Check the resistance between ADC_3V3 and ground, also from ADC_3V3 and the positive end of C106.
ADC_3V3 and ground - Starts around 12K and increases to about 20k while leads are held on contacts
ADC_3V3 and the positive end of C106 - about 12K

Measurements on the board of R110 and R112:
R110 - 12K
R112 - Increases from about 12K to about 20K while measuring
