Hello! That code indicates that the sensor is not heating up fast enough. If all the fuses are good, then the sensor itself is probably bad (it has an internal heater). Bank 1 indicates on this motor, that its on the drivers side (as opposed to Bank 2, which would be the passenger side on this motor). Sensor 2 is after the catalytic converter (Sensor 1 is just before the catalyst). So the code refers to the sensor thats just behind the converter on the drivers side.
Hope this helps and PLEASE let me know if you need additional help!
