It might be the catalytic converter. Your o2 sensors are generally located front and rear of the cat and if they are working it means you are not getting proper air flow. You might want to check/change the air filter and clean or replace the MAF sensor

Hi there,
We have detailed facts about all the trouble codes you provided. Click this link for more info about trouble code P0135. For trouble code P0141, you can check this link. Now for code P0155, this link might help. Lastly, click this link for trouble code P0161. In summary, the trouble codes indicate faulty oxygen sensors for banks 1 and 2, and sensors 1 and 2. Sensor 1 is the front/upstream oxygen sensor and sensor 2 is the rear/downstream sensor. I hope this helps!
