Incorrect air/fuel ratio, contaminates in fuel (water for example).

Any coolant will destroy O2 sensors.

And they do wear out.

Some newer cars use wideband O2 sensors, these give feedback to PCM much more quickly that standard sensors, they are, however, more exprensive.

Realize that just because you have a sensor error, does not mean the sensor is the cause, a contaminated MAF sensor, incorrect fuel pressure, cylinder misfires can also trigger O2 errors.
