The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

Oxygen sensors measure exhaust oxygen. Their signals are used by the vehicle computer to adjust the air/fuel ratio and test vehicle emissions. Degraded oxygen sensors reduce engine performance and fuel efficiency, and increase harmful tailpipe emissions. They can also turn on the Check Engine Light and cause a car to fail an emissions test.
