Yes, if your car has a single catalytic converter and a single exhaust pipe, you need to repair two oxygen sensors. Remember not to mix them up; the sensor for upstream before the catalytic converter is different from the one behind the converter. One sensor is in the front and another is behind the catalytic converter.

O2 sensors upstream are crucial for engine performance.
The number of O2 sensors in the Hyundai Sonata varies depending on the model year and how the car is configured. The upstream O2 sensor, which is typically located in the exhaust manifold and is the nearest to the engine, is however the most crucial. For best fuel efficiency and engine performance, the upstream O2 sensor aids in maintaining the proper air to fuel ratio in the combustion chambers. Any problem with this sensor could result in a variety of performance problems for your Sonata.

What does a Hyundai oxygen sensor cost?
The Best in Auto Repair An oxygen sensor replacement for a Hyundai Elantra typically costs between $284 and $326. Between $39 and $50 is the projected cost of labor, while $245 to $276 is the estimated cost of parts. Taxes and levies are not included in this range, nor are your particular model year or special location taken into account.
Must I swap out all four O2 sensors at once?
O2 sensors should ideally be changed in pairs. For instance, you should replace the downstream right sensor if you replace the downstream left sensor.
On the majority of cars made after 1996, the ECU will set a code for the other sensors if one sensor is replaced, particularly the front engine monitoring sensor. This is due to the fact that new sensors switch activities considerably more quickly than do older, more seasoned sensors. On the majority of vehicles, the code is likely to be set between 30 and 60 days AFTER the first sensor replacement.
How can you identify the bad O2 sensor?
- Check engine light that is illuminated. If you have a malfunctioning oxygen sensor, your dashboard’s bright orange Check Engine light will often glow.
- poor gas mileage
- A rough-sounding engine
- Failure of the Emissions Test.
- A more aged vehicle
How many 02 sensors are there in a four-cylinder?
Two oxygen sensors, one before and one after the catalytic converter, are present in the majority of more recent automobiles with 4-cylinder engines. More oxygen sensors are included in some V6 and V8 automobiles to help monitor their intricate systems.
Does it pay to replace the O2 sensor?
Further inspection is always necessary because an illuminated check-engine light may indicate either a simple problem, such as a loose gas cap, or something more significant, such as a problem with the catalytic converter. However, it can be an indication of an issue with your O2 sensor or possibly another component of your exhaust or emissions system. Your check-engine light should be readable by any repair business, and a mechanic or auto parts retailer may do this at no charge.
A rough idle, misfiring spark plugs, a lack of power, stalling, or a considerable rise in fuel consumption are further indications that you need a new oxygen sensor. The EPA claims that changing a defective oxygen sensor can increase fuel efficiency by as much as 40%, so obviously that is one place to look if your car starts to use more petrol. However, same symptoms could also be signs of other issues. A broken O2 sensor may also be to blame if your car fails an emissions test.
Without factoring in labor, the price of a new oxygen sensor can range from less than $100 on some models to $300 or more on others. This is because labor costs depend on where the sensors are positioned in the vehicle. As a result, depending on the type of vehicle you drive, the total cost of oxygen sensor replacement may differ significantly.
If I unplug my O2 sensor, what happens?
If someone is really committed to enhancing their car’s performance, they will typically remove the oxygen sensor. When installing performance accessories like exhaust headers and nitrous, your O2 sensor will frequently detect excessive levels of pollution and unburned gasoline in the exhaust flow. These measurements might force the ECU to inject less fuel, which would prevent performance improvement. Not to add that the check engine light will also come on as a result of the O2 sensor.
The performance was fine overall. O2 sensors, however, are added to give the average person the best possible ride: one with strong performance, good fuel efficiency, and minimal pollution. Your ECU can no longer determine how much fuel should be injected if the O2 sensor is removed. The ECU will revert to its default setting and consistently inject the same amount of gasoline. Low performance or terrible fuel economy may result from this.
O2 sensor: Can fuel injector cleaning help?
The simple answer is that B-12 Chemtool Total Fuel System Clean-Up (part #2616), our strongest gasoline fuel additive, and a thorough tune-up might help you out.
True oxygen sensor cleansers that are secure to run through your engine don’t exist. We do not advise trying to clean O2 sensors, even if some users choose to remove them and use a wire brush or an aerosol cleaner to remove deposits.
We believe their function is too important to risk the sensors being harmed and inadvertently (and mistakenly) changing the air-fuel ratio. The threads on the sensor(s) might not be able to withstand repeated removal and installation cycles. They occasionally don’t even make it through an entire cycle!
Is there a cleaner for O2 sensors?
As I can’t accelerate over 40 mph, I think the O2 sensors and/or catalytic converter are blocked and need cleaning. What do you suggest?
The simple answer is that B-12 Chemtool Total Fuel System Clean-Up (part #2616), our strongest gasoline fuel additive, and a thorough tune-up might help you out. The lengthy response is as follows.

You cannot directly clean a catalytic converter while it is still attached to the vehicle because anything that may be safely put through the engine will be transformed to CO2, O2, and N2, none of which will perform any cleaning. A “catalytic converter cleaner” is gimmicky in that regard. You do, however, have a few choices.
Catalytic converters should actually last the lifetime of the vehicle since, under certain circumstances, they “self-clean.” Running a high-performance fuel system cleaner like 2616 and making sure the engine is correctly tuned-up can both be of great assistance if the engine’s “guts” are physically sound but there is just little build-up on the catalysts. The two processes work together to “fix” or idealize the combustion products, which enables the catalytic converter to start burning/shaking off the deposits and reactivating.
However, nothing can be done to revive them if the catalysts or the supporting structures are physically harmed. This may occur, for example, when unburned fuel exits the combustion chamber after an extended period of time due to old or defective spark plugs, a broken spark plug wire, filthy combustion chambers, etc. When this happens, the catalytic converter may become overheated and eventually begin physically disintegrating. If this has occurred, there is no cleanser in the world that can fix it; instead, the component must be changed.
We offer a dual recommendation as a result of these factors. Fuel lines, fuel injectors, intake valves (in non-direct-injection motors), and combustion chambers can all be cleaned using 2616. Then, having the car tuned up will make sure that unburned fuel is not getting into the exhaust system. Pay close attention to the ignition system, especially the spark plugs and plug wires. You must drive the car for a long time after running the 2616 and obtaining the tune-up in order to hopefully burn off any deposits that have fouled the catalysts. The best places to drive are on the highway or places with few start-stop cycles. I wish you luck!
The bank 1 sensor 2 is which 02 sensor?
Bank 1 The first sensor, which is closest to the engine, is Sensor 1. On Bank 1 denotes that the cylinders 1, 3, 5, 7, etc. are on the engine side.
The second sensor on the engine’s exhaust pipe, often located after the catalytic converter, is known as Bank 1 Sensor 2. On Bank 1 denotes that the cylinders 1, 3, 5, 7, etc. are on the engine side.
The first sensor nearest to the engine is Bank 2 Sensor 1. On Bank 2 denotes that the cylinders 2, 4, 6, 8, etc. are on the engine side.
The second sensor on the engine’s exhaust pipe, often located after the catalytic converter, is known as Bank 2 Sensor 2. On Bank 2 denotes that the cylinders 2, 4, 6, 8, etc. are on the engine side.
Are O2 sensors used upstream and downstream identical?
Regarding your 2013 Chevrolet Cruze, the upstream and downstream oxygen sensors are not the same. The upstream oxygen sensor, also known as an air fuel sensor, is positioned before the catalytic converter and used to compute the air fuel mixture. The downstream sensor, which reads the emissions after the catalytic converter, is a heated oxygen sensor. They are similar in function but sufficiently dissimilar to prevent swapping. A skilled expert from YourMechanic may visit your location to assess the system and replace any defective O2 sensors if you need assistance getting this checked or fixed.

How long may a broken oxygen sensor be used while driving?
If your engine can still start and you have just minor problems driving, then yes, you can drive with a bad oxygen sensor. However, don’t leave it unattended for more than a few days since this could compromise vehicle safety and cause other components to go down.
A defective oxygen sensor may result in stalling, sluggish and difficult driving, poor fuel economy, and significant emissions. And if you leave it there for several months, it can result in expensive repairs or replacements for the catalytic converter and engine.
As a result, you must check the oxygen sensor as quickly as possible, perhaps by visiting a mechanic on the weekend. If you possess a car diagnostic kit, you may read the OBD2 code, look up potential causes online, and try a number of straightforward repairs. Cleaning the O2 sensor or changing a linked pipe may occasionally be able to clear a fault code indicating an O2 sensor issue.
Oxygen sensors in banks 1 and 2 are identical, right?
The sensors in banks 1 and 2 are comparable. Nevertheless, bank 1 contains two sensors: sensor 1 is positioned close to the engine before the catalytic converter and is known as pre CAT; sensor 2 is positioned after the catalytic converter and is known as post CAT.
On the other hand, Bank 2 has two sensors of its own: sensor 1, an upstream sensor that is placed close to the engine before the CAT, and sensor 2, a downstream sensor that is placed after the CAT. In each engine, bank 1 and bank 2 sensors are therefore similar.
