MAP Sensor Testing Using a Multimeter (Detailed Version)

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.

Very useful Thanks

[@BrendaMoore-ng1sv]

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.

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

[@user-xz9jt6jx5w]

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.

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.

[@noahschlabach2693]

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

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?

[@nadeemmohammed4770]

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.

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.

[@da64wdiy]

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.

How to identify if the map sensor is not good?

As long as you know the signal, power, and ground wire, you can check it.

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?

[@a.c.jackson6373]

I'm looking at multimeters and they have different amps. What amp multimeter should I use?

[@da64wdiy]

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.

hello sir. what is the possible reason of thick white smoke during cold start of our da64w? thanks sir more power to your channel

[@da64wdiy]

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.

[@philstrongarm]

Sir, if it still does not go away, better consult an expert mechanic for a second opinion.

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
