Heat Sensor Problem 4SNS...Th0H
For some time my MacBook Pro has been running slow and the fan runs constantly. The closest Apple store is 3 hours away and I haven't had the ability to surrender my laptop for more than a day so I've just been living with it.
I ran the Apple Hardware Test today and it gave me the following code:
4SNS/1/40000000: Th0H - 78.250
As best I can figure, this points to a heat sensor but I can't tell if its something I could fix on my own or if I'm at the mercy of the unavailable and expensive Apple Store. The only repair guys within a reasonable distance have a horrible reputation so I've done everything myself up til now. I think this may be above me, however. Is it?
Help? Anyone? TIA!
Es esta una buena pregunta?

try to download "iStat" and see what it tells you on the heatsink side.

Thank you, oldturkey03. I downloaded iState (very cool, thank you!) and captured two readings several minutes apart, after resetting PRAM and SMC. As follows:
HD 42/42
CPU 94/70
Airport Card 51/48
Enclosure Base 26/26
GPU Diode 91/84
GPU Heatsink 71/66
Heatsink A 69/65
Heatsink B 47/46
Right Fan 4292/4360
Left Fan 4292/4364
I have no idea what these numbers mean, though! Any help interpreting them would be super appreciated! TIA!
