No, you don’t need a special tool like the stripped o2 sensor removal tool to remove your vehicle’s O2 sensor. Although nothing beats using the right tools for the right job, you could easily remove it without a special tool.

How much does it cost to replace oxygen sensor BMW?
The Best in Auto Repair The average cost for a BMW 328i oxygen sensor replacement is between $682 and $920. Labor costs are estimated between $175 and $221 while parts are priced between $507 and $699. This range does not include taxes and fees, and does not factor in your specific model year or unique location.
Can I replace oxygen sensor myself?
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.
Should I replace both oxygen sensors at the same time?
It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.
What are the symptoms of a failing oxygen 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.
Can you drive with a faulty oxygen sensor?
Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
What happens if you don’t replace O2 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.
Does AutoZone replace O2 sensors?
After all, if you have a bad or failing O2 sensor, you could get reduced gas mileage or even fail an emissions inspection. If you have noticed some bad O2 sensor symptoms and are ready to replace your sensors, AutoZone has everything you need to do the job right.
Why is my check engine light still on after changing O2 sensor?
You need to clear the code once a repair is done. If you replaced the oxygen sensor just because the light is on or because you had a code for an oxygen sensor, doesn’t mean a new sensor will correct the problem.
How can I temporarily fix my o2 sensor?
How much does it cost to replace both oxygen sensors?
Cost at the Mechanic: $275 to $500 The final price of the parts required can run you anywhere from $155-$380 depending on how many sensors you need replaced and their quality. Labor typically costs around $120, with the average amount of labor time required being 1 hour.
How long do oxygen sensors last?
Generally, oxygen (O2) sensors last about 30,000-to-50,000 miles if you have an older car. Newer sensors can go 100,000 miles before they need to be replaced. University Auto Repair lists six signs below that your vehicle’s oxygen sensor is dying.
What kills an oxygen sensor?
MALFUNCTIONING AND FAILED SENSORS Oxygen sensors can fail when the sensor’s ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine leads to the sensor becoming oil-fouled. Also, a small amount of tetra-ethyl lead in the gasoline can kill an oxygen sensor.
How often should O2 sensors be replaced?
All cars and trucks that were made in the last fifteen years should have their O2 sensors replaced every 60,000 to 90,000 miles. Replacing your sensor at these intervals will lower the level of pollution that your vehicle emits while playing a preventive role in the cause of damage to the vehicle.
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.
Can a bad O2 sensor cause catalytic converter failure?
Yes, the oxygen sensor can damage the catalytic converter, although the damage is indirect. What actually happens is that the oxygen sensor malfunctions and sends incorrect data to your vehicle’s main computer chip.
Should I disconnect battery when changing O2 sensor?
Should I disconnect a battery before changing an O2 sensor? Any time you work on anything electrical in your car, you should first disconnect the battery by removing both cables then short them for 30 seconds together to completely drain the system of electrical energy.
What problems can a bad O2 sensor cause?
A bad O2 sensor in your vehicle can cause several problems. It can cause your engine to run lean, or too much air and not enough fuel. This can lead to decreased fuel economy and increased emissions. In some cases, it can cause your engine to misfire or run rough.
What is the code for a bad oxygen sensor?
Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. This will usually have a diagnostic trouble code (DTC) of P0138. Typically, you’d take the vehicle into the shop, where they’d diagnose the issue and replace the oxygen sensor for you.
Which O2 sensor causes check engine light?
Faulty O2 Sensors The oxygen sensor, also known as the O2 sensor, measures the amount of unburnt oxygen in your exhaust system. A failing sensor can cause the check engine light to be triggered, though you can continue to drive relatively fine with it.
Does O2 sensor affect gas mileage?
Poor Fuel Economy The oxygen sensor can affect how much fuel your vehicle’s engine burns. By measuring oxygen levels in the exhaust, the O2 sensor helps to ensure your automobile meters and delivers the correct amount of fuel depending on the demands you place on the engine.
How do you test an oxygen sensor?
- Make sure the engine exhaust system is cold.
- Switch the clamp-meter on, to ‘DC current/DC amperage’ mode.
- Put the clamp around either of the oxygen sensor heater power wires (but not both).
- Turn the engine on.
- Observe the reading, which should be between 0.25A and 1.5A.
Do catalytic converters come with oxygen sensors?
There are two types of O2 sensors in new vehicles: the upstream O2 sensor and the downstream O2 sensor. These sensors are before and after the catalytic converter in your overall exhaust system and are also referred to as Sensor 1 and Sensor 2.
How do you turn off check engine light on O2 sensor?
How do you clean an O2 sensor without removing it?
