I like someone who gives the technical knowledge. You really give good explanations & saved me from having to do a lot of research.
Put a battery in your smoke detector bro
How can you live with that?
@@someoneinclass1500 idk it would drive me nuts lol
Thought it was mine. Had to look up at it. 😂
😭😭
First thought
Legend has it that he still hasn't changed the battery in his smoke detector.
Came here to say it's probably not a MAP sensor... just needs a 9V battery.
Bahahaha
man so annoying listening to that
Ping!
Came to the comments just for this comment! 😅😂😅
Love how you talk to me like I’m 2. I love that, because I have no idea what I am doing and I love learning how to fix my own vehicle. Thank you so very much for your video! Please get yourself a 9volt for your smoke detector and stay safe 😊
Thank you! very nice.
He speaks soooo slow i fell asleep
@@karlburgess3331 i feel asleep and woke up and fell asleep again but i love it
I have had my share of teachers/ instructors being in the Army when oh head gear was the old steel pot you good friend are exceptional. You made sure you researched it and put the information out in an articulate manner and left no stone unturned. We are are more knowledgeable than we were ten minutes ago. I don’t know you and I’m not blowing smoke. Well done
All my symptoms on my VW, I just replaced the part and it’s working fine. But I should have found this video earlier could have saved me some cash lol. Nice vid straight to the point and accurate. The black smoke was something I noticed a while back. Thought idle and no power it the pedal when accelerating.
Fantastic discussion! This makes so much sense. Haven't had a problem yet with mine (or any of these problems---knock on wood) but decided to do some MAF/MAP cleaning as preventive maintenance. Hunting for videos on how to do this on 2017 Kia Soul and 2018 Kia Stinger... Thank you!
Hummer H3 code is P0105 now, so I ordered a Map Sensor. I hope this fixes the rough idle/check engine light. I already changed plugs, wires, air filter PVC hose, Mass air sensor and cleaned the Throttle body. First code was P0305, now it's P0105. Trying to do the cheaper stuff before I take it to a shop. Wish me luck!!!
Great info with a clear line of communication. These are on point!
Goodman very nice!
Facts!!!!
At last - a video that explains all the angled. Thank you for posting.
I have almost all of those symptoms! Thanks! :-)
Thank you. I started my car today, went to a local destination (9 min. drive), and when I pulled into the parking lot and was on my brake, my car’s RPM was fluctuating between 1-3K. At stop signs and red lights, it was a terribly rough idle, such that I was hitting 0.2K RPM, nearly killing my engine while in traffic. I sure hope it’s the MAP Sensor that is causing all this; your video seems to be pointing to so.
CHECK YOUR HOSES going to the MAP sensor! One hole, and it will act like the MAP is going bad! If hoses are good, and you replace the MAP and idle is still 'floating', you MIGHT have a stuck open IAC (Idle air control) valve...normally as easy as a TPS switch to replace...IAC and MAP work together on idle...and from what I've seen, the 'tattle tale' for a bad MAP is backfiring, while a bad hose and stuck IAC is a steady or floating idle WITHOUT miss or backfire.
@@skeetersaurus6249 mine kinda bounces between 500-1000rpms and does have a misfire. Gonna replace the IAC either way for safety but I’m guessing it’s the MAP
'95 Camaro 3.4. 150k miles. I was struggling to figure out all the problems after replacing half the fuel and ignition system. MAP sensor fixed *all* of it.
Excellent video. Succinct yet covered a multitude of faulty MAP sensor symptoms
Very nice, thank you!
What is succinct?
Real good information here especially after just looking at another video and the guy was calling it a Mass Air Flow sensor which it is not ! After much reading on GDI engines and dirty intake valves etc .etc. I just used Lucas GDI cleaner on my 2020 Kia optima 2.5 normally aspirated engine (no turbo) . This engine is not easy to get the cleaner in without crossing over the MAP sensor Everything I have read says to stay away from a Mass Air Flow sensor and I totally get it.. Question:: Is this MAP sensor on my car as sensitive to cleaning products as a MAF. They way I got this cleaner into the manifold looks like the bulk of it is going into the 2 right cylinders. I did use half the can on the other end of the manifold at the PCV hose and that looks like the left 2 cylinders get the bulk of it there. If It was put in through the throttle body it would divide up equally but douse the MAP..
Very good. Saved in my repair playlist. Thank you! 🚗👍🚗
Very kind, thank you!
@@easyautofix 👍😃👍
Awesome THANX for your perfection and time invested in helping most! most all the pointers marked but... if I have to pump gas while cold start would that be MAP or gasoline pump
Excellent explanation my friend! I learned a lot of what I didn't know. I can't seem to find an adaptor from most OBD scanners to my 93 Buick Century
Very informative, this helped me out, thanks
You should do a video on how to replace the 9v battery in your smoke detector🤣
Had all of this happen to me on my way to work last week. Turns out that it was the pigtail connector becoming loose. If you have an older car it's a good idea to zip tie your connector and map sensor connection. Check the wiring on the pigtail first to ensure it isn't a wiring issue.
Loving the content bro, clear and understandable 💪🏽
Goodman, thank you!
Turns out I had an excessively high or low voltage that was throwing everything into whack... Appreciate your content!
How did you fix it
thank you so much for this breakdown, this is exactly what's happening to my car right now 😭
Thanks so much for the information.
Much appreciated
I have those issues with my truck. I'm in the process of Changing it out🙂
Update.
2/7/23...replaced the map sensor. Truck fired up. No issues. Thanks again
Huh, my 2008 Dodge Grand Caravan literally has 7 out of these 8 symptoms; just no black smoke. I think I'm gunna go see if my MAP sensor has gone bad. Thank you. 😊
YUP! THAT THE PROBLEM IM HAVING.."LOSS OF POWER 🔋 " WHEN TRYN RACE OR HALL ASS 😢THANKS BRO,YOUR THA MAN 😎 HERES A 9V BATTERY 🔋 FOR YOUR SMOKE DETECTOR 😎
Thank you very much for fantastic video. I had some of The symptoms. After cleaning The map sensor 4 times and clean The hull on The intake manifold. My Bmw 525D works fine snd The turbo is working top. No more lag, no more drive train errors
Thank to you guys sharing yout knowledge on RUclips has made my days easier. I have learned a lot and manage to repair my car. Thank you again and keep on sharing.😊
Awesome, thank you!
Cheers for the video! The fire alarm beep gave me a laugh haha
Muchas gracias mi pana, justamente la falla que tiene mi carro.
Excellent job sir 👏🏽
Wholesome. Subscribed.
Great videos!! My 2002 dodge ram 1500 4.7 engine. I get a little smoke at fast acceleration and it sounds like at idle the throttle body sucking in too much air cuz it whistles a little bit.
Just had to change out the sensor on my 2010 kia forte. It was 118 miles away from 125k. It runs so much nicer now, too.
All are actually great indicators. But the last one. Fuel comes out of your exaughst every time you drive. If you have black smoke it is most likely a manifold gasket leak. And needs to be taken to a shop right away before you cause permanent damage.
Great video. Thanks
I like how you broke it down!!!!
subscribed, great content
Right On Brother, Thanks you've brought a lot to LIGHT!!!
Well explained
We have a rough idle, sometimes dies. You reatart, it'll run. We're getting minor white smoke. But no other symptoms of valve cover head gasket issues. No milky oil, no smell of coolant, but are getting bubbling in the coolant reservoir (which we just replaced.
Valve cover gasket was replaced earlier this year.
Mechanic cleaned off our map sensor. Ran finw for two days, now doing it again.
Thank you!
thank u for these useful informations >>
I have a p007b for my f150 2.7l would this be the right part to replace?
Great video. Is this anyway related to Vaccum sensors? I get this glow plug error and no one is able to fix. Someone finally said the vaccum sensor is faulty and that's causing this error. Pls advice
Thanks for info!!!
Very nice!
Thanks very much
Thank you for your time to comment!
Thanks for the help my friend!!
Thank you!
4.7 liter Jeep. Have 1800miles on a new engine. I got P0108 code and cleared it. MAP sensors apparently do fail. My symptoms are clouds of smoke. I tried running some 89 octane and that compounded the issue. Smokes even worse. I’m certain the engine is fine so this is the next part swap.
Thank you for the great videos
One question is the code P2191 related to the bad MAP or bad injectors !?
Hello I don’t know if you’ll reply, but when I was cleaning the MAP sensor I actually broke the part that goes is with the gasket, but managed to put it back and there are no codes, it’s been like 2 months, so I don’t know if I should replace it.
Awesome explanation
Awesome comment!
Wow awsome video man! Thanks!! Helped❤
Awesome thank you!
Would this sensor cause issues where it stumbles until you give the beans? It's a 05 Dodge with a 4.7
I'm not a mechanic, but can confirm your question. I have a colleague with an 06 ram 4.7L and the same issue.
Very good explaining.Make you a deal you come and change mine out and I’ll come by and replace the batteries in your smoke alarm.Thanks for the video though I seen a few you put out already 👍.thank you
My daughter has a 2015 Chevy Cruze. Recently the check engine light come on and it seems like the throttle response is lagging when you excelerate. It has power, but it’s just on take off. Took it to my local orielly and their scan showed not getting enough fuel and the MAP code. What do you think? TIA
thank you!!!
and thank you!
Hello new friend here...thanks for sharing...
Fantastic, I really appreciate your help ❤❤❤❤
Happy to help!
Are we not gonna mention the dying fire alarm? 😂
Amizing info!! It really helps understand how it all works But if the map sensor is intermittently throwing the wrong voltages and im assuming these voltages are important to the milli volts then how does a DIY tech tests that it's gone bad 😳 unless you have some type of jig that can give it pressure and you can measure precisely the data voltage and be able to compare it to a diagram for hours I don't see how we are able to ever really say... this map sensor is in great condition.
So I have kinda weird question? I have a 2011 Kia soul 1.6L base model, my check engine light comes on not all the time when I get to half and sometimes a quarter tank of gas. Then when I fill up it goes back off when I park and then start it back up the next day. It has been like that for some time, do you have any idea what it could be? I was thinking map sensor. Like I described the check engine light doesn't always come on. Sometimes it won't even come on at all for several weeks or months, I'm baffled. I did replace the gas cap, Any help would be fantastic!!! Love your channel and content
I have a 2004 Trailblazer with a 4.2 liter inline 6. I was getting 14.3 mpg mix driving. The truck ran fine and didn’t have a cel. Now I’m getting 16.5 mpg. I have a few video about my truck.
Hi, I could relate to 4 and 7 the power kicks in after 2500/3000rpm till then its very sluggish. Fuel economy is bad. could MAP be the reason. don't have the check light or fault code.
Ford ranger 2.3 07 drives perfect and losses 100% power for a few seconds and goes back to normal. Would this be MAP sensor related?
Thanks for the information, this video is very helpful.What is the name of the music that is in the background? it's cool.
thank you so much
My 17 Impala sounds like it's misfires when first starting nd then idles down n rides ok. But gets 5 mph less than it was, the auto store indicated also there was low voltage to the maps so need to check it out.
Putting one on today on my 5.7 Hemi. Mine acts like it's running out of gas, yet no check engine light at all so far. I'm hoping this is the answer but got my hopes down lol.
Good info but what's with the chirping?
I have a 1998 Mitsubishi eclipse with a 2.0l engine (420A). Can a bad EGR cause the engine to burn oil at low rpms? I put new rings, bearings, timing belt, water pump and had the head rebuilt, basically rebuilt the engine. When I first start it up it runs and drives fine but after the engine warms up it lets out a big plume of smoke when I take off from a light or slow down and speed back up. I can't figure out what is causing it to smoke so heavily, it smoke's so heavy that I can't see the car behind me but after a few seconds of driving down the road it clears up and does not smoke until I stop or slow back down and speed up. I have also relaced the fuel pressure regulator, Idle air valve, both temp sending units, and the catalytic converter but it is still burning oil after it warms up, when it is cold it does not burn oil. What can be causing this problem?
My Hyundai accent is experiencing a good amount of these symptoms. I recently took it and cleaned it kinda helped but I am still experiencing some of these issues. Car does have 150k miles on it already so I assume it needs to be replaced
Nice video 👍. I have a issue with cold start. Its start but after few seconds the engine is vibrating and a bad idle. After 5 min the engine runs fine again. Could it be Map sensor on my car to?
Change your smoke detector battery, THEN make this video so the beep doesn’t happen in the background
does it also backfire since there's fuel in the exhaust?
Started getting a backfire...but at first, it was rare...but every once in a while it would also 'drop idle' to low...so I think, 'hmmm....TPS sensor'. I replace it...but no change. Idle gets worse, so I think 'IAC valve'...clean everything up and replace it...OMG, my RPM now idles at 3,000! I keep looking, then see it...looks like dirt on a hose. NOPE...ROTTED HOSE on my MAP sensor! Go to replace it...and ANOTHER HOSE connected to it literally FALLS APART in my hands (goes to the PVC valve)! Nice...end up having to replace EVERY SINGLE HOSE going to my MAP Sensor! Get that done...and I can take the new MAP sensor back to the parts house...IT WAS ALL THE DAMN VACUUM LEAKS GOING TO THE MAP SENSOR!
Thanks much
Hi sir
Map sensor & maf are same funtion?
And both fiex all cars, or any one only. My lancer glx 2011 have smoke, rough idle, lossing power, not good pickup, it means map sensor or maf bad,?
Breaking up during heavy acceleration, can also lead too the map sensor going out. Found that out today after 2 years and alot of change out parts too understand why I couldn't get pass 5,400RPM at heavy acceleration..
When parking my car for long period while engine is on, the engine stalls for no reason. When the car runs, the problem dissappears.
Do you think is os because of MAP sensor?
Thanks!
Very nice of you! thank you for your donation
Could the bad map sensor cause your rpm to read 0 when you don’t press the gas pedal? I have a 93 f350
Not the smoke alarm batteries dying 🤣🤣
dont necessarily need to replace it. The engine light can come on from a dirty MAP sensor. Use MAP sensor cleaner (and ONLY MAP sensor cleaner), take the sensor out, and give it a good spray all over. Don't spray the part it plugs into, just the removable sensor itself. Let it dry _completely._ And that could be all you need.
Have a Cadillac ATS have the same symptoms I check for vacuum leak nothing I don’t here the fuel pump but make whining sound at high speed
My car out of sudden it shut off on me on a stop sign then the next day when I go to work it was okay but it started to shake at when car was stopped. Thee real problem was when I got off at work I went to get the freeway but it stopped at 20 mph wouldn’t go higher the engine made a weird noise. I had to let go of accelerator and press it again to go higher When I press the accelerator it start to shake and it does go higher than speed and it worked. It kinda shakes too when the I press the accelerator I also told notice the needle in the rpm goes up and down. Can this be a issue ? I haven’t gone to get it check with the check engine machine
Definitely has the symptoms. The next step would be to get that check engine light checked out to read the codes and go from there.
This just happened to me. I took it to the shop and they said they replaced the map but the engine light is still on and I still can’t go over 50 mph. Should I ask them to replace the hoses or could it be something else?
Hello
I have a vw passat cc 2.0 tdi 2009 I get these two codes p0238 p0113.the problem is I changed the sensor back to the same codes I took out on the computer.
Thanks for help
I’m getting P1105 code, would that be a map sensor also to be replaced ?
Hi mate.. on an automatic would a bad map sensor cause over an over rev?
Makes you wish for the old carby engines...all this electronic bs and expensive parts for at best nominal mileage improvements
These sensors are like $20… what you mean lol
I’m so tired of hearing these types of comments, carbs suck, they can’t adjust for altitude or hotter or colder days. They give little to zero feed back.
Oh no did I hit a speed bump two hard, damn now my float bowl is stuck flooding my engine that won’t let me go home.
Is it too hot outside? Vapor lock in my fuel line won’t let me go home.
Too cold outside? My fuel won’t vaporize I can’t leave my house
My carb engine has this sensor sooo
Ok boomer
@@cobbfutbol62 02 sensor for 2015 Rav4: $253.00
With the amount of times I heard that alarm going off, it’s safe to say it was intentional 😂
Other than buying a new one what a the best way to rectify a bad MAP.
Bro they only cost like $30

Since you helped me diagnose my car I'll help you diagnose your smoke detector: it's chirping because it needs a new battery. All kidding aside thanks for the good video that helped me a lot!
My car cold starts at 800 rpms when the weather is cold (like below 16 degrees Celsius) can it be because of the map. Replaced injectors, coils, plugs, maf and cleaned the throttle body
mine is a p1297 for my 02 dodge ram 1500. and i got this code at 158k miles. i brought up the code by turning the key forward and back 3 times! It says theres about 4 reasons why it could be faulty but i bet its the map sensor.! ill let yall know. ive changed air control valve o2 sensors and purge valve no luck but im buying a map censor today
Awesome goodluck!
Did it work?
@@gmarinelarena8675 No 100% but mine was very black and dirty. i bet i have a short somewhere because when i turn the ac on it idles way lower. i feel tho changing the map sensor helped it from stalling out. It helped enough to get me around!
@@fadedacorn if you have a multimeter you can check the batery voltage. It might be the alternator if the problem happens when you turn on the ac.
My truck has a v8 map sensor and I recently found out that’s the problem. I’m guessing a v8 sucks in a different amount of air causing it to be like that.
Good presentation. Last question: what causes that 'beep' sound in the back ground? ;)
Dead/dying battery in a smoke detector.
