OEM:BOS-01

An oxygen sensor like the Buick oxygen sensor is an electronic device that measures the proportion of oxygen in the gas or of the liquid being analyzed. A gasoline engine cannot burn gasoline without oxygen, and a certain ratio of air and gasoline should be maintained. If the air is less than the perfect ratio which 14.7 of air is to 1 gasoline, then there would be a fuel left over after combustion resulting to pollution, and this is called a rich mixture. A lean mixture on the other hand, happens when there is an oxygen excess resulting to additional production of nitrogen-oxide pollutants and might lead to poor performance and even engine damage.

Moreover, oxygen sensors are usually located in the exhaust manifold or exhaust pipe to strategically detect the richness or leanness of the air and gasoline mixture going into the engine. Upon knowing the score, the information is then sent to the electronic control unit computer for make the proper adjustments of the mixture thus giving the engine the best possible fuel economy and lowest possible exhaust emissions. It is highly advised that you constantly keep on eye on your oxygen sensor to prevent damage of your car's catalytic converter and other expensive repairs.
