When should I change my o2 sensor?
I have a 02 Civic with over 110k on and seems like my mpg is just not what
it was even after new plugs, filter, so thinking possible it's time for a
new o2 sensor but my manual does not say as far as I can find when it time
to change out. Any body no for sure when it's needed? Thanks, Rob.

The O2 sensors are generally not on a schedule these days. They are
normally changed when indicated by a check engine light & code readout
or when increased exhaust emissions indicate that the sensor might be
getting slow to respond.
That said, treating it as a maintenance item at 100k miles isn't a bad
idea. You are concerned about the first sensor before the catalytic
converter, not the second one after the converter.
If you do change it, stay away from the "universal" type which is
spliced into the line. You really want to use one with a correct set of
wiring and connector. Denso would be my choice on a Honda.
rockauto.com and others generally have them.

------------------------------------
O2 sensors need to be scoped to be sure if they are 'tired'. OBD II
doesn't care too much if they are lively, so long as they still cycle.
Don't forget to do the PCV as well. It often gets overlooked, and it can
lead to the demise of your CAT if it allows too much oil vapor to be
sucked out of the engine.

Re: When should I change my o2 sensor?
As the others said, there is no time/mileage spec on the O2
sensor. It is early for yours to be working poorly. I'd do
basic tuneup items first and then see how your car performs
for a month.
Heed to the letter the gas mileage tips for Hondas given at
the site below, and your mileage could improve
significantly:

Re: When should I change my o2 sensor?
It is a shame you are spouting bad information about OBDII. OBDII systems
monitor rise and fall time of the O2 sensor as well as voltage levels and
current levels. If any aspect of the O2 sensor goes bad the computer will
tell you. The original poster here apparently has no idea of how to
determine gas mileage. He needs to measure the mileage as well as consider
his driving habits and the type of fuel he is using. Fuel formulas change
this time of year which will cause lower mileage as alcohol is added. You
can start throwing parts at a perceived problem but you are wasting your
money...
