#1 MacBook Air M3, A3113, EMC 8611, Mobo 661-40169, Keyboard Connection Board Problem

Hello Everyone,
There was a liquid damage what was cleaned but 3 pins still measure low resistance to ground.
I have removed connector to clean the board area but problem was the same.
I am looking for help to identify which chip is causing low resistance to ground.
There is no schematic for the small board and I can't verify where connections are going to.
Can someone please point me to correct chip/IC linked to problematic connector for lid angle sensor ?
Thank you in advance.
Regards,
Rafal
