How to Read Ford Scan-Tool Readiness
You do not need a particular brand. You do need to read more than the code list: MIL, pending vs stored vs permanent, monitors, and freeze-frame.
Keep the types distinct
- MIL / check engine lamp — commanded on or off. P1000 can exist with MIL off.
- Stored DTC — matured fault memory.
- Pending DTC — a concern that has not necessarily matured.
- Permanent DTC — a fault category that does not clear the same way as a simple erase; not the same as a readiness bit.
- Readiness monitors — test-complete flags.
- Freeze-frame — snapshot of conditions when a fault was recorded.

Ford OBD Status
Illustrative screen — not a live reading from your vehicle.
- MILOFF
- P1000PRESENT
- CATREADY
- EVAPNOT READY
- O2SREADY
- FUELREADY
P1000 can be present while the MIL is off. Read the monitors, not only the code list.
No required brand
Generic OBD-II tools can show readiness. Enhanced Ford data may add PID names. Neither “clears P1000 permanently” by erasing codes.
