Default Volvo s80 2001 2.9L P1152 error code

Hello. I have a Volvo s80 2001 2.9L. Lately the started to vibrate, I connected a scanner and go a P1152 error code. I know that it means that there is a problem with one of the oxygen sensors (lambda) but I donít know which one of them are where itís located in the car.
Appreciate any help.
Dan.

O2 sensors are located on the exhaust system - the upstream sensor (ie between the engine and catalytic converter) is considered the lambda sensor and provides the measurement for the fuel mixture. This code is saying your engine is running rich. The downstream sensor is used to measure catalytic converter efficiency.

The fact that your engine is running poorly is saying the data from the 02 sensor into the ECU is not compensating for the fuel mix being too rich. This can be due to a faulty upstream O2 sensor or an intake air leak or dirty intake/MAF which is forcing the sensor out of range. You can unplug the sensor (should be up on the firewall) to test the sensor before replacing

I have a screenshot of the error


Here it says that the fuel mixture is lean but what does "Bank 1" mean? does it indicate that bank 1 O2 sensor is faulty and if so where the bank 1 sensor is located?

bank 1 and bank 2 refer to the cylinders - if you have an I5 or I6 there's only bank 1 if you have a single exhaust. If you have a V8 or a dual exhaust (ie 3 into 1 for the first 3 cylinders and 3 into 1 for the 2nd 3, bank 1 refers to the first side.)
