2004 F150 5.4 3v Question

[92lxstang]

We have an 04 F150 with a 5.4L 3v in it at my shop and we are trying to get it to pass state inspection. We had to install a new battery in the truck so it cleared all the monitors. We have driven it over 150 miles and the Catalyst and Evap will not get complete. Do you have any tips on how to get this thing to pass those either one of those monitors?

Thanks,
Ryan

I know that in some of the late model vehicles there has to be a minimal amount of gas in the tank for everything to clear out fine.

Some times it's a number of starts too. (like 20).

We have taken it on short drives, long drives, multiple starts, etc. We have had the gas from anywhere between the light being on to 3/4 a tank. I just want to get it to clear at least one of those so I can get it out of my shop...

Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII 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 "OBDII Monitor Exercised" column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), 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 following drive cycle.

The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.

Drive Cycle Recommendations:

1. Most OBDII 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".



Catalyst 7. Drive in stop and go traffic conditions. Include five different constant cruise speeds, ranging from 40 to 72 Km/h (25 to 45 MPH) over a 10 minute period. Executes the Catalyst Monitor.

We finally got it to pass this morning. In all we put over 500 miles on it.
