Oxygen Sensors: What Are They And Why Does Your Car Need One?

A typical vehicle requires car repair and maintenance services regularly. Maintenance services focus mostly on preventative car issues, while repairs fix broken things. For example, one thing that might break on your car is its oxygen sensor, also called an O2 sensor.

You might not know what this part is or why you need it, but you should know that it's a vital component found in most vehicles. You can learn more about this vital part by reading this guide.

What is an O2 sensor?

An O2 sensor is a vital part of your engine. This sensor controls the amount of oxygen that the exhaust puts into the fuel the car burns while operating. As a result, it assists with your fuel usage and engine performance. Additionally, it controls your car's emissions. If your county requires emission testing, you might have trouble passing the test if you have a bad O2 sensor.

How do you know if yours is bad?

The primary way that car owners know they have bad O2 sensors is through the "check engine" lights that illuminate. Most cars come with "check engine" lights, and they serve a vital role. This light turns on in a vehicle when it senses an engine problem. When your light comes on, you might not know what problem your engine has, but you'll know there is a problem. You can find out it's the O2 sensor by allowing a mechanic to run diagnostics on your vehicle.

Another sign that your O2 sensor is bad is if your car starts using more fuel. For example, if you suddenly experience a significant decrease in your gas mileage, it could be a sign that your O2 sensor isn't functioning properly.

What happens when your O2 sensor stops working?

Your car will still operate if you have a bad O2 sensor, but leaving a bad one in your engine can lead to issues. Your engine might wear out faster, and you'll use more fuel. You might also have negative impacts on your exhaust system.

Hire a mechanic to fix your car when you need repairs
