Thank you for sharing your findings

Would like to see some Altima P0101 videos. I have a 2013 that keeps setting a P0101 and ECM number is not listed in the TSB for reprogramming. It did have the orange PCV/ replaced with black, cleaned Throttle body and replaced MAF. Voltage readings at ECM match service information.
We see a lot of throttle body replacement . Cleaning and idle volume doesn't seem to help. Of course all the basics must be looked at first.
Excellent video. The scope is a window to the circuit regardless of signal speed.
Agree 100% 👍
Thank you for the great info on Autonerdz. I plan on having a Pico one of these days and love the fact that this comes with support. Thank you for a great understandable video!
Absolutely 💯,
As the compression starts at ATHMOSFERIC pressure do not expect a deeper exhaust pocket. It looks ok. There is an acceptable compression leak. I would worried about INT pocket as it looks very unusual.
Seems like a weird fix. Im surprised that the pedal wiring is large enough to carry a ton of current for all those lights. Its just a relay, seems like they'd just upgrade the relay, you know, instead of creating a potential fire hazard. ;-)
Engineer's .......probably only cost 1/2 a penny more to make a better quality relay.
Shorter Adapter Hose would make a difference probably
Hi, really appreciate your honest words. I think it’s very important to be selfcritical in Diagnostic jobs. Is there a reason you use Picoscope over the eScope? And do you use 4 or 8 Channel?
I bought my picoscope over 10 yrs ago, I had not heard of the e scope then. I use a 4 channel its an older model 4423 it still performs great. I do like some of the e scope features
Its innovation however without a dealer level scan tool or subscription based scan tool (autel and alike) you wont bebable to do a relearn. Just did a timing chain on 2017 pathfinder, it can be done manually but its a pain as likenmost nissans they are finicky with the seconds. Have only relearned 1 bank.
Excellent Video!
Thank you very much!
Another great instructional video and case study. Thank you for taking the time to make this.
💯👍
2018 with the same system. Crank no start. If I unplug the crankshaft position sensor it will start and run. I thought that was interesting that it will only run when unplugged. If you have any ideas i would appreciate it. I will also note with it running and plug back in the crank sensor the bank 2 intake is stick at 42 degrees advanced
Lots of chain issues on that engine. Front bank runs the high pressure pump. Is the motor sludged or noisey?
@@CartersDiagnostics it does make a slight knocking/rattle noise when snap the throttle but nothing else. Can rev it up and no knocking or anything. Pulled the camshaft sensors and they do have sludge film on them
Do you have a pressure transducer? A running idle pressure wave should show an outa time bank. Or a cam crank correlation test? The car in the video is know good.
8 channel rocks Mr Carter.lol. These intermittent brake switch diagnostic can be a pain in the butt because it's hard to take a look at everything at one time
One day hopefully I will have the power of 8..
Good video, I 100% agree with your statement about being able to monitor multiple circuits at once, and not just for high speed readings, I was wondering what laptop you are using in the video? I am thinking of getting another one.
Its an ACER nitro 5 . Kind of an older laptop.
Please make one video for k 110 currant clamp how to custom probe in pico and wr we found this clamp
Good Demonstration on the versatility of the scope, keep making videos
Thanks. I'm gonna try and keep vids coming.
Excellent! I’ve lost count of the number of eye rolls I got from my former employer when I pulled out my scope for a problem like this. Some people are funny. Thanks for sharing this one.😎
Maybe a good thing its a "former" employer. Scope use is a reality the more its embraced more success will be had.
Welcome to my part of the world.😢 People are just stuck to their old familiar ways. Sometimes they mock even though they witness and acknowledge the power of scope use in solving defiant problems.
@@abdul-kabiralegbe5660 people don't like what they don't understand
I have worked for several of those eye rollers in the past. The parts canon business model is more profitable than paying a diag. tech. Those type of eye roller imbeciles consider us a necessary evil for when they miss every shot with the parts canon and resent us for it.
excellent find keep up the good work
Thanks, will do!
I take issue with the tsb! You've now changed the way the car is wired, and any future techs looking up a brake wiring diagram will be misled. Why not just make a more reliable relay? Seems nuts to me. Relays are used for starter enable, they seem reliable enough that you don't see starters being stuck engaged. Also... where'd the power loss come from? Does the ecm reduce power when it sees the brakes are applied in an effort to prevent the brakes from overheating? Maybe it's used to stop the vehicle from being powerbraked? my questions and issues here are regarding Nissan. As for the video and using the scope for it's multi-channel abilities, good job!!
Thanks for the comment. Not sure on why they don't make a better relay. The power loss is from the brake switch input. It limits throttle response when the switch is on.
The Pico software can run up to 50 000 seconds = >14h in a single screen, and can be set to save basically an unlimited number of screens until the hard drive is full, so it's absolutely useful for logging slow signals too. And the ability to set it and forget it, just checking what it caught later can be worth its weight in gold for symptoms you only see once in a blue moon.
Absolutely 💯, Thanks for commenting 🙏
It’s nice to know your background and how you’re able to take the time to properly spend the time on the cars. I work in a different field and it’s always felt like flat rate is a conflict of interest to me. Lots of opinions vary there so I won’t beat a dead horse or anything. Nice work on this diag and video! One thing I used a scope for recently was to find a short to ground. I put a long time base on the screen and shook a bunch of wires until I saw the amperage spike on screen. Turned out to be a bad trailer harness.
Great strategy with the scope 👏. The flat rate is good and bad. The conversation is worth having per individual IMO. If I was still a flat rate rate, no way would I make videos or spend the hours on some of the cars that I record.
@@CartersDiagnostics Agreed Mr. Carter. Flat Rate is a necessary evil in the industry for the most part BUT, after a few years when someone starts as a Tech, if you're a conscious individual you must ask yourself; do I want to become a diagnostician and really know what I'm doing, or just a good/average flat rate Technician (efficient parts changer) focused 99% on the money. I think both are necessary for the industry as a whole. IMO, a few individuals should be dedicated diagnosticians in a shop. I work in a 30 bay dealer/shop where 100% of the Techs are Flat Rate, even the 2 "Shop Foremans", and you can probably guess how good that works :(
Excited to more videos🎥 very good information
Thanks
Hope you make it YT big for your 8 channel pico.. Keep it up like this and wont be too much longer! ❤
I'm feeling those positive vibes thanks 👍
Outstanding tutorial Brilliant video Can't wait for the next video 👍 DISCERNING,Carter's Diagnostics My mentor ,Carter's Diagnostics From Nick Ayivor from London England UK 🇬🇧 ⏰️ 18:46PM Good Evening
Thanks for the continued support.
Excellent video love the scope ones. I really feel the visual of any electric issues helps see.
Agreed
So that's how the overlay works?! Sweeeet!
💯
Does that engine have a counterbalance shaft?
No
Another great video. Great lesson.
👍
I hope that Rogue is red.
Great Video Carter, i've been on the fence about getting a NVH kit for my pico, i haven't seen a lot of usage in the community, i know i get a ton of noise concerns from my customers & as you know sometimes it's hard to pin the exact issue, Do you believe this tool would be effective on suspension noises ? looking forward to more NVH videos, thanks buddy
I think it would be good for noises, I believe you need more than 1 probe so you can trianglelate the noise easier. I use the microphone alot for wind noise complaints, my hearing isn't as sharp as it was, so that helps me
Excellent diagnostic Mike! I've seen engine vibration in those 3 cylinders caused by different components. Mostly transmission mount leaking! Thank you for sharing, Mike. Good tool the Pico NVH.
The 3 cylinder has been very problematic. I've used the NVH more on those than anything at the moment. Thanks for watching
Hello Mr. Carter. I'm so glad you're back! Love your videos, just packed full of great info! Just a friendly recommendation; if you could talk your friends at Autonerds to include the Pico NVH essentials kit (PQ266) as a qualifying Kit to obtain Autonerdz subscription AND to also offer the kit at the same price as AES Wave of $2173. Autonerdz on the other hand, offers this kit for $2458 and is NOT a qualifying kit for Autonerds subscription. Thanks!
I have forwarded your comment to the Autonerdz team. Any info I get ,I will certainly post it. Or they may answer themselves. Thank you for the suggestion and your support 🙏
@startec1172 Just a tag to let you know of the Autonerdz response
Sick video. Thanks so much. I do mobile diag and programming. The amount of new bad parts even from the dealer is crazy lol.
Agreed 100%. Thanks for tuning in. I do some mobile work too. Always exciting 😀

Thanks again!
Ive used NVH and that is so powerfoul tool in goed hands. But bad thing is that you need to figure it out and do a lot of testing and comparing and...but its difficult to use tool that much in reality. I think that should be a lot more case studies with NVH so we all can learn.I found some converter shutter,diff noises with it.Engine vibrations are quite heavy to diagnose it with all that pulley diametars and crank rotations and calculations...etc...I like tool but i lack knowlege...Hope my English is ok. Goed video!!!
Should try using the ignition paddle wand from the pico kits. it will pick up keyless signals too, just like your tire sensor.
Nice , I will give it try. Thanks
Excellent video, as always! Thank you for sharing.
Thanks for watching!
@@CartersDiagnostics It is nice to have measurable vibration data. I own the advanced Pico NVH, which allows me to place four accelerometers or four microphones at different locations.
@steveanderson4553 That's cool. I just have 1. The shop has an unlocked picoscope so I can use my nvh and theirs so actually I can use 2 at a time.
@@CartersDiagnostics I was tired of the butt-wars with the customers here at the dealership. It makes it so much easier, in my opinion, to prove out normal vibrations and abnormal vibrations.
Hi Mike, good to see you back. Sorry if I missed it in the video but I know you said you checked the runout of the crank with flexplate off and it was ok but did you mention if the engine was still stiff about 180 from top dead while turning engine all by itself? Thanks.
Yes ,after separating the engine and transmission it was still a weird stiff spot while rotating the engine even with plugs out.
New new engine Wednesday 10am build? 🤔😂
@@neildeatherage2269 or late Friday
just had my first one today.
Pin fit issue? If so good find! Kinda common on these cars it seems.
I had seen your video before. It was kind of in the back of my mind as I was looking at the car. So I went and checked out this video again and then went and checked the car.
@@stephenparker8023 Cool , makes my day when people benefit from my videos
Thanks for sharing Mr Carter. Appreciate the tips
Any time!
thank you for taking the time and sharing with us that thuly want to learn!!! we really appriciated you , i have a question when do you want to isolate the crankcase ventilation systems i seen some videos were the block it thank you and i hope my question makes sence lol
I really never have a script I follow when doing advanced testing. I have some basic rules that I follow like this video. When in doubt , I would test with it blocked and not blocked and compare. My latest video (Mis-fire Fun) had pressure building in the crankcase, it never showed in the intake or exhaust pulses and I did not block the PCV sytem. It definitely showed in the crankcase test. That may have been due to PCV system design, some other engines may have showed differently. Just don't box yourself in and limit your testing. To much info is never a bad thing.
@@CartersDiagnostics thank you for your response, Also I was doing some test at the tail pipe on a 21 4runner using the wps and I was trying to get a good waveform and I just couldn't get it to were its was easy to understand or read it do you have videos using the wps in the tailpipe thanks.
I use a first look sensor for tailpipe testing, not my wps (just personal choice) the wps should work just fine if you use it it zoom mode not range mode. Most all my mis fire videos i use a pulse sensor in the exhaust and try to explain how to id the bad cylinder
@@CartersDiagnostics i will try that today car has no problems but i just want to learn how to read this waveforms and your videos are helping a lot of us that want to learn,thank you once again, if i ever need help reading a waveform can i send it your way 😅
Sure. I get lots of files sent to me. Some I can help some I can't but I always look. papaslop@yahoo.com is my email.

Good luck Mr Carter 😊
This seems to be the common trend with Nissan sensors. I work on all makes and if your not paying attention this one will go right past you. Great work brother keep it up
Thanks bro, I appreciate the support.
is it a vibration or rough feeling in car you are chasing?
Yes, very rough at idle in park/neutral.
Good luck. I like your style. Look forward to all your videos.
Thank you. I hope I get this one figured out, its a stressful diagnosis.
