DPF sensor - reset?

The engine light came on a couple of weeks ago and I replaced the DPF sensor, which was the error code read out from my scanner. After replacement, the car was fine for a week or so. But then, the engine light came on again and I get the same error code that the DPF sensor is out of its range.
Does the new sensor need any re-calibration or lean-in process? If I erase the code, it will come back.
Car does not go into limp mode, it is running fine.
I would appreciate any ideas!
