– The cost of replacing an oxygen sensor can range from $200 to $670 AUD, depending on the source and location .
– It is recommended to use an OEM or dealer-provided sensor for replacement to ensure compatibility with the vehicle’s computer system.
– Aftermarket sensors are available at a reduced cost, but there is a possibility that some vehicle computers may not recognize them, and it may be difficult to clear fault codes from the system.
Please note that these are general estimates, and the actual cost may vary. It is always a good idea to consult with a trusted mechanic or dealership for an accurate cost estimate for your specific situation.

What symptoms does a bad O2 sensor cause?

Signs a Vehicle has a Bad O2 Sensor

• Check Engine Light Comes On.
• Noticeable Loss of Fuel Efficiency.
• Sulfur or ‘Rotten Egg’ smell from Exhaust.
• Black smoke from exhaust.
• Emission levels reach high levels.
• Your engine hesitates, skips, begins bucking or has power surges.

What are signs of a bad O2 sensor?

Signs a Vehicle has a Bad O2 Sensor

• Check Engine Light Comes On.

• Sulfur or ‘Rotten Egg’ smell from Exhaust.
• Black smoke from exhaust.
• Emission levels reach high levels.
• Your engine hesitates, skips, begins bucking or has power surges.

How many hours does it take to replace O2 sensor?

Oxygen sensor replacement is normally a straightforward job. If your car has upstream and downstream O2 sensors, the latter tends to be more accessible and the job and should take a home mechanic under an hour.

What kills an oxygen sensor?

Also, a small amount of tetra-ethyl lead in the gasoline can kill an oxygen sensor. Over-the-counter fuel addi- tives, which are not “oxygen sensor safe” can also kill an oxygen sensor.

Is it OK to drive with a bad O2 sensor?

Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.

Are O2 sensors worth replacing?

The oxygen sensor of your car was not designed to work forever, and it needs to be replaced at some point during the life of your engine. Newer oxygen sensors are supposed to work efficiently for 60,000 to 90,000 miles, depending on the model of your car.

How do I know if it’s my catalytic converter or O2 sensor?

To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge. This is your baseline vacuum.

Should I replace all 4 O2 sensors at once?

Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.

Can I replace my O2 sensor myself?

Depending on the make and model, your vehicle could have 2 to 4 of them to replace. Even if you have minimal experience with cars, they aren’t hard to replace. Twist off the old sensors, install the new ones, and then appreciate how much better your vehicle runs.

What are the 3 common causes of O2 sensor failure?

Common O2 Failure Causes
Oxygen sensor failure can often be traced to one of three common factors: Age and high mileage, an internal contaminant (poisoning) or an electrical issue. One or two wire unheated oxygen sensors should be inspected or replaced every 30,000 miles.
