I have a 2 cam 2.0L 4 cyl 3 wire cam position sensor. I am getting scan code P0340.
Expert:  Ironmike replied 11 months ago.

how does the vehicle run, rough? do you have access to a scanner that shows live data? can you verify engine timing? we need to make sure the timing chain has not jumped/ valve timing is not off.
