I cleared all codes, reran the tests, KOER and KOEO. This was all done after checking the resistance on all injectors. They all come out the same and with in specs.

These are the new codes that I get with the AE Scanner on my laptop.
P0475
P1280 ICP too low.

Now on the idle I am running a Injection pressure of 481.96 psi and at 2200 rpm it is at 1153.2 psi. Do these numbers sound right?

The truck is the same as before, so no change.

Just for giggles try running it with the ICP disconnected......or have you done this already?

And just so we are all on the same page here - the truck is missing at idle and under load, correct?

Would you guess it is a steady miss, or more of a random misfire?

There are no more CCT faults?

No actual CEL when running?

There are no more CCT faults? none

No actual CEL when running? no light

I will try the CCT with the ICP unplugged when I get back home.

But why is the P0475 code in there?
