continuous codes
 

I was wondering if anyoune can help me figure out why im getting so many codes. Im driving a 2001. I was getting the p0122, p0463 and p1693. I reset using the batery disconect and pedal calibration. After an hour of driving and no problems, I chacked for additional codes and recieved the p1693 and p1389. these all seem to be electrical in nature but I cant figure out what the source is.:s::s: Any help would be greatly appreciated
thanks in advance.
