I have a 2012 Rover with the codes p0341 and p0366 which are codes for the bank 1 intake and exhaust camshaft position sensors so I went into my scan tool and graphed the two sensors data. Both sensors go from reading accurate cam angle(based on data from bank 2) to dropping to zero and then back to accurate readings. I have an old lab scope which I used to check for inconsistent signals from the sensors but only saw matching patterns to bank 2. I also check resistance of the wiring to the ecu.
I should also not that the truck runs perfectly.
this could be the cam sensor wiring running too close to a secondary ignition source to a broken or damaged reluctor wheel on the cam, a loose connector at the pcm or the sensor.
If you only have the check engine light and no prolonged cranking or poor fuel usage check the routing of the wiring and connections. Reset the code then do the touch test. Touch along the wiring to the sensor without relocating it and see if the code sets. If its shorting, you will get the code.

Being wrong doesn't bother me, it's being right and not understanding why that does
My first thoughts are powers and grounds , both sensors will be supplied with powers and ground from the same section of sub harness so it looks like a wiring or connector issue.
