    My CEL light seems to be the result of only one code P1154. Which is Bank 2? Does the "Lower" refer to the downstream O2 sensor? Is there a most common problem that generates this code.....might be better to ask if there is a most common way to fix the cause of this code? Thanks for any input. Bill

    system too lean means air is too much.

    I'd say something is leaking air around your intake.

    Bank 2 is on lelft side of the car.
    Check leaking air (admission & exhaust) and fuel system (fuel pressure and injecteur flow)

    I had a similar code, p1160, and it was remedied by replacing the MAF sensor.

    Should also note that the right side MAF senses for the left bank (bank 2)

    That's because of the cross over design of the intake plenums and runners?

    Yes. You might try swapping the MAFs and see if the codes change.
