That is a lean code for bank 1 sensor 1. The code doesn't mean the sensor is bad, it means it's not switching and it's staying lean. The 1st thing to do would be to test the sensor to see if it's capable of switching and in the correct amount of time. Depending on the results would determine where you go next........
