Chosen Solution
Hello, my computer has been acting very sluggish and the fan is always running at full speed. I just did an Apple hardware test, which came up with this error code: 4SNS/1/40000000: VCOC-3.202 Can anyone tell me what this means, and what I need to do about it?
That error would indicate some sort of issue with the CPU Voltage Sensor. Was there any kind of liquid damage? The mostly likely solution is going to be a logic board repair, your CPU/related components are damaged.
