Chevrolet Trailblazer EXT Oxygen Sensor

Why you drive your Trailblazer EXT.

Anyone who operates a Chevrolet knows that when it comes to repairing their automobile only the most superior replacement parts will do. You bought your Trailblazer EXT because its reliability and value appealed to your senses; so why would you settle for anything but the best when it comes to superior quality auto parts? Your Chevrolet dealership isn't the only place to find trusted repair parts to fix your Trailblazer EXT. Obviously, you bought your Trailblazer EXT because you understood you would be getting performance and American style both rolled up into one vehicle.

The function and purpose of Oxygen Sensor.

Getting the most out of your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Chevrolet Trailblazer EXT is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Chevrolet Trailblazer EXT 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.

You've tried the rest, now try the best.
