Map Sensor P0107 and P0108 | How to Test and Replace
ฝัง

- A map sensor measures barometric pressure. This pressure is then converted into an electrical signal for the ECM. Unfortunately, you'll need a very sophisticated scan tool to measure the barometric pressure via kilopascals (kpa). However, you can test the sensor via the amount of volts at idle. We show you how to do so.
Specs for this vehicle:
Volts at idle: 1.4 - 1.8v (or 20-47kpa)
P0107: Volts under or equal to .6v (or 13kpa)
P0108: Volts at or above 4.4v (or 120kpa)

#mapsensor #p0107 #p0108 - ยานยนต์และพาหนะ
YOU'RE AWESOME! Can't even count how many videos I've watched, 3 service manuals, and unlimited shade tree idiots advice. Your video explains PERFECTLY how to test the sensor and wiring! Found my problem! THANK YOU!!!
So quick and so easy, you explained it so that everyone would understand.
Thank you
This is so far the best and most instructive video on MAP sensors I have seen, short and concise You got a new Prenum, and no irritating music or weird sounding in the background
Thank you. I appreciate the feedback.
Hats off to your amazing style and thorough explanation that are much needed given most of us are DIYs! THANK YOU!
I just bought a meter like that, and that is the first thing I will test tomorrow ( The MAPsensor) . I needed this video.
Awesomely detailed explanation and great suggestions!!
Thanks for the informative help!!
Good video, you explained things well and did a good job putting what you were doing into frame.
Sister's Outback was stalling when you'd give it gas from a standing start or if you revved it up it would stall when it dropped to idle.
ODBII showed a P0108.
After watching this vid I had my meter and 2 paper clips in hand, pop the hood, look at the MAP sensor, it is unplugged.
Plugged it in, ran like a champ.
I'd done plugs, wires and valve cover gasket on her car the day before and must have missed plugging that back in.
we need more mechanics like you who know how to explain things clearly
Thank you.
This is NOT the MAP, guys. It's the MAF.
DITTO THAT BOSS
@@thegadgetmangroove6304 YOU SURE, MANIFOLD ABSOLUTE PRESSURE SITS ATOP MANIFOLD , MAS AIR FLOW SENSOR SITS AFTER AIRBOX AND BEFORE THROTTLE BODY
EXCELLENT clip.
Especially for me who absolutely is shitty in this subject, but currently strugling with my old Slk Mercedes and have p0107 code.
Tomorrow gonna make same tests.
Thank you for that 👏👍
That's brilliant mate; thank you from an old School Panel beater. Well, well explained cheers:)
Great, very informative video. Thanks!
Thanks for the information,it was very easy to eliminate the map sensor from my process of elimination with a stubborn Saab.
Was it a 92x??
God bless you! You were clear and understandable. You rock!
thanks for the detailed description! very informative
This is NOT the MAP, guys. It's the MAF.
@@thegadgetmangroove6304 You're wrong. he showed where the MAF is, it comes off the air cleaner. This is the MAP sensor.
Big thanks for the insights and easy to understand detail tutorials.
God bless you. Thanks for the video buddy!
I wish I had teachers like you, you are the best, great video
Thank you. Appreciate the feedback.
one of the best dam vids on engine problems, sound intelligent -extremely, and great explanations, still looking for MAP SENSOR LOCATION 2001 BLAZER 4.3, KEEP MAKING THESE TO THE POINT HIGH IQ VIDS
Thank you. Happy to help. If you can't find a schematic online try a Hanes/Chilton manual.
I had a clogged map sensor on my 98 chevy. It was causing hard start issues when vehicle was warm. Replacing the sensor resolved problem. Pulling out sensor and visibly inspecting is recommended as well
Richard Rice how’d u know if it’s clog
probably can tell when cleaning if clogged+ i think i may have same issue +hard starting when engine is fully warmed.
Great video. Good information and very good at explaining. Thank you.
This really helped me solving my problem with this sensor :) Thanks a lot!
Glad to help!

thank you braada, well explained
Happy to help.
If you don't check sensor with Vacuum pump and meter you're not going to know if it is truly functioning properly :) The sensor costs a whopping $9.00 on Amazon :) Took me 10 minutes to order it and 1 minute to install it and boom! Problem solved :) I guess I'm more into fixing than I am testing :) Great video instructional on that old scanner :)
excelente gracias
Thank you sir...very informative
Thanks so much. You have helped me a lot
good job , thanks a lot .
Thnxs bro VERY GOOD tutorial
Nice video!
Thanks excellent video & perfect explanation, take care blessings
Thank you your explanation very helpful

Great video
You're awesome great video thank you
You are so welcome
This guy right there and that guy
Really helpful thanks for putting the video up
Awesome. Glad to help.
This is a great video. I'm sure it would have worked for me if my engine would idle for 1 minute.
Mine dies too. Did you figure out what the problem was? I'm ready to just replace the MAP sensor and cross my fingers.
you are a living legend sir! you were super clear and imformative, where as everyone else were just telling me what to do but not explaining why.... i have p0108, i replaced the map but still have the code, should i start looking for vacuum leaks?
Did you figure it out?
Great explanation simple and straight forward. Comment, I own a 2007 Ford Sport Trac 4.0 unfortunately the MAP sensor is almost impossible to identify and all google searches aren't much help. I believe I found the culprit sensor, however it has 4 input wires and very difficult to extract. Question once it is found and repaired how do you reset and remove the dash fault without a code reader?? Duane S
Thank you very much use full video
Thank you so much for this detailed demo. Question: my 2008 mazda 3i 2.0L idles rough sometimes I gear but never when in P or N. The RPMs drop low as if to so out & die, though it never does. It's been suggested that perhaps the MAP sensor needs to be replaced. Is it possible that a MAP sensor not work and not show a DTC? I've never received a P107 or P108 and currently have no codes. Is it safe to assume it's not the MAP sensor?
Any & all feedback would be greatly appreciated.
Thank you again - liked!
I am getting 3.1 to 3.2 volts on p0108. I have the same engine as you, any insights?
Very helpful. Thank you
Thanks
Welcome
Good videos
Excellent video thank you I think my map sensor has failed getting same code on the scanner
Perfect 👍👍👍👍👍👍👍👍
@CarsandToys i have a 1999 Nissan Maxima with a code that says P1105 from OBD 2 test at an Autozone . Revommended fix says replace MAP Sensor, but the P1105 code led me to your P1105 video on the same car i have but says its to replace MAP Baro Switch solenoid valve. So which one is it more likely tht needs change between the Map baro switch and the MAP sensor. Also confused on wording. Is the MAP sensor the same as the Absolute Pressure sensor near throttle body of Nissan Maxima 1999?? Should i just trust the obd 2 test n replace the Map sensor aka absolute pressure sensor n hope tht turns annoying chk engine light code off???
So smart 👊
Great video, the messed up part for me is that my map censor is intergraded to the EGR so it's expensive 🤦🏻👍
I checked my old sensor doing an ohm test and it reads 4.8kilo ohms which is an ACdelco sensor. Then I bought a new one that's a duralast brand but it reads 1.88kilo ohms. My wiring harness seems fine but I'm not sure if either of these sensors is working properly. Should I exchange the new sensor for a different brand to see if it reads 2.5k ohms??
Hi! I have a 2007 2.5L subaru outback (same engine) and my car won't start, scan indicates error P0108. I followed your guide and all checks out however the car refused to start, is there another test to do or process to follow?
I got a P0107 code two weeks ago. Car runs great, perhaps better than ever. Mileage is up! So how likely is it that my Map Sensor is bad?
thanks
What if my ohms test was 1.6 it is a good map sensor? Thanks
Great information vidio! My 2008 gmc sierra was giving me a p0107 code. I put a new map sensor on it. It didn't help. I back probed the map sensor plug and the reading fluctuated dramatically. Turned out to be a bad place in the wiring. Fixed the wiring and truck runs great now . Hope this helps someone.
I like it.
Thank you.
My Mercedes w203 Sensor map is located next to the maf sensor is with 3.44v is the other atmospheric pressure map sensor of the intake manifold is 1.98v. Some ideals?
In the back comes a white smoke with a strange smell?
Wow, that was great. Very good explanation and tutorial! Thanks!
I have a question that no one else can seem to answer
Whenever I go above 7000 feet in my 98 Jeep Wrangler and do engine braking it triggers a PO107 map sensor code
Otherwise I have no other issues that would be attributed to the map sensor it runs great
Once I get back to town the light turns off and no issues Except now it’s a confirmed code and I’m having to deal with getting it Smogged
Any ideas/suggestions?
should the continuity test be done with key off or on acc?
So I had to move a lot of stuff around on my car when I was replacing the oil filter adapter gasket, in order to stop an oil leak on a 2007 3.5L V6 Chevy Malibu, and when I put everything back together I got this P0107 code come up. I've tried the voltage test on the wiring to the MAP sensor, but my wire colors are off and I'm not getting the 5V reading that you're getting. I have the multi-meter set on 20V DC and I'm only getting a reading of .05 Volts on the grey wire (The grey wire is located in the same place as your red wire, but it's grey). The red wire and the green wire has no voltage. And when I check continuity (the 200 ohm reading with the wifi symbol), the multi-meter beeps continuity on the red wire and the red wire is located all the way on the other end away from the grey wire (it's not in the middle). Is it possible, I have a break in the wire or is there a connector that might be damaged? I had trouble putting some connectors back on when I was putting the oil filter adapter back together. Mainly the ignition switch wire on the starter (I moved this to get to some of the bolts on the oil filter adapter) and I had issues getting this sensor wire back into the oil filter adapter. I don't think either of those connectors would have much to do with the MAP sensor. Also, I took off the air intake hose and only removed one connection on the front of the engine, but I don't think I damaged anything putting that stuff back together. I may try some other tests to see if it could be something else and I may track down that wire assembly to see if there are any issues with that. If anybody has any other helpful advice that would be awesome. (Edit: I think I found out what has caused the issue because some other codes cam up suggesting that there is a short in the circuit which is causing low power and some other issues. I think I damaged the plug for my oil pressure sensor and this caused a short. I'm going to replace this plug and see if this fixes the problem.)
Very Interesting ! Just curious if the oil sensor was the cause of your map code ? I have the same code and replaced the sensor. It ran ok for about 300 miles and now it's back, along with others, one being (PO641 for voltage). I'm gonna change the oil anyway so I'll check the sensor. My gas gauge is also erratic when the map code is on. Would appreciate Any feedback. Thanks...Cf

Please help!!!! I have a 2004 Jeep Grand Cherokee Laredo when I first turn it on (cold start) and drive it down the street it stalls really bad like it wants to turn off but after about 3 minutes or so when the engine is warmed up it goes back to normal and runs good again I changed the crank sensor, camshaft sensor, idle control valve, and throttle position sensor I’m getting the cods p0123 p0505 and p0108 please help
Sir, why one output terminal of my car ignition coil gives less sparks than the other terminal. In fact, the 2 terminals are control by a single primary circuit of the same ignition coil!!! The other ignition coil has the same issue.
I have checked for all resistance readings of the PRIMARY AND SECONDARY CIRCUITS of each IGNITION COILS which shows normal values.
Please kindly help.
Thanks.
Nice Video; I got a question bro, when you checked for the 5V on the red wire right, could you also have inputted the black lead on your voltmeter device in the middle port slot on your connector to use it as ground in that process ?. Rather than what you did. Also im trying to measure the voltage for a connector going to a sensor in my car right; my question is this; The book im using as a repair guide for my car is telling me to measure the voltage between terminals number 1 and 2, then between terminal 2 and 3,
1-->> Power side
2-->> Sensor Ground
3-->> Signal
So from wacthing your insightful video, correct me if im wrong right, but the (2) wire is mentioned twice because when testing for volt, you need a ground side right ?
Also another question, can you get 5V from the other two wires in the video ?
Please respond asap TYVM !! :)
I used 20v DC setting on my meter. Put the black tester on the negative connection of the car battery. Tested my meter by putting the red tester on positive battery connection to get 12.5v reading. Then left the black tester connected to the negative car battery connection and used the red tester on the power cable to the sensor. The right hand connection out of the 3 gave me 5.5v reading. Not going to bother with the other tests as I cant get access to the backfeed of the wires. Going to get a new MAP / boost senor today to replace.
I have this error with misfiring and black soot only on cylinder two. Wouldn't a faulty map sensor cause misfire on more than one cylinder?
2013 chevy equinox 2.4l.. i changed my Map sensor and checked the wires and d voltage are good but the check engine light comes back on with the same Code.. please help
Wouythis code throw after upgrading turbo and seeing more boost?

I'm getting P1296 after I replaced the IAC & TPS. Cleaned the throttle body, changed the spark plugs and replaced a broken vacuum boot. Stalls at low speed, stops and deceleration. If I replace the MAP and still stalls, what's next??
Very friendly guy
I tested at 2.7 volts on my fuel rail pressure sensor. Is this also bad...
If you increase the rpm you should see a change in the reading
Replacing the map sensor is just plug and play? New map sensors don't need some sort of calibration? Thx.
All map sensors are is variable resistors
If the vehicle can't start, or is struggling, how do you test the map sensor?
Ohm tester like what he has!
i replaced mine and it fixed the issue. Is there some way to check ohms--with it off the vehicle to confirm it was toasted?
On some vehicles you certainly can. On others it isn't so easy.
I'm getting code p0108. 2004 WRX 2.0, where did you buy your replacement sensor from?
Ohms test my map sensor for wrx 2006 its not reading 15 Ohms getting 2.3 it went up to 15 ohm two times and then back to 2.3 . please help car is reving over 3000 rpm at idle
The mass airflow sensor doesn't respond quick enough to throttle response so they had to put a vacuum pressure nowadays they use a pot. control drive-by-wire a pot a potentiometer so you can't slam the gas pedal down
This sensor is before the throttle body. Looks more like a MAF sensor. The MAP sensor sits behind the throttle body.
Do that make the knocking sound
cool
In 3:34 your multimeter emitted sound, but mine doesn't have that option. What kind procedure do I have to do to figure out the ground wire ?
Touch the red and black wire together it should say 1 indicating continuity. That is what you should see. Many meters are inexpensive and do not give an audible function. Look for that numeral for a good connection.
Can a test light test it too? Help
What if you don’t see a reading of the map sensor I’m getting 0.00 with ignition on and off
I got 5V on signal cable when the sensor is or not connected what does it mean? I got 5k Ohms
GREAT VIDEO. BUT PLEASE MENTION IN YOUR VIDEOS THAT NOT ALL SENSORS CAN BE TESTED USING RESISTENCE TESTING. HAL EFFECT SENSORS WITH GET DAMAGED
so 1106 code on a Pontiac g6 map works great but dies at a full tank of gas replaced canister and what not now I'm screaming inside...
(2:00) would you see any voltage at the signal wire at this point? I have P0108 code and I see one wire at 5V and other at 4.8V and 3rd is ground. is it normal?
What kind of vehicle are you working on?
Corsa D 2007 (z14xep).
Error is intermittent which makes me think it might be the sensor going bad, or a faulty wiring ?? at the error (on idle) , STFT goes way up 25% and oxygen sensor reads very low 0.1v and MAP reading goes high to atm pressure. (p0108 and p0300)
@@victorsaari1393 well according to your stft its compensating. Your map sensor most likely sending false voltages, unplug it if your car has a maf and see if it runs better
yes, replaced the map sensor, and it runs way better now, and increased gas mileage as well. I guess it had been putting in extra fuel to compensate for faulty map reading.
Thank you
Where is the map sensor on a 1999 Mazda protege? It’s not even listed in the manual
What about code P0106?
I think I damaged my MAP sensor cleaning it. It was fine, but I cleaned it along with the throttle body because the car has over 150k miles and it had never been cleaned. It only starts and stalls immediately now, where it ran perfect before. I stuck the red plastic tube from the cleaner can in the hole of the sensor to clean it out. I looked in there with a flashlight and it looks to be pushed in in the center where I poked the red tube in. I'm getting code PO108 circuit high input. I took it out and tried cleaning it again, but still shuts down after it starts. Actually, when I cleaned it the first time and put it back in, it stalled the first time I started it, but after starting it again, I drove it a couple of miles and it drove perfectly. I went out an hr later and she stalls every time I start her now and the check engine light is on. I know you're not supposed to touch the small wires on a MAF sensor as they're delicate, but a MAP sensor is probably just as delicate inside (?) It was enclosed so I though it best to push the tube in and clean the gunk out, but I fear I've ruined it. If I did, It's not a high dollar one, but I've learned a lesson. Does that kind of damage sound possible from what I've told you? Thanks, and keep the great videos coming.
They very delicate these sensors; especially on certain vehicles like this Subaru. If all the prongs look healthy you may have to replace it. The flip side is purchase a new sensor and see if it corrects the problem.
Mazda's need 1 pint of Sea Foam in oil. Engine will then go from sounding like a bucket of bolts to smooth and quiet.
I can’t find it on my 05 Chrysler 300 3.5 v6 engine
Mine is n16 nissan it has 4 wires in maf sensor.

I have a P0108 code but I tried replacing two different sensors and still no solution. My car shakes when idle and struggles to turn on at times. Any suggestions?
check ypur cap and rotor if you have one
I HAD MASSIVE COLD IDLE PROBLEMS, WHEN WARM IDLE OK, SO CLEANED MAF SENSOR-MUST USE maf sensor cleaner, read directions, next problem still existing was acceleration, that was the EGR VALVE, pulled out and cleaned with carb cleaner, problem solved, now getting MAS sensor low reading on FIXD scanner, so gonna pull and clean, blazer with122k, when i bought it at 60k the K&N filter was gummed, duhhh, thus problems,
Barometric pressure really is it really barometric I don't think it's really barometric pressure barometric pressure needs it's a low atmosphere it's just testing vacuum pressure for throttle response and fuel delivery that's the purpose of the map vacuum sensor they need something that reacts quickly to throttle response the mass airflow sensor doesn't react quick enough
