Malfunctioning Oxygen Sensor Signs

Lexus of Albuquerque can help you identify the malfunctioning oxygen sensor signs.

There are many unique sensors your vehicle utilizes on a day-to-day basis, perhaps one of the most important ones is an oxygen sensor, which is required for a vehicle to drive at its top-notch capability. Because of all of the exhaust gases any car produces, it’s important to have to be aware of the O2 levels left in the exhaust gases. The oxygen sensor plays an important part to play in keeping track of a vehicle’s O2 amount to make sure the engine is correctly burning its fuel. A good-working O2 sensor can be an essential component of a consistent running car. Still, a bad oxygen sensor can most likely cause bad fuel efficiency, bad smells from your vehicle, and a poorly performing engine. Here you’ll learn about things to watch out for when driving your car that could be easy-to-see symptoms of a poorly-working O2 sensor.

A Bad O2 Sensor Can Cause Problems, What Are They?

What Are The Issues A Failing O2 Sensor Could Cause?

Whenever you’re driving on the highway and smell anything rotten from your car, that can be a quick sign that the oxygen sensor is going bad. If you begin to pick up on some negative differences like bad powertrain performance, engine misfires, or loud noises, that can be a result of your O2 sensor potentially having issues. A huge issue a deteriorating oxygen sensor might happen is a sudden catalytic converter failure, which could cost a lot of money and might have your car in the shop for a bit.

My Car's Oxygen Sensor Is Failing, Why Did This Happen?

My Vehicle’s O2 Sensor Died, What Made This Happen?

Similar to many other parts of a car, O2 sensors can wear down over time and begin to fail. But if you don’t pay attention, a bad O2 sensor could begin to bring huge issues throughout your car. A build-up of contaminated coolant or oil ash could cause an oxygen sensor to fail, so a selection of gas or oil is super important. If you see some issues similar to the ones seen above, it’s best to come to our trained mechanics, who can set you up with an OEM O2 sensor replacement.

Is It Okay To Drive My Car With A Failed Oxygen Sensor?

Is It Possible To Drive My Car If It Has A Bad O2 Sensor?

We recommend against driving with a bad O2 sensor as your engine is not running on the right gasoline mixture. Though it may seem okay, if the engine is over-using its fuel it could end up clogging the catalytic converter. Considering the cost to get new oxygen sensors is much less than buying a catalytic converter, it’s worth making the investment now. Also, if your vehicle has over 60,000 miles or is more than 15 years old you might want to consider replacing your oxygen sensors for optimal engine performance and lower pollution.
