When the computer lights the MIL and the code says they no longer work properly or when they are suspected or confirmed to not be working properly. They aren't a replace just-because-they-are-old part like a belt or hose.

After getting codes concerning one of my 02 sensors at 150,000 miles (96 3.8 mustang coupe) I changed all 4 of mine while doing it.. Seemed to be more responsive afterwards.. Chuck (in SC)
When they fail!
I have an 89 with 100K miles and one of the two are stock. The only reason I replaced the other one is I crushed the crap out of it trying to get it out of the OEM H pipe when I put my new exhaust on.
