P1000 - On Board Diagnostic (OBD) System Readiness Test Not Complete

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P1000 - ON BOARD DIAGNOSTIC (OBD) SYSTEM READINESS TEST NOT COMPLETE

Description:  The OBD monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.
Possible Causes: 
  • The vehicle is new from the factory.
  • Battery or PCM had recently been disconnected.
  • An OBD monitor failure occurred before completion of an OBD drive cycle.
  • PCM DTCs have recently been cleared with a diagnostic tool.
  • PTO circuit is shorted to VPWR or B+ or PTO is on during testing.
Diagnostic Aids:  The Ford P1000 inspection/maintenance (I/M) readiness function is part of the PCM strategy. A battery disconnection or clearing codes using a diagnostic tool results in the various I/M readiness bits being set to a "not ready" condition. As each non-continuous OBD monitor completes a full diagnostic check, the I/M readiness bit associated with that monitor is set to a "ready" condition. This may take 1 or 2 drive cycles based on whether malfunctions are detected or not. The readiness bits for comprehensive component monitoring, misfire and fuel system monitoring are considered complete once all the non-continuous monitors are evaluated. Because the EVAP system monitor requires certain ambient conditions to run, special logic can bypass the monitor for purpose of clearing the EVAP system I/M readiness bit due to the continued presence of these extreme conditions.
NOTE: P1000 does not need to be cleared from the PCM except to pass an I/M test.
