Cam position sensor

I read the testing procedure listed for the e90 under tech articles. I am getting 5 volts on terminal 1, 0 for ground on terminal 2, and 12 volts on terminal 3 at sensor. The article states to use terminal 2 (middle) and move a wrench across and voltage should fluctuate between 5 & 0. This only happens on terminal 1. Actual voltage is 4.65 on both sensors so I assume they are fine? Or do I have a wiring issue?
Doing this test on 2010 535 xi but it is the same part #
