06 LBZ MAF issue

[tanman_2006]

I am getting p0101 mass/volume air flow circuit error.

Will a simple cleaning work?

My truck bellows black smoke now, I assume this is the cause

I'd go get MAF cleaner and do that right away. You are still running the stock intake aren't you? If it's an oiled K&N or similar then that's why your MAF is coding.

Stock intake with Donaldson power core.

 

[tanman_2006]

Its filter and fluid change day anyways, a little maf cleaning won't hurt.

 

[btfarm]

Good luck! Let us know. At least you have the right filter setup but with the dirt you experience I'm not surprised you could have some trouble.

 

[tanman_2006]

First problem w/ 268k on the clock. Not bad IMO.

PO had knn drop in, I dropped it out and sold both his filters. Used the $ to buy 3 power cores lol.

They say 100k mile filter life on them, I replace every 25k.

 

[btfarm]

Yeah, I get close to 100k air filter life and I probably would be fine going further.

 

[tanman_2006]

Ashamed to say I found the problem...

Must have missed a filter change... Oops

 

[btfarm]

WOW!

 

[tanman_2006]

I show in my book I put a wix filter in last fall. That was 18k miles, looks like I will keep a better stock of power cores

 

[tanman_2006]

New power core installed, ordered 2 more, cleaned maf, and all is well.

Dissected the filter and it had some how gotten wet (been raining a lot lately) and had a decent amount of rye pollen loaded in it.

Last week I got my swather stuck in a rye field and tried to yank it out with my truck, at the same time I had to drive through about 12-18" deep standing water to get a good angle on the swather, I think the moisture caused the glue to loosen then the heavy loading of pollen caused it to fail. Never had that with a power core, that's normal wear and tear for my truck.

You DO work it hard Tanner...

 

[tanman_2006]

Only on days that end in Y

 

[btfarm]

Ok that explains it...

Needing an air filter falls under pm not repair class, so idk if your allowed to call this its first real problem yet. If you do, I think it gets an asterisk next to it in the book.

 

[tanman_2006]

The maf worked after I swapped the filter. I cleaned it just because I was there and had the stuff ready for it.

Nice. Two questions. Did you have the white or the blue filter media for the Donaldson Power Core filters? The blue filter media are the better ones with higher mileage ratings. The white filter media are good, but you must change them yearly.
2nd. Where did you order them from and about how much do they go for?

 

[btfarm]

I think the blue ones were discontinued several years ago Jeff. They were part number AC3087 IIRC. The replacement is #29-- something

 

[RI Chevy Silveradoman]

Yup. They were. I had purchased 3 of them before they discontinued them. I believe you csn still get the blue through Amsoil.

 

[tanman_2006]

I purchase through amsoil (perfered customer) and my power cores are always white. My cost was ~67

I do change them yearly but the wix must not be near the same quality. The power cores have an X in the back to catch a separated filter.
