What happens when an oxygen sensor goes 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 many O2 sensors does a 2000?
Your Parts supply company should be able to tell you for sure but you will have between 3 -4 o2 sensors.
Where is the oxygen sensor on a 2000?
You’ll find the upstream O2 sensor right on the exhaust manifold and the downstream O2 sensor near the catalytic converter. To find the downstream sensor, follow the front exhaust pipe that connects to the exhaust manifold down towards the catalytic converter.
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.
Where can I get an oxygen sensor for my Hyundai Sonata?
Pick Up In-Store. Boasting a sleek exterior and equally impressive and well-equipped interior, your Hyundai Sonata is your home away from home. Make sure its engine delivers for years to come by swapping out that old, tired oxygen sensor in favor of a new Hyundai Sonata oxygen sensor from AutoZone.
Where are the oxygen sensors located in a car?
The sensors are located along the exhaust system, which gets very hot when the vehicle is in use. Touching the engine, for instance, is dangerous. Turn the vehicle off and give it about 30 minutes to cool. 
What’s the best way to change an O2 sensor?
You may have more than one. Unplug the wire at the connector and remove O2 sensor. They do sell a special tool, but you can do it with a crescent wrench. Use some liquid wrench first. Apply anti-seize to the threads of the new O2 sensor for ease of installation and reconnect the wire.
When do you Know Your oxygen sensor is bad?
The first indication of a problem with your vehicle’s oxygen sensor is often when the “check engine” light comes on. Failing sensors cause jerky movements, trouble starting, and reduced fuel efficiency if they aren’t replaced. Oxygen sensors are necessary for vehicles to combine the proper ratio of gas and oxygen into fuel.
Are all 4 wire oxygen sensors the same?
There are 2 types of narrowband O2 sensors, titania and zirconia. Most cars use zirconia sensors and they’re all interchangeable as long as they have the same number of wires, even then you could get away with using a 3 wire sensor in place of a 4 wire if you really had to. Not sure what the B5 uses though.
Can I drive my car if the oxygen sensor is bad?
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.
Are oxygen sensors universal?
Oxygen sensors have been standard equipment on almost all passenger cars and light trucks with gasoline engines since 1980-1981. Bosch has created an aftermarket universal heated oxygen sensor program. These sensors meet OEM operating requirements and have a patented connector system easing installation.
What causes an oxygen sensor to fail?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
Are Bank 1 and Bank 2 O2 sensors the same?
Bank One is always the bank where cylinder number one is located. On the Corvette it will always be the driver side. Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine.

When did the universal oxygen sensor come out?
Premium Universal Oxygen Sensors with OE SmartLink are quick and easy to install. Each sensor has two-feet length of sensor wire to allow maximum replacement of worn harnesses. It’s been more than 40 years since Bosch invented the Oxygen Sensor and began series production in 1976.
What does Bosch Universal heated oxygen sensor do?
Bosch has created an aftermarket universal heated oxygen sensor program. These sensors meet OEM operating requirements and have a patented connector system easing installation. This connector system has been proven to be watertight, protect against contamination, and withstand the effects of extreme temperatures and engine vibration.
Where are the oxygen sensors on a car?
Most vehicles built before the mid-90’s have one or two oxygen sensors (two were used on selected V6 and V8 engines starting in the late 1980s). Oxygen sensors are normally located in the exhaust system before the catalytic converter to measure exhaust emissions as they come from the engine combustion chambers.
