The oxygen sensors fitted into the exhaust system of your BMW 840Ci serve two different functions, depending on their placement, both of which are important to your car's performance. Upstream, or front sensors are located in the area between the car's engine and the catalytic converter. These sensors monitor the oxygen content of the exhaust gases as they are leaving the engine. This information is used by the engine control computer to regulate the air/fuel mixture as well as other operations.

Downstream, or rear sensors are fitted into the exhaust system after the cat converter. They monitor the O2 content of the exhaust after is has passed through the converter. This information is used to determine the effectiveness of the catalytic converter. Faulty oxygen sensors should be replaced with a new, quality unit, such as those available at PartsGeek.com. Model years covered for the BMW 840Ci include 1994-1997.


They are available for the following BMW 840Ci years: 1997, 1996, 1995, 1994, 97, 96, 95, 94. This part is also sometimes called BMW 840Ci O2 Sensor.

I'm very impressed with the quick delivery, even with “ground” delivery. It took less then 48 hours from the time the order was placed. And it’s a better quality brake drum then any auto parts store can get, they all get China crap that dose not work. Plus your cheaper the any of my commercial accounts can offer. If you can deliver like this all the time, you are now my main source for brake parts. Thank you very much. Chris
