What is an Oxygen Sensor?
An oxygen sensor senses the amount of oxygen in the exhaust gas and sends a signal to the engine computer (ECM), which adjusts the air / fuel mixture to the optimal level.
Too much oxygen in the exhaust gases indicates a lean mixture, which can cause performance problems, including misfire. Too little oxygen indicates a rich mixture, which wastes fuel and results in excess emissions. Either condition can shorten the life of the expensive catalytic converter.
Almost all petrol powered vehicles newer than 1986 have at least one oxygen sensor, and 1996 and newer vehicles often have two oxygen sensors.
Not only are properly functioning oxygen sensors good for the environment, but they can save money in fuel costs, too.
Replacing a worn-out oxygen sensor will do more than improve your vehicle's performance and reduce harmful exhaust emissions. It can save $100's a year in fuel costs.

When to replace and Oxygen Sensor
Exposure to carbon, soot, harmful gases, anti-freeze, chemicals, thermal and physical shock will shorten the life of an oxygen sensor. This results in increased fuel consumption, poor engine performance and excessive exhaust emissions.
That's why checking for, and replacing* a worn-out oxygen sensor is an important part of every routine tune up.

Engine Computer (ECM)
Based primarily on the oxygen sensor's signal, the ECM sends a signal to the fuel injectors.
Injector
Based on the ECM's signal, just the right amount of fuel is delivered to the combustion chamber, resulting in the optimal air / fuel mixture.
Oxygen Sensor
This oxygen sensor monitors the oxygen content of the vehicle's exhaust gases and sends a voltage signal to the ECM.
A post catalyst oxygen sensor is used on many newer vehicles to monitor the performance of the catalytic converter.
Catalytic Converter
Without the proper air / fuel mixture, the converter cannot eliminate harmful pollutants from the exhaust gases.

The World Leader in Oxygen Sensor Technology
Even though oxygen sensors have been standard equipment on most vehicles since 1986, most people don't know much about them. Bosch does.
Bosch is the inventor of the automotive oxygen sensor and the number one choice of car makers around the world. From the first unheated thimble type sensors to today's revolutionary heated planar and wide-band sensors, Bosch continues to lead the way in oxygen sensor technology and innovation. |
