Honda Repair: oxygen sensor, honda passport, oxygen sensor

Question
I have a 95 Honda Passport 4cyl 5spd and  my O2 light came on. Does this mean I have to replace my o2 sensor?

Answer
andre' yes this can be the first indicator of one of them going bad. You have one on the front of the engine near the manifold cover, the other one is located under the car near the catalytic converter. You may have the change both because if you change one, the light still may come on.
