my 2008 flhtcu keeps throwing codes at me when I ride they are "P1510-EFI LIMITED PERFORMANCE MODE,P2127-TGS LOW/OPEN,P2138-TGS CORRELATION ERROR,PO-562 LOW BATT VOLTAGE.I reset codes bike works fine for awhile then codes pop up again. I have checked battery and then changed battery. Still have same problem, my volt gauge reads over 14 volts when running but doesn't seem to charge battery fully. Iwas looking for some insight to problem before going to shop,any help would be greatly appreciated.

 

Did you clean the TCA connection behind the air cleaner? Look for tech tip bulletin TT418A

 

Here's the bulletin
