Been a long time Paul you may or may not remember me. However, I remember when you first started youtube videos. It's a blessing to see how far you've come. You inspired me to open my own shop when I got laid off as a diesel mechanic. That was 5 years ago and still going strong. I apply the same basics to diesel engines also. Thank you for all you do and be blessed!
It’s inspiring to watch experienced professionals who take pride in what they do and are SO good at what they do that they can brake it down to inform even the most inexperienced tech. THANK YOU
Today instead of movies I am watching your channel while fixing Fords in my shop. Good entertainment I like how it feels like I am there with you diagnosing the car. Love the channel bud you deserve twice the subs you have!
so call "techs" & "mechanicals" needs go back to basics and learn them and aply it. half of the time thats the problems and quit been part changers...this is why danner so good lol ;)
Who cares about the thumbs down as long as it does not stop the video. This guy is an excellent teacher takes his time to pass on his knowledge to all who will listen. The information that he gives is super incredible.
Dude !!! That was flipping awesome! ....I had same set up on a 1999 for tarus...ground on pcm but I thought pins or conne tots was bad so I pulled them Off ....low and behold !!!....most of all the connections on female side was tarnished just like this ....replaced all the connecteors and boom ! Started that car right up ....43,000 miles for 300 dollars. Plus my time over 3 or 4 months ....just didn't give up and didn't let it get the best of me ....thank you for up load and I appreciate you doing this for a freinds friend .....I work on cars but not for a living and I just love messing with any motor that comes .y way .......Marcus in west Texas....sweet job bro. Sweet job !!!
DiagnoseDan Nice to c u here. The D men. I have been watching him for years. What about u? He really got me started using a scope. I have one of those old MT 2400. Great tool! It even does 240 AC for house work
Wow. It’s like I just went home and Paul is teaching in his super style. I’ve watched this vid several times. Each time I learn more. Cool use of the MT2400. I bought one. They r great!!
Hi, I used to love using the Vantage around 15 years ago when I was an auto/electrical tech. Loved the tool, it was well made (in the US :) ) and at one point I actually thought of making it rechargeable since it was quite power hungry. I did use the pro version a couple of times, but did not like it as much as the original. BION but I had a couple of these, in the cases with all the accessories, and sold them on Ebay thinking I may never need them again. Recently I had a problem (p0325) with an 2003 Honda Element of mine an wanted to see the waveform of the knock sensor - I still work on cars now and then. Obviously you still love using the good old MT2400, but what would you suggest I look into getting to be able to view a wave form? I still use a power probe and was wondering if you had used the new Power Probe PPTM01AS (Maestro), or shall I go for a scope like the Pico, Hanteks, Signstek DSO203 or a multimeter/scope like a Liumy? PS I don't mind using a laptop/tabet - I have a bunch of Toughbooks. Have a great New Year. :)
If you are here to learn, you’re in the right place. There is no better automotive teacher, this side of the pond. The people who hit thumbs down must be looking to polish headlights or air up their tires because that’s all their brains can handle. Thanks for the instruction Mr. Danner.
To be nice when I troubleshoot a car in 5 minutes and the owner ask why I figured it out (like many times) and my shop didn't? I say they deal with a lot of cars or not their specialty. Defend those who are not present.
Defend those who are not present? I don't know about that but it is good to assume the best of people. However if money exchanged hands for a job not properly completed and later more issues maybe major issues arise is just plain bad. I usually say I'll see what I can do for you and try not to mention anyone else because for all I know it could've been the customer who was screwing around trying to fix something. If they have receipts then it's fair play only because I don't want my people to be screwed by a shoty mechanic who accomplished nothing but took money for a job well done. People need to know sometimes mechanic really are out to screw you I've seen it myself firsthand. My cousin lost his Honda accord because a mechanic wanted his payment for the car which he never fixed and the mechanic ended up keeping the accord in the end. He never even moved the car from where we left it on the far end of the lot. This is what got me to want to learn so I could help my family and friends stay on the road safely while not getting screwed by Chris (the mechanic) and losing their transportation. I definitely had plenty to say about that mechanic lol.. I tell everyone he is no good. In the end the court gave him the car due to taking space in his shop even if he hadn't touched it.... that rat bastard!
Hello Paul, I'm a 59 Yr old fart who was an hgv tech ( semi truck to you & your US bros) for 30 years. Turned my hand to everything but electrics. Seems to me, I was born with an open ground in my head with a 12v sensor feed to the dark place where electrical understanding is stored. The bulb just never lit. I have been watchin & lovin your vidz for a while now and thanx to you the grounds are being fixed one by one and the reference signal voltage is slowly coming down. You're an absolute fkin genius with a mind like an ECM. I'm blown away by and still trying to comprehend just how much stuff is inside your head. Just nipped in to pass on to you a humungous thank you and major gratitudes for sharing that most valuable asset a human being can have is knowledge. You're amazing man‼️ You keep makin em we'll keep watchin em. Happy & healthy life to you & your family.
Alec Nemeth - I'm on my 50's, thankfully for me, my long time deceased father in law. Started me on the "dark magic" of the electrical side of vehicles. He himself started as a 12 old apprentice kid building batteries. Different times for sure. By then I already had a quite decent mechanical background. That simply add the cherry on top of the cake. ;-) One of the details I never forgot was, in general, to keep contacts clean, grounds in particular immaculate. I can't state enough how much it kept me clear of "car troubles" over the years. Since one way or another I'm always messing up with "mechanical stuff". Keep that on top of my to do list. Worth every penny. Except for family or friends who seem to take advantage of it. LOL 😂 I also thank ScannerDanner for his knowledge sharing. Big Thumbs up. Cheers all
Thank you for this video, I am just converting a loom at the minute and was failing to understand why there was a normal set of grounds and sensor grounds. This video has cleared up the wiring diagram perfectly and I can only thank you for that
My first instinct was a wire-to-wire short to battery power, so it was a surprise to see this was caused by a poor computer ground. As you say, if the computer ground is bad, the computer voltage regulator that produces the 5V standard will have no reference baseline to produce exactly 5V. It was really helpful to hear your remark that every time you've seen it, the problem is not a short to power, it's a bad ground. That's where experience trumps book knowledge, invaluable. Thanks!
Wow! You just made my weekend! Can't wait til Monday at work to check what I have been working on. you just made this whole 12v. to 5v. Bad ground. So easily understandable. I'll definitely be checking your webpage Thanks and keep up the good work.
Again, beautiful to show how a logical approach makes sense and works. I know you wouldn't normally be working on am electrical system with power applied. Only thought is mention that whenyou have grounds from different systems connected together like that but not connected to ground, they will seek a lower resistance (via current flow) through the other floating grounds. That could potentially damage the more fragile circuits e.g. say a headlight seeking ground through the computer lifted ground wire. Of course the headlights aren't on I'm just using that as an example. It may have been one of those mercy repairs for a friend but look at the great opportunity it provided for a great example of trouble shooting. Thanx for you videos!
Some of the best automotive lessons on UA-cam. Great job explaining some invaluable information. Thank you very much, & please keep the informative knowledge flowing so we can keep absorbing proper, practical, effective, not to mention profitable information. I can't say enough. Thank you sir.
Excellent demonstration of why knowing fundamentals is so important. I can't imagine how much time or the amount BILLED in vain! Money that could've gone to maintenance or tires. .. great video Paul!
Brilliant. ...The result is all that matters. Love the way you explain your thoughts as you go along...... I'm a lapsed motor mechanic/ electrician....comng back to the game and finding all this Electronic/computer stuff on cars is pretty daunting...But you are inspiring me to resolve these problems.... I kinda knew the 5v had to be present at all sensors (Like washing machines!) So finding it at almost battery voltage... had to be a "grounding" problem somewhere. BUT.... That was a mega hint on the Fords: No Check Engine light..... Thanks for that. Big saludos....And thank you.
It's very cool how there are layers to what you're teaching. I bought your book and have watched a ton of your videos and once I really got serious about getting better I found more content within videos I'd already watched. I don't think I was ready for that understanding until now but better understanding of principles, finding direction early and just plain old experience is making me a better technician thanks brother, I'm not on your level but I'm getting there. 👍
I like this description "layers" It truly is this. It all builds and connects with each other, eventually :-) Thanks for the comment and it does my heart good to hear how much this has made a difference for you.
The man I am no electrician but I sure admire what you did and I was riveted to your video keep up the good work buddy I'm glad she started for you once again you are the man. Keith Kuhn
The information you provide in your videos is awesome. I've been looking for this type of explanation that you provide so I can figure out the cam issues I'm dealing with. All the other video's I've seen seem to stop explaining problems once they've solved their issue where you continue to talk about other problems that we could be dealing with and how to diagnose them. Thank You! Keep up the great video's!
Great job of troubleshooting - loved it throughout. Was a good tutorial for me as relates to the 5 volt reference - a few days ago I finally found out where the batt voltage was reduced to the 5 volt ref. :) I see the parallel application of that 5 volts, and it is readily available at the "easy to get to" sensors. Many thanks,
I have started to lean towards wire piercing also. I have no desire to second guess connections or even worse, the possibility of crossing two terminals and frying the computer. Liquid electrical tape is a lot cheaper!
🙂 sweet, lots of rusty thingys tho, thats neat i didnt know about that weird ground plug. On a 96 blazer i had something similar, theres a big fat wire connector that goes between the Computer in the engine bay and the interior fuse box, it was a tiny bit loose, very hard to tell that it was loose, i left the key on and started wiggling wires, when i wiggled near the connector i heard the fuel pump kick in heehee ☺️ Oh and on Hondas go ahead and at least replace the negative battery cable often, its a weak wimpy thin gauge cable that gets corrody and uses these tiny 10mm bolts, one on the trans and one on the fender, give it a nice new cable and bolts, yay! 😍🚗🎃👻💀🏡
I bought your book years ago. Best money I ever spent. The history of that cars “attempts to repair”, compared to your relative ease and quickness of the same exactly demonstrates your skill as an instructor/diagnostician. You are the best. Thank you for sharing.
When I saw the computer laying on the footwell... I thought it was going to be one of those when it is better to run away... and yet you stood your ground. Great!!!& and thanks for taking us along
Hi Paul, Thanks for sharing your knowledge, skill and experience. Would you please explain how bad computer ground would raise the voltage. if you have covered this in your book please let me know where it has been covered.
It is no different than any other circuit with a bad ground. No current flow = no voltage drop. The ECM board itself has no ground, so all power coming in and circuits trying to operate cause the entire board ground voltage to rise. Hope that makes sense. I could draw it better than describe it. I'm sure I do in one of my playlists I provided here in this description. The ground circuit problems one. There's like 6 videos in that playlist. I think you'll get a better ideas when you see some more. Thank you!
My 4age engine isn't starting when the engine is hot when cold it's starts quite fine and if I press the gas it starts up I change plug wires, plugs, external coil but it's still not ok
Crazy right? It is no different than any other circuit with a bad ground. No current flow = no voltage drop.

Great video professor! That experience to know where to look for that bad ground...that’s invaluable! It probably saved you an hour to go look at wiring diagrams etc. Thanks for sharing! 👍👍👍
This is where you see the dues being paid. The one that took you a long time the first time and lost money, you've been making money from for the last 20 years.
@@ScannerDanner Immigrants! Now that I've addressed the boneheaded side of the equation let me just say I hope these kids know how lucky they are to have you as their teacher. BTW my 88 Impulse uses the TPS switch. It only senses idle and WOT. Funny thing about it is normal operation is no pump prime before cranking and OBD1 DTC 12 is normally always stored to indicate that RPMs have been too low at some point during the current key on condition...Duh!
@@ScannerDanner awesome video thank you sir!! I seen this go the other way where a cam sensor on my jeep was reading 1.6v on the signal wire..after verifying I had my full 5 volts supply.. I've learned so much from you..keep em coming
I watched your video as a starting mechanic about a year ago when I was just starting, I didn't understand then but after watching it again with some mechanical experience it's a GREAT VIDEO SCANNER DANNER YOU DA MAN...
I stumbled on to this video and I love how well you explain what you are doing. I have never put the time into understanding electronics but now you got me hooked. I plan on learning from your teachings.
sorry to be offtopic but does anybody know of a way to log back into an instagram account..? I was stupid forgot the password. I love any tips you can give me!

@@ScannerDannerto My 2009 Buell Ulysses and many other Buell with aluminum frame have computer ground issues caused by unseen with the naked eye resistance caused by dissimilar metal of the computer grounds and that dam aluminum frame . I was getting a DTC light lean O2 only at 70mph + . Light would go out when slowing down below 70mph . Cleaning aluminum ground points where computer grounds we're located was the solution. still will have issue sometime in the future and will have to repeat cleaning of aluminum because of dissimilar metal affect. Bad design
@sparky obrian Sorry man, I misunderstood you. Forgive me. I've just been dealing with trolls all day on Facebook Your comment was valid in that regard. I took it as you saying I was wasting my time showing this fault.
@@ScannerDanner my apologies also, im too quick tempered- the biggest character fault of all, believe me. I wasnt clear either, Im constantly trying to make a trouble shooting job fast and accurate and not loose money, its hard in my field, hence its important to know when to pass on a job.
It's always nice to see someone fix a problem by using their head instead of just guessing at stuff. It's really sweet to fix a problem in a few minutes that everyone else has not managed to repair for the last two weeks. Nice job.

Looks like Michigan there. Great video. I've been a Mobile Mechanic here in Ann Arbor for the last 15 years and a Mechanic for 30 now and one things certain I am always learning something new!! I love being a mechanic and really enjoy jobs like this, like you said, once solved they pay in spades. I use parts buckets for my tools and fasteners to stay organized (busing tubs or dish tubs) it helps on jobs outside of the shop. I miss my quick strippers (we used to use HEI advance springs to fine tune them when I worked at Roush, ha). Anyways I'll pick up your book and I'm sure I'll learn from it!!
Hello paul. . Can u give me some help at the forum.. see what u think i bout 2012 chevy traverse with the p0090 with a new fuel pressure sensor. Thank you.

Working on a 2015 sierra AC. Found many burned plugs, bad grounds, and a bad fusebox. Git 5v on reference, 12v, and 7v on pressure switch. Checked for all problems I could find in forums and solved a handful of issues with things other than the ac. Thank you for this video, now I have a new direction to look. My biggest fear is replacing the pcu and still getting no power through compressor clutch
Had a 1987 Murcury Topez ( essentially a Ford Taurus ) and if I did not know how to work on it myself , I could not have afforded to keep it. When it ran - it ran well , but had SO MANY issues in the seven years I owned it. Replaced the cylinder head twice - because , in my opinion ,the cooling system was barely adequate . The first time I replaced the head - the water pump had failed and overheated the engine, the second time I replace the head , a rock was slung through the radiator , my wife did not see the engine starting to overheat - so the engine overheated again. Occasionally wondered ,after this experience, why automotive engineers don't design engines to automatically shut down BEFORE overheating from either coolant or oil ( lubrication ) issues. Hell , they now have so much automatic this automatic that - surely with engine ECU's ( computers ) this can be engineered for ALL engines 🤨✌️✌️
another great vid mr danner, i nearly got my ass kicked last month by a french 508, abs and stability control light on, code said missing rear wheel speed signal but on the live data the signal was there, i just couldnt find anything wrong on the wiring. then out of the blue a code came up with front wheel speed signal missing while i was working on it, again the live data showed a speed signal, i didnt get what the hell was going on until i found the passengers foot well was full of water and had got into one of the computers. i was not expecting that i can tell you as it was summer.
I was like just poke the wire and u did lol bro who cares what people think when your the one having to diagnose the problem, we do whatever we gotta do to make sure we leave nothing out !!!
That was helpful. I had a 2002 Dodge 1500 with a no start, checked the ref signal at cam and crank sensor, none. Checked continuity to computer, it was good. Replaced the computer, and all was well. Keep the vids coming.
I had a problem on that exact same ground in my 94 Mustang when I had it. Only it wasn't the connector it was the bolt not staying tight because somehow the threads wouldn't tighten it when the bolt was all the way down. Ran a tap and replaced the bolt car was fixed.
hey Scanner Danner first of let start by saying thank you for all the knowledge you pass along.....i have 2 seperate vehicles one is 2011 dodge nitro /3.7 i can jump starter and truck runs but not when using key....havent checked grounds yet thats next... 2007 chrylser passifica 4.0 doing almost same thindg wont crank with key ...i can jump starter but it wont startchecked all grounds i can find even replaced some with 4 gauged wire...i noticed butterfly in ETBS doesnt move i check for voltage at TBS have 5volts kinda confused both vehicles were running at one time then just stopped if you have any idea please help
Back in 1992 i was 20, this same Taurus lost 5v reference, i replaced ecu and still missing, disconnected all sensors and 5 v show up, dang egr backpressure sensor was melted. Lesson learned.ford from the 90's was my best teachers
Hey Whats going on Scanner Danner.....Great video and very informative so thank you very much! I have a question regarding the computer ground because Im trying to make it make sense (Im working on a 94 Ford F150 btw). Early in the vid you said that sensor grounds work by all sharing a ground that leads to the computer, then the computer grounds them externally right? If so, Im thinking the area you're working on near the battery is where the computer is grounded, which in turn grounds all other sensors? And if that be the case, Im trying to figure out what the flickering and fluctuations of voltage mean and how it relates to sensor grounds, computer grounds or a 5v reference of other sensors and why you were getting 11 volts on those TPS wires? Can you help me understand?
Danner Scanner, I am a bit confused about the 5volts reference signal, PCM negative signal. I noted you use a test light with a positive input signal as trigger voltage. But, I am a bit confused about using a test light as a jumper to provide a signal because is 12vdc and I computer uses smaller voltage as reference voltage and trigger voltages. Not sure if you understand my question. Thanks
Amazing. The idiot parts changers- should be ashamed of themselves. They made a mockery out of themselves- and they know it!. Thanks again Paul for helping Us up and coming Technicians.
People really don't understand how long it takes for us to replace something. If it's just myself it's going to take me awhile to fix even the simplest of things because there's thing I need to do before even working. Unplug battery, visually inspect engine bay for obvious problems. Just testing the fuses takes forever one by one. Even a simple spark plug & ignition coil or wire replacement is gonna take me 20-30 minutes to do correctly & safely. I always take the time to make sure any car I fix or repair, I would drive & I do this checklist after I'm done billing someone time. I usually never have any doubt about a car & 99% of time I would trust my child in car but if there's ever anything I missed I fix it without charge because it's on me or if I notice something else dangerous I inform customer & let them decide if it's not dangerous to not fix it e.g. radio or cosmetic damages. Point being, it takes us quite a long time to find out what exactly is happening in car especially if we have to go in after other mechanics have been through it & put everything back in & then look for problem.
hey man my 3 pin wires for both cam sensors both read 11.8v, 11.5v, 3.5v i think the middle wire 11.5v is the reference instead of a 5v, but looks like 3.5v on the ground wire? its a bmw 318i 2003 n42 with EML light on and codes P0015 Camshaft Position - Timing Over-Retarded & P0366 Camshaft Position Sensor "B" CIrcuit Range/Performance (Bank 1) could 3.5v on the ground throw these codes and make the car shake super rough at idle 700rpm. when i accelerate over 1000rpm it smooth out alot the same errors stay in the computer when i swap the intake cam sensor with exhaust cam sensor would you have any tips :D
just a short backstory. car was running perfect. i was driving home and saw the EML light come on for first time in my life i pulled over and turned the car off. then it would just crank but not start the road service guy first step was to spray starter fluid in the throttle body while he told me to keep the pedal to the floor and back off slowly the car started but it sounded hollow like the engine had no oil in it and soon as i let the pedal off the floor it lost rpm and stalled
i got the car towed off the main road to a nearby mechanic who told me there was no compression, blown head gasket and to swap the engine after watching youtube videos i tested the compression myself and every cylinder was 190 psi i got a bafx reader and saw 2 cam sensor codes + 2 02 codes P0050 H02S Heater Control Circuit (Bank 2 Sensonr 1) & P0056 H02S Heater Control Circuit (Bank 2 Sensonr 2) when i cleared the codes the car started first time and i drove it home. since i switched the cam sensors around the 02 codes have gone but the cam sensor codes keep coming back
i cleaned both oil solenoids and tested them with a 9v battery they both clicked and i cleaned the throttle body didnt know anything about cars until this happened really appreciate your videos on youtube hopefully the chain didnt jump teeth when i floored it with starter fluid and the problem is just a ground wire im not sure how to investigate it further yet for my car ill watch this video again and look more up on youtube if you or anyone has tips pls let me know!

Hi, I used to love using the Vantage around 15 years ago when I was an auto/electrical tech. Loved the tool, it was well made (in the US :) ) and at one point I actually thought of making it rechargeable since it was quite power hungry. I did use the pro version a couple of times, but did not like it as much as the original. BION but I had a couple of these, in the cases with all the accessories, and sold them on Ebay thinking I may never need them again.
Recently I had a problem (p0325) with an 2003 Honda Element of mine an wanted to see the waveform of the knock sensor - I still work on cars now and then. Obviously you still love using the good old MT2400, but what would you suggest I look into getting to be able to view a wave form? I still use a power probe and was wondering if you had used the new Power Probe PPTM01AS (Maestro), or shall I go for a scope like the Pico, Hanteks, Signstek DSO203 or a multimeter/scope like a Liumy? PS I don't mind using a laptop/tabet - I have a bunch of Toughbooks. Have a great New Year. :)
If you are here to learn, you’re in the right place. There is no better automotive teacher, this side of the pond.
The people who hit thumbs down must be looking to polish headlights or air up their tires because that’s all their brains can handle.
Thanks for the instruction Mr. Danner.
To be nice when I troubleshoot a car in 5 minutes and the owner ask why I figured it out (like many times) and my shop didn't? I say they deal with a lot of cars or not their specialty. Defend those who are not present.
I try to remember this. Sometimes I can't though because of some really horrible stuff and thousands of wasted dollars
Defend those who are not present? I don't know about that but it is good to assume the best of people. However if money exchanged hands for a job not properly completed and later more issues maybe major issues arise is just plain bad. I usually say I'll see what I can do for you and try not to mention anyone else because for all I know it could've been the customer who was screwing around trying to fix something. If they have receipts then it's fair play only because I don't want my people to be screwed by a shoty mechanic who accomplished nothing but took money for a job well done. People need to know sometimes mechanic really are out to screw you I've seen it myself firsthand. My cousin lost his Honda accord because a mechanic wanted his payment for the car which he never fixed and the mechanic ended up keeping the accord in the end. He never even moved the car from where we left it on the far end of the lot. This is what got me to want to learn so I could help my family and friends stay on the road safely while not getting screwed by Chris (the mechanic) and losing their transportation. I definitely had plenty to say about that mechanic lol.. I tell everyone he is no good. In the end the court gave him the car due to taking space in his shop even if he hadn't touched it.... that rat bastard!
Hello Paul,
I'm a 59 Yr old fart who was an hgv tech ( semi truck to you & your US bros) for 30 years. Turned my hand to everything but electrics.
Seems to me, I was born with an open ground in my head with a 12v sensor feed to the dark place where electrical understanding is stored. The bulb just never lit.
I have been watchin & lovin your vidz for a while now and thanx to you the grounds are being fixed one by one and the reference signal voltage is slowly coming down.
You're an absolute fkin genius with a mind like an ECM.
I'm blown away by and still trying to comprehend just how much stuff is inside your head.
Just nipped in to pass on to you a humungous thank you and major gratitudes for sharing that most valuable asset a human being can have is knowledge.
You're amazing man‼️
You keep makin em we'll keep watchin em.
Happy & healthy life to you & your family.
Thanks so much Alec! So cool the hear this kind of feedback
Thanx to you the bulb is slowly switching on.
Alec Nemeth - I'm on my 50's, thankfully for me, my long time deceased father in law. Started me on the "dark magic" of the electrical side of vehicles. He himself started as a 12 old apprentice kid building batteries. Different times for sure.
By then I already had a quite decent mechanical background. That simply add the cherry on top of the cake. ;-)
One of the details I never forgot was, in general, to keep contacts clean, grounds in particular immaculate.
I can't state enough how much it kept me clear of "car troubles" over the years.
Since one way or another I'm always messing up with "mechanical stuff". Keep that on top of my to do list. Worth every penny. Except for family or friends who seem to take advantage of it. LOL 😂
I also thank ScannerDanner for his knowledge sharing. Big Thumbs up.
Cheers all
Good one mister Danner thanks for the video .
Thank you for this video, I am just converting a loom at the minute and was failing to understand why there was a normal set of grounds and sensor grounds. This video has cleared up the wiring diagram perfectly and I can only thank you for that
My first instinct was a wire-to-wire short to battery power, so it was a surprise to see this was caused by a poor computer ground. As you say, if the computer ground is bad, the computer voltage regulator that produces the 5V standard will have no reference baseline to produce exactly 5V. It was really helpful to hear your remark that every time you've seen it, the problem is not a short to power, it's a bad ground. That's where experience trumps book knowledge, invaluable. Thanks!
Thank you for likening my comment. I all ways watch you since back in the day.Your content is the best.Thanks.paul.
Wow! You just made my weekend! Can't wait til Monday at work to check what I have been working on. you just made this whole 12v. to 5v. Bad ground. So easily understandable.
I'll definitely be checking your webpage
Thanks and keep up the good work.
Again, beautiful to show how a logical approach makes sense and works. I know you wouldn't normally be working on am electrical system with power applied.
Only thought is mention that whenyou have grounds from different systems connected together like that but not connected to ground, they will seek a lower resistance (via current flow) through the other floating grounds.
That could potentially damage the more fragile circuits e.g. say a headlight seeking ground through the computer lifted ground wire.
Of course the headlights aren't on I'm just using that as an example.
It may have been one of those mercy repairs for a friend but look at the great opportunity it provided for a great example of trouble shooting.
Thanx for you videos!
Hey Paul why don't you bring it to your class that's a good test.
Some of the best automotive lessons on UA-cam. Great job explaining some invaluable information. Thank you very much, & please keep the informative knowledge flowing so we can keep absorbing proper, practical, effective, not to mention profitable information. I can't say enough. Thank you sir.
Loving your videos! Really opening my eyes to things I “thought” I had an understanding of. Thank you!!
Excellent demonstration of why knowing fundamentals is so important. I can't imagine how much time or the amount BILLED in vain! Money that could've gone to maintenance or tires. .. great video Paul!
Thanks Cuba! And thanks for having my back on FaceBook
@@ScannerDanner Anytime! You're a good person with a beautiful heart. Undeserved punishment.
Same to you sis
Brilliant. ...The result is all that matters.
Love the way you explain your thoughts as you go along......
I'm a lapsed motor mechanic/ electrician....comng back to the game and finding all this Electronic/computer stuff on cars is pretty daunting...But you are inspiring me to resolve these problems.... I kinda knew the 5v had to be present at all sensors (Like washing machines!)
So finding it at almost battery voltage... had to be a "grounding" problem somewhere.
BUT.... That was a mega hint on the Fords: No Check Engine light..... Thanks for that.
Big saludos....And thank you.
That was a really cool case. Your always spot on with the commentary Paul.
Scanner danner my amigo
Grest diagnoses. Old school ways always do the job.
It's very cool how there are layers to what you're teaching. I bought your book and have watched a ton of your videos and once I really got serious about getting better I found more content within videos I'd already watched. I don't think I was ready for that understanding until now but better understanding of principles, finding direction early and just plain old experience is making me a better technician thanks brother, I'm not on your level but I'm getting there. 👍
I like this description "layers"
It truly is this. It all builds and connects with each other, eventually :-)
Thanks for the comment and it does my heart good to hear how much this has made a difference for you.
The man I am no electrician but I sure admire what you did and I was riveted to your video keep up the good work buddy I'm glad she started for you once again you are the man.
Keith Kuhn
Thanks Paul your the number 1 of automobile diagnostics in youtube God bless you 👍👍👍
The information you provide in your videos is awesome. I've been looking for this type of explanation that you provide so I can figure out the cam issues I'm dealing with. All the other video's I've seen seem to stop explaining problems once they've solved their issue where you continue to talk about other problems that we could be dealing with and how to diagnose them.
Thank You!
Keep up the great video's!
A Paul are you ever going to do a video with Eric the car guy. again. ?
I would love to!
Great job of troubleshooting - loved it throughout. Was a good tutorial for me as relates to the 5 volt reference - a few days ago I finally found out where the batt voltage was reduced to the 5 volt ref. :) I see the parallel application of that 5 volts, and it is readily available at the "easy to get to" sensors. Many thanks,
Prime example of how a backprobe can lead one astray. It's so very simple to seal a microscopic pin hole when piercing. 9:00
Exactly Keith!
I have started to lean towards wire piercing also. I have no desire to second guess connections or even worse, the possibility of crossing two terminals and frying the computer. Liquid electrical tape is a lot cheaper!
Prime example of when to pierce
🙂 sweet, lots of rusty thingys tho, thats neat i didnt know about that weird ground plug. On a 96 blazer i had something similar, theres a big fat wire connector that goes between the Computer in the engine bay and the interior fuse box, it was a tiny bit loose, very hard to tell that it was loose, i left the key on and started wiggling wires, when i wiggled near the connector i heard the fuel pump kick in heehee ☺️ Oh and on Hondas go ahead and at least replace the negative battery cable often, its a weak wimpy thin gauge cable that gets corrody and uses these tiny 10mm bolts, one on the trans and one on the fender, give it a nice new cable and bolts, yay! 😍🚗🎃👻💀🏡
I bought your book years ago. Best money I ever spent. The history of that cars “attempts to repair”, compared to your relative ease and quickness of the same exactly demonstrates your skill as an instructor/diagnostician. You are the best. Thank you for sharing.
Thank you Andrew
The sweetest sound in the world. When your car finally starts. I use small wire nuts.
When I saw the computer laying on the footwell... I thought it was going to be one of those when it is better to run away... and yet you stood your ground. Great!!!& and thanks for taking us along
When I saw the computer on the floorboard I thought it would of been a Honda
thanks for the video and them cool ass words of wisdom.smart man

Lol
You didn't want to mess with it but you owned it like a boss. Good work and thanks for posting this stuff.
70 Dollars an hour to work on your car , 150 Dollar an hour , if You worked on it First
This was many years ago but the sign read, hourly, 30, 40 if you watch, 50 if you help.
Excellent job. You repaired a car that everyone else condemned. It ran and sounded pretty damn good. A tip of the cap to you
Hi Paul,
Thanks for sharing your knowledge, skill and experience. Would you please explain how bad computer ground would raise the voltage. if you have covered this in your book please let me know where it has been covered.
It is no different than any other circuit with a bad ground. No current flow = no voltage drop. The ECM board itself has no ground, so all power coming in and circuits trying to operate cause the entire board ground voltage to rise. Hope that makes sense. I could draw it better than describe it. I'm sure I do in one of my playlists I provided here in this description. The ground circuit problems one. There's like 6 videos in that playlist. I think you'll get a better ideas when you see some more. Thank you!
@@ScannerDanner Thanks a lot for your reply.
My 4age engine isn't starting when the engine is hot when cold it's starts quite fine and if I press the gas it starts up
I change plug wires, plugs, external coil but it's still not ok
It sounds flooded. Check coolant sensor and also fuel pressure and fuel pressure regulator
"I'm just going to get it working for now"... Red green translation. "it's only temporary unless of course it works"
Thanks Paul. God bless you. Cheers.
Fantastic explanation. I love it when the job seems hopeless but turns out to be a dead simple fix! Thanks for sharing your knowledge, sir.
I am not a mechanic but learn a lot from your channel. Why was the voltage 11+ volts at the ground wires? how did those bad wires cause that?
Crazy right? It is no different than any other circuit with a bad ground. No current flow = no voltage drop.

@@ScannerDanner makes sense - thought that was the answer but thankful for your expert description! Thanks for all you do! If I were younger and looking for a career I would go to your school/videos etc and enjoy the challenge of auto diagnosis!
Dude ur one of the best mechanics ive ever watched....I enjoy the hell outta ur videos....youve helped me figure things out a lot....keep it up man...
Where is cale the singing camera man?
At school
Great video professor! That experience to know where to look for that bad ground...that’s invaluable! It probably saved you an hour to go look at wiring diagrams etc. Thanks for sharing! 👍👍👍
This is where you see the dues being paid. The one that took you a long time the first time and lost money, you've been making money from for the last 20 years.
A great day when i see a scanner danner video.
Btw another thumbs down..good greif..who's the troll..😲😲😲
Got in influx of new ones from FaceBook lol
@@ScannerDanner Immigrants! Now that I've addressed the boneheaded side of the equation let me just say I hope these kids know how lucky they are to have you as their teacher. BTW my 88 Impulse uses the TPS switch. It only senses idle and WOT. Funny thing about it is normal operation is no pump prime before cranking and OBD1 DTC 12 is normally always stored to indicate that RPMs have been too low at some point during the current key on condition...Duh!
@@ScannerDanner awesome video thank you sir!! I seen this go the other way where a cam sensor on my jeep was reading 1.6v on the signal wire..after verifying I had my full 5 volts supply.. I've learned so much from you..keep em coming
those with a learning disability lol
Thank you very much for the nice video very well explanation I learned a lot with the video.Well done, keep it up.
Absolutely brillant
I watched your video as a starting mechanic about a year ago when I was just starting, I didn't understand then but after watching it again with some mechanical experience it's a GREAT VIDEO SCANNER DANNER YOU DA MAN...
Thanks Paul 👏🔧
I stumbled on to this video and I love how well you explain what you are doing. I have never put the time into understanding electronics but now you got me hooked. I plan on learning from your teachings.
Awesome! Thanks so much
Where do we find the book

Mister sd u is d boss i like how u does go down 2 d bone. Even down 2 d ground 2 find d problem.i am 65 yrs an lived in T'DAD.I WISH I COULD COME AN LEARN TRADE WITH U. SO WEN I ASS ON AN D MAKER ASK ME WHAT I DID WIHH MY LAST FEW YRS, I WILL TELL HIM I LEARN AUTO ELECT& MEC WITH SD😂😂😂
time to walk away, it would be cheaper to scrap n replace
labor is labor.
Or just watch and learn something. It was a no cost fix.
Edit## read below, this was a misunderstanding on my part.
@@ScannerDannerto My 2009 Buell Ulysses and many other Buell with aluminum frame have computer ground issues caused by unseen with the naked eye resistance caused by dissimilar metal of the computer grounds and that dam aluminum frame . I was getting a DTC light lean O2 only at 70mph + . Light would go out when slowing down below 70mph . Cleaning aluminum ground points where computer grounds we're located was the solution. still will have issue sometime in the future and will have to repeat cleaning of aluminum because of dissimilar metal affect. Bad design
@sparky obrian Sorry man, I misunderstood you. Forgive me. I've just been dealing with trolls all day on Facebook
Your comment was valid in that regard. I took it as you saying I was wasting my time showing this fault.
@@ScannerDanner my apologies also, im too quick tempered- the biggest character fault of all, believe me. I wasnt clear either, Im constantly trying to make a trouble shooting job fast and accurate and not loose money, its hard in my field, hence its important to know when to pass on a job.
Thanks brother. It's hard to gauge intent through text on a screen sometimes.
It's always nice to see someone fix a problem by using their head instead of just guessing at stuff. It's really sweet to fix a problem in a few minutes that everyone else has not managed to repair for the last two weeks. Nice job.
This is Awesome. Your videos have inspired the many viewers and Absolutely, Genius Electrical Mender and Know Your Professional Work!! Thank You and Want to Have the Premium. You Tube videos bring that inspiration to watch. Thank you for that too. Hope it works for me. Old School same issue but have to know system. Hmm, Fords!
Looks like Michigan there. Great video. I've been a Mobile Mechanic here in Ann Arbor for the last 15 years and a Mechanic for 30 now and one things certain I am always learning something new!! I love being a mechanic and really enjoy jobs like this, like you said, once solved they pay in spades. I use parts buckets for my tools and fasteners to stay organized (busing tubs or dish tubs) it helps on jobs outside of the shop. I miss my quick strippers (we used to use HEI advance springs to fine tune them when I worked at Roush, ha). Anyways I'll pick up your book and I'm sure I'll learn from it!!
Hello paul. . Can u give me some help at the forum.. see what u think i bout 2012 chevy traverse with the p0090 with a new fuel pressure sensor. Thank you.

Hi scanner danner love your videos. I have had P38 dreaded range rover 2ooo1 started with faulty crankshaft censor then battery drain and now not run for a year had the AA out to it no look and mobile mechanic with no luck only said no signal at the crank sensor I am going to take on bord what you have shown thanks. ?
First Question when Troubleshooting.... WWSDD? What Would ScannerDanner Do? Second Question.. Refer to Question 1
Danner
Here is the answer
Look ford is out of car building
Bcz of garbage junk cars
So is chrysler,,gmc, saab,hummer,olds,pontiac,amc,
Buick
Totall junk
Et
Between ScannerDanner & Eric O, they could repair 99.9% of the worlds auto issues, & that pine hollow chap also.
Amazing! Great job and thank you for sharing this knowledge! Much appreciated lessons of diagnostics!!

Working on a 2015 sierra AC. Found many burned plugs, bad grounds, and a bad fusebox. Git 5v on reference, 12v, and 7v on pressure switch. Checked for all problems I could find in forums and solved a handful of issues with things other than the ac. Thank you for this video, now I have a new direction to look. My biggest fear is replacing the pcu and still getting no power through compressor clutch
Looks like the owner of that car saw his first UA-cam video on DYI repairs and he did it! LOL
Thank you my brother!!!! Back to basics. Master the fundementals. I love your book!!!!!
Had a 1987 Murcury Topez ( essentially a Ford Taurus ) and if I did not know how to work on it myself , I could not have afforded to keep it. When it ran - it ran well , but had SO MANY issues in the seven years I owned it. Replaced the cylinder head twice - because , in my opinion ,the cooling system was barely adequate . The first time I replaced the head - the water pump had failed and overheated the engine, the second time I replace the head , a rock was slung through the radiator , my wife did not see the engine starting to overheat - so the engine overheated again. Occasionally wondered ,after this experience, why automotive engineers don't design engines to automatically shut down BEFORE overheating from either coolant or oil ( lubrication ) issues. Hell , they now have so much automatic this automatic that - surely with engine ECU's ( computers ) this can be engineered for ALL engines 🤨✌️✌️
another great vid mr danner, i nearly got my ass kicked last month by a french 508, abs and stability control light on, code said missing rear wheel speed signal but on the live data the signal was there, i just couldnt find anything wrong on the wiring.
then out of the blue a code came up with front wheel speed signal missing while i was working on it, again the live data showed a speed signal, i didnt get what the hell was going on until i found the passengers foot well was full of water and had got into one of the computers. i was not expecting that i can tell you as it was summer.
I was like just poke the wire and u did lol bro who cares what people think when your the one having to diagnose the problem, we do whatever we gotta do to make sure we leave nothing out !!!
That was helpful. I had a 2002 Dodge 1500 with a no start, checked the ref signal at cam and crank sensor, none. Checked continuity to computer, it was good. Replaced the computer, and all was well. Keep the vids coming.
Impressed! that looked like a total basket case
Thanks a Lot Amigo For Another Helpful Video Tutorial of Yours ...
I had a problem on that exact same ground in my 94 Mustang when I had it. Only it wasn't the connector it was the bolt not staying tight because somehow the threads wouldn't tighten it when the bolt was all the way down. Ran a tap and replaced the bolt car was fixed.
hey Scanner Danner first of let start by saying thank you for all the knowledge you pass along.....i have 2 seperate vehicles one is 2011 dodge nitro /3.7 i can jump starter and truck runs but not when using key....havent checked grounds yet thats next... 2007 chrylser passifica 4.0 doing almost same thindg wont crank with key ...i can jump starter but it wont startchecked all grounds i can find even replaced some with 4 gauged wire...i noticed butterfly in ETBS doesnt move i check for voltage at TBS have 5volts kinda confused both vehicles were running at one time then just stopped if you have any idea please help
Back in 1992 i was 20, this same Taurus lost 5v reference, i replaced ecu and still missing, disconnected all sensors and 5 v show up, dang egr backpressure sensor was melted. Lesson learned.ford from the 90's was my best teachers
Thanks for the interesting video! And maybe one day youtube will force people to leave a comment on why - if they decide to thumbs down.
Would have wet my pants if oil cooler blew off the cap from pressure release valve failure and big end dropped out the sump after that fell off. he he
Hey Whats going on Scanner Danner.....Great video and very informative so thank you very much! I have a question regarding the computer ground because Im trying to make it make sense (Im working on a 94 Ford F150 btw). Early in the vid you said that sensor grounds work by all sharing a ground that leads to the computer, then the computer grounds them externally right? If so, Im thinking the area you're working on near the battery is where the computer is grounded, which in turn grounds all other sensors? And if that be the case, Im trying to figure out what the flickering and fluctuations of voltage mean and how it relates to sensor grounds, computer grounds or a 5v reference of other sensors and why you were getting 11 volts on those TPS wires? Can you help me understand?
Outstanding job awesome have a great time
Danner Scanner, I am a bit confused about the 5volts reference signal, PCM negative signal. I noted you use a test light with a positive
input signal as trigger voltage. But, I am a bit confused about using a test light as a jumper to provide a signal because is 12vdc and I computer uses smaller voltage as reference voltage and trigger voltages. Not sure if you understand my question. Thanks
Amazing. The idiot parts changers- should be ashamed of themselves. They made a mockery out of themselves- and they know it!. Thanks again Paul for helping Us up and coming Technicians.
People really don't understand how long it takes for us to replace something. If it's just myself it's going to take me awhile to fix even the simplest of things because there's thing I need to do before even working. Unplug battery, visually inspect engine bay for obvious problems. Just testing the fuses takes forever one by one. Even a simple spark plug & ignition coil or wire replacement is gonna take me 20-30 minutes to do correctly & safely. I always take the time to make sure any car I fix or repair, I would drive & I do this checklist after I'm done billing someone time. I usually never have any doubt about a car & 99% of time I would trust my child in car but if there's ever anything I missed I fix it without charge because it's on me or if I notice something else dangerous I inform customer & let them decide if it's not dangerous to not fix it e.g. radio or cosmetic damages. Point being, it takes us quite a long time to find out what exactly is happening in car especially if we have to go in after other mechanics have been through it & put everything back in & then look for problem.
😂 multiple shops couldn’t fix it….more likely they saw the carnage and said “NOPE” lol.
hey man my 3 pin wires for both cam sensors both read 11.8v, 11.5v, 3.5v i think the middle wire 11.5v is the reference instead of a 5v, but looks like 3.5v on the ground wire?
its a bmw 318i 2003 n42 with EML light on and codes P0015 Camshaft Position - Timing Over-Retarded & P0366 Camshaft Position Sensor "B" CIrcuit Range/Performance (Bank 1)
could 3.5v on the ground throw these codes and make the car shake super rough at idle 700rpm. when i accelerate over 1000rpm it smooth out alot
the same errors stay in the computer when i swap the intake cam sensor with exhaust cam sensor would you have any tips :D
just a short backstory. car was running perfect. i was driving home and saw the EML light come on for first time in my life
i pulled over and turned the car off. then it would just crank but not start
the road service guy first step was to spray starter fluid in the throttle body while he told me to keep the pedal to the floor and back off slowly
the car started but it sounded hollow like the engine had no oil in it and soon as i let the pedal off the floor it lost rpm and stalled
i got the car towed off the main road to a nearby mechanic who told me there was no compression, blown head gasket and to swap the engine
after watching youtube videos i tested the compression myself and every cylinder was 190 psi
i got a bafx reader and saw 2 cam sensor codes + 2 02 codes P0050 H02S Heater Control Circuit (Bank 2 Sensonr 1) & P0056 H02S Heater Control Circuit (Bank 2 Sensonr 2)
when i cleared the codes the car started first time and i drove it home. since i switched the cam sensors around the 02 codes have gone but the cam sensor codes keep coming back
i cleaned both oil solenoids and tested them with a 9v battery they both clicked and i cleaned the throttle body
didnt know anything about cars until this happened
really appreciate your videos on youtube
hopefully the chain didnt jump teeth when i floored it with starter fluid and the problem is just a ground wire
im not sure how to investigate it further yet for my car ill watch this video again and look more up on youtube if you or anyone has tips pls let me know!
just found your 2 videos on 'Hall effect cam/crank sensor operation and testing' i think my answers gona be in them!
just updating my first comment i read my multimeter wrong the sensors have 3.5 millivolts on the grounds not 3.5 volts so back to square 1 lol
Haha. Suddenly, accidentally fixed it sounds like a bad thing! To the DiyEr, "cha chi, just fixed it!".
I’ve been following your channels for years now. It’s always great to watch you. Your approach to teaching is unmatched. Thanks to you Im where Im at today...
