A brand new replacement oxygen sensor can cost you from $20 to $100, depending on the make and year of your car. Taking your car to a mechanic to fix the issue can cost up to $200.
What happens if you don’t replace oxygen sensor?
If an oxygen sensor fails, the engine computer won’t be able to correctly set the air-fuel ratio, which could result in lower fuel economy, higher emissions and damage to other components, such as an overheated catalytic converter.
What causes an oxygen sensor to fail?
O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a crack in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).
How can you tell which O2 sensor is bad?
Here are some of the most common signs that your oxygen sensor is bad.
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
- Bad Gas Mileage.
- An Engine That Sounds Rough.
- An Emissions Test Failure.
- An Older Vehicle.
Is it hard to replace an 02 sensor?
In most vehicles, replacing an oxygen sensor is a simple procedure that requires only a few tools. However, if this is not a task you are comfortable doing on your own, this is something that any professional technician, such as one from YourMechanic, can take care of quickly and easily.

What does a car do when the oxygen sensor is bad?
If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
How long does it take a new O2 sensor to work?
The rear 02 sensor takes about 10 minutes to replace on a bad day count on another 10 minutes to check/reset any codes in the engine computer. whole job should not be more than 1/2 hour. The upstream sensor would take about 1.2 hours to replace and the total for parts and labor is $206.08.
How much does it cost to replace oxygen sensor in Subaru Outback?
Subaru Outback Oxygen Sensor Replacement costs $471 on average. What is the Oxygen Sensor all about? With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation.

What happens if the oxygen sensor goes bad on a Subaru Forester?
When an O2 (oxygen) sensor go bad, it’ll cause your Subaru Forester ‘s engine to run less efficiently. Your Forester can exhibit symptoms when the Oxygen sensor has gone bad.
When to replace an oxygen sensor in a car?
New vehicles require specific oxygen sensors, and not the universal sensors that were common prior to 1996. Scan the computer in the car for codes. Inspect for vacuum leaks and holes in the exhaust system. Remove and replace the oxygen sensor if it is bad. Check electrical connections. Check for proper operation of oxygen sensors.
What happens if your O2 sensor is bad?
The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly. Without being able to optimize the air fuel ratio, combustion isn’t as efficient, and fuel mileage suffers.
