Hello and thanks for your question in the autoaid Community.
This fault Code means: CATALYST TEMPERATURE SENSOR CIRCUIT RANGE/PERFORMANCE BANK 1 SENSOR 1
By these Code, the Problem comes from the Sensor and this should be replaced.
Look in the Is values if you could see the Sensor datas and then Plug off the Plug from this Sensor and Look if the values take shown other measure, Look also if the shown temperature is logical, you also could measure the wires from the ecu to this Sensor. But in the Most Times the Sensor is faulty.
