iPhone 8 failed continuity testing!?

Hello, I am trying to refurbish an iPhone 8 and during continuity testing on the Soundboard Port (Circled in red) I received these readings as apposed to the usual “001”:

It averaged 1944 ohms when the red wire is north on the port, however it averaged 552 ohms when the red wire was south on the port

I have tested the Battery, Screen and everything else and it all seems to be fine apart from this one port.

Has anyone had the same issue or just give advice as to what the issue could be and what steps I could take to repair the problem?

Thank you all in advance
