Why does my MaxxForce diesel have low ICP?
The HPOP (high pressure oil pump) supplies the high pressure engine oil to the hydraulic operated injectors so if pressure drops the injection system will fail or run poorly. Our shop has had some experience with low ICP which can be mechanical due to a faulty o-ring on an injector or high pressure manifold.
