replacing the Angolar speed sensor f430

My car has been throwing a CEL every now and then code seems to be p0014B something about cam timing, after some research i found a post with a scuderia showing similar behavior he replaced the phase sensors and the angolar speed sensor and this specific code went away. i have already change the phase sensors but not sure where the RH angolar speed sensor is or what the replacement procedure is. Has anyone done this before? any help will be appreciated
the diagrams from ricambi dont really show where its located
