I'm getting P0138 Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2). Is that the sensor behind the cat and is it just a bad sensor or something more?

took it out to cut and weld the downpipe about a month ago. The CEL showed up about a week ago and then didn't pop up again until today but it came up again after I cleared it.
