MAF cleaning
Hey guys,
i'm having trouble coming across a good tech article about cleaning the MAF. From my understanding, K&N filters have oil on them and it gets sucked into the intake and covers the MAF sensor with residue. Am i only supposed to clean the sensor or should i be cleaning out the intake tube as well? i'm assuming the oil has deposited on the intake tube walls as well...
so what do you guys usually do for this procedure?

And yes you can clean the tubes..might as well clean the throttle body and tps while you are there.

I came across that 4x4wire one and it was good. good details about the sensor but just nothing on cleaning the whole thing. but like you said, might as well clean all of it. does the MAF cleaner work for cleaning the throttle body or is there a throttle body cleaner i should use instead?

clean the maf sensor with something that does not leave a residue such as electronics cleaner or maf cleaner. Throttle body spray works great for everything else.

this will damage the sensor. they cannot take much pressure or bending.
the wires....if they are bent in the slightest they become uncalibrated and will forever send an improper signal. prob not enough to run poor, but improper nonetheless
you really should use spray and never touch the wires with a tool

I believe checker or auto zones sells MAF spray cleaner. thats where i purchased mine. i wouldn't gamble using anything else other than the MAF spray, sure something like carb cleaner might work but why chance it with a 100+ part.

One of my instructors has us spray the MAF real good with Brake Kleen or similar and then with an electronic contact cleaner. I did that with a 98 4runner with a totally plugged up MAF (they took it out to burning man...even had a stock intake and filter!!!!). Haven't heard of a problem since then.

I am not too sure about cleaning the TPS... I have chalked my faulty TPS problems up to getting too much carb cleaner in it actually. I have read in a few places that carb cleaner is bad fro the TPS. So keeping that in mind, make sure not to totally soak the throttle body in carb cleaner. Just spray some onto a rag and use that to wipe it clean.
But yes, dont douse the throttle body in solvent. Just soak a rag.

Yeah on the 5VZFE, or at least the 97 model 5VZFE, there was no calibration or adjustment needed. Just make sure that the sensor "hooks" up to the throttle body butterfly arm thing correctly. Sorry, I don't know the technical terms for that but if you replace yours, you will see what I am talking about.

Oooh, I took my throttle body off when I changed mine which made it really obvious as to how it needed to go on. If you are going to do swap it with the throttle body on, you might want to wait for some expert advice
From what I remember, you can't push the TPS onto the throttle body having the screw holes lined up. You will have to turn it some, push it on and then turn it to line the screw holes up. It's probably much easier if you take the TB completely off but I think you can get the job done without. I mean you've got over 1800 posts on YT, you must be an expert wrencher right?

Im not too worried about it, but just like having as much knowledge before I do it. Through my searching I found one thread referring to the orientation of putting the sensor back in respect to the butterfly valve. And by seeing from your other threads that you recently changed it out, I might be able to get the insight I needed.
Thanks for the help. Especially in hijacking the OP thread. But at least his question was answered.
