323 E36 O2 Sensor

Your BMW 323i oxygen sensor is designed to do a very critical job on your car’s exhaust system. Together with the catalytic converter, the oxygen sensor is a must to control exhaust pollutant emissions. It is the job of the oxygen sensor to regulate the air/fuel mixture by calculating the amount of oxygen present in the exhaust gas. When the fuel/air mixture is exact, your BMW 323i will function efficiently. And a fairly-lean mixture can produce the lowest emissions. This is how your BMW 323i oxygen sensor works.

The oxygen sensor perceives the lean/rich condition of the air/fuel mixture then quickly sends out an alert to the vehicle’s engine management computer. This engine management computer in turn delivers an order to the mixture control solenoid located in the carburetor to fix the mixture before it goes into the engine. To operate correctly, a high temperature is often needed by the oxygen sensor.

Problems can crop up with the oxygen sensor when it can no longer send out accurate data. Some oil additives, silicone, and condensed water can taint the oxygen sensor’s probe tip, and with the probe tip contaminated, it cannot exactly measure the quantity of oxygen in the exhaust gas. This will result into faulty and delayed air/fuel mixture readings, reduced fuel economy, stalling, and amplified tailpipe emissions.

Malfunctioning oxygen sensors can also cause early damage to the catalytic converter. This is where replacement oxygen sensors come into play. Signs of damage taken well will further halt imminent damage to all parts related to the oxygen sensor. Get your new BMW 323i oxygen sensor here.
