Temporary Fix for a Bad O2 Sensor
If you use your vehicle for racing or greater performance, you may want a temporary fix for a bad O2 sensor so that you can tune the engine without causing a system error and the “check engine” light code. A temporary fix for a bad O2 sensor is to bypass it by using a dummy O2 sensor.
Why You Need to Fix a Malfunctioning O2 Sensor
Let’s assume that all the components of your car are working properly. However, if it has a bad oxygen sensor, your fuel consumption will go to the roof. This seemingly inconsequential problem can reduce your car’s fuel economy by up to 40%. Your mpg will take a hit if you don’t fix this issue.
What Is an Oxygen Sensor?
It was in the early 1980s when the earliest oxygen sensors were developed. An oxygen sensor is a critical part of the emission control system of a vehicle. It is similar to the shape and size of an ordinary spark plug. A standard car engine has several oxygen sensors that protrude in its exhaust system.
Signs of Bad Oxygen Sensor
Before an oxygen sensor fully goes bad, it will show some manifestations of its deteriorating condition. You need to watch out for these signs or symptoms:
When to Replace the Oxygen Sensor
When an oxygen sensor malfunctions, the only way you can fix the problem is to replace it. If you don’t, the performance of your car engine will deteriorate. Unfortunately, replacing oxygen sensors is not usually a part of the car dealer’s standard service schedule. They won’t touch an oxygen sensor, especially if your car’s mileage is still low.
Cost of Oxygen Sensor Replacement
If your car needs a new and good quality O2 sensor, prepare $50 to $100. Replacing it will not take many hours. A qualified mechanic should do everything, from scanning to the actual replacement, in about a couple of hours only.
How to check if a car sensor is working?
First, switch on the PDC (Park Distance Control). With this one, get as close as you can to the sensor and put your ear near it. Listen to see if there is a buzzing sound. If there is, then the sensor itself is working. If you cannot hear anything or if you do not want to put your ear that close to the sensor then you can simply put your finger up against it. If the sensor is vibrating just slightly, then there's no need to replace it. However, if there is no buzzing or slight vibration, go ahead and remove the sensor and take it to your local automotive store to purchase a new one.

What happens if oxygen sensor is not working?
Trouble in the Air. A sluggish or inoperative oxygen sensor can cause a rise in unhealthy emissions and create poor fuel economy. If the engine doesn’t have the proper real-time data from the sensor, it might default to a predetermined air-fuel mixture with no regard for how the vehicle is actually being driven.
How long do oxygen sensors last?
A common cause of the dreaded check engine light, failed oxygen sensors have a life expectancy of anywhere from 35,000 to 50,000 miles. It’s a unique sensor with impressive technology for something the size of a spark plug — it’s the only sensor that generates its own voltage using a heat-induced chemical reaction.
Where is the O2 sensor located?
Some vehicles have more than one O2 sensor, but they are all located somewhere in the exhaust system and operate on the same principle: The sensor measures the difference in oxygen levels between outside air and what is present in the exhaust gas, and sends a variable voltage signal to the engine’s central computer.
