Sensor Temperature not Working?
Seems my sensor temperature is not working.
Can I repair it?
When I turn on my MacBook Air the fan is running all the time. I made Apple recommended procedures for reset SMC and PRAM and no success.
I opened the case and the fan is running all time, since I turn it on. Checking the RPM for the fan in a software it appears as 0 RPM.
Thanks for any help.

Ok. I'm back after the tests!
1) Run the EFI test for the first time. FAILED the test:
Fan - Exaust (test 1) - Quick Motor Test
ERROR - Motor is spinning slower than it should.
- TEST FAILED -
2) Run the same EFI test again and than DON'T FAILED. It PASSED!
3) Run the OS test. Everything PASSED!
During all tests the FAN is running in a noise mode.

Is this a good question?
