820-3332 th1H sensor error

[macfix]

Hello everybody;

Working on this machine come service with fan noise and %400 kernel task use problem. ASD OS not shows error, ASD EFI shows Th1H sensor is reading above the high limit

Checked and replaced, Q5501,Q5503,U5550 nothing change.

Where can i check next step?

Note: not liquid sign machine.

Did you let ASD continue on error? If TH1H is reading off and it is not Q5503 then TH2H should give an error too.

When run ASD first time after parts replace ASD nothing show error but fan spins high dukefawks . Run second time ASD give same error but third time no error

Note: Fan noise and kernel task starts 2-3 min later after machine power on.

Is C5552 on the board, I think it is no stuff but replace if present. Check traces to Q5501/03.
