Buick Century oxygen sensors are responsible for transmitting vital information to the engine management computer. The oxygen is centered in the exhaust pipe and registers lean and rich mixtures. The computer takes in this information and then adjusts the fuel amount going into the engine. If the sensor is not working accurately, the computer has to guess. AutoZone has the right Buick Century oxygen sensor for your car, plus a team of helpful staff filled with trustworthy advice to answer any questions.
