Yes, cam pos sensor codes and crank pos sensor codes are different. If my memory is correct, there are two crank position sensor, one is a "phase" sensor. One will be near the crank pulley and the other at the back of the engine. You also have several cam sensors. You have two cam sensors on the cover, if I remember correctly, and two located just past the rear timing cover for the variable valve timing control. I don't know if a 3-wire cranks sensor will drop in place of a 2-wire? I haven't done any JDM VQ swaps.
