Code P0601?
This code is not on the list I've got. Any ideas? The cel came on and the truck started putting out black smoke on acceleration only. The truck runs fine, and pulls the 12k# 5er without a problem. It also started overheating when doing hard climbs recently. The cooling system was flushed about 13k miles ago.

Internal control module checksum error... Perhaps a bad (or going bad) PCM? Are you running a tuner? If so, roll back to stock ASAP. See if things get better. I need a tech to chime in on this. vloney, bowtiehatr or someone??

Disconnect both of your batteries, negative cables first and turn your lights on for 10 minutes (with the batteries disconnected) and see if that cures your problem. It's a KAM communication code I think. What are you reading codes with?

Went to a Ford dealer that has a service rep that knows how to do diagnostic checks, but no diesel tech. He indicated he thought that an injector was the cause and recommended a tech about 70 miles away. The tech they used to have quit and went somewhere else. The guy who checked it is honest but is no expert on 6.0's. What is a KAM communication code?

I got a PM from a tech who told me P0601 was not in the 03-06 pced. I think it's a trash code set from something else that might have happened. Is your truck still smoking and overheating, because that sounds more like a turbo problem or a fan problem or both. Maybe it's a harness problem causing multiple things and the PCM doesn't know what to show?
I used to get this code when I was having an extended crank to start, along with a cam and crank position sensor code and a couple of EGR codes, but my EGR is, for all practical purposes, deleted. Turns out it was the tune I had and since I got the latest flash and new tunes I haven't had a smell of a trouble code. I didn't get a CEL, just an extended cold start--probably 10 seconds of crank time.

Problem was Idle Control Pressure Sensor (ICP). Symptoms were intermittent fast idle (surging) at start up when cold, and sometimes it would surge at intersections while stopped. This seems to me a dangerous condition, because if you don't have your foot on the brake pedal at intersections, it could conceivably lurch into a person in the crosswalk. The initial trouble code was not correct. My truck has 111K miles, so if anyone else experiences this problem this maybe something to look at. The ICP was replaced and the cel and surging problem are gone. The tech recommended cleaning the EGR for the smoke on accel issue. The overheating is something I will address when towing again next year.

Question- "The tech recommended cleaning the EGR for the smoke on accel issue". I am wondering if you could verify this being the problem by disconnecting the EGR to test the problem or if it would still smoke even after disconnecting the EGR due to the existing buildup?

ICP is the injector control pressure sensor/switch.
If your EGR is already nasty to the point it's not sealing off good internally then unplugging it will not really help. It needs to be clean so it will seal before you unplug it. Even then, you might get a CEL depending on your flash, year model, or state location of your vehicle.

I have unplugged it in the past but because it is a CA truck it throws the cel on. npccpartsman, when you tacked it, did you throw a code. Simply tack welding it it seems too good to be true. I would like a simple way to eliminate the EGR but everything seems to be labor intensive and requires modifying the PCM to ignore changes to the algorithm of the computer with EGR not working. My experience with an after market chip was not a good and I want avoid chipping it to eliminate the EGR if I can.

Tack welding it was simply a way to keep it from ever opening. On a CA truck there's no way to keep the CEL off without a programmer. What programmer did you have? An SCT is really the only way to go on a 6.0 IF it's properly programmed.
