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

2005 Ford Econoline E150, Van Cargo, 5.4 LSECTION DTC P1000: On Board Diagnostic (OBD) System Readiness Test Not Complete
P1000 - ON BOARD DIAGNOSTIC (OBD) SYSTEM READINESS TEST NOT COMPLETE

Description:  The OBD monitors are carried out 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 powertrain control module (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 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 have been evaluated. Because the EVAP system monitor requires certain ambient conditions to run, special logic can bypass the monitor for the purpose of clearing the EVAP system I/M readiness bit, due to continued presence of these extreme conditions.
NOTE: P1000 does not need to be cleared from the PCM except to pass an I/M test.
