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! 😅😂😅
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
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
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!
At last - a video that explains all the angled. Thank you for posting.
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!!!
'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.
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
thank you so much for this breakdown, this is exactly what's happening to my car right now 😭
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
I have almost all of those symptoms! Thanks! :-)
Great info with a clear line of communication. These are on point!
Goodman very nice!
Facts!!!!
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. 😊
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.
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..
Excellent video. Succinct yet covered a multitude of faulty MAP sensor symptoms
Very nice, thank you!
What is succinct?
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
Muchas gracias mi pana, justamente la falla que tiene mi carro.
Very good. Saved in my repair playlist. Thank you! 🚗👍🚗
Very kind, thank you!
@@easyautofix 👍😃👍
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 CZcams 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!
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.
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
Very informative, this helped me out, thanks
Loving the content bro, clear and understandable 💪🏽
Goodman, thank you!
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
I have a p007b for my f150 2.7l would this be the right part to replace?
Turns out I had an excessively high or low voltage that was throwing everything into whack... Appreciate your content!
How did you fix it
Cheers for the video! The fire alarm beep gave me a laugh haha
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.
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
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.
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.
Right On Brother, Thanks you've brought a lot to LIGHT!!!
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?
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.
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
I like how you broke it down!!!!
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.
Excellent job sir 👏🏽
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
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?
Thank you for the great videos
One question is the code P2191 related to the bad MAP or bad injectors !?
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.
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
Could the bad map sensor cause your rpm to read 0 when you don’t press the gas pedal? I have a 93 f350
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?
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?
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 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
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.
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?
Great video. Thanks
You should do a video on how to replace the 9v battery in your smoke detector🤣
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
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.
Wholesome. Subscribed.
does it also backfire since there's fuel in the exhaust?
Okay I need help so I have a Acura Integra automatic and yeah it picks up up to 50 or 60 then I’m flooring it still and it goes up but it takes its time to get up their once I’m up past 60 I can probably push the whole peddle down and it probably won’t respond with the power I want
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,?
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 u for these useful informations >>
Well explained
hi i have no engine light but lack of power in the begining when i accelereate no boost and fuel consomption could this be the MAP ?
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

i have dual exhaust .. can i get black smoke from one bank and the other be clean due to the MAP sensor .. my 3.6 V6 runs sooty rich on bank 2 and clean on bank one ,, driving me crazy ..
I’m getting P1105 code, would that be a map sensor also to be replaced ?
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.
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.
My car have a code p2004 any help . I ready change imrc solenoid and of connector but still shows of code
Hi mate.. on an automatic would a bad map sensor cause over an over rev?
Thank you!
Hi i have code p0171 and i tried removing the clip from MAF and truck did in fact turn off. So my MAF sensor is fine? What else could it be???
Hola!
☝️Una pregunta técnica.
Yo tengo un Corolla año 2001 en Venezuela 🇻🇪 tipo 1.6; es decir 4AFE y no está llegando corriente ni señal al sensor de oxigeno. Esto me esta causando que el motor consuma mucho combustible⛽️ y ademas presenta olor a gosolina con humo blanco 💨 y negro por el sistema de escape. Usa un cable de 12 volt + señal + (02) cables para un calentador o bobina pero ninguno tienen voltaje desde la salida de la ECU.
CUAL ES TU RECOMENDACIÓN?
Espero tus comentarios.
Gracias

how often does a MAP Sensor go bad. i changed mine about 3 months ago and my car is just now showing reduced engine power. i got a check engine reading. and it said the MAP sensor is bad again.
Wow awsome video man! Thanks!! Helped❤
Awesome thank you!
Hello new friend here...thanks for sharing...
I have MAP sensor code and EGR code.... No smell of gas... seems like it lacks power but the 06 freestyle is a dog with the CVR trans, City fuel economy is pathetic, 13 mpg. Highway around 25.5 which is ok. No smoke. What would you do? I cleaned that sensor multiple times.
subscribed, great content
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..
Can it cause lean codes. Need to know thanks
I have a 2014 honda civic and in the winter below 30F, even when fully warmed up moderatley accelerating a little over 2K rpm i get like a shaking shimmer. warms up above 30F and it goes away. anyone any ideas.
My ce light came on and read code p106
The rpms went up and down when the car was stopped. Kind of hesitates. Was going to take it to the mechanic when they opened. The check engine turned off on its own? Never had that happen :/
Thanks for the help my friend!!
Thank you!
I have a map sensor harnes reading 6.2 volts on the signal wire (engine off). The 5 volt reference is correct (5v) and my ground is also ok.
Would cleaning dirty MAP sensor with MAF cleaner give results?
Would it harm the sensor?
I have black smoke need help with this I upgraded my mods!
Fantastic, I really appreciate your help ❤❤❤❤
Happy to help!
Will this trigger P0171 ?
I’m running P2015 on my 2009 Audi a4 2.0T base
2011 1500 dodge ram 4.7 classic flex fuel sometimes it take a while to pick up n it doesn't let me burn tires no codes but the map sensor is brown inside it think it might it
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.
thank you so much
Awesome explanation
Awesome comment!
Can you change the 9v battery in your smoke detector... thank you
Motor shaking vibrating reason this sensor possible?
Thanks for info!!!
Very nice!
