Where are Bank 1 and 2 O2 sensors located?
Summary. If your DTC code says: Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after the catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is the O2 sensor on a catalytic converter?
Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is Bank 2 located on an engine?
Located on Bank 2 means it is located at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter.

Where are the oxygen sensors on a Chevy Prizm?
The Chevrolet Prizm comes equipped with two oxygen sensors. Technically, they are referred to as Bank 1 Sensor 1 (located near the front of the Prizm) and Bank 1 Sensor 2 (threaded into the back exhaust pipe, near the catalytic converter). Depending on your diagnostics, you may need to replace one or both sensors.
How does the O2 sensor work on a truck?
O2 sensors measure the oxygen levels in your truck’s exhaust gas before and after passing through the catalytic converter. By measuring the amount of oxygen leftover after engine combustion, the truck’s on-board computer can adjust the air-to-fuel ratio accordingly.
What are the downstream O2 sensors on a Nissan?
One or two sensors will be downstream, B1S2 and B2S2. The procedure is similar for the downstream O2 sensors (Bank 1 & 2, Sensor 2). For the downstream sensors, you will find it easier to access the O2 sensor from underneath the car.
