How many O2 sensors does a Hyundai Elantra have? Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
How can you tell which O2 sensor is bad? Several of the most obvious signs that the oxygen sensor is failing include:
Reduced gas mileage.
A bad smell like rotten eggs coming from the exhaust.
The check engine light comes on.
You notice that your engine idles roughly.
The car is suddenly hard to start.
Do you need 2 O2 sensors? O2 sensors are mandatory on all cars manufactured since 1981. Cars made in 1996 and after are required to have a second oxygen sensor that is located below the catalytic converter. This O2 sensor monitors the operating efficiency of the catalytic converter.

Where are O2 sensors located?
The oxygen sensor helps keep that balance in check. The sensor is typically located on the passenger side of the car, mounted directly onto the exhaust pipe near the catalytic converter. When the sensor goes bad, your car may lose up to 40 percent of its fuel efficiency, because your car will use too much gas.
Can I drive with a bad O2 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.
How long does it take for the check engine light to go off after replacing the O2 sensor?
Or it will usually clear itself after driving it a few times or sometimes after a full drive cycle 20 to 30 minutes.
How do I know if my upstream or downstream oxygen sensor is bad?
A decrease in fuel efficiency can be a telltale sign that an O2 sensor is not performing as it should. This can happen because of a fuel mixture that is either too lean or too rich. Such a swing in A/F ratio is a sign that an upstream or control sensor is faulty.
Can AutoZone test my O2 sensor?
Of course, if you have questions about your O2 sensors or anything else automotive, our knowledgeable AutoZone associates are always ready to help.
Can an O2 sensor be cleaned?
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 much does it cost to fix O2 sensors?
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 I disconnect my O2 sensor?
With the O2 sensor removed, your ECU can no longer calculate how much fuel should be injected. The ECU will fallback to its default value and always inject the same amount of fuel every time. This could cause either low performance or horrible fuel economy.
How long does it take a new O2 sensor to work?
It takes about ~40 trips (on/off cycles) for the ECU to reset the code itself. If you have a scanner to reset the code, it will not clear the learned info that the ECU has stored.
Can Oxygen Sensor go without check engine light?
If an O2 sensor is not reading properly or is borderline, it should be replaced regardless of its age or mileage. If there’s no Check Engine light or any codes that might suggest an O2 sensor related fault, he has no way of knowing if any O2 sensors need to be replaced.
What side of engine is Bank 1?
Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine. Check out the pics below to see several different configurations. Tech Tip: The front of the engine is not the part closest to the front of the car.
Is bank 1 sensor 1 upstream or downstream?
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
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).
Are O2 sensors hard to replace?
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.
Will a new O2 sensor improve performance?
Will a new o2 sensor improve performance
Should you replace all O2 sensors at the same time?
O2 sensors are a “wear item” and are recommended to be replaced every 75k mi.
(if I remember correctly, check the FSM).
Consider them part of a really proper tune-up regimen.
Can bad spark plugs cause O2 sensor code?
If spark plugs are misfiring (fuel isn’t ignited in those cylinders) so there will be excess oxygen (because it wasn’t consumed by the burning fuel). The O2 sensor ahead of the catalytic converter will detect this and the ECM will set a code.
