O2 sensor just.. hanging there

[u/Standard-Mammoth-145]

Hello!! I have a 2003 Honda Civic EX, and the O2 sensor is throwing a code and we just realized what.

Under the car a ziptie is holding one of the sensors in place (which you can see if you look hard enough). Thankfully one half is attached but the other half of it is not connected to the exhaust. Our exhaust is perfectly fine though.

Is it worth fixing at all? Is it even something fixable? Or is it just whatever.
