Apple AHT Error: 4SNS/1/C0000008: THSP— 124
My MacBook Air (mid-2012, A1465) recently started running very slow. Activity monitor show Kernel using >300% of CPU. Running the AHT consistently gives the following result:
Alert! Apple Hardware Test has detected an error:
4SNS/1/C0000008: THSP— 124
I have reset NVRAM/PRAM as well as SMC and done a clean reinstall of OSX. None of this made a difference.
From what I have found on Google, this error indicates a bad temperature sensor at the hard drive (SSD in this case).
I’m wondering if anyone knows where this sensor is located. Is it on the system board or on the SSD drive module. I’m hoping it’s on the SSD and that replacing it will also replace/fix the temp sensor.
Any advise on how to fix this problem would be very much appreciated.
