Inline 4-cyl engines only have 1 bank. The P0nnn codes are supposed to be generic across different car makers, so the discription of 'bank 1' or 'bank 2' makes sense for a V-6 or V-8 engine. Some of them might have separate O2 sensors for the banks.
Other than that, I guess your ECU thinks it's running too lean. Maybe you've got a vacuum leak? Maybe your O2 sensor is going bad?
