Hello, For several days I have a problem with the MacBook Pro (Model A1278 Mid 2012), I ran Apple Hardware Test and I reported the error: 4SNS/1/C0000008: TAOP - 124. After the error code I think is ambient temperature air temperature sensor. Where is this sensor located and if it can be replaced or disabled. TA0P Temperature Ambient air Temperature sensor Now I have it installed on Windows 8 software that shrinks and spins the fan. In Mac OS X that I can not use you kernel_task processor to 300% because of that sensor. I replaced the trackpad but nothing was solved, so the sensor is somewhere else .. people at Apple think they have replaced the motherboard but not related to my problem. Thank you.
