I got the same error while upgrading Ultimaker2 to 2+. Homing like this, isn't it? In my case, when I replaced feeder motor, I crunched X sensor blue wires between motor and wall. I stared the other side of wall and hadn't noticed that. As most weirest point, I couldn't notice that first because I checked X switch is working properly with tester. Pins on PCB is shorten only when switch is clicked. But I found homing process is changed when X sensor is connected/disconnected to PCB (Take care to turn off main power switch before hitting left wall!). Then I found cable is damaged. I cut crushed part of wires, soldered and covered with heat shrinkable tubes. Then everything worked well! I cannot confirm you have a same situation but if you find any damage on X sensor cable, I recommend you to replace it even though it looks fine.
