Safc 2 problem

[gstjoker]

Any guess how on my safc where the first thing it reads is I think Karman when you're on the monitoring screen? Mine is only reading 3 hz and it's not moving at all. It use to work just fine before and I didn't mess with anything near that area except hooked up my rewire kit for the fuel pump. It was after that, that I noticed it was only reading 3 hz. If the connection was loose, would it even read at all? I hate this car, it's like one problem after another.
