P1000 won't clear
Took my Ex in for inspection they said the drive cycle is not complete. I haven't reset the computer in at least 6 months and I've done a couple thousand miles since then both on city and on the highway. Anytime I hook up the Bluetooth obd2 reader the code is always there. Always. Even at previous inspections and I didn't have an issue. And advice on what to start with?

You could try completing the drive cycle... very specific procedure outlined there.

In hindsight I should have checked with my obd2 tool first but hindsight is 20/20. It's just funny that the p1000 code has always been there since I got the Ex and I never had an issue passing inspection. I haven't reset the computer in months and I've done lots of driving at many different speeds but I don't think any have been longer then 2 hours.
Maybe I need to take a road trip....

I just came across this thread https://www.ford-trucks.com/forums/1...not-ready.html and this one https://www.ford-trucks.com/forums/3...s-testing.html.
I checked my receipt, it says 0 - 8500 for the weight class. Last years says 8500 - 10000.
Consider this mystery solved.

You wan to explain how replacing a part is going to "cure" a problem where the testing station made a mistake and put the wrong information into their computer causing the "test" to fail for non-existent sensors?

Follow up: I took it back for reinspection and it passed in the 8500 - 10000 category.

brannman, I see your from Washington, maybe your Ex is a California emissions compliant and has O2 sensors after the catalytic converter as well?

Didie, I chased a p1000 Drive cycle code error for quite a while. The only thing that had not been looked at/serviced was the IAC valve. I pulled it - full of carbon. Bench tested - no movement. Replaced with new one - p1000 cleared with a 5mi drive.
I read your "O2 not ready post" and presumed you would figure out that these are artifacts in the programming (OBDI vs OBDII) due to not having post-cat sensors. No, I have a Federal truck, not a CA truck - one upstream sensor on each downpipe before the cat.

Did you have any other codes accompanying the p1000? I have none. Also, all other tests (that the vehicle is equipped with) show complete.
I monitored the live data using forscan and the iac valve seems to be functioning.
What year is your ex?

The fastest way rid yourself of a P1000 code is with the Ford Motors Drive Cycle these steps cover many Fords
1) fuel tank has to be 15 to 85% fuel with the vehicle sitting 8 hours
2) start and idle for 4 minutes
3) idle in drive for 1 minute
4) drive towards an empty street or highway and accelerate slowly to 45, but stay in 2 gear for 5 seconds when accelerating to 45.
5) maintain 45 mph for 30 seconds, the slow to a stop (engine always running in drive cycle)
6) idle in drive 1 minute again
7) drive at 25 mph and drive for 15 minutes at speeds between 15-35 mph. with that time stop at least 5 times and have at least 3 periods of steady speed for 90 second duration's.
8) drive the vehicle between 45-60 mph for 8 minutes, maintaining it for at least 5 minutes and then 8 minutes again between 45-60 mph
9) stop in park idol for 1 minute.
If the P1000 code still exist you have an pollution problem, and getting poor fuel mileage. A P1000 code will come up every time you disconnect the battery, replace something or clear trouble codes with a scan tool, diving the vehicle will reteach your brain and the code goes away. I'm to old for this but then my battery dies along with the brain, life-cycle's vicious, but not if you buy a X-Tool . . .
