P1000 OBD-II Monitor Testing Incomplete.
Has anybody had this code popup? My CEL is on and this is the only thing that shows up and its not stored in faults. It will clear with the hand helt and come back the next day. The car is running fine. Is this some type of problem that involves some missing input or output from a sensor? Any help would be much app. Thanks Bubba

Its on all the time and no I havent unhooked the battery. I use the Preditor tuner to read and clear codes. Like I said, it doesnt store any faults, just this. I can clear the fault log and the CEL will go out and come back on the next day maybe after 30 miles of driving.

Like Spike said, that code shouldn't throw a CEL. Maybe drive it around for awhile and check it again without clearing the code. Does the Predator give you a "no additional fault codes found" or something similar.

The code means that the car hasn't executed all of its OBD monitors. As said before, this alone will not cause the CEL. Here is the drive cycle you need to do to clear it if you want to. http://www.obdii.com/drivecycleford.html
If it doesn't go away after awhile you may have a problem with something that is causing the ECM/PCM to stay in open loop.This open loop creates a state where no diagnostic tests can be preformed.
A shorted o2 sensor or coolant sensor , or a stuck open thermostat can keep it in open loop.
I think the code is really there to keep ppl from clearing emmision codes right before an inspection.
