MacBook Air 13 early 2015 820-00165 is slow

[Cocobill]

Hello everyone,

I got this Mac and it is on the slow side. Internet diagnostic feature shows error codes PFM006 and PPN001. Board looks clean. I replaced I/O board, nothing changed.

Any ideas?

Check which sensor is failing. I will send you a DM

Running the MRI test shows yellow exclamation mark at "Apple Diagnostics", red exclamation marks at "Battery", "Fan" and "Sensors" and it hangs at the phase "Testing sensors" ...

You running the 64 bit version?

 

[Cocobill]

Yes, I ran MRI 64bit...

Let it sit and see if it finishes. I have not seen MRI hang like that yet. Once it finishes you should be able to click the tiles with battery/sensor/fan etc. and it will show which sensor exactly is failing.
