I somehow feel saddened that a lot of shops would have fixed this by throwing a pedal assembly in there without knowing what was causing the issue because of the code given; this video shows evidence of how critical these sensors are and that they indeed fall out of calibration over a period of time. Good job guys!
Right , a parts changed would have seen the DTC shot a peddle at it and been on its way without even looking at live data. I’m a scope users and believe sometimes we overlook the obvious because we’re afraid to be wrong and will waste time going down a rabbit hole when the answer is right in our face. Either way great video and great demonstration on how picky these systems can be .
@@markhb3346 I agree 100%. You need to know when you're setting yourself and the client up for failure. And this is an extremely fine line too. But honestly, it took longer to do this one because we were filming. I'd say 1-1.5 hours total diagnostic time involved. And that includes re-search.
@@andrewfischer9477 understood , but I do appreciate you guys sharing this because honestly I would have graphed the APP1 and 2 PIDs and wouldn’t have even thought that little difference would be enough to fault it . Thanks for sharing that it’s very valuable and shows how susceptible these systems are to failure and they’re not very fault tolerant. But I think what the OP of this thread was stating that your typical parts changed would have seen the DTC and it’s description and just shot gunned a peddle and been right with no effort. But like what Dan Sullivan says “you only learn during the diagnostic and not the repair” and this video proves that point . I’m a new subscriber 👍👍
I’m sold on the ATS system. It’s true and continues to prove itself true; scope data is vital to success. Notice how even the manufacturer scantool software could not precisely pinpoint the fault with streamed data - a voltage overage. Well done fellas!! 👍👍
There’s an elite scope 4 at a local pawn shop, they want $795, but I’m sure I could talk them down to $500. Think it’s a good deal for someone like you, a DIYer first getting into scopes?
Absolute legendary work, guys, i got to take my hat off to you, for sticking with that incredibly difficult job, so glad you Nailed it, it gives confidence to all us rather lesser qualified techi's and average Mechanics, Much gratitude and love from the U.K 🙂
Thank you for posting this. Your videos are top notch. I'm just a DIYer who's getting into scopes. This really highlights how, at a glance this could be missed...but with some scoping and comparing to the exact threshold figures a problem was found.
Cool. Sensor two reads right in between the high and low specs with pedal fully depressed. Sensor one is just over max spec, but also fell right in between high and low specs when replaced. The code, the scope, and excellent reasoning all combined to form a diagnostic trifecta.
Crazy. Such a tight voltage tolerance, especially when the car was not running and the sensor was within spec (lots of people would have overlooked and not make the call on the sensor or maybe guess lol). Recreating the problem 100% is the key I'm taking away from this video. Thank you thank you thank you for sharing this with us.
Scopes are fantastic. Had a cruze last week with what felt like an ignition miss at WOT above 5k rpm. Scope confirms good coil trigger, injector control, and current to the coil. Current for cylinder 4 is consistently 2 amps higher - coil had overheated and melted a little plastic over the terminal for the secondary terminal which feeds the coil boot. Scope made it obvious.
Another brilliant video on an interesting subject. Without the proper documentation you wouldn't have had much of a chance in a case like this. Well done and well explained. Thank you guys. 👍
Great diagnostic approach 👌🏻 love seeing ATS videos. The stop feature built in when paired with the eScan is such a time saver esp when diagnosing by yourself on a road test.
Great idea on the white board... throwing it on the dash to remember to reinstall engine covers.😊 I always see one or two covers in every shop I have worked in, that me or someone else forgot to install. Thanks!
Hey guys love from Australia 🇦🇺 The reason why you guys saw 4.756v max at live data was because the engine might not be running And when you guys checked on scope the engine was running and the alternator was pumping voltage a little bit that's why it went over 4.8v That's my logic
I AM RE-WATCHING THIS VIDEO MANY TIMES ,,, BECAUSE THERE IS SO MUCH TO LEARN HOPE TO SEE MANY MORE AND LOOKING FORWARD TO EVERYONE THANKS SO MUCH FOR YOUR TIME 🙏🙏🙏👍👍👍
A big hello from the UK I am really pleased to find this channel, its also nice to see the extended use of the ATS scan and scope, I have one but I know of nobody else local to me that does, Pico is big here which I also have, I love the power of the scope and how by using one makes you so much more sharper and knowledgeable, I am continuously learning thanks to using a scope and watching videos like yours. keep up the great content I am looking forwards to many more from this vibrant new channel.... Btw: its nice to see and nice to see the ATS scope being shown as it was only Bernies videos that were exposing the power of it... All the best guys David (Sinclair Engineering)
Just watched all your videos and have to say very informative. Not a car guy but was a nuclear engineer from Uk working on control systems who happens to like tinkering with cars,, Have bought myself a Pico. Love watching the likes of Diagnose Dan and Ivan at Pine Hollow because of how they explain stuff. You have been subscribed to, Thanks
You guys nailed it. Thank you for the detailed explanation. (ATS scope is top notch but the legend B. Thompson needs to make it a little more affordable 😅.
I paid for the 4425a standard kit and I don't do this professionally. I got 3 scanners which my Verus also includes a scope and additional scopes. I believe shops should own scopes and accessories to prove the failure modes of the vehicles when diagnosing.
not only the voltage is back in spec, but the waveform is more a square wave and before it was more like a slight ramp to it... great job! would like to see more diagnostics with the scope.
Thank you for your time and effort to make these videos, much appreciated. You may have a look at the scanner's live data to identify specific app's or tps' by their voltage levels comparing them to the scope or dvom😊.
Really great case study, Thanks! Wow I think I'm more inclined to look at the ATS scope after watching your video then after one of Bernie's😃. One correction when you were cleaning up the waveform by processing the data you said it's like ac coupling on a Pico, I think you meant to say low pass filter.
@@andrewfischer9477 I did consider trading my 4425a for the Elite but I love the control on the Pico scope. Feels like an android vs iphone. Where pico is highly customizable and escope has predefined presets that are most likely to be used and save time on setting things up.
I had a dodge journey that set throttle body and accelerator pedal position codes. All wires checked out good to those items. The crankshaft sensor wires were shorted together causing those codes. I just used wiring schematics and volt meter to figure it out.
Please give us more info on the scope you used. Does it only work on the ATS diagnostic scan tablet or would it also work on something like the higher end Topdon (Phoenix Plus) diagnostic scan tablet? By the way, thanks for this legendary lesson. Love that you are teaching people how to do diagnostic work.
Jobs backing up that need diag I would have hooked up the scope and tried the tap test, tug test, wiggle test and look for drop outs while working the throttle before I drove the car it may have speeded up the process I wonder if the waveform would have went high? great video 👍
I’m your new follower I’m also tech doing all kind of work( diag programming, locksmith key) but not as good as you guys. Curious are you using genuine Xentry, cause when I see green cable it look like my c4 doip . Genuine xentry need to buy combo 4 years subscription and it cost like 37k that’s so much compare with the rest. Great job. Ats solution is the best for scope . Very clear explanation. You guys are best
Amazing Thanks for sharing Guy's👍 Love the diag process & logical thinking😍 I'm new to the channel & Professor's video on the BMW camshaft sensor brought me to your channel, Love your work Guy's keep up the great content👍 Stay Safe👍
Well good video on how to use the ATS scope. . But the disappointing thing is the Jack leg mechanic would have just thrown parts at it. Especially if they use the Mercedes part they would have fixed it
good DIAG. going to scope out my APP SENSOR like your team did and check my results. i have a aftermarket pedal enhancer on my jeep that goes into limp mode almost the same way. but mine is intermittent comes and goes. getting codes for APP SENSOR. thanks !
Talk about some nit picking ass diodes, a little over 100ths of a volt off may need a software tweak instead of a new sensor. Not our problem though. MB and All data definitely leaves much to be desired. Whatever ,steel sharpens steel and I appreciate every sniper in this field with the patience to share what he sees on the scope.
I seems that to work at Royalty you need to have a man bun. I see you and your son. Andy offsets this with the Michigan hat, Go Blue! I can comment because I am 35 years in and I might have a longer gray hair man bun than you. I love you content and how honest you are!
Why not just look at the scanner live data and see the sensor voltage from there, which you could also graph, instead of going through the trouble of connecting a bunch of scope wires?
It is in range or is not in range. There is no other possibilities. You are pregnant or not. Even 0,000001% over and it is not in range. The range itself was not tight at all.
There’s a link in the description. It’s called tale of knives. Make sure to use code for 5% off. People asked all the time on TikTok. They love it. Progress has had his for years as well and it holds up well!!
@@theroyaltyautoservice I know, I just asked the specific diagnostic where it measures engine vacuum, if it measures the real one or the one shown by the map?
The sad thing is, you just proved that you can never have enough information available to diagnose vehicles and you need multiple types of scan/diagnostic equipment. I quit counting decades ago when I passed $100,000!😢 There needs to be a law that all manufacturers have to make available to alldata and mitchell all information so we can do our job without guessing.
Great video. But this video shows the sad, bad truth about modern automotive industry and its unneeded complexity, especially the European. The point is that this DTC error would not even appear if the software in the car ECU was programmed to a higher tolerance for this APP sensor signal, say to 5V. As we have seen from the waveforms, hardware vise everything is OK with the system, we can say that the system is 100% correct. It is only the software triggered DTC and limp mode with no real electrical or mechanical problem.
