Need Help!! ICP/Turbo issues!

[Maxton46]

CEL popped up and reads ICP sensor code, replaced the sensor to no avail, now turbo drops off randomly while driving. checked wires on sensor and they seem good. If i cannot find a cause/solution for this the company is going to sell our baby! please help.

2005 F-450 Superduty. 6.0L Turbo.

need to know what code , there are 20 different ones for icp, give me the code and ill tell you what is wrong

Lost the original code readout and cannot get it scanned today, we are almost positive the code was the p2286, ICP signal is higher than specified value. We just need to know what we have to replace/repair because it's been to Ford (Swapped the sensor, wiped the code, said it was good... it wasn't) and a second mechanic, (checked the wires, made a repair to them, could not get authorization from enterprise to replace the harness.) and now the problem has been kinda kicked to the back burner. If i can bring a definitive answer to the powers that be i might be able to save the truck.

A complete list of symptoms includes,
Occasional rough idle.
Stalled out while warming up once.
Turbo gauge stops functioning intermittently, almost positive the turbo has cut out when this happens.
More power on the highway and during acceleration.

p2286 is definitly a wiring issue , if sensor is new the whole connector really needs to be replaced , if that doesnt fix it then need to folow wiring back to pcm to see if there are any rubbing anywhere , 05 was not bad for that just sensor and connector , you still may have a turbo issue , maybe even egr valve causing low power concern , doesnt make since to get rid of a truck just for a small problem

Anyone know where i can find the wiring harness for sale? No luck searching the web. Is this strictly a ford direct part?


Oh yeah, new issue... While driving down the highway, this is the second time it has happened, begin to hear a sound like someone just turned on a vacuum cleaner under the hood. I'm leaning towards the turbo..... Had a truck just die on us last week, making that sound, but it was constant, this one like i said happened twice and only for a few seconds.

turbo isnt the problem, more than likely egr is opening when it shouldnt , dont need whole harness , just the connector which you can buy from ford

Thanks for all the information, really appreciate it, I'd hate to see a good truck die young. One more question, EGR was replaced about 20,000 back, would this lead you to beleive there may be another underlying issue with it? Or is this a frequently replaced part? These trucks take a beating doing what we do, clocking almost 70,000 in a year and a half. Could this be the cause of the EGR problem?

yes!!! if you let the truck idle for long periods it will make it more frecuent also check the ficm it may be on its way out.....any smoke or anything else?

No smoke, just the symptoms above.
