vehicle. Hopefully you've at least narrowed the problem down to just a couple of things to correct. Can't wait to see the results. Hope the dealership accepts accountability and doesn't charge the customer for their ineptness.

Even though I don't need a scope, having one to save the day is a blessing and as you say "worth it's weight in Gold".

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.

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👏👏👏👏

Very informative video as usual, be interesting to say what happens and if your findings create a satisfactory fix for the customer
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.

It almost seems too easy... Excited for Part 2! I wanna shim that exhaust cam position sensor, seems like it's too sensitive!
Ivan, your suspicion of the cause is reasonable. I worked at one of the oem's and would use a chart recorder which is basically an oscilloscope that puts the signal on paper to capture cam/crank signals. I'd find crazy things like the wrong year crankshaft was installed which had a different sensor tooth pattern. The pattern has more teeth for higher resolution for misfire detection requirements.
Gret job. I love your videos.
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.
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.
I've been checking my notifications for the past 12 hours waiting for the part 2 of this video....

Ivan, Nice ! Your Awesome Dude !
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.
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
OMG a bad CMP sensor the whole time! Thats going to be a tough pill to swallow if that is the case! Poor Sean! I've been there before myself a few times... You just have to take whatever you learn from the experience and hopefully improve yourself over time. I just had a Dodge Ram 5.9 Magnum come in with 113K miles and the classic internal intake manifold vacuum leak (truck cuts out under acceleration)- THis was a new problem to me and I spent 3 hours (that i can't charge the customer for) chasing this problem when all i had to do was block the PCV and check for vacuum at the crankcase breather- you can bet that I am checking that on every Magnum engine that comes in from here on out!.
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!
