06 dodge ram 3500 5.9 diesel 4 wheel drive/engine code PO148/what does this mean

Question

what causes an engine code PO148 on an 06 dodge ram 3500/5.9 engine/diesel

Answer 1

P0148 High pressure common rail (HPCR) check sum

The set condition for this is a deviation between the fuel pressure set point and the actual fuel pressure , by means of the fuel pressure sensor. Low fuel pressure can cause this , air in the fuel lines or the fuel pressure sensor not reporting the actual pressure.  Is there any other code with this?
