I'm leaving this forum and have deleted all my work in this thread.

 

If the problems have corrected, then the Amigo's pack up and leave.
Problem comes back - Amigo's come back.
You probably have a sensor which has marginal output.
Move the sensor closer to the signal source.

 

Can you be more specific on exactly what you mean here and where?

 

Let us know if it comes back. I'd be interested in knowing. Perhaps the previous owner had a tech scan for the codes and replaced the sensor accordingly, but did not have them clear the codes.

I know the Amigo comes with a code from when they test it before shipping, but that's a logged ground fault I believe.

Curious.

Yes. It's the logged fault/code that comes with the unit.

Well, that's great news! Saves you the time from having to do the fix.
