Never use anything but maf cleaner, cleaning is only a temporary solution,
sensor components located in the top plastic housing are usually the fault.
Spend the hundred bucks or so and get a new one or you will pay at the fuel
pump.
get ya a pack of driver bits for 5 bucks
The reason they tell you not to touch the sensor wires is because they will
break easily or if you leave oil or fiber contaminants behind they could
cause the sensor wire(s) to fry as they cook off. As he noted in the video
the wires heat up. That’s also why youn should leave it to dry before
reinstalling. I don’t see any harm in using pain thinner as it is
non-corrosive. Carb and brake cleaner gases become corrosive when heated.
That screw is a Secure Torx T20 bit, can be bought at any auto/parts/tool
store. Canadian Tire, NAPA, Part Source, Princess Auto or whatever kinda
store you have around should have it. Maybe even a Home Depot or something
but I know auto stores definitely have them. Secure Torx because it has the
hole in the middle of the bit and T20 is the size. Don’t get a normal Torx
bit make sure you get SECURE TORX.
acetone works fast and much better…
Ford says to NEVER use paint thinner or anything other than CNC electrical
cleaner!
How the fuck do you know the paint thinner wont hurt it? You don’t.
This is also. A good way to damage the sensor
Or you can just buy a can of MAF sensor cleaner for $4 and do this job in
30secs
I had a bad spark knock in my 2000 Ranger 5 speed . Tried a lot od
different things to get rid of it . Changing the thermastat from 197 Degree
to 180 degree stopped the spark knock and the truck is running great.
Are you a douche bag, Perk E is absolutely correct
from your fuel trim numbers. A good visual inspection of your engine can
yield valuable info, sometimes it’s just a vacuum line that popped off.
What this guy is showing people is what not to do. This is some shit
farmers do on old junk farm trucks and shit, NOT someones daily driver.
bring it to a garage, sometimes maf sensors will be bad and not throw a
code, Maf sensors are frequency generating sensors,(wires are heated to
392degrees f as air goes across they cool down and it needs more current to
maintain the temp, there for creating different frequency.)so sometimes you
will get signal drop outs, you will not get proper frequency ranges,etc.
The only way to properly diagnose these are with a lab oscilloscope. Also
if its running lean you can find out alot of information
And thats if your lucky. A new one for my T-bird is $167, or a refurb for
around $120.
Don’t worry your Ford will die either way. My 2010 E150 just blew out it’s
second spark plug and I had to be towed for the second time now at 209,000
hiway miles. I HATE FORDS
Thanks for the tip, the maple syrup worked!
Thanks! That’s just the way it goes. Not the first time I’ve caught heat
for thinking out of the box 🙂
Check for vacuum leaks too. Also the fuel filter. Good luck!
Thank you ‘Jennies Garage’, don’t worry about these haters, If they knew
how to do it today wouldn’t be watching these videos now would they?
Thanks for this. My Focus MK1 is bumpy on idle and I think the MAF is at
Fault. OBD says the system is too lean!
good vid but why not just buy a new one? are they that expensive?
Those sensors are 110.00 dollars
Thanks! Sometimes one has to improvise to keep on truckin’
Nice bolt removal freestyle! Those skills are needed for working on cars!!!
Sensor looked good too/
“Always use the correct driver” I didn’t have one, and my method, although
crude, got the job done. “Never use paint thinner” Why? It won’t damage the
sensor wire, and will clean off years of burnt-on residue. “Never touch the
wire” If the sensor hasn’t been cleaned in 200k miles, scrubbing it may be
the only way. “The spray is all you need” That may work if you have
religiously cleaned your sensor since new at every oil change, but not one
that looked like mine. BTW my sensor is working fine…
dont mess with the maf sensor or its going to run like shit
Wow….talk about a shadetree mechanic….15 seconds in and I was
disgusted. Cryptic torx with a stub? Try Tamper-Proof Torx. Who loosens
screws that small with vice grips and a razor blade??!! Don’t listen to
this guy, you’ll hurt yourself.
You might as well dip it in Maple syrup! Also add some Maple syrup to the
tank to clean the injectors while your at it…Paint thinner…250.00
mistake right there folks!
You did not say what year the ranger is and you should have had the engine
running for a before and after. But otherwise a great little video…It may
have helped me solve the condition code p1120 and p1120 from the (Mac tools
scan codes). All about fuel and air mixture. My truck now has 204k it is an
02 ranger. I say these things for others who may come and see what is up
with the MAF TPS
Glad you enjoyed the video, and thanks for the info about the bits!
Hello, jenniesgarage. Thanks for the info! By the way, I have a set of bits
for those particular screws and they are officially called Security Torx
screws. Just FYI. Thanks again.
Have the code read at an auto parts store. You may have an EGR issue, as in
low EGR flow.
Thank you …kind of you…
I’m happy to help, thanks!
Also known as a “pin-in Torx” head. FWIW.
Give those nails a trim
this is the exact opposite of what u need to do. why not just buy the MAF
sensor cleaner
Good idea! I was also thinking of using a dremel with a cutoff wheel to
slot them so a falt blade screwdriver would work. Thanks!
Happy to help out!
My truck is sending a code that it is running lean on both banks. Cleaning
this turned off the engine light for about 5 min. Would replacing it solve
the problem?
Why couldn’t you cut slots in the screws with a hacksaw or dremel? No more
problem– just use a small flat screwdriver from then on.
Glad you enjoyed it, happy to help!!
Thanks for the info! I was lucky enough to remove them with the pliers, but
the proper tool definitely would’ve come in handy!
how many miles on your cars?
good vid, just wondering if instead of using q tips try carb or intake
cleaner to wash off the carbon?
Why don’t he just buy sensor cleaner that sprays on- that’s formulated for
this job?
I actually cleaned my throttle body today and now it runs worse. Idling at
300 to 800rpm before stalling out.
I think it’s always good to allow the sensor to air dry before
reinstalling.
