What Oxygen Sensor does for your vehicle.

Getting the most out of your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your BMW 323i is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your BMW 323i oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.
