In the old days, gas was cheap and plentiful, with no end in sight. Back then, we didn't think too much about where the stuff coming out of our tailpipes was going - we just figured the wind would blow it away. Well, we've learned a thing or two since then, and gasoline is now hovering around $3 a gallon.

In response, cars now have a number of high-tech devices designed to reduce emissions and decrease fuel consumption. The Chevy Trailblazer Oxygen Sensor is one such device, working with your catalytic converter and fuel injection systems so as to make the best use of that precious fuel, burning it more completely and more cleanly than ever before.

As you know, the engine requires both air - specifically, oxygen - and fuel in order to run. When this mixture contains more air, the engine uses less fuel. Less air means more power, but greater fuel consumption. By measuring the amount of oxygen in the exhaust gases, the Chevy Trailblazer Oxygen Sensor determines the optimum ratio of air to fuel for given driving conditions. It sends an electronic signal to the injectors, which makes adjustments to the mixture - making it richer or leaner, depending on engine load and and speed. When an oxygen sensor is damaged or defective, engine horsepower will decrease, and both fuel consumption and emissions will increase. If you notice this happening to your vehicle, a new Chevy Trailblazer Oxygen Sensor may be the solution. We offer the lowest prices on a complete line of parts and accessories for your Trailblazer, as well as almost anything else on four wheels.Log on to our website and order yours today!
