Hey guys, I did a bit of searching but the most I could find through google was stuff on the mazda and ranger forums, and when I searched here I couldn't find a whole lot either... My engine threw up a service engine light which is solid (its not blinking) and I hooked up my programmer to check DTCs. I got P1000, P2004, and P2006... It seems the first one is related to the OBDII Monitoring Test being incomplete. The second and third ones I think are related, but it has to with "Variable tunable control system," which is something to do with the Mass Air Flow sensor or the butterfly valve? I asked Ford if its safe to drive, they told me as long as its a solid light Im good, but if it starts to flash I need to pull over... I put a lot of miles on my truck daily... I just had 40K mile checkup, oil change, tire rotation done by Ford two days ago. What gives? Any ideas what these mean? Thanks in advance!

 

The p1000 just means that the PCM has been reset and it has not been driven far enough to establish it's new parameters. Happens when it is reflashed or the battery is disconnected.

For the p2004 and p2006, I assume you did a search. I did and came up with these in case you didn't. There are many others.

Ok well it wound up being that some line coming from the steering fluid box (I can't remember crap right now) was hitting the rotating arm on the air intake thing behind the motor and that made it burn out early. Had to replaceit. The put a longer line in so it wouldn't push againt it.
