Ok. 2003 f150 v6 automatic running lean. Had codes for bank 2 sensor 1 and bank 1 sensor 1. I think I fixed the air leaks, now it's saying both sensor 2 s need maintenance. What could be the problem. How do I add pictures.

Now the thing is the oxygen sensors report problems that the vehicle has and just because you have a code for them doesn't need the sensors are bad. More often when they're running lean you have an air leak or the mass air flow sensor isn't working correctly or the fuel filter is clogged or the fuel pump itself is just weak and should be pressure tested to see if it's going up
Just changed fuel filter. It's just odd that the codes jumped from bank 1 sensor 1 to bank 1 sensor 2 on both sides. What voltage should the sensors be at to see if they are working properly
Air flow sensor is fairly new
