P1280 code - ICP range low
I have been getting a check engine light occasionally the last week or two when I first start the truck and goes out after 30 sec to a minute. This has happened maybe 3 times now. Pulled the codes and have a P1280 stored in the computer. ICP (Injection Control Pressure Sensor) out of range low. Anyone run into this fault and know what the probable cause may be?

Giving it some thought, the truck has been idling a little rough and surging ever so slightly when crawling down 4 wheel drive roads. Today I noticed it surging slightly at road speed. I have been hauling a lot of fuel wood early this summer on some very nasty roads and lately I've been chasing elk on some pretty nasty roads. I wonder if I haven't loosened up a resistor in my 16.2k mod. I am going to pull it off and put it back to stock tonight and see if things don't improve in the idle/low speed crawl area - that may be the issue. If so I will make a new 16.2k mod that has soldered connections as opposed to quick connects. Hope that is all this problem is, I have to take my 13 year old daughter out Elk Hunting this next week...

My pondering was correct. The connections in the 16.2k mod had come loose causing the problem. Putting it back to stock fixed it. I will make up another resistor pack with everything soldered together after hunting season is over.
