2012 Active Fuel Management (AFM)

[dave w]

I'm wondering how to correctly disable the AFM feature on a 2012 5.3 liter, or should I even attempt to disable AFM?

Is B0921 the only "switch" for this option?

I'm wondering if the Valve Lifter Oil Manifold is affected with / by AFM?

Thanks,

AFM is the cylinder deactivation via the lifters/oil solenoids if thats the question?

Ah, I see my question is a little vague. This is my first experience with AFM.

I want to disable AFM in the EFI Live programming. I'm wondering if B0921 is the only parameter needed to disable AFM?

Don't have any experience with that end of it, just have fixed a few of those trucks with lifter problems replacing cams lifters etc.

Yes, just set B0921 to No. That's it.
