Buick Century Oxygen Sensor

An integrant of Buick Century auto is the Oxygen Sensor which has the responsibility of measuring the amount of unburned oxygen in the exhaust to set the air-fuel mixture that the car engine requires for optimal functioning and environmental conservation. Depending on the produced voltage signal proportional to oxygen concentration, the sensor reports to the engine control computer as to the status of the mixture- is it which is rich or lean, and thus the fuel injector pulse width can be adjusted in real time. Through Buick Century car models, manufacturers use oxygen sensors made of zirconium dioxide, and they can be either narrow-band or wide-band. Narrow-band sensors supply alternating rich/lean signals whereas the wide-band ones supply wider signal range for better control of air-fuel mixture ratios. These sensors may deteriorate over the time because of contaminants and therefore contribute to high emission levels and even poor engine performance. Freshwater and constant checkups and repair of the Oxygen Sensor will enhance better fuel efficiency of Buick Century automobiles.
