Service Throttle Body. Sigh. P00AF code

[c3k]

Ok, it happened. Driving up a mountain pass (Fancy Gap, I-77, VA/NC border), at speed, I got some error messages and a check engine light. "Service Electronic Throttle Body" and "Service Electronic Stability Control". Both associated lights illuminated as did the MIL/CEL.

Truck drove, but with an obvious lack of oomph. No turbo.

About 30 minutes later, I pulled over and checked it with my scan tool. P00AF Turbocharger Boost Control Module 'A' Performance

So, I did what any truck owner would do. I shut down, cleared the codes, disconnected the battery, jumped the positive and negative battery leads together for about 10 seconds, then hooked it all back up.

I drove (hard) for 3 hours (with two stops). No more CEL/MIL. No codes.

I'm hoping that it's my 4+ year old battery causing a momentary electronic glitch. Mitigating against that was that it occurred after an hour+ of highway driving, so the battery had had a long time to charge.

Any thoughts?

(Edited to add: on another forum, there's a big thread on this code. It seems to lead to a turbo replacement.)

Following. Fingers crossed you don’t need a turbo. How many miles are you at now c3k? Just cracked 102,000 myself.

Actually now that I’m thinking I did get a “service throttle body” message after a few long cranking periods killed my battery up in the frozen north. Had my fuel freeze up earlier this year on a ski trip. I do not recall the P00AF code being in there though.
