icp actual higher than icp desired - P2284 & P2288
2 Attachment(s)
Just got through installing new d-plugs, standpipes, and stc fitting update on my 2006 6.0. This was to repair a no start when hot and extended crank when cold. After I finally removed all the air out of the oil from the repair I noticed I have a new problem now. The icp actual pressure at idle is 1050psi the desired is 570psi when hot or cold. The pcm detected the problem threw the p2284 &p2288 codes and sent the engine into default mode 870psi. Soon as default mode hits the engine idles badly, turn the key off start it back up idles perfect for five seconds then pcm detects fault again then starts idling bad again. Replaced icp, ipr with same results. There is not a whole lot of icp high problems but need some help with this one. Dutycycle at idle is 15%, the desired icp and actual do match up off idle but not at idle, truck run perfect before default hits even at 75mph. I know its long but thanks for taking the time to read.
The parts I replaced did fix the no start when hot, just trying to look at the bright side!
