Fan speed and keyboard problems

Hi there.

I'm Patric and just joined the community because I'm looking for help. I have a massiv problem with my MacBook Pro Unibody 13" 2x2,26GHz Mid 2009 10.6.8.

Important Information before I will come to my current problem:

1 year ago I spilled a beer into the keyboard od my MBP. I disassembled the hole MBP,cleand it inside, let the parts got dry and put it together. Everyting except the keyboard backlight worked fine again.

Now, one year later suddenly my fan is out of control. When I turn the MBP on, the Fan speeds up to 6200rpm synchron. Kernel_task uses 90% of the CPU. In Safe Boot the fan is also at 6200rpm but the kernel_task keeps clam and it's possible to work.

Apple Hardware Test:

Problem 4SNS/40000000:TsOP-128.000

I think it's the temp sensor.

I tried to find out if there are possibilities to fix it but I can't find any informations. Maybe one of you guyes can help me?

-I changed the HDD, RAM, Display - no improvement

-Fresh install 10.6 - no improvement

-Fresh install 10.7 - no improvement

-SMC & PRAM and NVRAM - no improvement

-Tried smcFanControl, iStat Menues 3 and Fan Control but none of these apps cloud change the fan speed

A few minutes ago I recognized that the keyboard doesn't work at all. CMD (left) turns alternating on/off. Shift (left) seems to be broken.

Is it possible that the keyboard ribbon cable causes problems like this?

I'm very grateful for your help and please excuse my bad English.

First hook up an external keyboard and mouse to isolate the problem. If this solves the problem you may be able to replace the uppercase cables, if not replace the upper case.

Looks like this may be your machine:
