Bank 1 is the sensor located on the side with number 1 cylinder.

What motor do you have?

Codes never identify bad parts, just failed systems.

What was the code number?

Bank 1 sensor is closest to the exhaust manifold or upstream sensor.

No light indicates that it was out of parameter at some point but is working at this time. When it sets a hard code, then action needs to be taken
