p1682 I just changed the alternator the other day and then I checked for codes last night and to my surprise I had that code. I did not have the code before replacing the alternator. I cleared it with the Smarty last night and haven't have a chance to rescan since I drove it to work today. Is that normal to throw that code after you install a new alt? I unhooked both batteries when I changed the alt.

p1682, Charging Voltage Too Low. Batteries go low with the old Alternator?

 

I had batteries tested at Advance Auto I had then test the alt and my batteries were good they said. I'll check codes again tonight and see....

not sure if this matters either but my display for my voltage is a little above 14 on my gauge cluster.

 

I would just check the code occasionally. It was most likely generated when the alternator was swapped. If it doesn't come back, and the system charges, don't worry about it.

 

Kinda what I was hoping that is was just from swapping it out. I'll be checking it tonight after work.

well had it again today, it seems as if it only comes on after it sits for a while. I checked it when I got home from work and had the code, along with a vehicle speed sensor code. I cleared them, went and drove and no codes. Seems like they only happen after it sits for hours or goes into high idle.
