    Post the file and we can check it out.

    Did you disable those codes that show up? Disable every code dealing with bank 1 & 2 sensor 2. Also the catalyst efficiency codes. Uncheck ses light and choose no error reported.

    Yes, you have to uncheck the SES box.

    Some codes are permanent DTC's that won't just go away, they may stop coming up after a while though.
