vtps not working
 

I've been running my 1.6 with a vtps out of a auto 1.6 for about 2 months successfully. Now when I go to tunerstudio, the vtps is not working all of the sudden. I unplugged it and made sure all the soldered connections are still soldered. They look perfect. What could make it stop working? I had this same problems when I initially wired it last winter, it wouldnt read until one day it started reading again...wtf

I resolded everything and it works again...weird they looked fine
