I have a late 2016 MacBook Pro with touchbar, Model A1707. The battery was so bloated that I only had one spot I could push on the trackpad. I checked my serial number but the unit was not recalled for the battery so due to COVID and limited repair options I decided to swap it out myself. The exchange went well but when I started it backup I got the dreaded high speed fan and a root task sucking up all of the CPU. Did SMC & PRAM reset but still no luck. Ran diagnostics and it kicked out PFM006 & PPN001 errors. Hard to find a repair shop to even run full diagnostics. Any suggestions would be helpful.
MacBook Pro 15″,
macOS 10.13

Hi all, I have a 13 macbook pro 2015 and it served me well for years and there’s nothing wrong with it as far as I know. I never run the diagnosis and just run it out of curiosity. And it shows an error message «PPN001 there may be an issue with the power management system”
I tried to google it and and cant find what that means. Should I bring it to the genius bar? ( our of warranty)
Thanks

Have you looked into doing an online chat with an apple advisor to get more info on this?

Since your error message references «power management system”, I would recommend resetting the SMC:

High fanspeed and slow macbook. PFM006 & PPN001 Faultcode.
Hello! I have some trouble with a Macbook. It’s really slow and the fans are maxed out all the time. I downloaded Mac fans application and I can’t se the palm rest temp and I also did a hardware check (hold D when I start the computer) and I got two fault codes, PFM006 and PPN001. Is it the palm rest sensor or should I keep looking? I don’t want to replace things that I don’t have to replace.
Thanks!
Hi everyone,
all of a sudden yesterday my Macbook Air 13″ I5 started having loud fans and being a bit jittery.
This is what I did:
- reset PRAM and SNC
- cleaned system cache
- cleaned login elements
- rebooted in recovery mode and checked disk (HD was not mounted) >
- managed to mount HD and run repair, after that volumes looked all ok
- run diagnostics and then it gives pmf006 and ppn001 (plus ppt002 — low life battery) messages
No spillage has happened, nothing stranger than usual.
Logic board was changed by Apple in Dec. 2021
By running Acitvity Monitor the CPU load lies at max 60% (mainly kernel_task) and the temperature is 42/43°C…
macOs is Mojave 10.14.6
I am scratching my head. Anyone has some suggestions on what could be the issue here and how to fix it? I’d be extremely appreciative of any hint or tips!
Thanks a lot Dan…here are the screenshots from both apps
Any idea?
Thanks indeed…
Is this a good question?
