Research on Oxygen Sensor for BMW 325Ci

It's important for the engine control module to be able to read the fuel mixture in the exhaust. That's what an oxygen sensor is there for. If this part fails, the air/fuel mixture in the engine will be off because the computer can't tell whether there is a rich or lean mixture entering the exhaust system. This can lead to more than just performance issues. Rich mixtures can damage the catalytic converter and other components. The O2 sensor is a small part, about the size and shape of a spark plug, that can be replaced without much hassle. A new sensor, however, will make a word of difference in how your car runs.

How Car Oxygen Sensors Work

Unless you need BMW E46 O2 sensor replacement, the unit will generate a voltage that corresponds to how much oxygen is present. Oxygen levels that are low mean there's more fuel that hasn't been burned in the combustion process. Higher O2 levels mean less fuel is present. The ideal mixture depends on air temperature, altitude, and various parameters related to engine load and performance. Once the signal reaches the computer, it reads the voltage level to respond by raising or lowering fuel injection as needed. Developed in the late 1960s, oxygen sensors have been used in cars since 1980.

Signs of a Bad Oxygen Sensor

The Check Engine light in your BMW 325Ci will likely come on if the oxygen sensor has failed or has started to. Other BMW 325i O2 sensors symptoms, like in your car, include reduced gas mileage, rough idling, and misfires. Output from the sensor is used to control combustion intervals, the air to fuel ratio, and overall engine timing. It's not unexpected that the part will wear out, given the environment it operates in. Oxygen sensors can last up to 90,000 miles in vehicles built within the last 15 years.

When Should I Change My Oxygen Sensor?

Sensors installed up to the mid-1990s should be replaced every 60,000 miles. Some newer units, especially those in OBD II-equipped vehicles, can go for 100,000 miles or more. The function of each O2 sensor should be analyzed during a routine inspection, not only when you first experience BMW E46 oxygen sensor symptoms.

BMW O2 Sensor Replacement Cost

If you have a 2006 BMW 325Ci, one front O2 sensor costs $331 to $429, and both will cost you up to $740 to replace. The two rear sensors come at the same price ranges. Parts are a major component of the charge but labor factors in too. Whether it is your 325Ci or BMW E90 oxygen sensor location in question, PartsGeek.com can help you save a bundle. Our overhead is low, so we make prices low. You can therefore avoid paying too much for replacement parts, by ordering deeply discounted products from our exclusive online catalog and secure shopping cart. Your ride will once again perform as new. Also, you won't have as much of a financial strain getting a new part that's really needed.
