Drive Cycle Recommendations
NOTE: This procedure was created to clear the Ford P1000, inspection and maintenance (I/M) readiness code. When the ambient air temperature is below 40°F (4.4°C) or above 100°F (37.8°C), or the altitude is above 8,000 feet (2,438 meters), the EVAP monitor will not run. If the P1000 must be cleared in these conditions, the powertrain control module (PCM) must detect them once (twice on some applications) before the EVAP monitor can be bypassed and the P1000 cleared.
NOTE: Use a worldwide diagnostic system (418-F224), a New Generation STAR tester (418-F052), or equivalent.
Drive Cycle Preparation
NOTE: For best results, follow each of the following steps as accurately as possible.
NOTE: This step bypasses the engine soak timer and resets OBD II monitor status.
Preparation for Monitor Entry
It is important to strictly observe posted speed limits and pay close attention to driving conditions while running through the drive cycle that follows.
NOTE: This step allows engine warm-up and provides intake air temperature (IAT) input to the PCM.
NOTE: This step executes the heated oxygen sensor (HO2S) monitor.
NOTE: This executes the EVAP monitor if IAT is above 40°F (4.4°C) and below 100°F (37.8°C).
NOTE: To initiate the monitor, TP MODE should equal PT, EVAPDC must be greater than 75%, and FLI must be between 15 and 85%.
NOTE: Be sure to avoid sharp turns and hills.
NOTE: This step executes the ISC portion of the Secondary Air/CCM.
Pending Code and EVAP Monitor Bypass Check
NOTE: This determines if a pending code is preventing the clearing of P1000.
NOTE: If the EVAP monitor is not complete and IAT was below 40°F (4.4°C) or above 100°F (37.8°C) temperature range in Step 8, or the altitude is above 8,000 feet (2,438 meters), the EVAP Monitor Bypass (Step 13) must be carried out.
EVAP Monitor Bypass
NOTE: This allows the bypass counter to increment to two.
NOTE: Do not repeat Step 4.
