There are four O2 sensors on a 1998 Honda Passport, so when you have it put on a computer and it shows up "O2 Sensor" make sure to get more info such as Right bank, Left bank, etc, or it will be just a shot in the dark which one is bad. They are pretty easy to find just follow your exhaust system out from the engine.
The code means there is no activity on bank one sensor three. So sensor three is either disconnected or not working.
