How to clean up the MAF Sensor?

[WhiteSnake74]

Hi,

I want to clean up the MAF Sensor because I had to replace the K&N FIPK filter cause it broke.

How do I do it?

I think I read a post a few weeks ago that you can use Electric Cleaner. Is that true? Where can I find that cleaner?

Thanks!

There is actually a MAF/sensor cleaner as well. I just use that on all the sensors in the intake. Works amazing! I think I got mine at Kragen

CRC makes one.

I use this stuff too.

You may not be able to find this where you are (PR), you can use electric contact cleaner too.

:beer:Go to svtsnake.com .There is a good write up on cleaning the MAF and what product to buy at Autozone. The write up is by mike79

The screws that hold in the MAF are security torx and they have blue threadlock. I stripped one of the screws because of the blue threadlock. Use a soldering iron on the head of the screw to melt the threadlock prior to attempting to remove the screws. Use CRC Quick Drying Electrical Contact Cleaner from AutoZone or a cleaner that says MAF on the can. Be extremely careful with the MAF its fragile. Remember to reset your PCM after cleaning. Good luck.

Why wouldn't you just clean the MAF wires inside the housing? that's how I do it.

How do you reset the PCM??? Disconnect the batt???

I guess I just never thought of it, great idea :beer:

Why does it need to be reset? I've never reset it when I cleaned the MAF...is that bad? :shrug:

I have a 6-Piece Security Torx set (T10, T15, T20, T25, T27 & T30). Can I use it? I don't what you mean by blue threadlock.

The screws that hold the MAF on have threadlock on them. This makes the screw hard to remove. The screw goes into a brass nut that is captured in plastic. Its real easy to break that brass nut free from the plastic. So heat the head of the screw with a soldering iron to melt the threadlock before attempting to remove the screw.

You should be able to use your security torx I do not have the size of the MAF screw memorized so I cannot tell you for sure.

The reason for resetting the PCM is to force the PCM to more quickly learn new fuel trims for the MAF after it has been cleaned it will read differently especially if it was really dirty.

How long do you keep the batt un hooked before re-starting the car??

 

[WhiteSnake74]

I think that 15-20 minutes.

 

[WhiteSnake74]

Ok, I got the CRC Mass Air Flow Sensor Cleaner on Advance Auto Parts.

Thanks for all your help!

It will reset after 3 min or so. I leave it off for five...then turn it back on. I had to do this a lot when I had my fuel gauge malfunction.

Already cleaned up the MAF. The wires were definitely a little bit dirty. They had a tan/light brown color. Now they look very shinny. That CRC MAF Sensor Cleaner is great!!





Now, I have a question, there is another sensor between the MAF and the throttle body. I also put a little bit of the CRC MAF Sensor Cleaner just in case it was dirty too. What is that sensor? Here's a pic.

I may be headed this route when I get my JLT RAI in the mail. :rockon:
