HELP!! CEL driving me CRAZY!!

[boomboy110]

I have a 07 F250 crew cab. I have installed a CAI, Edge programmer, and cat-deleted perf. exhaust. system. I had white smoke coming out and losing coolant. Had no CEL and truck seemed to run fine otherwise. Took the truck to dealer, and they replaced EGR cooler, and rebuilt the Oil cooler. THey also replaced the ICP sensor, and connecter going to it. Now I get a CEL with code 2284. THe dealer could not figure out what is causing the code, said with their computer hooked up the sensor reads fine before and after CEL appears. They tried blamin it on my programmer, but I had removed it before dropping off and had no CEL or other problems, I had all Performance parts on before having the smoke problem. Now, not only do I have the CEL, but the truck runs VERY rough on cold startup, than has a delay when you rev up engine after it is warm. Also, while Cruise Ctrl is set, it at times sounds like the injectors are misfiring or something. Also seem to be blowing black smoke out of exhaust on cold starts, and heavy accelerations. Where this wasn't happening before going to dealers. Any ideas are greatly appreciated. I've tried hooking up programmer and running it in different programs. Sometimes the CEL stays out for 80 miles, than reset it and it might come on after 8 miles. Please help, as that little light being on bothers me enough, but the truck running unlike it should be just bugs the PISS out of me.

P2284-Injector Control Pressure Sensor Circuit Range/Performance= See diagnostic manual ICP System. In other words, the dummies screwed up the wiring when they put the connector back together. That would be the logical answer.

Thanx deucer. That was my thinking also. Since I didn't have the problem before, than they replaced the sensor and connector and now there is a problem. But, they said it is reading fine while they have it hooked up to their computer. So that had me dumbfounded.

They could have it hooked up and read the voltage and amp input/output, but if they have crossed the wires the sequence could be backwards. I don't know what they are checking the system with and if they are checking in way that will alert to this anomaly. Either the wires are crossed or you ICP is toast again, or maybe it's in the FICM. I doubt that because everything was fine until they changed the ICP right?

[deucer]

Your truck is a 6.0L isn't it? If so, I believe your ICP should be on the right valve cover. If I am correct, you can check the connector to see if the wires were crossed as I have the diagram as to how they position. Again assuming everything is the same, it should be a female connector with 3 holes. You have the latch or keeper (locks connector to receptacle), in your hand and just below it you have 2 slots and below them 1 slot. With the plug staring you in the face the wiring goes Top left is #2 slot and it is Brown/white wire, Top right #1 slot is Gray/Red wire and the Bottom #3 slot and is Dark Brown/Light Green. You might look and see.

Yeah I have the 6.0. I checked the plug going to the sensor, which yes they did replace it, all the wires were in the correct slots. Unfortunately, was hoping it was gonna be something dumb and easy. So, anyother ideas would be great. Would my programmer have any reason for this happening?

make sure they replaced the ipr screen when they did the coolers. or the ipr valve is going out

[jthomas]

the pig tail connector for the wires are all black

If this vehicle is flagging a HARD P2284 fault like you describe, there HAS to be an issue related to the workmanship in the joining/soldering of any one or all three of the wires to the ICP sensor, no ifs, ands or buts about it. My suggestion is for you to monitor ICP psi, ICP volts and ICP desired with the engine running, "wiggle test" the wiring to see if the engine reacts in the same manner you describe. FYI, ICP psi and ICP desired should always almost mirror each other under all operating conditions. If you see ICP volts "jump" to 5.00 volts or close to it under any condition, THAT is what is causing P2284 to set.

m-chan68-Thanx, that's pretty much what I had figured too, seeing how I had no problem before, than they replace the sensor and pigtail and now there is a problem. But I can't see where they splice the wires because like you said, jthomas, they have black heat shrink over where they spliced the wires together. I had to peel the electric tape off to get back to the original wires in order to check to see if they had put the wires in the correct slot. It will be going back to the dealer soon to have it checked out. now I am not very familiar with how to check to make sure it's getting the proper reading and I am not sure if my OBDII reader will give me the readings, I do however, have a digital multimeter, is there a thread or a short description on how to check to see what kind of readings the sensor is getting and check the ICP volts? I'm new to the diesel world but am very familiar with working on cars, and I am usually pretty good with electrical problems, so just an idea of how to know what the desired should be in relation to the actual would be great. thanx for all your help.
