A P1000 means that the Electronic Engine Control system hasn't finished testing itself.
It has "monitors" such as for the EGR, O2s, EVAP systems etc. When the PCM finishes testing all the monitors it will erase the code.
You will get a P1000 if the battery has been disconnected, the PCM has been disconnected or if a problem has been fixed and a trouble code erased but it hasnt been driven enough to complete the monitors.
Usually just driving it some more will clear the code. You cant manually clear it.
