On a single exhaust there are two. One before the catalytic converter and one after it. You need special socket to remove them. O2 sensor have four wires. Two is for the heater. O2 sensor have heater inside them thats why they are called heated O2 sensors. The other two is for the actually leads that sense the amount of oxygen in the exhaust gas.
When the heating element in the O2 sensor is burnt out it would have a code related to the heater circuit malfunction. An old O2 sensor would have a code about slow response such as P0133 for example. Bad connection somewhere may indicate no activity.etc. O2 sensor are good for about 2 years then they start giving you problem.
