I will pull the cover off in the next couple days and see what is going on in there.



My Daughters 2010 Durango was throwing the same code, some times in "rest position it would be a few degrees off , others it was clearly off..... we chased it for a month, the clock spring in the phaser broke.

one thing to keep in mind, the 5.7 VVT ,map has 9* degrees less retard then the 392 map., not sure if that would cause the release to open less and leave some oil in the chambers that would keep the phaser from returning to 0*........but I would think that once the engine is off the phaser would bleed out the excesses oil and return on it's own.


Dave I know HPTuners is a bit on the expensive side, and it most likely will not fix this issue for you, but the ability to play with the VVT system....is worth it, my 09 Ram , stock 5.7 long block and the 392 cam, WOW what a Different animal it is with just a simple trans tune, and then the night and day difference the VVT tuning has made. seriously hit their forum a lot of good threads on how the VVT can be played with.
