I have recently had the same problem with my passport 2. They thought is was a sensor. That wasn't the problem. It has been in the shop for over a month. Mine is 4 years old and I use it for retreats and sewing days. I have an older Phaff that I usually sew on at home. I like the built in walking foot. I was going to trade up to the passport 3 but now I am thinking that might not be a smart thing to do.
