4 Signs Your Oxygen Sensor Is Bad

Cody Wade

You expect your vehicle to get you where you need to go. However, you have to put the time and effort into making sure your ride is properly maintained at all times. When you notice your vehicle acting funny, you need to get it into the repair shop to determine what is going on with it and how to correct the problem. To help you identify some of the common symptoms of a bad oxygen sensor, continue reading below:

Gas Mileage Starts To Decline

Your oxygen sensor plays a pivotal role in adjusting the amount of air your vehicle gets in relation to the fuel. It combines air and gas to give your vehicle the power it needs. Faulty O2 sensors can end up allowing too much fuel into your system, thus causing your gas mileage to suffer. The more fuel it pushes through your system, the less you will have for your normal vehicle operations.

Vehicle Emissions Increase

The oxygen sensor helps to adjust and monitor the mixture of fuel to air, ensuring that your vehicle is getting the right amount of engine combustion, performance and vehicle emissions. When the sensor starts to go bad, it causes the fuel to air mixture to start running lean. This can cause inefficient engine combustion, ultimately causing your vehicle emissions to soar. Depending on where you live, bad emissions can earn you a fine, or  you may have trouble passing the smog test.

Engine Is Idling Rough

Your vehicle needs the right amount of engine combustion to deliver the engine performance it needs. Bad sensors can end up causing your engine to sound rough and chopping when trying to idle. This is often the direct result of poor engine combustion firings, resulting in horrible engine performance.

Engine Keeps Missing

When the sensor is bad, it causes your air to fuel mixture to either run lean or become completely restricted. All of the explosions in your engine's cylinders are going to end up being altered. Once the mixture becomes too lean, it causes your engine to miss, especially if you are sitting somewhere and letting the vehicle idle. This could also cause your vehicle to stall out on you when driving down the road or sitting at a stoplight, making it quite dangerous for you to be on the roadways.

If any of the above sounds like something you are dealing with, it might be time to have your oxygen sensor tested for potential problems. You can talk to a place like Blue Valley Garage for more information.

Learning All About Auto Body Restoration

Hi guys, the name is Phyllis. I'm here to teach you all there is to know about auto body repair. I grew up watching my dad strip down cars and restore them to new with beautiful coats of paint. Between coats, I loved to see how the sanding process removed imperfections and readied the surface for more paint. I grew to love the hobby enough to try it out for myself. My journey started with bicycle frames. The frames easily hung from the ceiling to make sanding and painting a breeze. Eventually, I took my sander and sprayer to the finish of my old car to restore its beauty. You can learn about the auto body repair and restoration process by visiting my site each week. I'll share information about traditional and modern techniques, tools and parts you can use to improve the finish on any vehicle. Thanks for visiting!
