- This video shows how to test a MAP sensor (Manifold Absolute Pressure Sensor) using a multimeter. This method can be used on any vehicle with 3-pin connectors.
Sa video na ito, makikita kung paano mag-test ng MAP sensor (Manifold Absolute Pressure Sensor) gamit ang multimeter.
A MAP sensor measures the amount of air pressure in proportion to the vacuum inside the intake manifold. The pressure is then converted into a voltage signal, which the sensor sends to the car’s computer.
Cleaning MAP sensor:

Bro I need help from Bangladesh, my car is Nissan Sunny X Saloon 2002 model, the car starts after some places then it stops suddenly, it starts again, after giving a lot of help, it cranks and does not start, after taking a rest for a while it starts again. Turns on and off again, please tell me for which purse this happens.
There are a few possible reasons that could be causing your vehicle to stall suddenly after starting or won't start. A few may be dirty or faulty sensors, ignition system problems, battery and charging problems, fuel delivery problems, fuel injection issues, fuel pump leaks, or a lack of fuel. It is best to seek the help of professional mechanics who has dealt with this issue many times before.
This vid is thorough. Thank you. It helped me to diagnose my issue with my Seventh Gen Accord V6 3.0L! Kept getting a P0108 code even after replacing the MAP sensor. I could clear the code, then go for a test drive. Maybe after 5 or 6 miles - and then eventually down to 1 or 2 miles - The CEL would resurface and the car will stall and buck. Turns out it's the connector. It was brittle and the clip was weak... It wasn't holding the connection properly... I figure engine vibration would just eventually work it just lose enough to throw the code again. Just ordered a new connector.
Great video but I'm having a problem with a Suzuki Swift m15a engine. Getting the 5 volts main and ground but with it unplug and ignition on the signal return wire is already reading 4.9 volts and 4.5 volts plugged in. Is this normal? It remains like this also idling meaning I'm getting 4.5 volts at idle.

What bar map sensor is that?
My 3bar map sensor at idle only 0.5volt
Kalo yang pin nya ada 6 bagaimana cara nya om?
hello after following your tutorial (MAP Sensor Testing Using a Multimeter) I like you, my multimeter indicates more than 2 volts in the signal, engine idling is not bad, my vehicle is a 2007 citroen C4 1.6 HDI, THANKS.
Ano po sir meaning Ng MAP?
Hello, could more than 2 volts in the signal be a problem for my car? (I have a engine light turned on, my car have a loud sound air when I accelerate and it has less power )
Thanks

manifold absolute pressure
when speed up goin down its good or bad
in my skoda fabia going down to put the gas pedal
Where is your shop contact number
Only mechanics understand what is goin on here!
Very good explain thank you sir
Superb
Dear sir, i have suzuki liana and i want to increase fuel MPG by fooling map sensor signal ( reduce the output signal by .1 volt) so will it can improve slightly fuel MPG?
nice, thankyou for sharing
Very high quality video guide.
Very nice video thank
So my signal is at while car on at .98 sometimes .96 around there what is my fix than is this a wiring issue or my map sensor because i already have bought 2 of them. Please i need my car running again
Based on the information you've provided, it's highly likely that there's a wiring issue affecting your MAP sensor. The consistent voltage readings, despite replacing the sensor twice, point to a problem with the wiring harness or connections.
It's strongly recommended to seek help from a professional mechanic. They have the experience and tools to accurately diagnose and repair electrical issues.
Result map sensor problem/notwork?
very good explanation, thank you
Good job sir 👍
Wow, clever place for a manifold absolute pressure sensor..right in the TB where you'd expect to find something like a Mass Air Flow sensor...hmm, quite quiet indeed
😊
GOING TO THE POINT good job
Halo there, can i use this methode to others map sensor with 3 pin too? Thank you
Yes sir.
@@da64wdiy thank you sir, i will try on my car then.
After a EGR delete I regularly get a low circuit boost error (MAP). Since the sensor is OK I assume it is the higher temperature because of missing intake air cooling (EGR delete) under certain conditions in traffic jam. I was wondering to connect reference voltage with a resistor to signal to lift up the reference voltage just a little bit. Any thoughts on that here?
Well are you having problems stalling or low/high rpms? Otherwise I wouldn't touch it. Or look into your cars vacuum diagram.
@@sanddude it gets to limp mode, thats why i reached out...
Where did you connect the negative (black wire) of tester? Tnx
Hi, the black wire of the tester is connected to the metal body of the car. It can be seen at this timestamp 1:23.
Defiantly you are a Professor :) thanks sharing
Aracım k11 3 pin maf sensoru bunu bulamıyorum 4 pinli var bunu 3 pıne cevire bilirmiyim
Dva pina su map senzor a dva pina su senzor temperature usisne grane.
Sir error code p0105. Palitan ko na po ba map sensor?
Check mo muna ang mga connections o linisan mo muna. Kung hindi parin maayos, palitan mo na.
FWIW: I had a faulty MAP sensor on my Ford. I bought a new one from Auto Zone and after replacing it the vehicle ran, but ran poorly. I replaced the AZ unit with a Motorcraft unit and the car ran smoothly. Might want to strongly consider buying OEM versus aftermarket.
Do you have a ford explorer? I’m having issues with mine and diagnostic is reading P0107 which is usually a bad map sensor. Autozone sold me one but it was the wrong part. New one will be here tomorrow
Kalau map sensor kia carnival input dan outputnya dimana
How to identify if the map sensor is not good?
I just cant find wiring that connects to map sensor in my Afn engine 😢
Have you checked the wiring harness near the intake manifold or traced it back from the sensor? A service manual might help, or a mechanic could assist if it’s hard to locate!
need to play this at 2X speed.
No talking please

Hi! I've tested the crankshaft sensor almost the same way. (detached the sensor) I measured 2.5V in the sensor wire and 2.5V in the power wire too. What do you think, 2.5V power wire is ok or can it be faulty?
Sorry but I haven't tested a crankshaft sensor yet.
Sar bahut bahut dhanyvad sar itna practical multimeter per sikhane ke liye

useful video , i like it....
Galingbang 5 volts sa ecu po ba?
Opo sir.
Very useful
Thanks
Professional
Where is sounds bro?
Hi, Thanks for this video.What if the Map sensor readings at idle is 2.5 v and when you rev the engine,it goes to 3.8v is it still ok.Thanks for any response from you
The reading is a bit high but I think it's still ok. If in doubt, try replacing your map sensor.
@@da64wdiy Thanks for your quick response.
Felicidades por tu video bien explicado. Tengo una duda si el arnes estuviera mal que valor marcaria en el multimetro? te pregunto pq a mi solo me da un valor de 1 en alimentacion y 1 tambien tierrra y lo mas extraño que marca 1.08 en señal de mi senosor MAP DE CHEVY C
...¿pero cuál código tiene el auto?
Geweldig heel blij mmEE
I'm looking at multimeters and they have different amps. What amp multimeter should I use?
Most multimeters have a maximum current capability of 10 amperes. We are not reading the amperage in this video, we are just getting the voltage reading and testing the continuity of the wires. So any multimeter can do this test.
Very nice 👍
usted si enseña un super like.
Ok I’m a little confused! Are you using one multi meter or two? Cuz you show two videos displaying next to each other.
I am using only one multimeter. I just want to show how to calibrate on manual ranging and analog multimeter on the displayed video at the right side.
@@da64wdiy Appreciate it. I changed the map sensor in my mom's Honda fit and now the miss and hesitation went away but now I need to swap the VTech Solonoid for her just ordered the last. What do I read the voltage with? Omws or where do I change the settings? Sorry im new time his but want to learn
Sorry but I haven't tested a VTech solenoid yet.
Thank you sir ❤
Good job ! !
Muy difícil deferente
Very very heavy video nice sir keep it up❤️☺️
Goodjob sir
Good bro.
I have a Chevy hhr with a turbo my sensor reads .75 at 20 on the voltage meter is that to low?
.75 voltage is too low, the reading should be between 1 to 2 volts.
So it is bad I will replace it I appreciate the video and your help. Thanks
EXCELLENT video! No talking, unless needed AND showing clearly of what you did!
Excellent
Very good
is this can be use to check pajero 2.8 map sensor?
As long as you know the signal, power, and ground wire, you can check it.
MAP? or MASS AIR FLOW SENSOR (MAFS)
It is MAP (Manifold Absolute Pressure) sensor.
Hi Sir, do u disconnect the wire from ECU to sensor? I wonder how the sensor get the voltage.
Owh...sorry, the wires from ecu to sensor are connected. U just insert pins.
Yes sir, you are right.
Clear, tq for the info
Happy to help
Hi, my map sensor reads 0.80-0.90 v at idle is it faulty?
Yes sir it is faulty, the reading should be 1 to 2 volts at idle.
@@da64wdiy i replaced it and my problem doesn't solved sir! :((
@@mustafasar6540 Maybe the problem is not just the map sensor. It is better to consult a good mechanic.
@@da64wdiy yeah maybe but my engine condition is very good it might be a burnt valve
ur map is ok mate
hello sir. what is the possible reason of thick white smoke during cold start of our da64w? thanks sir more power to your channel
Hello sir, if thick white smoke is still visible even when the engine is hot, the possible cause is an internal coolant leak, it is due to a cracked cylinder head, engine block, or head gasket.
@@da64wdiy hello sir, no thick smoke when engine is hot. but I wonder this thick white smoke just occurred recently. don't have that before even in cold start.
That's normal, sir.
@@da64wdiy oh ok. thanks for the info sir, but one last question. is there anything i can do to get rid of it. kinda shy during cold start because the thick white smoke will go to other people who's passing by in our area.
Sir, if it still does not go away, better consult an expert mechanic for a second opinion.
What if sir 7 pins socket maf sensor ?
I haven't tried it yet, sir.
Thts a map sensor he's checking not a maf sensor!
Bahi tum ye maltimeter kitne ko liye ho
In English sir?
Sir you are maltimeter perches price and do you should maltimeter perches
Sir, I bought it online for Php 550
What he is doing is confusing and dangerous because exposed wires can easily touch each other
Following the video carefully will not get you confused and harm.
Lot easier way just start your car then unplug the sensor and if your car stalls it is working and if it still running its not working properly
This video shows how to test a MAP sensor using a multimeter.
The car is running without pulling the plug, the rev wave continues
