As far as the problem, it looks like you are on the right track. It deals with the CKP circuit A. What I did is this. First, I attached the wiring schematic for the entire powertrain control circuit. I highlighted the wires from the CKP and CMP to make it easier for you to trace. Additionally, I highlighted the CKP and CMP sensor in the schematic.
Next, I included the diagnostics related to the code. They follow the schematics and are specific to the P0335.
Here is a link you may find helpful when testing wiring:
I hope this helps. Let me know what you find or if you have other questions.
See pics below. Note: The schematics were a few pages long. I had to cut each page in half to make them readable for you. I did overlap them so you can follow from one to the next. Also, pic 7 starts the diagnostics. Pics 4 and 6 contain the sensors in question.
