[SOLVED]820-3437-B Liquid damage, unable to read sensor error

[appleonarim]

Hi

Board was repaired 2 months ago ( liquid damaged a lot of place, ultrasonic cleaned and reballed SMC every thing was ok) but computer came back with fan noise and too slow. ASD report an error like bottom,

SMC: 0x0 (test #1) - SMC Critical Sensor Check Test
- Checks if the SMC reports any errors on critical sensors.
[16:06:36] ERROR -- 1 [The SMC reports an error on one or more critical sensors.] -- TEST FAILED

Temperature (Th1H) -- Fin Stack (test #1) - Sensor Reads Within Operating Range
- Check to ensure that sensor reads within operating range.
[16:06:54] ERROR -- 1 [Unable to read sensor] -- TEST FAILED

Temperature (Th1H) -- Fin Stack (test #11) - Extended Sensor Flat Line Test
- Checks that the Sensor changes value i.e. not stuck, with longer time allowance for change (5 mins).
[16:07:34] ERROR - -13005 [The SMC can not read this sensor] -- TEST FAILED


Replaced SMC nothing changed.

Any idea for start to check?

This sensor is on the IO board. Check cable/connector or replace IO board.
