Code P1000 2002 Ford F150 Description

The P1000 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates that the On Board Diagnostic (OBD) system readiness test has not been completed. This means that the vehicle's computer has not finished checking all of its emissions control components and systems. In order for the OBD system to be fully functional and accurately monitor the vehicle's emissions, it needs to complete a series of self-tests. If the readiness test is not complete, it can prevent the vehicle from passing an emissions test, and it may also prevent the detection of other potential issues or malfunctions within the vehicle's systems.

Tech Notes for P1000 2002 Ford F150

This code just means that the Powertrain Control Module (PCM) didn't complete a full diagnosis cycle, and is set when the battery has been disconnected, codes have been cleared, or sometimes even when the vehicle has been towed. No scanner is necessary to clear the code, driving the vehicle for a few minutes (sometimes more) to complete the diagnosis cycle will clear the code. Clearing the code will reset the light unless other codes are present.
