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.
How can you tell which O2 sensor is bad?
- 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.
What happens if you don't replace oxygen 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.
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.
How many O2 sensors do I have?
How many O2 sensors does my vehicle have? The number of O2 sensors depends on the number of the exhaust pipe. As required, each exhaust pipe has to be equipped with one catalytic converter, and for each catalytic converter, there are two O2 sensors . So there might be two, four, or six O2 sensors in your vehicle.
Can AutoZone test my O2 sensor?

What should my O2 sensors be reading?
An O2 sensor will cycle between 0.10 to 0.90 or almost 1 volt . An O2 sensor has to reach the 0.8x Volts amplitude mark while at full operation. An O2 sensor also has to reach the 0.1x Volts amplitude mark while at full operation. (Full operation means the engine is fully warmed up, O2 sensor above the 600 deg.
What side is bank 1 sensor 2?
The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2. On V6 and V8 engines, Sensor 1 will always be on the SAME side as the Number ONE cylinder in the engine's firing order.
How can you tell Bank 1 and Bank 2?
What is Bank 1 and Bank 2? Bank 1 and bank 2 simply refer to either side of the engine. Check your owner's manual or a service manual for a positive location of bank 1 and bank 2.
