and...as far as DTC codes, in many cases its not 1 part thats called out but many. i was getting that p1153 code a while back and the possibilities were close to endless on that one. Believe it or not, since i went off-roading with longshot...that code has yet to pop-up agn...and its been almost a month.
glad i didnt spend money on any parts.
2 pcms??? ...all i can think is why? the only way that makes sense to me is if one were to be responsible for certain data and the other was for another category of data. why would you need 2pcms, if one dont work right the other is just gonna thor things off....maybe thats a question for ford, or mike rowe lol.
interesting thread...

Maybe you had some soot that was messing up the sensor and you either burned it off climbing up those hills or shook it off when you fell back down.
I think the 2 pcms might be for either the two settings (tow and regular) or one for the engine and one for the tranny. Still an interesting question.
