The "MAP" spray cleaner you mention above on Amazon is listed as a MAF sensor cleaner is it OK to use on a MAP sensor without damaging the sensor. I have a Jeep with a MAP and temperature air sensor combo, would that MAF sensor cleaner also be OK for that sensor??
There's no dedicated MAP sensor cleaner. MAF sensor cleaner is as mild and effective as it gets, and can be safely used on the MAP and other sensitive electronics. Yes, you can use it for the indications you referenced.
Nice tutorial Sir, thank you............I shall do this soon on my isuzu diesel 4x4..............I wasn't sure whether you could clean the inside of the sensor............thumbs up and subscribed !
Thank another question for you please? I sprayed electronic cleaner inside the rubber hose that goes in the map sensor on a 2000 Toyota Camry 2.2l. Tie wraps are holding the Map sensor together. Cleaned it and going to put electrical tape and tie wraps again and see if the check engine light goes off. I did not disconnect the battery prior. Afterwards I did, hope I didn't harm anything. I like your videos!!! Great job 👍👍
You would have a vacuum leak from the non-perfect seal since you use tie wraps. You will need to scan the car to identify why the check engine is on. The electronic cleaner as long as it is written safe on plastic/rubber will not cause any issue. Thanks for the compliment!
I tried using a screw extractor, but sadly that didn’t work. Hopefully I have enough of the head left to use the hacksaw blade to make the line. Thanks for the tip!
that was a nice little trick..I'll have to try that one. If the screw is really fucked, you can also use Epoxy Glue..just put enough on to cover the top of the screw, let it dry really good, then take the hacksaw to it and make your line.
A few questions... Are you having black smoke from the tailpipe? Did you change brakes or tires recently? Did driving style change? If you do not have a CEL, fuel trims STFT and LTFT will tell a lot. There are a lot of things that can cause poor mileage without a CEL. They include: dirty injectors, dirty air cleaner element, dirt MAP or MAF, low tire pressures, dragging brakes, stuck open thermostat, sluggish O2 sensors, leaky injectors, worn spark plugs, faulty fuel pressure regulator etc. You will need to troubleshoot to narrow down to the cause. Would definitely recommend doing tune ups that are due. Any new info?
@@DIYAutoworksNG Hello, I have an Accord 2006. An engine imported from Japan was installed, but after installing the engine, I had some problems when going uphill. The car is muffled. It does not run well when walking on flat ground. It walks perfectly. Maintenance, from changing the ignition and cleaning all the MAF sensors, is it related to the problem of ascent?
I bought a 4 bar map sensor to put in my 2.2 I-CTDI, but as soon as I start the truck, the engine light comes on and through the obd I saw that it is not reading the kpa of pressure. Is any tuning or calibration required to read the values?
Honda usually don't require caliberation for when MAP sensors are replaced? Was what you bought OEM? On critical sensors of the emissions system, I'd stay with OEM except you get the aftermarket variant of the manufacturer that makes the OEM for Honda. Did the old one throw any codes?
Thank you! I don't have MAF cleaning spray or contact cleaning spray on hand --- could I use rubbing alcohol (isopropyl alcohol) in a spritzer bottle and then let the MAP sensor dry out before reinstalling it? Please advise... Much appreciated...
Use the correct screw driver for the JIS type screw that fasten the MAP sensor. JIS-spec cross-head screws are generally marked with a single raised dot or an “X”. ( Note: JIS, or Japanese Industry Standard screws are just different enough in shape that Phillips drivers will not fit well and slip/strip them. The difference is in the leading angle of the point of the driver. Phillips bits have a larger angle and therefore don't bottom out in the JIS screws, causing slippage ).
Read the fine print, if it says it doesn't leave a residue or affect plastic, it should be okay. If it's silent on these, I suggest you go with either rubbing alcohol or MAF sensor cleaner. I have 2 electric contact cleaners from different brands: one clearly states it leaves a protective film, the other just cleans and leaves no residue. I use the either the latter or MAF sensor cleaner. Conincidentally, I met someone who cleaned his MAF sensor with carb cleaner 😳😠😡

Is wd40 spray possibly a reason to effect this sensor?because i sprayed and since then my engine is vibrating and there is alot smoke and very accelrator
WD-40 is not a cleaner and should not be used to clean sensors. I advise you clean it with MAF sensor cleaner or methylated spirit if you have nothing else.
If its the one I think it is (black and silver can with yellow spray top), you're good to go. I was just laying out the specific requirements because I've seen some electric contact cleaners that leave a protective coating (I guess to limit flux formation) e.g. The one from Liqui Moly. You certainly don't want that on a MAP/MAF sensor.
Good day sir please I have not carried out this procedure yet but I want to explain my situation. Sometimes When I put my car in reverse, it engages immediately but when I put it to drive it doesn't engage for some seconds or even minutes, then when it engages, it jerks violently to the gear. Even when driving on the road, sometimes it will not engage and then it engages as if it is not breathing properly. Also theres poor Gas mileage, difficulty climbing uphill or overtaking. Please I will appreciate your response. Thanks.
With what you've described, it sounds like you have a transmission issue. Lack of power on an incline seems like something else. I advise you scan the car first and share codes.
Electric parts cleaner works. You just need to check that it's stated that it doesn't leave a residue. Most of them don't, but came across one at a time that claims to leave a protective coating. You don't want that. The ones that don't leave a residue will have it clearly stated.

I scoured through the entire akilo and agidingbi auto parts markets in lagos, no one knew what maf cleaner was, they were just giving me carb cleaner, i was already considering going to olowu and ladipo markets, I'm glad i came across this channel, thanks a lot man.
I can't get the screws off the MAP sensor, those stupid phillips screws are on TIGHT. I got one off and put some anti seize on it so its snug, but I can't get the other one off. I try some loosey liquid wrench stuff, i might have to cut a line into it with a dremel so I can use a flat head into it. If I can get them off i'm going to replace it with some bolt instead of sticking those stupid screws in.
Agreed, but I still think it's not the best design. I think Honda must have realised this and has since moved away from using screws on MAP sensors. My 2017 Accord has a bolt on it.
No need to replace the connector. Is it loose? There's a zip tie hack. Google "using a zip tie on a broken electric connector" Do let me know if it works for you!
My screw is siezed, so waiting / hoping Tri-Flow will free it. In my case, it's a little hard starting when the engine is cold, and the idle will typically bottom out and stall almost immediately if I don't apply and maintain light pressure to the gas pedal for a minute or two. Longer in cold weather. Once the engine has warmed up and driven a few miles, idles normally, no issues with stalling. Will start and idle fine as long as it hasn't sat and cooled down for more than an hour or two. Despite there being an associated low idle issue, the only engine code which is ever thrown is a "system idle higher than expected". The MAP is probably the original, and most likely never cleaned, so once I get the screw out, I figure it won't hurt to clean it anyway. Hoping it fixes it.
Hoping the screw gets unstuck! With the code you spoke about, I would lean more towards the a dirty IACV(if equipped)/throttle body. Has it ever been cleaned?
@@DIYAutoworksNG I replaced the IAC valve, which fixed a no start / extremely hard start. It would stall at stop signs unless given heavy pedal pressure, and would stall when the wheel was turned as far as it could be. The new IAC valve was like night and day. But it only lasted 6 months like that before the issues I described cropped up. I've cleaned the throttle plates and the opening around them, but I'm leary about taking the whole throttle body apart to clean it. I can do some things, but I'm definitely not an auto mechanic. I'll clean the MAP and see what happens, and then clean the IAC. Thank you for your thoughts 😊
@Jay Yoyo Cleaning the MAP made no difference, having a little trouble finding another one, so I can't comment further on that yet. Your problem definitely sounds exactly like mine, whatever it is. If I figure mine out, I'll definitely update. Hopefully you will too 👍😊
@Jay Yoyo Check engine light is on. I do have a scanner, and that one looks familiar, but I can't say for sure. I'll check it tomorrow. The last one I knew, which was the only one showing at the time (a few months ago) was a "system idle higher than expected" - I don't recall the code number though. I'll check it. Is that the one yours is showing?
On 2017 Honda CRV with 1.5 turbo changed MAP/ MAF sensors problem still exists. Starts fine , idles fine but once you drive it it seems to be holding back and upon pressing the gas pedal it acts like bogging down with no real power. Anyone have same problem?
@DIYAutoworksNG mine is P0172. I've cleaned the intake, cleaned the MAF sensor, but still same symptoms. Runs fine but starts to studder, bad smell and lack of acceleration
Haven't worked on this car before, but principles are the same. I think you just have to Google the location. Not all cars have a MAP sensor. So don't be alarmed if you don't find one.
I wish somebody could help me with a 2001 Hyundai Santa Fe to let me know where the map sensor is located. I like to replace it having trouble with my SUV.
I have no history Santa Fe, however, MAP sensors are almost always just after the throttle body on the intake manifold. Also note that not all cars have a MAP sensor. Do you have a MAP sensor code?
Yes. It should go away after completing a number of drive cycles. However, people often go the other way round by clearing the CEL first and waiting to have the ECU confirm the fix by not turning on the CEL.
Hello So many things can cause hesitation apart from the MAF sensor. Have you checked for vacuum leaks on bank 2? Fuel supply issues too are potential culprits. What car?
You can use any quick drying solvent that doesn't degrade plastic/rubber and leaves no residue. Examples are MAF sensor cleaner, electric contact cleaner (be sure that the the criteria stated above are written on the body of the can). If you have none of those, you can use rubbing alcohol or methylated spirit as a last resort.
Nope. Carb cleaner will degrade plastic/rubber and also affects sensitive electronics... If you don't have MAF sensor cleaner or electric contact cleaner that doesn't leave a residue, use rubbing alcohol.
I wouldn't use that personally, I would say MAF cleaner or an electric parts cleaner that states that it doesn't leave a residue. If you have none of these, my next pick would be rubbing alcohol.
The screw not actually rusty but it is a JIS-spec cross-head screws are generally marked with a single raised dot or an “X”. ( Note: JIS, or Japanese Industry Standard screws are just different enough in shape that Phillips drivers will not fit well and slip/strip them. The difference is in the leading angle of the point of the driver. Phillips bits have a larger angle and therefore don't bottom out in the JIS screws, causing slippage ).

Bro it looks like you're in Nigeria, please can you help with the name of contact cleaner you used, I've checked several auto parts markets in Lagos for maf cleaner and couldn't find a thing
Affirmative on Nigeria!
Found CRC MAF sensor cleaner on Konga. www.konga.com/product/crc-mass-air-flow-sensor-cleaner-11-wt-oz-3800952
I've also used this cheaper but effective ABRO product in the past. Still do. jiji.ng/lagos-island-west/building-materials/abro-electronic-copy-contact-cleaner-pCwnPFJ6oGdjKIgFjtcJ3pbp.html?lid=p1PSDr7wBWMTYrgD&cur_pos=3&pos=3&ads_count=3&ads_per_page=3&page=1
@@DIYAutoworksNG ohhhh, why didn't i check online🤦♂️!
I scoured through the entire akilo and agidingbi auto parts markets in lagos, no one knew what maf cleaner was, they were just giving me carb cleaner, i was already considering going to olowu and ladipo markets, I'm glad i came across this channel, thanks a lot man.
You're welcome!
I can't get the screws off the MAP sensor, those stupid phillips screws are on TIGHT. I got one off and put some anti seize on it so its snug, but I can't get the other one off. I try some loosey liquid wrench stuff, i might have to cut a line into it with a dremel so I can use a flat head into it.
If I can get them off i'm going to replace it with some bolt instead of sticking those stupid screws in.
Cutting a slot for a flat-head is your best bet for getting it out. If you get a fitting bolt afterwards, that would be great. Bad design by Honda.
Its a JIS-cross head screw, not the normal philip cross screw use the right type cross screw driver for it.
Agreed, but I still think it's not the best design. I think Honda must have realised this and has since moved away from using screws on MAP sensors. My 2017 Accord has a bolt on it.
This car have both sensor MAP & MAF?
This 2003 Accord has just a MAP sensor.
Thank you sir!
You're welcome!
Anyone know or have a video to replace the map sensor connector? My clip on it broke. Any suggestions or ideas?
No need to replace the connector. Is it loose? There's a zip tie hack. Google "using a zip tie on a broken electric connector" Do let me know if it works for you!
@@DIYAutoworksNG I see. How would I remove it when I need to remove/unplugged the sensor?
Depress that tab that enables you loosen a zip tie
@@DIYAutoworksNG can you send me a video of how to?
Just search "using a zip tie on a broken electric connector". There loads on TH-cam
My screw is siezed, so waiting / hoping Tri-Flow will free it. In my case, it's a little hard starting when the engine is cold, and the idle will typically bottom out and stall almost immediately if I don't apply and maintain light pressure to the gas pedal for a minute or two. Longer in cold weather. Once the engine has warmed up and driven a few miles, idles normally, no issues with stalling. Will start and idle fine as long as it hasn't sat and cooled down for more than an hour or two. Despite there being an associated low idle issue, the only engine code which is ever thrown is a "system idle higher than expected". The MAP is probably the original, and most likely never cleaned, so once I get the screw out, I figure it won't hurt to clean it anyway. Hoping it fixes it.
Hoping the screw gets unstuck! With the code you spoke about, I would lean more towards the a dirty IACV(if equipped)/throttle body. Has it ever been cleaned?
@@DIYAutoworksNG I replaced the IAC valve, which fixed a no start / extremely hard start. It would stall at stop signs unless given heavy pedal pressure, and would stall when the wheel was turned as far as it could be. The new IAC valve was like night and day. But it only lasted 6 months like that before the issues I described cropped up. I've cleaned the throttle plates and the opening around them, but I'm leary about taking the whole throttle body apart to clean it. I can do some things, but I'm definitely not an auto mechanic. I'll clean the MAP and see what happens, and then clean the IAC. Thank you for your thoughts 😊
I see! Let us know how it goes!
@Jay Yoyo Cleaning the MAP made no difference, having a little trouble finding another one, so I can't comment further on that yet. Your problem definitely sounds exactly like mine, whatever it is. If I figure mine out, I'll definitely update. Hopefully you will too 👍😊
@Jay Yoyo Check engine light is on. I do have a scanner, and that one looks familiar, but I can't say for sure. I'll check it tomorrow. The last one I knew, which was the only one showing at the time (a few months ago) was a "system idle higher than expected" - I don't recall the code number though. I'll check it. Is that the one yours is showing?
On 2017 Honda CRV with 1.5 turbo changed MAP/ MAF sensors problem still exists. Starts fine , idles fine but once you drive it it seems to be holding back and upon pressing the gas pedal it acts like bogging down with no real power. Anyone have same problem?
Any codes?
@DIYAutoworksNG mine is P0172. I've cleaned the intake, cleaned the MAF sensor, but still same symptoms. Runs fine but starts to studder, bad smell and lack of acceleration
@@richlive11could be 02 sensor
Sir what does PS means on Map sensor... like 33 PS, 30 PS?😊
I honestly don't know. Lol. Looks like part of a code to me.
Thanks
You're welcome.
I need to no how to clean map sensor on 94 Chevy 5.7 liter
Haven't worked on this car before, but principles are the same. I think you just have to Google the location. Not all cars have a MAP sensor. So don't be alarmed if you don't find one.
My pump is starting now but it doesn’t get gas and my air mass sensor air intake got burnt
I don't understand.
Sorry man haha
I wish somebody could help me with a 2001 Hyundai Santa Fe to let me know where the map sensor is located. I like to replace it having trouble with my SUV.
I have no history Santa Fe, however, MAP sensors are almost always just after the throttle body on the intake manifold. Also note that not all cars have a MAP sensor. Do you have a MAP sensor code?
I got 2 codes for my car and it’s hard going up hills and my car will drive ok then rough then ok then rough
Have the car scanned, a number of things can cause this.
*These OEM sensors go for about 140, I got Mines for $100 at honda not everyone will get that deal*
It's cheaper online. See www.hondapartscheap.com/oem-parts/honda-sensor-assembly-map-37830pgka01?c=Zz1lbmdpbmUmcz1pbnRha2UtbWFuaWZvbGQtbDQtMDUmbD02Jm49QXNzZW1ibGllcyBQYWdlJmE9aG9uZGEmbz1hY2NvcmQmeT0yMDAzJnQ9bHgmZT0yLTRsLWw0LWdhcw%3D%3D

That's a lot!
Nobody shows how to clear Check Engine light or will it go away by itself after MAP clean or replace?
Yes. It should go away after completing a number of drive cycles. However, people often go the other way round by clearing the CEL first and waiting to have the ECU confirm the fix by not turning on the CEL.
p0174 my car has no maf sensor???hesattation
Hello
So many things can cause hesitation apart from the MAF sensor. Have you checked for vacuum leaks on bank 2? Fuel supply issues too are potential culprits. What car?
To cheap to put a new bolt on your map sensor?
who cares its one tiny screw
Por que a mi m lo marca p2227 sensor map
Can be poor contacts, shorted wiring, dirty or bad MAP sensor. Also dirty air filter in some cars. Worst case scenario, a bad ECU.
No.problem if I use electronic cleaner
Sounds good as long as it doesn't leave a residue.
@@DIYAutoworksNG thanks
Wd 40 electric contact cleaner
That would work
Please what's the name of the chemical used in cleaning the map sensor
You can use any quick drying solvent that doesn't degrade plastic/rubber and leaves no residue. Examples are MAF sensor cleaner, electric contact cleaner (be sure that the the criteria stated above are written on the body of the can). If you have none of those, you can use rubbing alcohol or methylated spirit as a last resort.
Can i use WD40 for cleaning map.sensore
Not at all. Look for MAP sensor cleaner or rubbing alcohol if you are in a bind.
@@DIYAutoworksNG can you use carb cleaner? I already did anyways but i think mine might be bad after i did that lol
Nope. Carb cleaner will degrade plastic/rubber and also affects sensitive electronics... If you don't have MAF sensor cleaner or electric contact cleaner that doesn't leave a residue, use rubbing alcohol.
Can I use throttle body cleaner? otherwise I just have some alcohol
Throttle body cleaner contains acetone which damages most plastic & rubber. Will rather use alcohol.
@@DIYAutoworksNG okay I will try with rubber alcohol
👌🏼
Can I use brake parts cleaner
I wouldn't use that personally, I would say MAF cleaner or an electric parts cleaner that states that it doesn't leave a residue. If you have none of these, my next pick would be rubbing alcohol.
Must be change map sensor about 100 000 km 🚘!
First step should have been to disconnect the negative battery terminal. Oh, you should have changed the screw that was rusty. Lol
The screw not actually rusty but it is a JIS-spec cross-head screws are generally marked with a single raised dot or an “X”.
( Note:
JIS, or Japanese Industry Standard screws are just different enough in shape that Phillips drivers will not fit well and slip/strip them. The difference is in the leading angle of the point of the driver. Phillips bits have a larger angle and therefore don't bottom out in the JIS screws, causing slippage ).
Carb cleaner won't hurt a thing😂
It'll degrade plastic over time. It won't do it immediately. Can also mess up the sensor readings.
Never buy after market parts. If you car takes Delco buy Delco it will save one tones of headache.
Gospel!
C’mon, man. Change the worn screw with a bolt!!!
Considered it, but didn't have the same size bolt at the time. I've since sold the car though.
