Changing oxygen sensors regularly helps in preventing problems in your car, it’s even inexpensive. They are important in checking the ratio of the air in the engine of your vehicle, as well as the gasoline and adjusting both when needed. There are different factors on which the amount of engine oxygen depends, such as the engine’s load, the barometric pressure, the temperature of the engine, the altitude, the air temperature around, and more. Be mindful of a rich mixture, it is when there is too much left over of fuel following combustion. More pollutants will be produced with nitrogen oxide in a lean mixture without a fuel that’s enough.

 

How do you know when your oxygen sensor is bad? Here are the signs!

 

Check engine light that glows

You’d see this sign in front of you on the dashboard. The glowing bright orange Check Engine light usually means you have a bad oxygen sensor. Another reason why the Check Engine light glows might mean another problem in the engine or a loose gas cap. When in doubt, have your vehicle checked by a professional or view smart DIY ideas on fixing vehicle problems here.

 

Unusual Gas Mileage

You better be thinking about what’s wrong with the unusual use of gas and more money spent on your vehicle’s fuel. When the ratio of oxygen to fuel is too lean or too rich, engines become less efficient and the oxygen sensors become less effective. You’ve probably wondered why there’s a gradual increase in your use of fuel, not an abrupt one.

 

Rough-Sounding Engine

It’s one of the most common sign when you have a bad oxygen sensor on your vehicle, it sounds rough when idle and runs irregularly. One of the impacts of a faulty oxygen sensor will be seen on the essential functions, the timing of the engine, and the interval of the combustion. There is also a noticeable slowed acceleration and stalling of the vehicle.

 

Failure in Emissions Test

Most failures on emissions test are due to faulty oxygen sensors. Failing to quickly replace a bad sensor may cost you thousands of dollars to get your vehicle running again. If you notice something smelling bad in your vehicle, like a rotten egg, it’s the faulty oxygen sensor at work exposing you and everybody else inside the vehicle with carbon monoxide.

 

Old Vehicle

Your oxygen sensors can be caked with combustion byproducts such as oil ash, lead, fuel additives, and sulfur. The signals from the sensor are not sent on the computer engine due to these byproducts. Note that gasoline with a low quality and fuels that aren’t recommended for your vehicle can contribute to a quick failure of your oxygen sensor.

 

Determine your car’s age. If it never went beyond 15 years yet, make sure you replace your sensors every 60,000-90,000 miles to reduce the pollution and keep the engine of your car smoothly running. If the car is more than 15 years already, be reminded to replace your oxygen sensor for every 45,000-65,000 miles.
