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?
Is this a good question?

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.

Are you sure of the error code? Could it have been VDC003?
