Q: Are the variable valve timing solenoid and the camshaft sensor the same?

My care has miss fire issues, car is shaking as well with the check egine light sitting on and some times blinking on/off. Codes like p0017, p0036, p0300, p0128, p0140, p0141by pepboys and p0017/p0036 by another machanic. Pepboys replaced the variable valve timing soleniod and put in not engine light may come back on becase a camshaft may be need. Left with the same problem he told me to bring it back so he could put it on the scanner on next week Thursday because his scanner is broke. It was shaking worser with ongoing worser shakes when miss firing I could not pick up any speed. When I asked if it would futher damage the car by driving it he said it was ok to drive. I decided to take it to another pepboys location so they could scan it and finish the wk there. They told me he did not diagnose it right and he did another diagnostic and said it was nothing wrong with my camshaft but told me a lot of other stuff was wrong with it. I dont think either one of them know.
