How to clean Mass Air Flow Sensor and Throttle Body on Infiniti QX80 without LEARNING

[@1StevenValdez1]

I've had my G37 for over 8 years now and have left the throttle body connected cleaning all inside and outside with a rag and have never had a issue with rpms afterwards. Going to do the same on my QX80 today. Just thought I stopped by and see if people still worry about that on this platform. At the end of the day it's another VQ so I'm going to do the same

[@dougdrefus4274]

i think you can turn the key on and hold down the gas pedal all the way, that opens the throttle plate, then clean the throttle plate

[@enduranceogie4519]

Very concise video. Thanks!

[@charltonlaird]

Hi I just cleaned the throttle body over the weekend per your video instruction and afterwards on acceleration my RPMs were jumping all over the place. Did the relearn procedure and it seemed to straighten everything out. But still have some hesitation. Wondering if I take off the entire throttle body to clean the other side well and then complete the relearn if that would make a difference? Just wanted to see if you’ve gone this route at some point. Also saw in another video you replaced the Mass Airflow Sensor. Was it acting up after you cleaned it? Thanks!

[@bobbyheenan4061]

You can press the accelerator pedal to open the butterfly. You can also get in there with a rag and clean the butterfly as much as you wish, then just fillow the idle "re-learn" process.

Same as 2015 armada?

[@tronmakaveli3069]

From this video back to the first you made , i did the throttle it does still, it had to be about the transmission i got an code p181b imma try changing oil not flushing it would cause slippage even though its still possible because no if hasnt been changed, hopefully it wouldnt be the torque which i saw a video doing our same problems thanks for the efforts you done

[@alessiaschneider5530]

Thank you. This video was very helpful.

[@Reesemaxx23]

Mine just started doing that never had it done before got a 156,000 miles on mine hopes this works

[@dirtdiver17]

Ok. two things...does this work for an Infinit Q40 that has two air filters. Second, do I turn on the car and then spray and cut off after I spray... Can I do this even if I am not having any problems with the car. Do you recommend doing this after I can the filters?

[@Deja-vu-du]

I’m having the same hesitation that you are describing. But I notice this hesitation at 1300-2000 RPM. It’s as if the rpm needle is floating or being suspended in mid air while going up RPM. Is this the same problem you had before ?

[@Deja-vu-du]

Just a quick update on my situation. We ended up having a faulty throttle body. The difference is night and day. The RPM was hesitating really bad at 1300-2000 rpm. It was not a cheap fix as I wanted the OEM throttle body. But it’s fixed, FINALLY.

[@robertjoo8271]

@@Deja-vu-du I'm experiencing the same issue, but b/c it's intermittent I'm having trouble documenting it. Did you test drive it w/ a tech? How did you describe the issue to the mechanic? I don't want to be in a situation where they say the issue "can't be replicated" so you're SOL.

[@ofcbob6391]

@@Deja-vu-du Did you have any check engine light when you had the problem with the faulty throttle body? Are you talking about the plate not opening correctly?

[@Deja-vu-du]

@@ofcbob6391 so I never had a check engine light at all. We finally solved the problem after changing the transmission oil. That what was causing the issue. The car only had, 75k miles if I remember correctly.

[@timothyevans9228]

The part you said dnt fast forward, I missed that part an I pushed it in to see how dirty it was. Please tell me I didn’t mess anything up. Or what should I do next

[@myathletesbody]

I noticed that you did not scrub the inside where the black residue is built up. I have been doing this same procedure on my Land Rover Lr3 and now my QX80. As long as you dont open the throttle Body plate completely, you will be fine. Also ,I used a new wire brush to scrub the residue, then wipe clean with a rag. Never had a issue. Good luck!

[@cbatilo]

Thank you very much for watching and feedback!

[@timothyevans9228]

What will happen if you open it halfway

Thank you

Which one is the bank 2?

[@luisthepanamanianinlouisvi2968]

Hello, Where is the MAP sensor located on that vehicle?

[@FrankGina2016]

Great video!! I’ll give it a try.

[@MrBergetti]

I have a few questions for you regarding the throttle plate 1. If in ACC mode and you step on the gas pedal, does the throttle plate open and stay open? If it does, it would make cleaning all around it a breeze. 2. If I disconnect the battery and wait an hour or so before manually opening the throttle plate will that not be okay? It shouldn't cause any fluctuations in idle afterwards. What are your thoughts on the two ideas?

[@BillSW]

did u get answers

[@DAnny423h23]

Question is, how often does the cleaning have to happen to avoid the car from doing that

[@charleshudson4162]

I cleaned mine like this...exactly like this... and damaged the Sensors. Gently sprayed them and it was enough spray force to screw them up. (2018 infiniti q50 $300 each, I have two)Be carefull people doing this method to clean MAS sensors. My mechanic said this is a very risky way to clean them because they are very very sensitive. Just don't spray too close or saturate them with too much cleaner.

[@eddiewilson2197]

After changing the throttle body how do you reprogram it

[@cbatilo]

Search in you tube infiniti learning or re-learning. There are plenty of videos of that. My title of my video included "without learning"... it is funny for some people as they think "without getting something out of this video"... but once the throttle bidy get touched or repalced in your case... the car system needs to re-learn. Good luck. If you can find what your are looking for doing youtube search... hit me up again. I know I have made notes / manual on how to re-learn. Thank you for watching and question.

[@eddiewilson2197]

@@cbatilo thanks I found it yesterday and it worked perfectly 2017 qx80 one try👌🏾

[@misterbulger]

I took mine off and wiped it with a seafoam rag. Woops. Did that wreck it?

[@mr.lemaire5598]

Hello, I follow your direction..Cleaned the Air flow sensor like the video, now I think my issue happen when I star cleaning the Throttle body, I was trying to turn on the accessory ONLY, But I accidentally pressed the break and started the vehicle... I immediately turn-off the Truck. I remember vividly at the 4:26 mark, you insisted to NOT start the ENGINE... I continued spraying the cleaning solution in there and when I closed everything and went to restart the truck, now it doesn't start? ANY assistance PLEASE... What do I need to do in order to start my truck? ANY Suggestion or Help will be appreciated...

[@cbatilo]

Did you try disconnecting the battery yet? Reset / reboot. If that did not work... (not a joke) for real search in KZbin: infiniti learning procedure relearning

K%N airflow is a best choice. Honestly..

Hi does anyone know what that orange tool he is using is called?

It is just a Philips head screw driver

[@albertoparedes9926]

Check engine came on and still have the same problem 😡

[@bisharakhoury9299]

I have the same issue mine too check engine came out

[@leonida9771]

You have to clean the inside of the plate, all dirt is inside not outside..

[@MrPatdeeee]

Amen, amen and AMEN. He needs to remove the Throttle Body and clean the back side of the throttle thoroughly. Most do not do this and it is why the cleaning doesn't last long. Because as you say, "all dirt is inside not outside". I believe you meant, "MOST all dirt is inside not outside". There is dirt (carbon) on the inside and outside of the flapper, but MOST is on the inside. That is almost impossible to clean thoroughly, if you do not remove the Throttle Body and clean that back (Inside) of the throttle body. For what it's worth.

[@theoneandonly1802]

First I spray where I see dirty and then I carefully use toothbrush lol.

[@alan4sure]

I tried that but the brush tasted terrible after that. Bad idea 😁

[@Chevy-hw6lw]

Have you ever personally used isopropyl alcohol or brake cleaner to clean maf sensor or throttle intake. ? I have. Since the 1990’s. It doesn’t damage them, just another product to make money off people . Not trying to be a prick , just the truth .

[@805fpv3]

This is really cool , we need more people like you God bless :)

[@jakaden5]

I used alcohol on my MAF and no issues

[@ofcbob6391]

You can use throttle body cleaner too....you just have to make sure it air dries completely. MAF cleaner evaporates rapidly.
