Bad Oxygen Sensor Symptoms

Shamaley GMC can show you what bad oxygen sensor symptoms are.

With all the different sensors your car uses daily, perhaps one of the more vital sensors is the O2 sensor, which is required for a vehicle to drive at its top-notch capability. Because of all of the exhaust fumes any vehicle creates, it’s important to have a piece of tech that recognizes the oxygen levels in the exhaust gases. The sensor has a crucial part to play in keeping track of a vehicle’s O2 amount to make sure the engine is correctly using its gasoline. A good-working oxygen sensor will be an essential cog for a consistent running vehicle. Still, a bad oxygen sensor can most likely lead to bad gas economy, a horrible odor in your vehicle, and affect your engine’s performance capability. Here you’ll learn about things to watch for when using your car that could be easy-to-see signs of a poorly-working oxygen sensor.



The Issues A Failed Oxygen Sensor Can Cause

What Are The Problems A Bad O2 Sensor Can Cause?

If you’re driving on the road and smell something harsh from your vehicle, this could be a crucial sign that your oxygen sensor is going bad. If you ever begin to keep track of any negative differences like bad powertrain performance, loud noises, or misfires, that can be a clear result of your oxygen sensor probably having issues. A severe issue a failing oxygen sensor might happen is an unexpected catalytic converter failure, which will likely cost you a lot of money to replace and may put your car in the shop for a long duration of time.

How Does An Oxygen Sensor Go Bad?

Similar to many different parts of a vehicle, oxygen sensors could wear down after lots of usage and begin to go bad. But if you aren’t paying attention, a bad oxygen sensor could begin to show huge problems all over your car. A build-up of contaminated oil ash or coolant could cause an O2 sensor to fail, so your choice in oil or gas is incredibly essential. If you’re seeing some problems like the ones seen above, you should come to our trained mechanics, who could set you up with an OEM O2 sensor replacement.

Can I Drive My Car With A Failed Oxygen Sensor?

It’s better that you don’t use your car with a bad O2 sensor as the engine isn’t running on the correct gas mixture. While it might seem okay in the beginning, if the engine is over-using its fuel and running rich it could begin to clog the catalytic converter. Considering the possible cost to replace oxygen sensors is much less than buying a catalytic converter, it’s worth making the investment now. Also, if your vehicle is more than 15 years old or has more than 60,000 miles on the road you should consider replacing your oxygen sensors for better engine performance and lower pollution.
