Did you check for continuity in both directions i.e. between 1 & 2 and 2 & 1, 1 & 3 and 3 &1 and 2 & 3 and 3 & 2?
Just asking as there are two diodes in the component so they will conduct in one direction but not the other depending on which way the meter leads were placed.
Also there may be no continuity from pin 1 back to the charge port as there is another diode in the path i.e. PQ2. Again it depends on which way the meter was connected and also if your motherboard is the same as linked above ;-)

I think that it is used to guard against transient voltages from the port being passed through to the motherboard's chipset when the charger is plugged in but this is only a guess as I'm no expert.

If it is faulty it is best to replace it as it's put there for a purpose. Manufacturers don't spend more than they have to when designing/making electronic devices
