I have been getting a p063d code, generator voltage sensor high for the past day now and I keep clearing it and it just comes and goes. I also had to replace a bad drivers side battery today when my truck would not start. Anybody have any ideas what this could be or what I can do to try and diagnose it?

I got the same thing... the lightning bolt will come on and stay on then you shut the truck off and restarrt it and it is off but the check engine light is on. Clear codes and all goes away for a bit....

I clear mine and it just comes right back, but its just the lightening bolt no check engine light. My volt meter says about 12 volts and I get a check gauges light on the dash, but sometimes I'll have 14 volts and just the lightening bolt. I tried unhooking the battery to reset everything but that didn't help. It seems like I have only been having this problem after I removed the PPE programmer and dowloaded the Smarty.
