What is an Oxygen Sensor?
An oxygen sensor, commonly called an O2 sensor, is an instrument mounted in the vehicles exhaust system that continually oversees the oxygen content in the gases that leave the engine.
How Does it Work?
The data from the oxygen sensor is used by the computer in the engine to assist in determining how much fuel is required so the engine will run as efficiently as possible. The sensor transmits this data by generating voltage once the sensor is heated. As the oxygen levels in the exhaust rise and fall the voltage will also rise and fall.
What are the Signs Related to a Faulty Oxygen Sensor?

What happens when O2 sensor is not working?
This voltage sends information to the vehicle’s electronic control module. Thus, if the sensor is not working properly, the computer must guess the amount of fuel that is necessary.
What is the purpose of oxygen sensors?
Most vehicles on the road today have internal combustion engines. To generate the power necessary to move the vehicle, the engine burns a precise mixture of fuel and air. This process, of course, creates certain emissions.
How many O2 sensors are there in 1980?
Both to improve engine efficiency and minimize emissions, vehicles manufactured after 1980 have at least one O2 sensor. With few exceptions, automotive internal-combustion engines require a oxygen-to-gasoline ratio of 14.7:1. If there is not enough oxygen in the mixture, excess fuel sticks around after combustion.

Advantages
Cost
- If you decide to do the repairs, the cost to replace the oxygen sensor yourself can be between $20-$94, depending on the brand and type of sensor you buy. To have the repairs done by a mechanic the price can be anywhere between $113 to $478 for parts and labor. The big difference in price is caused by the different prices of the sensor for certain ...
Operation
- Since 1980, the vast majority of cars have been fitted with an oxygen sensor. It works as part of the emissions controls, and communicates with the engine management computer to help the car run as efficiently as possible while producing lower levels of emissions.
Examples
- In a gasoline engine there is a particular ratio of gasoline and air that is perfect for combustion. If theres less air than the perfect ratio requires, there will be additional fuel left over after combustion. This is known as rich mixture. A rich mixture is problematic as it causes excess pollution and can negatively impact the atmosphere.
Purpose
- The oxygen sensor was developed to help combat this issue and prevent excess pollution or damage to the engine. Its typically placed in the exhaust pipe and it works to detect lean and rich mixtures, and works with the engines computer to help adjust the amount of fuel entering the engine. The result is less pollution, better performance and less money spent which is what we s…
Performance
- Having a working and accurate O2 sensor is essential for achieving optimal performance and fuel efficiency in your car. There are a number of variables which can affect the amount of oxygen available to the engine, such as air temperature, altitude, engine temperature, engine load, barometric pressure and more.
Symptoms
- There are several symptoms to look out if you suspect an issue with the oxygen sensor on your car. The first and most obvious sign will be that the check engine light will come on, and your mechanic should be able to confirm that its emitting an O2 sensor code. If the garage confirms that the sensor is damaged it will need to be replaced. There are more subtle signs to be aware …
Diagnosis
- When you take your car to the mechanic theyll usually run a few diagnostic tests to confirm the issue. Theyll use an OBD2 diganostic tool to confirm that the check engine light is sending out the code for the oxygen sensor. This process is commonly done during an automotive tune up and shouldnt cost any extra money to test for. If a car has more than one O2 sensor then the scan sh…
Use
- Once the problematic sensor has been identified by the engine computer, the mechanic will use an oxygen sensor socket to loosen and remove the device. The socket will fit on to a cheater bar and can be purchased from most major car part outlets, so if youre planning on making the repair yourself its a good idea to pick one up. The sensors tend to be fitted fairly tight, so its a good ide…
Risks
- When you take your car to a mechanic, youll be paying for the parts as well as the labor involved. Garages will often add a mark up to the parts, while the labor costs can often be quite expensive. Replacing the sensor is a job that most people should be capable of handling themselves, provided theres not a serious issue with the sensor. Occasionally it can rot into the …
