CODE 2AAF, just replaced low pressure fuel sensor

Had a code for a while for my low pressure fuel sensor finally got around to replacing it and now the car throws a code 2AAF for fuel pump plausibility, I understand sometimes taking out the sensor without disconnecting the battery can trigger this but I have cleared it a few times now and it has still came back, how long is normal for it stay? It has been maybe an hour.

There is an upgraded sensor that stops this shadow code. The original sensor is not as good.
