So I finally located the MAF which sadly hurt my pride, because this looks far more technical than what I had hoped.
I am far from mechanic my Field work is child care at home it's just me and my teen. Moving on here's what I plan to do based from others DIY mechanics.
Discharge batter
Unplug the cable thingy on top of the MAF
And unscrew two screws (or should I not)
Now what should I be cleaning with the spray?
Will it just come out
History The starter was replaced 2 years ago then the alternator last year my battery is new.


So there's this MAF which is not on the intake manifold like most cars. Given this area is cleaning it the same and is this an easy removal as I planned?
Hey now that I thinking of this battery is that its not for this car.
Would it be better to buy the right battery the one I have is from a Toyota scion 2004 hatchback. And maybe this is why I am having power problems?? Would this also cause a code p101 ?

 

The battery will have no relation to the P0101 code for the Mass Air Flow Sensor. And disconnect, don't "discharge" your battery...

There are a number of things that can cause the P0101 code, but checking and cleaning both the electrical connections to the MAF and cleaning the wires/elements inside with MAF sensor cleaning spray are a good start. DO NOT touch or stick anything inside other than spraying the cleaner through it. I remove the wires, unclamp the clamp holding both sides of the MAP to physically remove it. I then hold it over a trash can while I spray the MAF sensor cleaner down through it, so that all that stuff has a place to drip. Once it dries, reinstall it and reconnect the wires.

Other things to check if that does not do it are your air filter, as well as for both leaks AND restrictions (like a dirty air filter) in the air intake to the engine. And vacuum leaks, but those can be tricky to find.

The only time I had a MAF sensor code, I actually had to replace the MAF sensor to get the engine running right again.

Good luck!
