The oxygen sensor is a device which determines the oxygen content of the exhaust gas. Since the amount of oxygen in the exhaust gas is a very good indicator of combustion efficiency, it is also the best place to monitor the air fuel ratio.

Located in the exhaust system, the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air.

Oxygen sensors can fail when the sensor’s ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine adds to the sensor becoming oil-fouled. Small amounts of tetra-ethyl lead in the petrol or over-the-counter fuel additives, which are not “oxygen sensor safe”, can also kill an oxygen sensor.

The oxygen sensor is manufactured in Japan to a very high standard by NTK. NTK is part of NGK Spark Plug company, which was founded in Japan in the 1930's and NTK has been around since the late 50's.
