#3258 of 3260 Re: DTC P0101 MAF or VAF chk performance [fixitrod] by rsht Apr 28, 2009 (5:39 am)
Replying to: fixitrod (Apr 24, 2009 1:29 pm) VAF stands for Vane Air Flow, I heard some call it the Vortex Air Flow ... With the P0101 code, I would try to clean the MAF sensor area first (only use the spraying force from a spray can to clean the sensor area, Do not brush or touch it, see picture in the second URL below), its a good idea to remove the MAF unit from the vehicle for cleaning. Make sure all is dry before installing the MAF unit back on. http://www.crcindustries.com/auto/content/products_ss.aspx?ID=90 http://www.tccoa.com/club/parts_pics/maf.jpg (for illustration purpose only) Replies to this message: fongerelli (Apr 28, 2009 7:02 am)

Replying to: rsht (Apr 28, 2009 5:39 am) thanks a lot for the info. I have another question in regards to my autoride adjustment. I have 35 inch Mud terrian on there and I would like to raise it another inch or so without the aftermarket lift kits. I know I can do it by adjusting the small rod on the sensor arm but when I look at it I don't see it twist or anything that shows me that it adjust? Can I fabricate a solid piece of steel and bend it and make it a inch or two longer and install it in place of the plastic rod and will that work to raise the yukon up some more? Help!
