Question: I thought P0410 and P1411 meant implausible signals from the bank 1 and bank 2 oxygen sensors. Once the car starts, doesn't the alternator provide sufficient voltage for the O2 sensors to do their jobs. And if the sensors are doing their jobs, why the CEL? In my car, it was a vacuum leak that triggered the light each time the SAI system was ready to test and the SAI pump turned off.
