  1. Replacing the O2 sensor for bank 1 sensor 2.
  2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
  3. Replacing the catalyst in front of the sensor.
  4. Repairing a leaking injector.

Where is the downstream sensor located?

The downstream oxygen sensor is located directly after the catalytic converter. This sensor measures the pollutants making it through the converter and out of the tailpipe. The data from this sensor is compared to that of the upstream sensor.

How do I know if it’s my upstream or downstream O2 sensor?

The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine’s exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio.

Are both oxygen sensors the same?

Physically, there’s no difference between front and back O2 sensors. They function in the same way, but the vehicle’s computer uses the measurements that they take for different purposes.
