If you've recently had it out then it shouldn't be a problem. The issues are difficulty in removal, and the sensor pulling out the threads on the collar.
I use my torque app to monitor the lambda readouts, and recently spotted a fault on the post cat lambda. It turned out to be a poor connection on the plug. Separated the plug and socket, cleaned the terminals and the lambda started working again. So worth trying that before removing/swapping the sensor.
