Got my CARSCOPE VISO today and I wont second guess anymore in spending 300$ for a MAF on a previous Nissan truck job and just by using pid’s. I was just lucky that day!🙏 Now, with your trick of a trade wisdom by DD, you’re awesome man! Thank you!💪
Hi Dan Thank you for all the videos that you showing us how to repair a car step by step PLEASE do not stop recording how to fix and repair cars I am following you from Iraq🇮🇶🇮🇶🇮🇶🇮🇶 and I really had a lot of information from you. wish and I will visit you at your workshop. Big thank you from Basra, Iraq. 🇮🇶 Note Make some funny records I like it 😂😂😂😂😂😂
Great job on the diagnosis, Dan! For electronic components I have learned that the ONLY reliable option is OEM. Even a used or remanufactured OEM component is better than a NEW aftermarket. Now I wonder how the aftermarket manufacturers test their products for functionality and calibration. Maybe they don't at all xD
The price in levs does not match what you are asking on eBay for one, so I have sent you an email. Also the company distributor here in USA doesn't seem to be listing it yet. Is it too new of a equipment? Also is it your own product made in Bulgaria or it's a clone of someone's else work like the VAS 5054A for example?
Dan your diagnose skills and equipment are absolutely amazing, added to your ability to teach anyone interested in learning, makes it perfect. Thank you again.
I’ve been a South Main Auto viewer for about 9 months. Eric O. recommended this channel, and it seems like Dan is on the same level. Dan seems to go into a little more detail, which is good.
I would be rather comparing him to ScannerDanner than the others. Those two are the best, ScannerDanner in all American cars and our dutch friend in European cars
Another job well done. I like the fact Dan, that you go the extra step and check the system before you decide to change a sensor so you do not charge your client for a part not needed (your a good honest man). I know you go in depth to explain to us how you diagnose problems, and that is awesome. Thanks for sharing.
@@Diagnosedan Yes that's true, but shops do this. In fact, a couple videos back a shop sent you a vehicle after they replaced parts that were not needed and did not fix the problem. But, you fixed it.
I can't thank you enough for the deep information you show us ! You are definitely NOT a' remove and replace' guy ! You are truly a super problem finder !
I always get away from aftermarket sensors... But sometimes you can only fit what the customer is willing to pay for... Great video again! Thanks for sharing!
That aftermarket MAF is robbing power from a poor old engine. Possibly ended up killing it due to extended lean condition. How ruthless! Always an amazing diagnosis n fix from you. Can't wait to see more coming. Cheers.
The MAF sensor signal is also used to calculate transmission line pressure control. Good way to burn up a transmission if it is fooled into thinking it needs lower line pressure than it should.
You pretty thorough, us backyarders can only do a basic scan and do an educated guess from there, but now that cheaper diagnostic equip is avail, and you given a taste of what to buy, certainly time of going down a more diagnostic path
I always learn a lot from your videos, you are a smart technician and a great teacher. The world needs more like you, honest about what you do in regards to customer paying for what they need. I like all of your videos and that funny one about dan could not fix with your kids giving you pain meds. But we know you always fix it. I also learned about OEM parts. I have a 2009 BMW with a speed sensor problem and found out get the OEM one after replacing a aftermarket one. Keep it up DAN.
Excellent video Dan sometimes the cost is the key for customers to decide between OEM or Aftermarket preferring normally the cheaper one (aftermarket), but precisely that "savings" in cost can cause "further expensive" repairs or "unexplainable" failures even when the component has been replaced with an aftermarket newone. Thanks againg for the precise knowledge shared in your channel, by the way nice tools you got there!.
Great case study Dan, it proves why we as professionals should insist on OEM parts for a proper repair. Love the MAF calculator, looks just like the one we have for our Tech Support Group Subscribers from TFA Solutions 👍
@@Diagnosedan So why do you buy crappy Nipparts? That Hyunday probably left the factory with a Bosch MAF. Why not buy a Bosch? or Hella or NGK or MagnetiMarelli or Delphi? one of these is the OEM supplier of the part, not Hyunday.
@@Diagnosedan Hi Dan. Maybe i didn't. I was focused on the tech part. Create job by the way, this is the reason of your video, to teach people the proper way to diagnose a problem. I saw a lot of comments like "I will never buy aftermarket again" and those people do not know what they are talking about. Of course there are aftermarket bad suppliers but like i said some aftermarket suppliers are also OEM suppliers (same part different box and price) One more thing. Are you sure that MAF sensor was for that model of car? parts mismatching can happen sometimes. Quick tip: check the OEM part code in an online EPC like 7zap.com or everythingbenz.com. With that code buy at your local parts store the OEM part or an alternative from a good supplier. Wish you all the best and keep up the good job
Great video dan! Learned my lesson with aftermarket sensors. In october i had someone diagnose a bad MAF Sensor so i went into autozone thinking what the heck ill slap it on there and boom it was fixed..for now. Last week( February ) i turned on my car to go to work and immediately noticed the idle jumped around and the car smelled like gas. I thought it was just acting up and it would pass so i drove on and going down the street of my neighborhood the car would jerk on acceleration almost to the point that my head was hitting the horn!! I knew something was up but decided to go on the main road and merge onto the highway to get to work. Worst freaking mistake ever. The jerking stopped until i got to around 60 mph and everything seemed fine for 5 minutes. I pushed down the accelerator and noticed i wasnt going anywhere. All the dash lights came on and i realized the fucking car just stalled going 60mph in rush hour traffic !!!!! I had to call a tow truck on the side of the road and towed it into a shop. They diagnosed it to be a bad MAF sensor!!! The same one i had put in 4 months prior almost cost me my life!! Never again am i buying Aftermarket stuff!!!
This is the main reason I will NOT work aftermarket repair shops again. Too many cheap aftermarket parts that fall short on fit and functionality. I have seen this too many times and this has caused more headaches than it's worth. Great job showing this and sharing Dan!!
DUDE LOVE YOUR VIDEOS. VERY INFORMATIVE AND LOTS OF DETAIL. I LOVE HOW U TAKE YOUR TIME EXPLAINING AS MOST VIDEOS I SEE THE GUYS EXPLANATIONS ARE TOO QUICK AND HARD FOR PURPLE TO FOLLOW. ESPECIALLY PEOPLE THAT ARE JUST LEARNING MORE ABOUT HOW TO FIX THEIR OWN CAR OR JUST FOR KNOWLEDGE. ANYHOW GREAT WORK MAN. THIS CHANNEL HAS THE BEST BREAKDOWN OF CAR ISSUES HANDSDOWN. GREAT VIDEOS NEED TO BE NOTICED
Wonderful !!! MAF calculation is impressive to me ..... Then we could figure out how much electrons and fuel needed at any given rpm and engine displacement. Decades ago JENDHAM was great seminars for around 10 years now I missed. But you are even better to understand so clear for me. MAF calculations was mystery for me with air volume and density in actual field because I've been working only on smog check ..... Thanks for everything Mr. DAN.!..!...!........
This is one big reason why I am an advocate of OEM parts, even on older cars. If outfits a new car with a sensor that's bad enough to noticably affect driving behaviour, but good enough to not trigger a check engine light, imagine what it would mean if you are the lucky one with a "good enough" ignition coil AND injector AND pump AND camshaft sensor.
Wow!...This is very good info. regarding the quality, or lack there of, regarding aftermarket parts. This is especially critical in electronic engine control replacement parts! If price is all you care about, be prepared to experience less performance & gas mileage as well as likely lower reliability. In this case...you get what you pay for! Very good content Dan. My first time on your channel & I am impressed with your attention to details & your thoroughness. GOOD Job!!!
Hello Dan, I just subscribed to your channel. Excellent work as your diagnosis is excellent; for others to learn. Thank you, for what you do! I've been a mechanic over 27 years now and, there is always something new to learn. Cheers!
You're the man Dan! Great work you do is an inspiration to all who watch you work! Plus, you have some great personality jokes! You have to enjoy what you do for others and, taking care of your beautiful family! Makes it great for everyone who watches your channel! I'm just trying to be a real person here, you do a great job! (y)
Another great video. It is fantastic how to take the time to demonstrate the difference in components, along with showing how the component, I.E. the maf sensor operates. I use your videos to teach my 11 year old grandson the techniques of working on automobiles. Keep up the great work.
Thanks dan great video that shows just how bad aftermarket parts can be it got me thinking on how many guys put those sensors and then they are left scratching their heads. I feel bad for them
I always look forward to your videos. They are professionally done with a nice presentation style. I particularly like the learning segment. Thank you for sharing.
Just found your channel about a month ago. I really like the way you explain the subject matter because I can understand and your presentation is very personable . I noticed that you are a SMA fan as well. Eric O. does a great job too. Keep up the good work and I look forward to your future videos!
Cheap electrical components gets all stuff of issues. Less money less music. The car is not running 100 % but there is no engine light. ' sometimes it is'😂 Very good professor and thank you for the video.👍
Thanks for the in-depth comparison. I have been working on cars 18 years and am mostly self taught. I watch mostly for enjoyment because you remind me of the guys that help mentor and mold me into being the technician I am today. I love checking out the wide variety of Diagnostic tools and Software you use. I added this video to my favorite folder, to show people the difference in quality between parts. When I was an Audi Technician in the states, I would work on friends and family cars and I would always get them OEM parts for their vehicles. I would get a discount of course going thru our parts guys. People would still complain about cost. I will send this to the next person who wants to be cheap. I am currently deployed as Defense Contractor, working on newer model US Military Vehicles. So in my spare time, I have to live vicariously through you. I will be finishing out my contract and heading home, which is in Berlin, Germany. Where I have small hobby garage, where I plan to just buy and flip cars. I travel once a year to Amsterdam, next time I am in the area I will send you message. I would love to come by and check your shop out and have a coffee if your available.
Hey Dan just wanted to let you know I just fixed the honda finally today. It was the throttle body gasket. The previous owner didn't replace it correctly so it was leaking. The car still has many problems but now at least it's drivable thanks a bunch.
Hello Dan, I just found your channel and this video may have just saved me some money. My 2017 2.2 turbo diesel has given me a p2196 code. O2 sensor signal biased/stuck rich bank 1 sensor 1. In Chile, car parts are very expensive and mechanics who know what they are doing are scarce. My scanner doesn't give me any data on how well the O2 sensor is functioning but it does tell me what the MAF sensor is reading. Using a website that allows me to calculate how much air is flowing into the motor and comparing it to the MAF sensor data, I found the MAF sensor reading from 2 to 6 g/s more than calculated. I ran the test 3 times using a different rpm and each time the sensor read high. Looks like I need a new MAF sensor. Thanks Dan
I love how you show The wheatstone bridge going into a comparator that's also used as a differential amplifier this is what electronics is about you are a legend in the automotive industry world you are on the Michael Jordan of automotive
“We don’t want to make the customer pay for our mistakes.” Bravo! I wish all mechanics had that philosophy. Sadly, none I’ve ever dealt with have. Excellent video!
Another super video, many many thanks. Especially because I'm a beginner and already had contact with Tommy of tfasolutions about the carscope viso. But now I can see it in real action and I like it very much because of the help a beginner like me can get from it. I hope to see much more of that scope in your videos!
Goedenavond Danny, Weer een super duidelijk verhaal, in combinatie met Electude echt goed gedaan. De vergelijkende test als conclusie, Top Groeten Hans
Great video dan Thanks for sharing I think the only thing we need to bear in mind is some aftermarket parts brands have OE or OEM inside there own branded box and are good quality There are many big parts company’s that buy for the likes of Bosch, PIerburg, Valeo etc and just put in there own packaging
Your right, but it's very hard to get to know who made the parts or if they meet specifications. For that we need to rely on the experience of our part supliers.
Thank you for this. May I say that many millions of people have zero financial choice between oem and aftermarket. When money is a deciding factor, brand choice is important. Many aftermarket sensors are good, have a warranty, and are reasonably priced. Would you consider doing a video on what aftermarket brands are the best bet? Also, on many older cars, aftermarket is the only available option. Thanks again!
HI Danny. honestly when I saw your first Video about Launch scanner I was not impressed with your video, but after watch more of your videos, I start enjoying them and see you as cool person. keep up the good work. thumb up for you.
That Auto Ditex would be a great way to start using a scope . The help section is an added bonus . To see the difference on the aftermarket parts is an eye opener . This is a critical part and you can SEE it impacts performance . Imagine having several parts like this on the same engine and having drivability issues . If each sensor is off - how much ? - total it up and you are chasing your tail with issues . You would have to have known good OEM data on each sensor to know if it's operating properly . And name brands are not always a guarantee . I just watched Eric O . diagnose a new Dayco timing belt that was off by several degrees and setting a code . And those parts with no name and a plain box could be suicide . The only thing I will buy in a plain box - is an air freshener ! Great diagnosis and lesson .
Depends the difference in price and whether you can return them should they not work IMO. Lets be honest. Some OEM parts prices are crazy stupid.Reason why cheaper knock offs.
@@patbutete1722 the cost of labor out ways the price difference,I am a tech and shop manager, and we warranty our repairs for 3 yr/36k miles, any profit will be lost having to pay a tech to rediagnose and replace the part again, and then we eat the added cost of the oem part
@@flatratemaster That's a different argument altogether.Sure.I wouldn't want sub standard parts fitted on my car without my say so.Having said that, el cheapo knock off replacement parts have a significant role play.After all they are part of the reason why most cars that no longer have factory support sill on the road ..No?
Hi Dan - it has taken a while but you have grown on me. I have disagreed with your logic a couple of times but most of the time we agree. On this video I questioned why you decided to use the Autosim to check the continuity on the plug when a simple multi meter would do the job, but after confirming continuity you then went on to demonstrate that by injecting a signal you can prove 100% that everything from the sensor plug all the way back is working properly. So good move. The reason it took me so long to accept your channel is your hands. Having been through many presentation courses I appreciate that standard wisdom recommends that we use hand gestures to help get our message across. Personally I think you need to tone it down a bit for people like me who have a phobia of windmills. Apart from that really minor issue - I now enjoy your videos and I am slowly making my way through the videos on your channel. For my own personal use I have ordered an Autel MK808 - will I be happy with it?
wow a 171 in the making! ok I gram per liter then top it off with a half would be close all leon sent you was a test light? I got a gold watch! a great guy that leon is! great vid dan as always
Great demonstration of the importance of using OE sensors. I've been caught out in the past myself with aftermarket sensors not being fit for purpose. It makes you wonder how they get away with it 🤔
That's a fantastic tutorial in great detail! I wish you went into more details of the common failures of MAF sensors, as they usually don't completely fail but start sending wrong values to the ECU. Especially on Diesel engines, those platinum wires get covered with dust, grease and soot. In my book, first procedure for those before replacing the MAF is to try and clean it up with MAF cleaning spray, although it's often only a temporary fix.
Super video as always Dan! Having been burnt with aftermarket sensors you are money ahead buying OEM. I will however use Bosch if available. I'm going right now to check out this scope. Thanks again!
Thank you for the comparison between OEM and Aftermarket. Have found Aftermarket may sometimes be as good as OEM but have never found Aftermarket to be better. When reputation counts, OEM is best.
How could anyone give you a thumbs down ? Thanks Dan just learning all this, I have vcds and have been doing ok on with it with forum back up and from supplier but just bought mp 808 your a big help , scan tools have to be backed up with a lot of modern diagnosis knowledge
Es hermoso ver alguien que sabe de su trabajo, aquí donde vivo muchos mecánicos cambian cosas hasta ver que den con la correcta y a veces ni así quedan.
Thanks for the description of how the MAF sensor works. I always read the part of attempting to keep the same temperature or current on the sensor it never made sense. I just knew higher voltage meant more airflow. But knowing that its an NTC resistor in a bridge makes everything so much more clear. It makes the failure modes a bit more obvious and you can see how different things will affect the performance of the sensor.

A great test,It would be interesting to compare two OME sensors just to see how close they are.
@@10Tug Great idea!
Another interesting test would have been to see the deviation on the short and long term fuel trims with both MAFs to see how much they altered.
More comparisons like this would be great. Thanks for a very interesting video Dan. 👍😉

Excellent description. It's nice to see someone who understands electronics in its fundamental level in car diagnosing.

Thanks for the in-depth comparison. I have been working on cars 18 years and am mostly self taught. I watch mostly for enjoyment because you remind me of the guys that help mentor and mold me into being the technician I am today. I love checking out the wide variety of Diagnostic tools and Software you use. I added this video to my favorite folder, to show people the difference in quality between parts. When I was an Audi Technician in the states, I would work on friends and family cars and I would always get them OEM parts for their vehicles. I would get a discount of course going thru our parts guys. People would still complain about cost. I will send this to the next person who wants to be cheap. I am currently deployed as Defense Contractor, working on newer model US Military Vehicles. So in my spare time, I have to live vicariously through you. I will be finishing out my contract and heading home, which is in Berlin, Germany. Where I have small hobby garage, where I plan to just buy and flip cars. I travel once a year to Amsterdam, next time I am in the area I will send you message. I would love to come by and check your shop out and have a coffee if your available.
Hey Dan just wanted to let you know I just fixed the honda finally today. It was the throttle body gasket. The previous owner didn't replace it correctly so it was leaking. The car still has many problems but now at least it's drivable thanks a bunch.
Well done!
Hello Dan,
I just found your channel and this video may have just saved me some money. My 2017 2.2 turbo diesel has given me a p2196 code. O2 sensor signal biased/stuck rich bank 1 sensor 1. In Chile, car parts are very expensive and mechanics who know what they are doing are scarce. My scanner doesn't give me any data on how well the O2 sensor is functioning but it does tell me what the MAF sensor is reading. Using a website that allows me to calculate how much air is flowing into the motor and comparing it to the MAF sensor data, I found the MAF sensor reading from 2 to 6 g/s more than calculated. I ran the test 3 times using a different rpm and each time the sensor read high. Looks like I need a new MAF sensor. Thanks Dan
Great video Dan,nice to demonstrate after market is not oem
Sometimes aftermarket is Oem😉
Unbelievable difference. These aftermarket parts are just not good enough. Great video Dan!
Thanks for watching!👍
Love your videos, always so very well produced.
Great that you took the time to explain the operation of the mass air flow sensor circuit.
Your welcome!😊
I love how you show The wheatstone bridge going into a comparator that's also used as a differential amplifier this is what electronics is about you are a legend in the automotive industry world you are on the Michael Jordan of automotive
“We don’t want to make the customer pay for our mistakes.” Bravo! I wish all mechanics had that philosophy. Sadly, none I’ve ever dealt with have. Excellent video!
🤣🤣 Thanks Rob👍
Another super video, many many thanks. Especially because I'm a beginner and already had contact with Tommy of tfasolutions about the carscope viso. But now I can see it in real action and I like it very much because of the help a beginner like me can get from it.
I hope to see much more of that scope in your videos!
It's a great scope when you are not experienced!👍
Ohh boy oh boy, say NO aftermarket sensors. This could result in end less diagnose in unpleasant driving.
Great Job 👍👍
Another great vid Danny. Lesson of the day... don’t use aftermarket sensors, They r more trouble than their worth. All the best!
Thanks for watching!
Goedenavond Danny,
Weer een super duidelijk verhaal, in combinatie met Electude echt goed gedaan.
De vergelijkende test als conclusie, Top
Groeten Hans
Bedankt Hans! 👍💪
Dan you are the oracle , a joy to watch 🙌🏻
Great video dan
Thanks for sharing
I think the only thing we need to bear in mind is some aftermarket parts brands have OE or OEM inside there own branded box and are good quality
There are many big parts company’s that buy for the likes of Bosch, PIerburg, Valeo etc and just put in there own packaging
Your right, but it's very hard to get to know who made the parts or if they meet specifications. For that we need to rely on the experience of our part supliers.
Thank you Dan. Good job. I appreciate your videos. Have a blessed and safe week.
Thanks Billy👍
Thank you for this. May I say that many millions of people have zero financial choice between oem and aftermarket. When money is a deciding factor, brand choice is important. Many aftermarket sensors are good, have a warranty, and are reasonably priced. Would you consider doing a video on what aftermarket brands are the best bet? Also, on many older cars, aftermarket is the only available option. Thanks again!
Outstanding presentation, perfect sequential diagnosis and chronological demonstration 🇦🇺👍
HI Danny. honestly when I saw your first Video about Launch scanner I was not impressed with your video, but after watch more of your videos, I start enjoying them and see you as cool person. keep up the good work. thumb up for you.
Dan that is a fantastic video great content and very well presented. Keep up the good work
Thank you!😊
Thanks for comparison Dan, a real eye opener on aftermarket parts same as that ABS sensor, less air calculated less fuel injected less power produced
👍💪
A another valuable lesson from you, brother Dan. Thank you!
Glad You like it!😊
@@Diagnosedan It's only your fault!😊👍
Wow massive difference. Great video Dan thank you
Yes it's amazing!
Professor Dan the man does it again.. great info DAN. Super detailed. Love it. 👍👍
🤣🤣 Thanks from Dan the Man 👍👍
I am very happy that we fixed it together.
As always. Topnotch video dan. Very cool stuffs and lessons. Thanks
Thanks Jack!😊
It's a pleasure to watch your videos Dan, keep 'em coming!!
Thanks Sander!
That Auto Ditex would be a great way to start using a scope . The help section is an added bonus . To see the difference on the aftermarket parts is an eye opener . This is a critical part and you can SEE it impacts performance . Imagine having several parts like this on the same engine and having drivability issues . If each sensor is off - how much ? - total it up and you are chasing your tail with issues . You would have to have known good OEM data on each sensor to know if it's operating properly . And name brands are not always a guarantee . I just watched Eric O . diagnose a new Dayco timing belt that was off by several degrees and setting a code . And those parts with no name and a plain box could be suicide . The only thing I will buy in a plain box - is an air freshener ! Great diagnosis and lesson .
I am new subscriber but I have to say I really appreciate the quality in your channel very very professional
That is why I don't use aftermarket sensors, just too much of a crap shoot if they will work right
And in this case the difference in price was only 10€ 🤔
Depends the difference in price and whether you can return them should they not work IMO. Lets be honest. Some OEM parts prices are crazy stupid.Reason why cheaper knock offs.
@@patbutete1722 the cost of labor out ways the price difference,I am a tech and shop manager, and we warranty our repairs for 3 yr/36k miles, any profit will be lost having to pay a tech to rediagnose and replace the part again, and then we eat the added cost of the oem part
@@flatratemaster That's a different argument altogether.Sure.I wouldn't want sub standard parts fitted on my car without my say so.Having said that, el cheapo knock off replacement parts have a significant role play.After all they are part of the reason why most cars that no longer have factory support sill on the road ..No?
Except for all those times the aftermarket sensor is just the OEM sensor in a different box.
Car manufacturers don't manufacture electronic sensors.
That's a good point on the aftermarket sensor... Thanks, Dan!
Your welcome!
Wow, Dan An area of aftermarket Parts I never thought of and the power output is going to be drastically reduced. Cheers again.
Hi Dan - it has taken a while but you have grown on me. I have disagreed with your logic a couple of times but most of the time we agree.
On this video I questioned why you decided to use the Autosim to check the continuity on the plug when a simple multi meter would do the job, but after confirming continuity you then went on to demonstrate that by injecting a signal you can prove 100% that everything from the sensor plug all the way back is working properly. So good move.
The reason it took me so long to accept your channel is your hands. Having been through many presentation courses I appreciate that standard wisdom recommends that we use hand gestures to help get our message across. Personally I think you need to tone it down a bit for people like me who have a phobia of windmills.
Apart from that really minor issue - I now enjoy your videos and I am slowly making my way through the videos on your channel.
For my own personal use I have ordered an Autel MK808 - will I be happy with it?
wow a 171 in the making! ok I gram per liter then top it off with a half would be close all leon sent you was a test light? I got a gold watch! a great guy that leon is! great vid dan as always
Thanks! Yes Leon is a great guy!
Again a nice lecture and fix. Thanks Dan
Excellent information from start to finish. Very informative!
Great demonstration of the importance of using OE sensors.
I've been caught out in the past myself with aftermarket sensors not being fit for purpose.
It makes you wonder how they get away with it 🤔
I have no idea and the price difference was only 10€
Excellent vid. I have experienced non genuine sensors being out of range. Fit a genuine dealer sensor and alls good!
Thanks for watching!👍
Just came across your channel. You are a fantastic teacher. Thank you so much for your in depth explanations.
That's a fantastic tutorial in great detail! I wish you went into more details of the common failures of MAF sensors, as they usually don't completely fail but start sending wrong values to the ECU. Especially on Diesel engines, those platinum wires get covered with dust, grease and soot. In my book, first procedure for those before replacing the MAF is to try and clean it up with MAF cleaning spray, although it's often only a temporary fix.
I've got a video on cleaning a Maf.
It's called "Diagnosing an engine without using fault codes"
Super video as always Dan! Having been burnt with aftermarket sensors you are money ahead buying OEM. I will however use Bosch if available. I'm going right now to check out this scope. Thanks again!
I always try to use known good brands.💪
Excellent video as usual - I'm learning so much - thanks for taking the time to put those vids together!
Thank you for the comparison between OEM and Aftermarket. Have found Aftermarket may sometimes be as good as OEM but have never found Aftermarket to be better. When reputation counts, OEM is best.
Yes there are good aftermarket parts.
Thanks for all your videos. number one channel.
Thanks!😊👍👍
Ali Bhai where are you from...
How could anyone give you a thumbs down ? Thanks Dan just learning all this, I have vcds and have been doing ok on with it with forum back up and from supplier but just bought mp 808 your a big help , scan tools have to be backed up with a lot of modern diagnosis knowledge
Es hermoso ver alguien que sabe de su trabajo, aquí donde vivo muchos mecánicos cambian cosas hasta ver que den con la correcta y a veces ni así quedan.
Great job Mr Dan .
Thanks!
After the nice theory of operation , I was hoping for a tear-down to the faulty MAF sensor.
As usual, very informative video. Thanks Dan.
Thanks for watching!
Another great video Dan. I’m liking that scope more and more. For the price seems like a good deal.
It's not a Gmto or Pico but i like it!
Diagnose DAN okish.... ha ha nice work buddy stay well
🤣🤣 Thanks Mike👍👍
Thanks for all your videos, you mean it is better to use oem parts than aftermarket parts? Your explanation is understandable God bless you Dan
It's best to use parts that meet the right specifications whoever made them😊
Thanks for the description of how the MAF sensor works. I always read the part of attempting to keep the same temperature or current on the sensor it never made sense. I just knew higher voltage meant more airflow. But knowing that its an NTC resistor in a bridge makes everything so much more clear. It makes the failure modes a bit more obvious and you can see how different things will affect the performance of the sensor.
