Default P0340 code

HAVE A 03 DAKOTA 4.7L, CODE POPS UP TWICE, I CANGED THE SENSORS CRANK AND CAM, NEW TIMING AND GEARS, NEW INJECTORS, NEW EVERYTHING, COILS AND ALL. CHANGED PLUGS FOR CAM. THE PLUG CAMEVBLACK WIRE WHITE WIRE AND GREEN WIRE, BLACK AND GREEN STRIPE WIRE TO THE WHITE CENTER, THE BLACK WIRE ON PLUG TO THE BROWN AND WHITE TRACE WIRE,. THE CRANK TOO! THE GREEN AND WHITE TRACE WIRE TO THE Green and white from PLUG to black so on, I know there are two reluctor wheels for cam. I have both called dealer and believe I have right one in there. I'm getting two little pops on CRANK, it takes a little then fires up and cam sensor keeps popping up twice. Anyone give a hand here?

Cam sensor "A" problem. Don't know how many you have in there, but, if you changed the sensor, and nothing changed, time to check the wiring. Might just be a bad/dirty connection at either end of the wiring.

Has the cam tone ring been changed at all that you are aware of??

What is the PCM seeing from the cam sensor??

yes I know there's two of these I have both, I changed timing but the marks aren't lined up on left and right sprocket gear, Must have jumped, gave to reset timing on it. Maybe the issue, They say the cobalt links are just reference like for the idler windows and the single on each gear for cam. But these are magnetic, may have something to do with picking up the cam sensor, I'm assuming. You'd think a chains a chain but the marks may be magnetic to pick it up for the ecm

Think you need to correct your timing there first, see if that doesn't solve it.
