OBD-II Drive Cycle Description

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2003 Mercury Sable, 2003 Mercury Mountaineer, 2003 Mercury Marauder, 2003 Mercury Grand Marquis, and 2003 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

The following procedure is designed to execute and complete the OBD-II monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, perform OBD-II DRIVE CYCLE VEHICLE PREPARATION , then continue with the procedure described by the appropriate monitor. EVAP monitor will not activate if ambient air temperature outside is not 40-100°F (4-38°C), or vehicle is above 8000 feet. If DTC P1000 has to be cleared when ambient air temperature outside is not 40-100°F (4-38°C), or vehicle is above 8000 feet, PCM must detect these conditions once (twice on some models) before EVAP monitor can be "by-passed" and DTC P1000 will clear. Perform EVAP MONITOR "BY-PASS" PROCEDURE.

All OBD-II drive cycles must be performed using scan tool. Consult scan tool manufacturer's instruction manual for drive cycle procedure. Vehicle should be driven at steady speeds during cruise or acceleration to help complete OBD-II monitors. Operate engine throttle in a steady fashion to minimize time required for monitor completion. EVAP monitor only operates during first 30 minutes of engine run time. If performing EVAP monitor procedure, drive vehicle at a steady rate and at part throttle to minimize possible "fuel slosh".
