Ts0P = Trackpad flex cable

I think you have to look a bit deeper here. I suspect something was spilled into the keyboard/trackpad causing it to error out here. If you're sure the sensor is gone you'll need to replace the trackpad flex cable.

I would also install a good temperature monitor app like: Temperature Gauge Pro to better monitor the sensors.

I had the same problem and I got a replacement ribbon flex cable (connecting the trackpad to the logic board). The problem is solved. Thanks a lot.

I have the same error code;

Symptoms;

Fan runs at max speed all the time,

In normal boot, kernel_task is taking over 100% CPU

In safe boot , problem is gone.

If ioplatformplugins kext/ahci SMC profile for MBP 8,1 is removed (the model of my crapbook) the computer runs normal, but the fans are at max speed.

I need location of sensor (palm sensor) which I believe is under trackpad, because I refuse to pay crApple $600 to herp the derp.

Thanks guys!!

You'll need to follow this guide: MacBook Pro 15" Unibody Late 2011 Trackpad Replacement as we don't have one explicitly for the 17" model.
