Hey guys..this morning the 99 Powerstroke 7.3 E350 CEL comes on after a cold start..it went off after I cycled the key and then it seemed to start fine with no illuminated CEL until late this afternoon when it did it again.
RAn the NGS with Red diagnostic card and came up with this...
P1280...ICP low input
Ran KOEO On Demand....sys passed
KOEO Injestor Test.....sys passed (injectors all buzzed the same and no mute)
It doesnt sem to run rough at all, but have no clue what this is truly indicating which is an obvious fault of sorts.
Injector harness was replaced brand new about 3 years ago and cant see this as the problem....
Went outside on ran some KOER tests...
KOER On demand...P0476 Exh Press ctrl valve code
Cylinder contribution tests ...sys passed (this test should be the final check of the harness am I correct?)
KOER Glow Plug Monitor..sys passed
Any help would be appreciated,
