Re: SES code P0147
bank 1 sensor 1 is the first sensor on your driver side. bank 2, sensor 1 is the front pass side. bank 1 sensor 2 should be the precat sensor. and bank 1 sensor 3 should be the last sensor. o2 simms or deletion through edit should take care of it. If you don't have cats, it's normal for it to be set off, b/c the sensor is reading improper heating parameters.
