A small vehicle component that makes a big impact, oxygen sensors control or contribute to several vital engine functions including fuel/air mixture, timing and emissions. Known to fail anywhere between 30,000 and 100,000 miles, it's always a good idea to have a replacement O2 sensor on hand for when the time comes. Replacing a faulty oxygen sensor is an easy, DIY job that can ensure peak performance, along with savings at the pump, in just a matter of minutes.

In this day and age, it's increasingly important to be responsible about the amount of emissions your vehicle produces. By feeding data to the engine control unit (ECU), your vehicle's oxygen sensor helps your engine run as efficiently as possible, while producing as few emissions as possible. If one or more of your ride's O2 sensors is not functioning properly, not only will you fail any emissions tests, but you're throwing gas money out the window and possibly causing damage to your catalytic convertor.
