Buick Rainier Oxygen Sensor

Why you drive your Rainier.

Buick car, truck, or SUV enthusiasts have grown accustomed to a certain level of reliability when driving their Rainier around town. It's not a regular occurrence that you realize that you have to buy a replacement Oxygen Sensor for your car or truck. Anyone who drives a Buick knows that when it comes to repairing their vehicle only the absolute best replacement parts will do. Obviously, you bought your Rainier because you knew that you wanted a variety of special features and fun both rolled up into one car, truck, or SUV.

The function and purpose of Oxygen Sensor.

Getting the most out of your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your Buick Rainier is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Buick Rainier 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 it will likely be emitting an excess of hazardous exhaust.

Good products, great prices, the best people.
