Hello.

I have an 09 Journey R/T, FWD vehicle. Yesterday while I was driving, I floored the pedal to make it through a light that was about to change. Just as I did that, both my CEL & traction control lights came on. Car would no longer downshift. Got home, did the key thing to check for codes. Came up with P0344.
My husband changed the camshaft sensor, took it for a test drive, and when he went to step on it, CEL & traction control light came on again. Came home, same P0344 code. Changed the crankshaft sensor. Still getting the P0344 code.

Any other ideas as what it could be? Checked all the wiring and it's fine. TIA!

 

I have the same exact thing happened to my wife's 2009 with the 3.5 liter. did you find the problem.
