The BMW 330xi Oxygen Sensor is an essential part primarily recognized for its dependability and functionality in enhancing the proportion of air to fuel for greatest performance. Specifically, this sensor determines the amount of oxygen in the exhaust and sends information to the engine control computer to change the fuel injector pulse width. Thus, the BMW 330xi Oxygen Sensor in making the vehicle closed loop system its function enhances the operation of the catalytic converter while at the same time reducing toxic emissions. Every BMW 330xi has at least dual oxygen sensors which are upstream and downstream, so as to enable observation of the air-fuel mixture and condition of the catalytic converter at the right time. The upstream sensor detects the richness or the leanness of the mixture while the downstream sensor checks on the working efficiency of the catalytic converter. The function of the BMW 330xi Oxygen Sensor should also be checked for faults frequently since a faulty oxygen sensor results in high emission and low fuel economy. Further, the construction of the sensor is usually made of zirconia, which is coated with platinum in most instances to increase the life of the sensor as well as its reliability. The BMW 330xi manufactured between 2001 and 2006 exhibits oily sheen, a larger inline six-cylinder engine and, more importantly, all-wheel drive. The BMW 330xi has a engine capability of 247 km/h with excellent driving comfort; thus, it is competitive in the automotive market, and having a Oxygen Sensor equipment is significant to its performance and safety.
