- Another example of why following a diagnostic process, using the proper tools and knowledge are more productive and cheaper than guessing.

Theres a wealth of knowledge out there when you put all your heads together. Thanks for sharing
Humility, empathy and compassion. Goes a long way. Thanks for the contribution.
Just diagnosed a Lexus, exact same problem. Cleaning MAF didn't help, it got a new one. VE test is the way to go. Great video.
Great tool. isn't it?
You may not have had your PC & normal style of recording, but you hit some great points and knocked it out of the park!
You're correct, not everything is DIY, for various reasons. Lack of proper tooling, for one. Knowing limitations of your capabilities is a big deal, whether it's the lack of knowledge, experience, or tools.
Thanks Cuba. Never sure if my message comes across properly.
Thanks for video Corey. I despise oil air filters. Cause nothing but issues on MAF cars and causes gummed up throttle bodies on all cars. Most people over oil them and the excess oil blows into the intake tube the first time you accelerate.
But the advertisement says they add 20 HP and last forever. 😂😂
Surprise! I didn't need an O2 sensor. Great job and diagnoses Corey! even if it is NLA style.
The kicker is when you get a customer that doesn't understand the diag fee when Autozone already guessed at it, only to find out after an hour of diag, it really is the o2 sensor. Then the customer says "see, I told you that's what it was"
Another good one Cory. Nice find easy fix 👍👍👍 most of the time I watch videos just to learn new trouble shooting techniques. I'm never in a hurry so it gives me time to learn what my new equipment can do and by following this great group of techs I can play around with a lot of different approaches.
Taking time to practice with new equipment and looking at "known goods" is soooo important. Then, you can try unplugging/disconnecting stuff to see the affect. Pull a vacuum line to watch the affect on fuel trims, MAF and inj pulse. Stuff like that. Thanks sir. Your stickers are on the way
I agree 100% some people think that they're saving money and in long run just ends up costing them more. And those k&n air filters are nothing but trouble, not sure if that one was but it looked like it. Great video thanks for sharing.
I can appreciate folks that have the ambition to try stuff. Just know when to tap out and let someone do what they're trained to do. (before it ends up costing more). Thanks for your support sir
Legend!! 👍 I started receiving these codes on my rx350 a few weeks after re-oiling my K&n air filter. Should've made the connection but I'm an idiot. Cleaned up the maf sensor and she's back in business 😜
Awesome. Thanks for the support
Are you talking to me? LOL!!!!! I am one of those guys who tries to fix it myself, sometimes I get it right, sometimes I don't and that's when I go the Pros!!! However, because of these vids I've learnt to respect guys who work in this area and I pay them a visit with my tail between my legs. Explaining what I did and telling them that it didn't fix it. Usually we end up having a laugh
Well then, that my friend is a trifecta. You're willing to learn, willing to try and respect those that can can take over when you've realized you're in over your head. Thank you so much
Thank you Corey. Good job. Have a blessed and safe week.
Thanks as always Bill. Have an awesome week sir
right on brother love your stuff thank you for sharing your time and knowledge
And thank you for taking the time to reply. Cheers
Absolutely love the atg ve app! Best app I have 😂 this app take into count the baro reading which makes this ve test better then some of the other ve calculators.
Great work Corey!
Thank you my friend for your ongoing support and push to better myself
S & A Auto Repair anytime buddy and the same goes in return! Can’t wait for your computer to be up and editing some videos
I will be downloading that ATG VE calculator this morning. Thanks for sharing Corey! & absolutely guessing can get expensive! (I’m sure this customer will be happy)
Great Wall of stickers! All awesome people!
Excellent tool. Try playing with it on a known good vehicle. Customer was very happy. Thank you
Good video. I always want to see the diagnostic thought process. Thank you for sharing.
Thanks Andrew. I've actually had comments telling me to stop wasting time, nobodies interested in the process, just tell me what's wrong. Gotta love people. Your support is very appreciated sir
Great Diag Cory. Video was perfect turned out great, keep em coming.. Jay
Thanks Jay. Appreciate your support sir
Soooo Well Done
Point(s) well taken
Thanks a bunch man!
Great (one shot) Video!
Thank you so much sir.
Great job Corey. Thanks for sharing! 👍
Thanks my friend
For Lexus RX 330 there’s a Technical Service Bulletin for this fault (applies to a specific list of VINs) and it’s not the MAF sensor. See TSB 2004-07-29
Good seeing you been a while totally agree always good to have a check and see if you can get the input from others and getting the experience from doing it for a while always helps. I come from pre TH-cam and yes I had friends in the industry but also they were my competitors they just were not as forward to divulge information so I had to learn from the school of hard knocks. Let me tell you it puts hair on you’re chest quite quickly. What I don’t like is when I went to school they thought you how to check voltage how to do this and how to do that but really never sat us down and show us normal read outs and make us memorize or remember generally what you should be seeing in a normal situation. Also when I went to school carburetors were still very dominant maybe that is why teachers had no clue what info to give out. Anyhow just to say sometimes making a bad call can open up you’re eyes and make you look further Into things and lucky you’re friend knows a good guy like you. I have seen many a garage or even dealer that would of changed the 02 sensor and then would of said we changed the sensor like you instructed us but it didn’t fix the problem would you like for us to look at the problem? Then who knows what shpeel they would of told this customer knowing that this customer knows very little about diagnosing. Long story short it’s good to find a guy that you can trust and maybe get some info if you are a back yard warrior or a weekend warrior trying to save money 💴. Always good to see you keep up the good stuff
Yes, the old days were very competitive. No info, bad info and lots of mistakes. There's a whole new way of teaching now with some very talented instructors out there. Don't memorize...analyze, is the motto. known good readings are nice, but understanding what the data is saying is the goal. Yes, there are a lot of parts canons being launched at shops everywhere. Guessing is their #1 diag tool and it's something that needs to change. No back yard warrior here, 33 years in the business, licensed and registered repair business. Appreciate all the input sir. Cheers
What do think about everything you just spoke about. With no air coming out of the tail pipe?
hey corey, as live vids are the best. Yeah the DIYers think the scan tool tells you what the problem is but its just the symptoms. I will get some stickers off to you across the pond for your toolbox. cheers dave
And I will send some back to you. Thanks for the support.
Hello! I have a 2010 RX 350 with P0171 P0174; at idle, long term trims are +30% and short term trims are +10%； when I rev up to 3000 rpm, Long term trims are still +30%, but short term trims become around 0%; I have no idea what the problem could be.!
I’m getting the same codes on my 2006 RX330. Just ordered a OE MAF & going to clean the throttle body. Did this help on this one? Check engine lights comes on & off car seems to be running completely fine, might be a little weak in power but runs fine. Hope this works for me 😄
Nice real world scenario of what we have to deal with... we have had people insist on something (replace specific part) and then blame us that it did not fix what the complaint was. SMH
The lack of understanding from the public crosses borders and languages. The struggle is real and never ending
I understand having someone replace a specific part. The customer is paying, so they decide. However they should NEVER complain if that doesn't fox the problem.
Great job COREY. HAVE YOU CONSIDERED escan great generic tool because of fuel trim and sharpshooter features thanks be well
That is a fantastic tool. Probably a perfect tool for this case. I do not have it.
Do you think having a gap from my air filter box not closing all the way will cause check engine light?
Yup
I have the same problem. What is trem that ypu are referring to? Also if anyone can explain how the diagnosis is done ?
Great video very informative. Thanks
Nice diag Corey
Thanks pal. Cheers
I thought you went on an extended bike ride with you daughter.😁 Good to have you back missed your content. Take care.
Good guess. Just went on a ride with her today. Thanks pal
Cleaned my maf at first ran a little better but codes were still there, got a new maf codes went away then came back, any suggestions?
What tests have you done? Fuel trims at idle and under load? VE test? MAF readings?
Like Mike says, "If you can get someone else to do it you're probably better off". Plus you normally get a warranty.
Now that's hysterical. Thanks pal
The parts cannon gets pricey! Nice work, Corey - great lesson! 👍👍
My computer has become super sluggish ever since I started shooting TH-cam vids, so I've been slacking on them, too. Editing and uploading takes forever. Only way to upgrade memory is through major surgery - have to pry the glass off the unit (basically pry the entire unit in half), and take every single component out of the case (of which there are many). Lots of potential for a 4-figure mistake - not sure I want to go there ... yet. I may be driven to tackle this at some point. If I had just spent another $300 for the larger screen iMac back in '15, I could have upgraded the memory in 15 seconds. Always the way! 😣
Little easier with a desktop. New build is working flawless. Thanks pal
Awesome.....
Thanks Mike
cant go wroung new level style sorted lol i ment fixed. good vid
isn't there 2 upstream 02 s ? bank 1 and 2 lean codes ? maf... i never had luck cleaning them. hey uncle bob in bringing in his car this week. he had it at the dealer for the cel and they said its nothing i guess we shall see!
Yes, 2 upstreams. I usually don't have much luck either, EXCEPT when it's from an over oiled reusuable filter. Let me know how you make out. Appreciate the help. In the words of Eric O,.....and Bobs my uncle.
With changing maf sensor and cleaning therotrl it will be ok?
"Test dont guess" is what we preach. Throwing parts at it gets expensive.
Hi my 06 rx330 idle but when you step on it it doesn’t do anything. Engine light and vsc on.. any idea?
Time for a professional to take over.
How do you tell if the bad VE results are from a MAF or something else, like an actual breathing problem?
You are absolutely correct. It's all just another tool to guide you. A vacuum leak as well could have an affect.
Would a new (advance auto budget type) MAF sensor cause this problem as well?
I have already replaced both 02 sensors as well. The guy that had it before me and his “mechanic” didn’t even research much. This is a California emissions 99 Solara. The put a denso federal emissions 02 in upstream bank 2 and a Bosch universal in bank 1. The also replaced the injectors.... with federal not California. GRRRRR!
Sounds like a host of mechanic installed defects. When it comes to sensors, solenoids and the like, I like to stick with OE.
Thank you u save me 🙏
Thank youu!!
I have a p0171 on lexus rx400h what part
Will this work on a 2003 rx300 ?
Yes sir
Another case i see with lean codes is customers put e85 gas (in non flex fuel engines) because it so cheap..
U R I’ve seen this a few times also. Toyota’s and Honda won’t even try to run on the stuff. Luckily the closest e85 station is 50 miles away so it doesn’t happen too often.
Thank goodness there's none of that around here to add to the confusion. All the best sir.
@@ThePracticalMechanic i work at a rental car company and see it quite alot.
@@SAAutoRepair lol could you imagine if the lexus had both e85 and a bad MAF
Hey can you download atg app on your phone ? and how much does it cost ?
It's free. The link is in the description of this video. I know it available for Android. Not sure about Apple. Cheers
It pays to bring it to a professional!
Thank you sir
Great tip! Thanks
grazie molto interessante
prego. Grazie per il sostegno
If you have the camera pointed on while talking the engine will be much better
👍👍
Jesus take the wheel and give it up.
Me? Why?
I found another calculator that determines how many grams per second to expect at different loads and rpm's from a MAF. Similar to the VE but a little different. Check it out: autotech.network/calculators/maf-calculator/
That's sweet. I'll find time to play with it. Thank bud
i hate. you, dont have any idea. when they dont have a clue. keep up the good vids .
great vid nothing wroungh with new level style , good show.revup tune up with air fileter good fix.and trouble shoot.
but just to take it to someone costs 80
Guessing is way more expensive. Diagnostic fee, if done right, is money well spent
You lag too much get to the point
It's not about the point, it's about the process. Shortcut, shotgun, silverbullet repairs are not my forte. But thanks for watching.
Thank you so much but you talk too much
Thanks for watching
too chatty vague did not find it helpful at all
So, you spent time to watch it, decided it wasn't useful, then spent more time to leave a negative comment, with zero punctuation, instead of just moving along. But thanks for your feedback as it bumps up my ratings.
@@SAAutoRepair Ratings is obviously the only part you care about. How about providing useful comments instead of rambling on about your diagnostics printout and providing the viewers some "how to" advice. All shops have diagnostics software, if all you have to offer is bring it in we will fix it then your content is useless. Move along? How about taking constructive criticism and providing useful content?
@@jimjones9239 dude, shut up lol.
Talk about not being able to "Taking constructive criticism"! I'm not about Silver Bullet answers. It's about the process to get the answer. Stop getting your panties in a bunch and try to learn something. As far as my ratings, they're very important, as I donate all my earnings to support young techs and get them to training. Again, thanks for stopping by
@@jimjones9239 instead of trolling a guy who's actually diagnosing and fixing cars, why don't you go invest in a camera, software, tooling, knowledge, training, etc, and let's see what you have to offer. You're a waste of time, your pathetic, and you're certainly the mouth online who would be standing in the corner in person. Go away clown. No one needs your negative garbage
