Buick Regal Oxygen Sensor

Your Regal is a prized possession.

It's not a regular occurrence that you discover you need a replacement Oxygen Sensor to fix your car or truck. Buick car, truck, or SUV enthusiasts have come to expect a certain level of dependability when driving their Regal around town. Car aficionados appreciate the good looks built into each Buick, and understand that only the highest quality replacement Regal parts will suffice when repairs are needed. Make no mistake, you bought your Regal because you knew that you wanted efficiency and American style both impeccably combined into one car, truck, or SUV.

The function and purpose of Oxygen Sensor.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Buick Regal is heavily controlled by a computer which relies on input from the oxygen sensors. Your Buick Regal oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and emissions from your tailpipe may be in excess of legal levels.
