Speaking of O2 sensor

I noticed my O2 sensor light on my dash of my 1993 Rodeo has been on for
sometime now, what does this sensor relate to and will I notice any change
by getting this changed out....off topic is this a fix I can doing on my
own? expensive?

Thanks for your time.

Cheers!

I don't know about the Rodeo, but my parent's 93 Trooper has an O2 light.
It dutifully turns on every 90k miles. Not sure if the Rodeo has the same
instrument cluster and method of turning it off (assuming it's even turning
on for that reason), here's how I turned off their 93 Trooper's light.
