Apple hardware test brings error 4SNS/1/1C0000008:TN1D--124
my macbook had suffered a waterspill and some components had to be replaced 4 months ago. The battery wont work even if i changed it. The microphone was replaced to no sucess. The dc in board was replaced and works fine . A memory module died but i havent bought a new one yet.
So It runed smoothly after repair until almost a month ago . The fan starts to spin to full speed and the shell process taks all cpu load and system slows down tremendously.
I run Apple hardware test on startup and got the error:4SNS/1/1C
So i means a sensor is failling but which one is it?
Istat pro brings all temperatures to normal temp , in between 30 and 38 celsius.
I am using the laptop now on safemode and runs normal but video is not working for video playback and audio neither.
How can i detect if another sensor is wrong? CAn someone decode the above error message and tell me which sensor is wrong? I dont have apple care and cannot ask an apple certified repair shop. I live in north mexico and there is no oficial apple shops up here in Ensenada Baja California!
Help me ! Thank you!

This error code seems to be the logicboard from the research i have done on it, and yes, they spilt liquid too, however it could be a sensor
I would say it is the logicboard or a sensor from my research, but i will give you a few things to try
Reset the PRAM by pressing command, option, P and R together before the bong and it will reset the PRAM, the computer will restart so let go after the second bong
Reset the SMC controller using the instrucins from this apple support article
If this fails, it may very well be your logicboard or a sensor somewhere
by the way the system slows down because the CPU load becomes 99% although there is no particular process shown on activity monitor that takes all the cpu time. Only activity monitor seems to take 10% and only 30 megabytes of RAM. So its not a software issue !
