Thank you very much for sharing, sequence you need to change. At first Voltage to check in all 3 terminals. Identify the HOT wire. Then jump to Continuity , and do not check the continuity on HOT wire (Multi meter or the sensor will damage). Once you identify the ground wire , the remaining wire is sensor. And second one While testing the voltage on the sensor , a. increase the rpm slowly to the max, ( voltage must go all the way high without disconnecting) , same in reverse. ( this shows that there is no dead spot on the resistance)
Hallo from Malaysian.. u are the person what men need in TH-cam!!! Good job thanks for helping me.. my wire out from socket and you are really helping!!!!!.
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.
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.
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
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
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.
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?
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.
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?
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.
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
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
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!
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
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.
@@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
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?
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.
@@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.

Well are you having problems stalling or low/high rpms? Otherwise I wouldn't touch it. Or look into your cars vacuum diagram.

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

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!
Its inside the ECU mate internally
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.

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.

Hi Sir, do u disconnect the wire from ECU to sensor? I wonder how the sensor get the voltage.

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
