How long can you drive a Honda Civic 1998 with a bad sensor? I know you should get it repaired as soon as possible but how long can you drive it before it causes anymore damage?

It's hard to say how long you can drive with a bad O2 sensor. Driving for any prolonged period of time has some detrimental effect on the catalytic converter. An O2 sensor that gets lazy is one thing it doesn't properly track and trim fuel mixtures resulting a variance to fuel consumption and emission out put. A sensor that is failed all together can allow an engine to run extremely rich or lean, a failed heater circuit may be a lesser of the evil scenarios, the heater circuit gets the O2 Sensor up to operating temperate quicker and maintains it there when certain engine running criteria is not met.
