Reducing harmful emissions that come from your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your BMW 645Ci is heavily controlled by a computer which relies on input from the oxygen sensors. Your BMW 645Ci oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and it will likely be emitting an excess of hazardous exhaust.
