Good morning welcome to just answer I am master tech and will be able to assist you today.

bank one is at the firewall,sensor 2 is the second

Let me start over. I have a code P2195 on bank 1 sensor 1 and codes P2240 and P0154 on bank2 sensor 1
Expert:  MASTER TECH replied 1 year ago.

im sorry for some reason I got the info all confused.

ok your air filter can contribute to these codes but to proceed we need to address the issue at hand first.

replace the air filter and then clear the dtc's and road test.

most likely you have a failing 02 sensor but after clearing the codes you should get one primary code.
