Scotty I have a 95 Nissan maxima 3.0l with the automatic transmission. I have serviced the trans fluid and filter but it seems like it's stuck in 3rd gear or something. It takes off slow but when it gets up to speed it takes off like a rocket but never changes out. My fluid level shows that its accurate. Any suggestions
Scotty Kilmer Question, I have a BMW e46 2003 and I need to change the oilpan casket, (I will do this myself) is there a easyer way to change it....because the dealer takes the engine out. Thank you, Greats from Holland (Europe)
I'm 21 I just I bought my first car 5 months ago. I didn't know a single thing so when it started acting up i would take it in but they never seem to fix the problem. So I started watching your videos. Turns out it was the MAF SENSOR. Even ford themselves missed it. After that I got tired of paying someone to fuk up my care when I can do it for free. Your video is really made it possible to fix my own car now I can't stop learning about vehicles. And everything around that thank you for your amazing knowledge and all the money your saving us.
Scotty you’re a lifesaver. My GMC through those same codes yesterday and was running poorly. Just swapped out my MAF a few minutes ago and she’s running good
Would have been curious if just cleaning tge MAF sensor would have resolved the problem as they can get grubby especially if the air filter isn't changed frequent e ough.
My pops was a master mechanic and listening to you reminds me of all the stuff he used to teach me growing up, I appreciate the good news that you have in you videos man, keep up the good work, I hate I didn't know you were from Houston I would tried to find you just so I could shake your hand, good man, we need more people like you, keep up the good work bro.
I like when you show the freeze frame and live data points. Most people seem to think that diagnosis only consists of retrieving codes. Great content, Scotty.
I had a problem with my 1998 Toyota Sprinter, it use to take long to pick up when I press the gas pedal but I realized that the manifold had a leak. From I fix it the car as been running so good. Thank you Scott.
Just cleaned my air intake filter, but truck is still loosing power after five minutes of driving. Almost couldn't get home. Hopefully the MAF sensor is my issue.
Great video Scotty!! I like when you share your trouble shooting thoughts while doing the repair. It gives us inside on how you determine the bad part. Thanks!!
THANK THE LORD YOU POSTED THIS!!! I have a 2002 GMC Yukon XL with 226,000 miles and the truck just threw up both of those codes and the truck runs perfectly fine and the fuel pump was replaced at 200k for preventative maintenance and there was no vaccum leak so I couldn't it out but now hopefully replacing the MAF will help. Thanks!!!
My 1993 auto Sentra has 360k miles. Original everything but starter (5th replacement) and radiator (2nd). Came free with the wife. I'm keeping it forever and driving it when needed.
Scotty, that deep dive into scanner codes, how to correctly process what they mean, and then how to follow through, makes this one of the best videos you've ever done. Thanks so much!
Scotty, you are the smartest mechanic I have ever seen. I watch all of your vids and have learned so much from you. Please don't ever stop posting!!!!. BSP
Exactly the last problem of my car. Changed the air senzor and the car was reborn, man It's like I am driving a different car. Thanks for the tips Scotty!
I had a problem with my diesel Jeep Wrangler in Australia. The connector for the MAF sensor had a hole where a wire would usually go on a petrol Wrangler. My Jeep only used 4 of the 5 wires and water would seep down into the plug. Everytime it rained, I would have to replace the sensor. The wrangler wouldn't start with out it. I fixed it by sealing around the plug with some elctrical silicone. Works great now.
First Last makes me cry a little bit because we used to have a 06 yukon XL with 170K miles and it was such a good truck and it sounded exactly the same 😔
I have a 2001 Audi A4 Quattro Avant 1.8T , about 75000 miles on the odometer. A had a lean condition error code for a year, on and off. Sometimes the check engine light came on , but only on the freeway! I replaced the fuel filter, cleaned the fuel injectors. It did not fix the problem. Finally I cleaned the mass air flow sensor..... And no more error code since then. :)
By far the most common issue with this engine when lean codes are present are the intake gaskets and the quickest and sure way to test them is to spray carb cleaner around them with the engine running which results in a change of idle speed if a leak is present. Usually this occurs when the engine is cold because the gaskets are plastic/rubber. I've seen this many times with both sides leaking and sets lean codes. Easy fix: replace the gaskets. MAF sensor failure on this engine are not all that common. (retired ASE Master-GM service)
Mr. Goodwrench 👍 My first full time job was at a Chevy dealership in East Hartford CT. 4 years. Car Jockey, New Car Prep, Parts Driver and parts warehouse receiver/ stocker.
Hi. Just curious in your experience, is there a good way to test an O2 sensor? other than the check engine light. It seems like the O2 sensor has the final say in the fuel trim values with problems like this and would be harder to diagnose without a specific fault code?
@@wvadam O2 sensors can be tested by a quality multi meter/DVM. There are many videos on TH-cam that can help. However, from what I've seen most techs rely on their shop scan tool to do so.
Had a ‘97 Thunderbird 4.6 V-8. At a somewhat advanced age it was running funny. The resistance wire in the MAS looked wrong. There was one replacement in the entire metro area and it was at a parts store, not at a dealer. It was about $15. Problem solved. But it seems parts get scarcer as the cars get older. Wiper linkage fell apart on another car. The only one in the metro area was at that same parts store. Whew!
A local mechanic. Was going to charge my father in law $1,000 to fix his Sierra Truck. I changed this part and the air filter and the engine light went off.
love this … i have a 2006 trailblazer ever since i bought i started having problems . bought it in 2006. then early 2007 the right wheel started leaking some type of oil front right tire. every year something went wrong . think i paid more in repairs than the purchase of the vehicle 31000
I have a 2004 3L Nissan patrol. I had a MAF go in it. And it had no power at all, went into limp mode wouldn’t rev over 2000rmp. New MAF, back to normal.
I just use MAF sensor cleaner, never replaced a MAF on any car I've ever had or maintained. I find LFT has more to do with sensors and STF has more to do with intake leaks or fuel delivery issues.
Legend,learn some thing new everyday,I don’t know how many times I have replaced the 02 sensors thinking they were fucked,only to have the same problem afterwards..it was obviously the maf sensor!thanks for sharing!
My 05 Tahoe's engine made that exact whining noise and I searched for a vacuum leak and never found one. After seeing your video I'm seeing there wasn't one.
This is where the dealer has the big advantage with all of the baseline data. They can look up the exact air mass per second the MAF sensor should be reading at idle on their computer and know if the reading is wrong right away.
Whoever has the 1994. I got you if you need parts or advice. I've owned 7 and currently own 3 of these. Great cars. Cheap to maintain and slight easy to work on. Now you got GOLD if it's an SER with the 2.0 motor. A solid gold bar, if it's a 5 speed
These videos make me happy. That's why it's important to have a scan tool with live data monitoring, not just for reading codes. It'll make consumers happy and shady dealership/mechanics angry.
I've been diagnosing my MAF (short of reading waveforms). I just tried the intake gasket test with carb cleaner that you suggest in other vid. Someone else suggested a $20 unit on ebay, but I'm not buying Chinese (buy cheap, buy twice). I'm now going to do the highway speed test you mention, then order a Denso unit online. Glad to get confirmation that 'they just wear out.' At 180k on my Corolla, it may just be time.
I have a B9 2007 Tribeca in great condition Great in the snow 188,000 miles on it had it for 11 years great condition however I see a lot of people who have gotten these wrecked and have broke on them AND mine has airbag recalls that can shoot metal scrapings??!?? Subaru never told me about this recall that happened back in 2016!!!!!! I’m pissed!!!!!
You can run a 2.2 Chevy cobalt without a mass airflow sensor, it will start hard but once it’s running it’s fine, also I know because I’ve done it, ran mine in a demo derby took all that off and did good once warmed up
Yeah... great idea Scotty, change parts with actually doing a proper diagnostic diagnosis... it could be dirt where all it needed was a good clean, it may have also been oxy sensors, wiring or anything else that the computer uses to work out the stoichiometry
Love you Scotty, keep up the great work. Would be cool to see more 1996-2000 Honda Civic repair and instructional videos, Godbless you Scotty, Michael in England X
~~~~ DID SCOTTY TRY TO USE "MASS AIR FLOW SENSOR CLEANER" ????? ~~~~~ Would've been worth a try and to do on all MAF's to use a dedicated "MAF Cleaner" by CRC or other brands or to use "Tuner Cleaner" that leaves no residue........
Some Fluid Film spray on the rubber parts that slide together will make it come apart easier the next time. Do not use silicone spray- if it gets to the oxygen sensors it can damage them.
Last video I watched Scotty was complaining about "unclipping the air filter housing" and "opening 2 screw" on a BMW ignition coil change. Funny how the tone changes
Mass airflow sensors don't wear out. They get dirty. There is a heated wire that air is directed over. The air cools the wire. So you can determine how much airflow by how much the wire has cooled. Get dirt on the wire and it insulates the wire and screws up the reading. Clean the wire and good as new. Also sometimes a bug gets stuck in the passage leading to the wire. The small hole at top of inlet. Remove bug, good to go.
Had this problem on my H3 with 5.3L in it. It would only show symptoms when it was below 0 degrees Celcius and would start but want to stall. Changed both intake gaskets and prob solved.
Two comments: 1. when I check under the hood, I clean out the leaves and branches. looking at the car in the video, I have the feeling that the person doesn't check under the hood very often. 2. I have an older Toyota than discussed in the video. When I changed from primarily highway driving to stop and go, one mile hops, the fluid went dirty after only 12,500 miles. Although it appears clean now, I will do another drain because it has been another 3 years and only about 8,000 miles. Looks can be deceiving. I change the oil every year regardless of the appearance.
Scotty, we love the channel! Question: 2003 Highlander v6 160k miles sometimes has issue of shifting into highest gear(overdrive?) in highway speeds so it will rev around 3500 rpm. Been able to quick fix it by pulling over, shutting car off, waiting 10-20 seconds, starting it up again. Alot of times doing that fixes the problem but it all seems very sporadic. What could possibly be causing this problem? Electrical failures? Transmission going out? Is it a common issue?
Interesting, on my atvs they run rich when the filter is plugged, yay carbs. On my Tesla, oh I'll never have to do this again. Don't be like me and forget the air filter! Good advice Scotty lol
When checking a mass airflow sensor a resistance check is done with voltage meter on continuity if there continuity it’s holding electricity true a magnetic field then set to ohms in measure the resistance to a more approximate analysis
My 2012 Camry had the engine replaced, cracked oil pan lost the motor, but on that motor I was getting 25mpg. On this new one I'm only getting 20! No codes but in neutral I almost feel a mini misfire comes and goes as it idles, gotta give it some gas to get it going thru 1st and 2nd gear.
Absolutely brilliant video. Your human like the rest of us. Forgot to fully tighten the big clip to the inlet manifold. Tested at idle, ok. Wife the took it out, hose blew off, turned into a tank. Did I get a bollicking 😠😡👹
I removed the sensor from the air intake. Mine was held in with two screws. Each manufacturer probably uses a different design. Some cars don't have MAFs. CRC makes a spray specifically labeled as Mass Air Flow cleaner. The sensor is sensitive enough that I would only use something specifically labeled for the MAF I sprayed the cleaner on the components let it sit for about 20-30 seconds and then repeat a few times until the sensor was clean.
A machanic once told me to test mass airflow sensor start the car and unplug the sensor if the car carries on running or sounds better then the maf is bad
Daniel Holland and if it isn’t bad, it could probably use a cleaning, along with any MAP sensor. If the wires of the MAF and the diaphragm of the MAP are dirty, neither will deliver correct info to the computer for fuel delivery. Clean them at every air filter change, which won’t hurt to do at each oil change.

Scotty Kilmer you forgot to mention how the MAF sensor deals with shift patterns. And a bad sensor can ruin a trans.
Scotty Kilmer are you sure it was 100,000 miles since it’s last oil change or did you just call the video that?

Great video! I think his explanation was very well done and I learned quite a bit watching it. Thanks Scotty!
Mass airflow sensors don't wear out. They get dirty. There is a heated wire that air is directed over. The air cools the wire. So you can determine how much airflow by how much the wire has cooled. Get dirt on the wire and it insulates the wire and screws up the reading. Clean the wire and good as new. Also sometimes a bug gets stuck in the passage leading to the wire. The small hole at top of inlet. Remove bug, good to go.
You provide a great public serve, my good man! Have a happy and healthy 2020.
My neighbor is yelling me from his celica trunk again
Hence the sound of police cars during the video?
Well let him out for goodness sake
LMAO 😂😂😂
You can diagnose the MAF sensor with the scan tool also. When the numbers don't increase when you give it gas it's bad.
Had this problem on my H3 with 5.3L in it. It would only show symptoms when it was below 0 degrees Celcius and would start but want to stall. Changed both intake gaskets and prob solved.
Scotty i just replaced mine, runs great!
I like to roll up the fat Woolford and get all schmoked up while watching the Scotty Kilmers videos.
@Kent Collins lol 🤣
Watching ya videos with coffee an a spliff nice way to start a day. Good humor with good coffee
Two comments: 1. when I check under the hood, I clean out the leaves and branches. looking at the car in the video, I have the feeling that the person doesn't check under the hood very often. 2. I have an older Toyota than discussed in the video. When I changed from primarily highway driving to stop and go, one mile hops, the fluid went dirty after only 12,500 miles. Although it appears clean now, I will do another drain because it has been another 3 years and only about 8,000 miles. Looks can be deceiving. I change the oil every year regardless of the appearance.
Keep it up 👍🏽
Air flow is very important to run engine smooth. Nice video Scotty.
Scotty’s the G.O.A.T. Good looks G 🫡
Excellent information . Keep them coming.
Scotty, we love the channel! Question: 2003 Highlander v6 160k miles sometimes has issue of shifting into highest gear(overdrive?) in highway speeds so it will rev around 3500 rpm. Been able to quick fix it by pulling over, shutting car off, waiting 10-20 seconds, starting it up again. Alot of times doing that fixes the problem but it all seems very sporadic. What could possibly be causing this problem? Electrical failures? Transmission going out? Is it a common issue?
Scotty Kilmer For President!!
Practice using arm/hand movements only for limited emphasis will make Scotty's videos better.
Interesting, on my atvs they run rich when the filter is plugged, yay carbs. On my Tesla, oh I'll never have to do this again.
Don't be like me and forget the air filter! Good advice Scotty lol
When checking a mass airflow sensor a resistance check is done with voltage meter on continuity if there continuity it’s holding electricity true a magnetic field then set to ohms in measure the resistance to a more approximate analysis
This gentleman Scotty is going to live on the Earth forever to tell the truths about cars diy maintenance.
My 02 Tahoe with the 5.3L has 276,000 and still running strong
scotty is really being aggressive with these old plastics and I don’t know how they don’t break , that’s the pro mechanic
My 2012 Camry had the engine replaced, cracked oil pan lost the motor, but on that motor I was getting 25mpg. On this new one I'm only getting 20! No codes but in neutral I almost feel a mini misfire comes and goes as it idles, gotta give it some gas to get it going thru 1st and 2nd gear.
Absolutely brilliant video. Your human like the rest of us. Forgot to fully tighten the big clip to the inlet manifold. Tested at idle, ok. Wife the took it out, hose blew off, turned into a tank. Did I get a bollicking 😠😡👹
I think Scotty should do vlogs. Who doesn't wanna see Scotty confronts Chrysler Nissan etc. engineers?
I cleaned the MAF on my 02 4Runner after 180K miles. Made a big difference. Why not try cleaning the MAF first?
How do you clean the MAF sensor?
I removed the sensor from the air intake. Mine was held in with two screws. Each manufacturer probably uses a different design. Some cars don't have MAFs.
CRC makes a spray specifically labeled as Mass Air Flow cleaner. The sensor is sensitive enough that I would only use something specifically labeled for the MAF
I sprayed the cleaner on the components let it sit for about 20-30 seconds and then repeat a few times until the sensor was clean.
A machanic once told me to test mass airflow sensor start the car and unplug the sensor if the car carries on running or sounds better then the maf is bad
Daniel Holland and if it isn’t bad, it could probably use a cleaning, along with any MAP sensor. If the wires of the MAF and the diaphragm of the MAP are dirty, neither will deliver correct info to the computer for fuel delivery. Clean them at every air filter change, which won’t hurt to do at each oil change.
