A new Radix install (purchased LoudAzzLowStepside's kit) on a 2006 Flex-Fuel 5.3 Suburban is pulling a MAF curcuit signal low code (check engine light is on)? The instructions say to splice into the MAF wiring (the black and tan wires), which I did. There is also a black with white stripe wire, did I use the wrong black wire? Magnusson told me Black and Tan today, but couldn't help with the code? Used Bryan @PCMsforLess tuning, and runs good and pulls hard otherwise.
Any help would be appreiciated. Thanks!

 

what is the actual code? If you have a signal low code, more than likely you have the wrong ground cut.....Please post up a picture of the MAF plug and the wires you cut.

 

P0102 is the code. I am splicing into Black and Tan as instructions stated.
But kit was from a 2004 as you know, so does the 2006 have a different ground? maybe the Black with white stripe wire? Can I hurt anything by trying it? Can that sensor with two white wires (that I'm splicing into) be bad and be popping the code? I will try and post some pics later. Thanks

 

there are two grounds in that MAF, one for the IAT and one for the air meter. I suspect that you have cut the ground for the air meter since you do not have a IAT sensor code.
