P1000 is a readiness code. It's intended to demonstrate that a lack of error codes logged correlates with the PCM having checked all parameters. In other words, after codes have been cleared, the PCM needs to see a certain pattern of driving called a "cycle" that allows it to exercise all the testable parameters and sensors. The idea is to prevent people from erasing the codes and then rushing to an emissions test with no codes in memory. P1000 is the PCM telling the inspector that "Yes, there's no codes but I haven't checked everything yet..."
Simply driving 200kms may not be enough to fulfill this requirement. You need to drive the car in a way that satisfies the Ford OBD-II driving cycle, seen here:

I am so glad I don't live in a state where emission testing is required... what a freaking joke... New cars are such that most will trigger an engine light if/when there is an issue with the emission system. Most car owners will get their vehicles fixed.
I seriously doubt the remaining 0.02% that install cat-less mid pipes or disregard the engine light are doing much, if any, harm to the environment

i'm jealous, and yeah i agree, as long as cars come stock with cats, 98% will leave them on

when clearing codes at work i have noticed, we tend to see the p1000 code come up when a scan tool has been used, and then unplugged without backing out of the program and shutting the scanner off first. you may try to go to a shop you know ask them to scan the car and if no other codes are there, ask them to first exit out of the program shut the programmer off, then turn off car and disconnect scanner. i will say that in most cars the p1000 code by itself won't usually turn the light on
I am assuming the OP is in CAlifornia since he keeps calling it a smog check, and IIRC we are the only state that calls it that. If that is the case, a present P1000 code is an immediate failure.
OP: what monitors have not run yet?

The P1000 is not really an error code. It means that some monitors have not completed. There are valid reasons for some monitors to remain pending. Especially during cold weather or say above 5,000 feet.
I was not aware that any state would not pass the car where the only code is P1000 AND no MIL present.

+1, The reason the code is still coming up is because you may be having a faulty sensor or something else with the computer is going wrong.
Friend had a code, cleared it with his scanner several times on his truck and had this code for over 2 weeks. What got it to go away? He simply cleared the code, turned the scanner off and disconnected the battery for a half hour(lunch). Then we reconnected the battery, and followed the drive cycle exactly, I mean exactly. Country roads are really nice for this. You can't just clear the codes and go in some cases, I would reset the PCM as well and retry.
As far as Codes vs. Smog, I know in Cal you are allowed to have one code when you go in for smog.
