Problems with 6.0 P2290
So i gave up and thought i would take the Ex to the dealership to have my problem diagnosed. Keep getting a CEL P2290... Any way fixed the STC fitting on the HPOP and then began getting the code... The dealership called today and said that they needed to start looking for an electrical problem... Anyone ever heard of an electrical problem leading to this code with the 6.0? I changed the IPR and ICP because i knew they could be culprits... could not find a leak with an air pressure test. I don't want to get into a situation that we start hoping for a fix or not knowing what to look for... I do most of the work on my vehicles myself and have had bad experiences with dealerships in the past... The code only came on when hauling a 32 foot travel trailer or at high acceleration or going up a bridge...

This would be a good question to take to the 6.0 engine forum. You've already done the obvious in changing the ICP sensor and the IPR. I know a bad connector has been known to cause that fault, but you will get more expert help over in that forum. Make sure to note what year you have.
