Hello! I am a mechanic from New York documenting my journey as I begin going full time on my mobile mechanic business. I have been working on cars since 2014 and have developed a speciality for Volvo as I spent a total of 7 years working at a Volvo dealership. Here I will share as much of my journey as I can while I diagnose cars throughout my area :)
Reading Camshaft and Crankshaft signals using an Oscilloscope!
In this video I walk you through the actual process of retrieving a waveform. It is obvious that you need to check the cam and crank sensor.. though it is not always so obvious WHERE you are going to pull those signals from when you are a flat rate mechanic! I try to give you the tips that help me get to the reading as quickly and efficiently as possible.
I mentioned the free wiring diagram resource, if you have any requests for particular information, leave a comment below!

A great way to test a car battery! Pico 4425A Diagnostics
Переглядів 486Рік тому
In this video I demonstrate how to use an oscilloscope to generate a comprehensive starting & charging system test. The oscilloscope used is a Pico 4425A. This is the beginning of my journey with UA-cam. I will be making a lot more helpful videos.

Customer's concern is that his car stalls at red lights when his AC is turned on! AutoZone told him he has a bad ground!! Tag along with me while we find the problem & repair it ! :)
Thanks for taking the time to share this information!!
you're welcome. I am going to be making more videos soon. is there anything specific you would like me to cover?
Hi, I'm using Launch x431 creader elite v2.0 and it has CMP no pulse and CMP noise, I saw some intermitten no pulse at value 4-5 at CMP B. Is it possible to figure out if the CMP B sensor is bad with those? Thanks!
It's not possible unless you can swap the sensor with another. I don't believe what you have is an oscilloscope.
You may be able to swap with another cam sensor on the engine if they're similar
@@TheCarDoctoreth that's what I'm thinking that I can do. It updates the value every second and that's it, no think like yours. So, CMP no pulse value can be part of the design?
@@NguyenDuongVu it's likely the cmp sensor is bad but make sure all of the connections are ok as well
@TheCarDoctoreth I see. Got it. Thanks a lot. Not many have the knowledge to share these complicated stuff like you! Appreciate it!
Best video ever
would like a wiring diagram for my 2007 2.4L Chevy HHR
Hi I can help you just give me time to get my website back up
What scanner would you recommend for someone with a diesel pickup that wants to do things like reset the nox sensor?
🎉🎉🎉
Great video but unfortunately can't reach your website. Can you do anything about that?
Working on that today
too bad about your website. the gatekeeping on information is getting crazy
I am going to fix it. I didn't realize this video got views
Great video
Excellent easily the best on the web for this alternator
I try the link but dosent open
Yeah, unfortunately, your website doesn’t work. Do you have an alternative site?
thanks!!
Can you add the wiring for a 2007 Dodge Caliber?
your website does not work too,
i have been hustling to learn this scope thing but the way and manner the posters display their information here, make it seems like we the beginners we have idea about scope already and then they start to go straight taking us to be already pro on scope. so far so good, i have watch a lot of information and still am hustling to get it but am getting some though, CAN Bus information i have gotten myself some understanding, i have hantek2d72 ...
Just did an alternator replacement on a 2011 XC7 today. Not the worst repair I've ever done but still a pain in the ass.
Thanks for this excellent video. For those of us with right-hand drive vehicles, access is more difficult because the brake master cylinder and reservoir are located on the same side as the alternator. I had to remove the intercooler (and cover), the heat shield over the exhaust manifold and the rear intercooler bracket. I also removed both nuts holding the brake fluid reservoir to the bulkhead so that I could move that around as needed. That gave me just enough room to get the alternator past but it was very tight and a lot of wiggling / rotation was needed. Also, if you are a clumsy oaf like me and you pull the small wires out of the back of the connector while trying to remove it, the grey wire goes at the top with the blue one below. If you are lucky, the wires will push back in and still make a connection. I used a ring spanner on the tensioner with a breaker bar as a lever between the back of the engine and the spanner. I then tied a rope around the breaker bar to hold it in place.
been a wrench and shop owner 45 yrs. No disrespect but every video I watch about scope use never gets into basic adjustments of the scope itself, how to actually do it.😢 It's always assumed we already know how to make adjustments. I have a 2 channel snap-on scope . A lot of times I can't even get a pattern to show up. Usually I end up load testing the ckt. between sensor and pcm, if wiring checks out good, then I figure it's either the sensor or pcm, since sensors are usually pretty cheap I put a new one on. Most times that fixes problem. There I said what a lot of us end up doing. Back before scopes that's how we all did it. Guy's would probably use scopes more if trained properly. I've watched a ton of videos and have yet to find one that slows the roll and explains basic scope functions and adjustments! I am trainable, the US navy taught me how to operate nuclear reactor on submarine. If any body out there can teach me I'd be a willing student😅
I really back your comment, most posters dont teach the real thing, they all think we re pro and they start talking talking talking about
No disrespect to you Brother and the 1st Reply, this is the first time I have seen this channel and I would not expect a technician channel, I have not looked around so just off the cuff here, but I would expect a DIY or low level mechanic channel to teach the basics and not a higher level Tech or Diag Channel. DAMN, I just looked closer at the channel and its dead, but I stick with my level of training based on the level of the channel, cheers. Check out the Teacher ScannerDanner for some guidance when it come to learning at different levels. I dont follow DIY and I was a trained Electronics Tech on TVs and Stereos, etc right out of High School with the use of a scope in the early 80s.
I will make a new video very soon demonstrating how to setup and I can provide a guide for parameters for general sensors so you can actually get a waveform
"promo sm"
I'm really struggling with the belt tensioner - even tried going through wheel well - there just does not seem to be enough room. Almost at the point that I may remove motor mount to make enough room. Do you have tips and tricks to help out?
what tool are you using? I would recommend using a long wrench if you have one available, in the video I'm using a gearwrench 86114. I don't remember if it's a 14 but that's the type of wrench I used. may be tough to fit a ratchet from what I remember
@@TheCarDoctoreth I got it done with a crescent wrench and a long c-clamp held against control arm and end of wrench (from wheel well), then I pulled belt over steering pump - phew... I will definitely be ordering a long wrench, as I do not want to risk a stripped head for next time.
@@TheCarDoctoreth Do you find the (Gearwrench 86114 / 14mm 120XP™ Universal Spline XL) spline version is better and prevents head stripping compared to regular 12 point?
@@pingpong9656 yes definitely, the spline version is a lot better
@@pingpong9656 spline xl flex head is the best wrench set
What kind of tablet is that?
surface pro 7. I don't recommend it to be honest.
@@TheCarDoctoreth Because of the way the pico performs on it? Or just the tablet in general?
@@nservice1625 the pico performs great but I just think the overall reliability of the device could be better. if you want to use it all day it will overheat and have problems with the screen going black and not displaying anything.
Nicely done! Hope to see more 👍 I still rather use a carbon pile load tester, But that's just my preference.
those are much better than the average tester out there today lol. Thanks man I plan on making more content
Great video
Thank you!!
Extremely informative. I appreciate you taking the time to document this for us. Well done young man. Phenomenal work!!
Thank you so much bro! you are the man!!!
