When I had my P1128 several years ago, I read the code on my hand held unit and looked it up in my Accent service manual and noticed there were a bunch of things it could be beside the MAF, I thought it was the MAF.

I went to the dealer, I mentioned what I found and all the things it 'could' be -- he said right away MAF.

The cost was covered at that time.

Maybe your DEALER must use a more involved testing machine to determine?

Or maybe the 'China' replacements are not that cool.

I think I read somewhere that if the MAF acts up -- unplug the connector and the computer will go in a 'soft-fail' mode and the car will run. I guess if it runs better, the MAF has a problem.

Double check on all this.

My gut tells me the MAF is fine because: #1 I got it directly from the manufacturer in China and it's definetly not a rebuilt!

Anyone want to buy a 2000 Accent 4dr, Red w/spoiler, CD player, and only 70K miles???? :w00t:

 

should have cleaned the MAF before replacing it.


print off the service flowcharts from hmaservice.com and dig in.

 

I keep hearing "clean the MAF" but how do you clean it where it lasts longer that 2 weeks?

tr

 

I cleaned mine over 2 months ago and it solved my fuel system problems. (threw a code once every couple of days, havn't had one since)

I used alcohol at first.. then sprayed it with brake cleaner.

 

I did the brake cleaner treatment...no luck. Also, no salvage yards had any. The problem with this P1128 (I believe) is that it's anotehr one of these maufacturer codes that simply is a "Dealership Cash-Cow" :amen:

 

ok thanks BH-206:

Is it easy to take apart?

Do you have to remove the whole MAF assembly or can the sensor just be removed?

With alcohol -- I think you would use clear isopropyl either 70% or 90% -- probably 90% would be better?

What does the sensor look like inside it's guts? The part that you would clean?

tr

 

I took just the sensor out of the piping. I used a hacksaw to cut a slot in the weird screws so I could just use a flathead screwdriver. After that I Did-Not take the maf apart what-so-ever. I thought about it and even tried but I didn't want to break anything. The higher the better for alcohol. I only had 70% handy though.

The sensor has three parts.. the exposed part has a little wire that runs around a bit on the side. In the middle there is a flat metal surface sensor that goes through the sensor, and at the top there is three metal prongs one after the other.

In the end I was just feeding all three with brake cleaner.

 

Hi BH206:

I saw on the internet CRC Industries has a specific cleaner just for the MAF sensor.

It's: CRC-05110 $6.99 spray can.

Are the screws that look weird -- are they torx ?

tr

 

whatever cleaner you use, it can't leave ANY residue.


yeah it's Torx.

 

Hi BH206:

I never took one apart, is the sensing done by using the 'hot wire' or 'film' approach?

tr

 

you don't need to take it apart.

i'm not sure. it has what I believe would be the 'hot wire' on the side, a flat metal peice running through the middle, and three prongs inside at thetop.

 

And I guess it would be safe to assume that you spray (with a suitable cleaner) the 'hot wire' only to get off or remove any residue film or particles that are clinging to it.

tr

 

I sprayed the **** out of the whole thing with brake cleaner. I think I went to town..
