[Shop-talk] Check engine light on a 2003 HD2500

[Frank Vantacich <rustymetal@sbcglobal.net>]

I have a 2003 Chevy Silverado HD2500 Duramax dieselwith an intermittent Check
Engine light on. The code is a P0380B and refers to the glow plug feedback
circuit. I was wondering if any one out there has run in to this problem?  I
believe the problem should be with a glow plug, harness or Controller and
would 
like to narrow it down. The truck starts right up and runs great with
the check 
Engine light on.

Thanks for the help.
