The P1000 code in your Ford usually means that the vehicle’s OBD system hasn’t completed its readiness checks after a battery reset, a diagnostic tool use, or simply disconnecting the battery. While the P1000 code doesn’t point to any specific problem, it will prevent your vehicle from passing an emissions test until the system completes its cycle.

Here’s how you can fix it:

1. Drive cycle completion: The fastest way to clear this code is by completing a Ford-specific drive cycle. Follow these steps:
   

• Start the engine when cold. Let it idle for about 4-5 minutes with the air conditioning and rear defroster on.
  
• Accelerate to 45 mph under light throttle. Keep a steady speed for about 5 minutes.
  
• Decelerate without braking (coasting down) to 0 mph. Then, let the engine idle for another 5 minutes.
  

      2. Check your vehicle’s readiness monitors: After completing the drive cycle, use a scan tool to check if the monitors are ready. If they are, the P1000 code should disappear, and you’ll be ready for an inspection.

This process can take a few tries, so be patient. Keep in mind that as long as you don’t disconnect the battery again, the system should eventually reset itself.
