P 0678 codes

So I have all of the codes for the drivers side glow plug circuit and I purchased an aftermarket UVC gasket and reset all codes but the service engine light still comes on and all of the same codes are being displayed. I have checked to make sure the plug is in good shape and all looks good. Any ideas what else could be tripping these codes? I am really stumped on this one. When I took the valve cover off the old plug was disconnected about 1/8 of an inch so I just knew that was the problem and it is too much of a pain to have to take the cover off again.

It is likely the GPCM if you are getting the codes for the entire driver's side.
