additional codes of p1126 and p1124 with no further info.
what is the location of the sensor that needs replacing

Bank 2, Sensor 1 would be on the driver's side before the catalytic converter (pre-cat) on a US/left hand drive car. Before you replace the sensor, ensure that the plug (follow the wires from the sensor to find it) is securely attached, as my Boxster threw an oxygen sensor code and it turned out that the pins in the plug had backed out. I pushed them back into place and, voila, no more sensor code!
