Misfire Monitor Repair Verification Drive Cycle 

1. For applications with the Fuel Level Input (FLI) circuit to the PCM (terminal No. 12), check the fuel 

gauge and the FLI PID on the scan tool (if available). The Misfire Monitor can only be tested if the fuel 
gauge reads above one quarter full or the FLI PID is above 15 percent (percentage fuel tank fill).  

2. Start the engine and drive the vehicle to a location where speeds can reach 55 to 60 mph and coast down 

to 40 mph without traffic interference.  

3. Accelerate at wide-open throttle to allow vehicle to shift at red-line (if equipped with a tachometer). 

Immediately return to normal speed limits.  

4. Perform the following drive procedure three consecutive times. Accelerate on highway to 60 mph. 

Maintain speed for 30 seconds. Coast down with foot off the accelerator pedal from 60 mph to 40 mph.  

5. Rerun Quick Test. See QUICK TEST in appropriate SELF-DIAGNOSTICS article.  

Secondary Air Monitor Repair Verification Drive Cycle 

1. Refer to and complete the Vehicle Application Preparation For OBD-II Drive Cycle before initiating the 

following repair verification steps. See VEHICLE PREPARATION FOR OBD-II OR MONITOR 
REPAIR VERIFICATION DRIVE CYCLE 
.  

2. Start the engine and proceed through the entire OBD-II Drive Cycle until the Secondary Air Monitor 

shows the On-Board Readiness Menu completion status on the scan tool.  

3. If the entire OBD-II Drive Cycle has been performed and the Secondary Air Monitor check has not 

completed, rerun Quick Test. See QUICK TEST in appropriate SELF-DIAGNOSTICS article.

Introduction 

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, follow steps 1 through 4, then 
continue with the step described by the appropriate monitor found under the "OBD-II Monitor Exercised" 
column. See Drive Cycle Procedures . When the ambient air temperature is outside 40 to 100°F (4.4 to 37.8°
C), or the altitude is above 8000 feet (2438 meters), the EVAP monitor will not run. If the P1000 code must be 
cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP 
monitor can be "bypassed" and the P1000 cleared. The EVAP "bypassing" procedure is described in the drive 
cycle. The OBD-II Drive Cycle will be performed using a scan tool. Consult the instruction manual for each 
described function.  

Drive Cycle Recommendations 

1. Most OBD-II monitors will complete more readily using a "steady foot" driving style during cruise or 

acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for 
monitor completion.

2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.  

3. The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When 

executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to 
minimize "fuel slosh".

2003-2004 6.0L DIESEL 

Description 

Primary function of drive cycle procedure is to clear DTC P1000 and to satisfy specifications for SAE J1979. 
Each OBD-II monitor must run during drive cycle. If drive cycle has been completed and DTC P1000 is not 
cleared, repeat entire drive cycle. If a particular step is interrupted, repeat drive mode. If drive cycle is 
interrupted with a key-off, only drive modes that were incomplete must be run.  

Performing Drive Cycle 

1. Turn ignition on, but do not crank engine until WAIT TO START indicator turns off, or 10 seconds has 

passed (whichever is greater).  

2. Start engine. Allow engine to idle with transmission in Park or Neutral for 40 seconds.  

3. The following conditions must be followed to run certain OBD-II monitors that require engine to be 

under a load. Accelerate steadily to 3rd gear (A/T) or 4th gear (M/T) and keep engine speed at 1500 RPM 
for 3 seconds. Accelerate steadily from 35 MPH to 65 MPH in about 15 seconds (A/T) or 11 seconds 
minimum (M/T). Repeat this procedure 3 times while maintaining conditions set in this step. Before 
proceeding, turn all accessories off and disengage TOW/HAUL.  

4. Before continuing, using scan tool, select EOT PID from PID/DATA MONITOR & RECORD menu. 

Ensure EOT PID value is more than 140°F (60°C). Allow engine to idle for 20 seconds in Park or 
Neutral. Turn ignition off. Start engine and allow engine to idle for 40 seconds in Park or Neutral. Repeat 
QUICK TEST in appropriate SELF-DIAGNOSTICS article. Drive cycle is complete.  

5. If DTC P1000 is present after performing drive cycle, repeat step 3 maintaining a minimum MFDES PID 

value of 35 milligrams/stroke with engine speed at more than 2000 RPM for 11 seconds. Also, maintain a 
minimum MFDES of 30 milligrams/stroke with engine speed at more than 2800 RPM for at least 6 
seconds. Repeat step 4 . MFDES PID value must remain less than 12 milligrams/stroke for 11 seconds.  

1996-2004 7.3L DIESEL 

Description 

Primary function of drive cycle procedure is to clear DTC P1000 and to satisfy specifications for SAE J1979. 
Each OBD-II monitor must run during drive cycle. If drive cycle has been completed and DTC P1000 is not 
cleared, repeat entire drive cycle. If a particular step is interrupted, repeat drive mode. If drive cycle is 
interrupted with a key-off, only drive modes that were incomplete must be run.  

Performing Drive Cycle 

1. Turn ignition on, but do not crank engine until WAIT TO START indicator turns off, or 10 seconds has 

passed (whichever is greater).  

NOTE:

Rough road conditions may prevent certain steady state conditions and steady 
accelerations from validating the transmission and load-related monitors. On 
models with Power Take-Off (PTO), disengage PTO system before performing 
drive cycle.
