Apple Hardware Test - Error Code PPF003

Hey there,

I bought a used MacBook Air 11’ 2013 (Intel Core i5 1,3 Ghz, 4 GB RAM, 128 GB SSD) off of eBay at the beginning of this year.

The seller had indicated that the Air runs slowly, which I thought I might be able to fix so I bit the bullet, since the asking price was 150€.

During the past months I noticed to particular issues:

  1. The fans of the air are constantly spinning. While the noise is audible it’s not comparable to the jet engine like sound seen and heard on other MacBook Airs in YouTube Videos.
  2. The Air runs extremely slowly in battery mode at times, with applications taking several times longer than usual to load or update information. This behavior does not appear, when the Air is plugged into power.

I ran several programs (EtreCheck, SMC Fan Control, Apple Hardware Test) and got the following results.

  • The Apple Hardware Test completes with the error PPF003 indicating that the fan is not working properly.
  • EtreCheck completes with the “Minor Issues”: High battery cycle count & Heavy I/O usage.
  • SMC Fan Control indicates, that the fan is not spinning (000 rpm).

I did a clean install of macOS Mojave 10.14.5, but the issue persists. Upon opening the case in order to clean the fan and renew the thermal paste I noticed, that the fan connector on the motherboard looks damaged.

I don’t believe this to be a software issue, since CPU usage doesn’t seem to be particularly high.

I’m happy for any input or further tests I could run.

Thanks in advance!

Peter

Well you’re fan connector was damaged by the previous owner or the person who last serviced the system. Your logic board will need repair someone with the proper skills should be able to replace it. Here’s an image on what the connector should look like

Vs your connector

The clamp latch is missing and it appears someone tried glueing it down which is not the correct fix.

Hey Dan,

thank you so much for your answer. The mechanical function of the fan connector doesn’t seem to be impaired, since I was able to remove and reattach the fan cable using the remainder of the clamp latch.

I will make sure to see how much having the connector on my logic board would run me. In case it gets too expensive, I will make sure to stay close to an outlet at all times, since this isn’t my primary machine.

Best,

Peter

The design is a clamp which applied presser onto the ribbon cable pressing it down onto the contacts. I don't see the left side so its likely only part of the connector is clamping.

This makes complete sense given that the fan still works, but no data is transmitted to the operating system.

Given that I have been quoted between 250€ and 495€ for the repair, this clamp will mist likely remain in this condition.

Thanks for your input.
