I'm planning on doing this later, but am confused by one step. What is the purpose of the pipe? You say to "Take you MAF cleaner and put the pipe on it, so you can reach small areas. When you clean the MAF, DO NOT touch anything in side the tunnel with the pipe because that can damage the sensor." ?? Do I spray the pipe and insert it into the tunnels? How do I apply the cleaner to the side of the tunnels without physically touching them? Do i just spray the entire thing down including the tunnels? Can someone please clarify this for me?

the pipe makes the spary more focus and stronger and easier to point.
don't touch anything on the maf when you cleaning it.
don't spray the entire thing, just tunnels.

How do you perform the ECU reset and Idle relearn procedures? I've also heard that some people use brake parts cleaner, it dosn't leave resin. They said that the MAF cleaner will leave that oil on it and it can mess up the sensor later on.

infact, I believe the engine will get used to the cleaned MAF sooner or later, but doing the relearn and reset won't hurt, right?

Hey guys, New-B here though this is my 2nd maxima. I have a 2000 SE 5spd. Prior to cleaning the MAF using the steps above I had a CEL, intermittent stalling and a code P0430. I used my friends Snap-On Scanner to look at the O2 sensors and Bank 1 sensor 2 was "frozen" After cleaning my MAF and driving approx.20 miles, the CEL and the stalling are both gone. I haven't been able to get the scanner on the car yet to see if bank 1 sensor 2 is actually working or not. Is it possible that a dirty/contaminated MAF could have caused the code and the stalling. Thanks for entertaining a new-b question.

Hey New-B here, I did let the MAF dry completely before re-installing it. I have driven the car about 45 miles now and the CEL is still out however on the way home today, the car started stalling again as soon as I put the clutch in. The wierd thing is, if I shut the car off for about 1 minute or so and re-start it, the car idles fine. Any ideas before I resort to the dealer????

I have a thread on it here:

don't want hijack this one. btw, this is a great thread with good pictures, Jason. I'm definitely glad I cleaned the MAF sensor.

I tried to disconnect the MAF today by pressing on the socket and pulling upwards. It wouldn't budge a bit. Did anyone else have a difficult time disconnecting it? Also, will my car start if I don't do the ecu reset?

it will start.

Thanks for your quick response, I was also a little hesistant of starting this clean up process because I did not know how do the ecu reset (kept failing) I will try again later.

I hope you don't mind me posting a picture in your thread but this is what my thingy looks like ...
I can press the socket and push it down at the same time. I tried to pull it out in every way possible way but seems like its not going to let itself go. Any suggestion?

Push a small flat head screw driver inside that space behind the tab, and push it towards the top of the picture and pull it up with your other hand. It's opposite of everything you would expect from a connector on this car.

thanks for the write-up. I'm a firm believer in cleaning MAFs but I think i've been doing it wrong.. Last time i had the MAF out of the car, i just sprayed the little wire/resistor bit thinking that would do it.
If one runs the stock airbox/filter, what are the chances the MAF will even get dirty? My 2002 has been bogging for years now.. I would estimate its down a good 30-50hp, just haven't had time to investigate the issue since (until recently) it's been the wifes car. Now that it's my beater, I've got to de-woman-abuse the car one thing at a time.
