I was getting on the highway and above half throttle the engine stumbled, quit accelerating. I pulled the code and got a p2290. ICP injector control pressure too low. Is this an icp problem, a wiring problem, or an ipr valve problem?
Pulled plug on ICP sensor and no help. I found an oil leak today also. it is dripping off the right rear of the engine. could this be a ipr valve leak? would this cause me to have no power above half throttle? it will run 70 all day long. runs strong up to 2200 rpm.
Would it not store a code if it was seeing a HPOP leak ? or ICP failure ???
and IF so would it store them or just show while it was doing it, maybe he can put a code scanner on and drive with it to see what comes up

ICP - usually
HPO leaks - not always
He did get the ICP code, which can be either a cause or an effect
If I am not mistaken, the way to test is to replace with known good one..
Would a bad icp make the truck not want to run right after half throttle??? Truck starts great, runs great to a point. will run 70 and has acceleration unless you get it to downshift and it gets up in the rpm range, then you get rpms and no acceleration!
