OEM Oxygen Sensors

Refine Results

Your car has an oxygen sensor that helps to measure the level of oxygen in the exhaust gases that leave your engine. The information is then used by your powertrain control module to help determine the amount of air and fuel ratio your engine needs at all times. The oxygen sensor is in your exhaust system and is crucial for your fuel injection and engine timing to work efficiently. A failing oxygen sensor can have a range of negative impacts, both for your engine performance as well as the environmental emissions that come out of your vehicle. It's important to pay attention to different signs that somthing might be wrong with your sensor so you can get a replacement as soon as possible. One of the first things that might happen is the check engine light coming on. Another thing that might happen is a decrease in fuel efficiency, because your fuel-delivery and combustion systems are going to be messed up as a result. Your vehicle running rough or misfiring, this can be from a failing oxygen sensor as well. When you determine you need a new oxygen sensor, be sure to get one that's made for your specific vehicle. We have a great selection here at OEM Online Parts.
