Default Voltage to MAF issue...

I am still dealing with MAF codes, consitently P0100 and P0103 codes. I tested the power coming into the MAF, one wire is 5.00-5.01, the pink primary voltage wire is supposed to be 12v, yet its only pusshing around 11.65-11.67 last I checked. This is my second MAF, is it possible the 11.65v is whats throwing the code?

Did you check the fuse? I had the same issue when i went through a puddle of water a few months back. It shorted off the o2's. But it is the same fuse.
Just a thought before you go buying another maf.

A fuse for the MAF? I guess I am unfamiliar with it. Where is located? The MAF is under a 1yr warranty, its a remanufactured one, so I can get it replaced. I just got this one like 1-2 months ago, and like 5 days after I got it, the code came back on again for MAF.

The fuse box under the hood. Look in the manual and it will be the sensors fuse. It's a 20A

I keep getting a P0100 code. Hmm, I may see if they can take it back, would be cool if they did. I'll try. The guy before me bought an OEM one, and it worked for about a week until the SES light was on. I replaced it, and a week later the SES light was back on. I guess I can shoot for the SLP one..

U may need to check the wiring to the maf also, go to a local shop and have them print u off a wiring schematic with all the right details(voltage, resistance etc) ull need a multimeter though to check! I wonder if u had a gm shop reflash ur computer if thatll help any!
