What happens when 02 sensor goes out?

What causes an oxygen sensor to fail?
O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a break in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).
How long do oxygen sensors last in cars?
