How much should the replacement of an oxygen sensor cost?
Their guide states that you can save money by replacing your oxygen sensors yourself and only spend around $20 to $94. Labor price estimates range between $76 to $97, while parts prices range between $485 to $493. Estimates don’t include taxes and fees.
How much is the cost to replace the oxygen sensor?
The nice thing about oxygen sensors is that they don’t require replacement very often. Even better, if you are mechanically inclined, changing out your oxygen sensor or oxygen sensors is something that you can probably do on your own. Replacing an oxygen sensor can cost anywhere between $348 and $363, but a good estimate is about $356.

Which oxygen sensor needs to be replaced?
When to replace the sensor. If your vehicle was manufactured within the past 15 years, the oxygen sensor should be replaced every 60,000 to 90,000 miles. This sensor does wear out and will need replacement over time.
Are O2 sensors worth replacing?
Oxygen sensors are not among the maintenance items that need to be replaced regularly, such as oil and air filters, so they typically are replaced only when they fail.
Can I drive with a failing O2 sensor?
In summary, yes, you can drive with a faulty O2 sensor. But you'll want to change it immediately, because otherwise, you'll be spending more money on fuel whether during the daily commute or an out-of-town leisure trip, and you risk having to spend more on a new catalytic converter as well.
What happens when an oxygen sensor goes bad?
When an O2 sensor goes bad, it can no longer trigger accurate fuel injection levels, regulate exhaust gas, or ensure efficient fuel combustion. Consequently, the vehicle may release harmful environmental pollutants or carbon-based compounds – in addition to having subpar engine performance.
What causes an oxygen sensor to fail?
Over time, your oxygen sensors can become caked with byproducts of combustion like sulfur, lead, fuel additives, and oil ash. This keeps your sensors from sending signals to your engine's computer. Using fuel that isn't recommended for your vehicle or low-quality gasoline can make your oxygen sensors fail faster.
How long does it take to replace an O2 sensor?
Most of the time, it will only take a skilled mechanic about 30 minutes to replace an O2 sensor. In some cases, however, it can take up to an hour or more. On average, replacing an O2 sensor should take 20-40 minutes with a median time of 30 minutes.
Will check engine light reset after replacing O2 sensor?
Hi There, The last diagnosis is correct in that the sensor replaced caused the check engine light to turn off. In some cases they do not always turn off immediately and take a bit of driving for the computer to recalibrate and recognize that the problem has been corrected.
How long do oxygen sensors last?
And lastly, how long do oxygen sensors typically last? Older vehicles have O2 sensors that will typically last 30,000 to 50,000 miles, or 3 to 5 years. Newer vehicles employ sensors with an additional heated element and these new sensors are more likely to last to 100,000 or 7-10 years.
Can a bad O2 sensor cause transmission problems?
A faulty oxygen sensor will cause the engine to run less efficiently (use more gas than usual) and may degrade engine performance to some extent. However, failure of the oxygen sensor itself can not cause the transmission to fail or operate poorly.
Will check engine light reset after replacing O2 sensor?
Hi There, The last diagnosis is correct in that the sensor replaced caused the check engine light to turn off. In some cases they do not always turn off immediately and take a bit of driving for the computer to recalibrate and recognize that the problem has been corrected.
How do you fix a broken O2 sensor?
Typically, you cannot repair a faulty O2 sensor. It must be replaced because of the technology and materials in its housing. There are some DIY places that will tell you how to clean the sensor to get a few more miles out of it, but you're only delaying the inevitable.
Can you clean an O2 sensor?
There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.

How does an oxygen sensor work?
How does the oxygen sensor work? The information from the oxygen sensor is used by the engine's computer to help determine how much fuel is needed so that the engine will run efficiently. The sensor sends this information by producing voltage when the sensor is heated. The voltage rises and falls as oxygen levels in the exhaust rise and fall.
Where is the oxygen sensor located?
The oxygen sensor, sometimes called an O2 sensor, is a device mounted in the exhaust system that constantly monitors the oxygen content in the gases that exit the engine. Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
What are the symptoms of a bad oxygen sensor?
Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.
Can a car run with a bad oxygen sensor?
A vehicle that has a bad oxygen sensor can be driven safely until the sensor can be replaced. But the car will not run as well until the repair is made. Oxygen sensors can fail if they are contaminated with oil, coolant or silicone.
Cost Estimates for Oxygen Sensor Replacement
Labor price estimates range between $76 to $97, while parts prices range between $485 to $493. Estimates don’t include taxes and fees.
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?
A faulty oxygen sensor is one of the more typical causes for a check engine light to come on. Signs can include misfiring or hesitation from the engine, decreased fuel mileage, idling roughly or possibly stalling. A vehicle that fails an emissions test could be caused by a faulty oxygen sensor.
Is it Safe to Drive With a Problematic Oxygen Sensor?
A vehicle that has a faulty oxygen sensor may be driven safely until replacing the sensor. However, the vehicle won’t run as efficiently until the sensor is replaced.
How Often are Oxygen Sensors Required to be Replaced?
On vehicles made since 1996, their oxygen sensors can go up to 100,000 miles or more prior to needing it to be replaced. That mileage will decrease on vehicles that are older.
Can I Replace the Oxygen Sensor Myself?
There is a pretty considerable disparity in cost between a professional mechanic replacing the vehicle’s Oxygen Sensor and replacing it yourself. If you feel you’re comfortable replacing it, you should try to replace the oxygen sensor yourself, because it’s a pretty simple job, it can save you 100’s of dollars.
Why are oxygen sensors damaged?
Many oxygen sensors are damaged by leaking oil or coolant. If that is the case, the cause of that leak needs to be identified and repaired, or else the replacement oxygen sensor will be damaged as well. New vehicles require specific oxygen sensors, and not the universal sensors that were common prior to 1996.
What happens if you drive a car with a faulty oxygen sensor?
If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter. Oxygen Sensor-MATROX-1.
Why do cars need oxygen sensors?
Because cars depend on an ideal fuel-to-air ratio to function optimally, the oxygen sensors are leaned on for engine performance. When your oxygen sensors fail your car will run less smoothly, get worse mileage, and have worse emissions.
What to do if your check engine light is flashing?
If check engine light is flashing, pull over and get the car towed to avoid costly repairs. Ask the mechanic to inspect the vacuum hoses and leaks in the exhaust system. If the vacuum hose or exhaust system is leaking, it will display an oxygen sensor fault code. Replacing an oxygen sensor may not fix the problem.
What does the front sensor do in a car?
The front sensors measure how much oxygen is in the exhaust stream to measure how rich or lean the gases leaving the gas chamber are. The rear sensors measure the oxygen content of the gases as they leave the catalytic converter.
