Check the wires over and the connection. You might have pulled a wire loose from the plug.

What kind of sensor is it? It maybe faulty.

You could of loosely put the copnnection back on, and it held long enough to clear the code, then the connection came loose??? Also, did you put an aftermarlet sensor on, or an OEM sensor? Used or new?
