Hi Dave, One other thing I forgot to mention in my post was that on my van once the reediness test has been satisfied (p1000 code cleared) the whole thing starts all over if I clear my codes again (P1000 code will be back). I can only speak for my particular set up '05 6.0PSD with an Edge Insight for monitoring, code reading and clearing. My Edge Insight is the one with just gauges, no tunes. I'm not sure if other code readers are different in how they clear codes. In a nut shell I'm suggesting that when you complete your drive routine I would be careful not to the hit the clear codes button on the reader your using.
The main reason I seem to have to clear codes is that I seem to remove the airbox and inter-cooler plumbing a lot to get access to the front of the engine. To do that I need disconnect the Mass Air Sensor and inevitably will need to turn on the ignition for some reason or forget to plug it back in and HELLO need to clear the code.
Just for others knowledge, here in El Paso County of Colorado the only vehicle that gets smog tested are diesels. However, it's mainly a soot test. They strap it to a huge dyno (think big enough for a school bus), go to wide open throttle and you have so many seconds for the smoke to clear. Last time I went I had a P1000 code and it passed so I assume it's only the hard codes they worry about.
Anyway, let us know how it goes
