Default CEL: P0011 code help

Hi, I own an 08 WRX that threw a P0011 code about 25 miles ago.
If this code is being caused by a malfunctioning camshaft position sensor, is the car responding to that and changing how it runs (is it fine to drive?), or is it just reading the discrepancy and throwing the error code?
The car was upgraded to a VF-52 turbo with a Torqued Performance open source 2.52 tune about 700 miles ago at 106,9xx miles. It also had the timing belt done at the same time. When they did the timing belt the mechanic noted that it had jumped 2 positions (teeth?).
So far I have logged the camshaft advance angle which showed bank 1 reaching angles of up to 50 while bank 2 usually maxed out at 40. We swapped the AVCS solenoids between the banks and logged data with the same results. We also tested the solenoids with a 9v battery and noted that they moved the same distance and didn't seem to be jammed. We also checked the AVCS banjo bolts for obstructions or clogged filters, but it turned out that they had already been removed. At this point, it appears that there is something preventing the camshafts from advancing correctly other than the solenoids, or that the camshaft position sensor is malfunctioning on bank 1. I am in the process of switching the left and right camshaft position sensors to see if that isolates the problem, but it is a pain to get to those sensors. does anyone have advice on removing/ replacing them? Also any other suggestions on what to do moving forward would be appreciated.
Thanks

Also does anyone have advice on removing the camshaft position sensors on the 08 wrx/ other similar ej255 cars? it appears that I can remove the bolts holding them in place, but there is something (maybe the head) over the sensors blocking them from being pulled out all the way.
