Oxygen sensors hold a chemical reaction that produces a certain voltage. Your Buick's engine computer notes the voltage and determines if the mixture is rich or lean, adjusting the amount of fuel sent to the engine accordingly. If your Buick LeSabre oxygen sensor is not working, the computer has to guess the air/fuel ratio instead of relying on data. This results in performance issues and excessive fuel consumption. Check out AutoZone's selection of LeSabre oxygen sensors today and get your ride back on the road.
