Code troubles

I just happened to scan my truck through my scangauge to check for any other codes except the # 2 glow plug which has caused my CEL to be on for the past few weeks. I found these codes. Can somebody tell me what they are??
P0373 Timing Reference High Resolution Signal A Intermittent/Erratic Pulses
C301E ????? I cant find this one
thanks again fellas
I think the "P" prefix stands for "power train" and the "C" stands for "Chassis". The list that I have attached is just for the power train DTC.
Here is a link to some chassis codes that I found online.
