DD15 Injector Controller High Pressure Fault

Good day,

I have a 2010 Cascadia, DD15 Engine w/ 1.18 million miles. The complete fuel system was changed at 700k mile; fuel pump, rails, injectors.

I was driving yesterday and got an Amber CEL and Solid Amber Engine light. I pulled off to the side and the engine was idling rough and at 800 RPM, normally my truck idle speed is 600 RPM.

I turned off the engine, inspected for the unusual, etc.. and found nothing out of the normal. When I started the engine again the faults were gone and today am driving w/ no problems.

Can this just be a glitch or should I start to concern myself with the high-pressure fuel pump starting to go bad?

I failed to get the code, cause when I turned off the engine and turned back on the codes cleared.

Any help, advice would be appreciated. Fern

 

I figured as much, but worth the asking. I'll get back as soon as possible.
