What should injection control pressure be on MaxxForce?
Bookmark this This running test for injection control pressure (ICP) is a good test to run since these specs determine the fuel injection operation. This is the DT MaxxForce which requires 870 psi of ICP to run while the maximum can go as high as 4500 psi.
What kind of ICP do I need for MaxxForce?
This is the DT MaxxForce which requires 870 psi of ICP to run while the maximum can go as high as 4500 psi. These high pressures create problems if there is a leak in the high pressure manifold or anything else related in the system.
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.
What happens when ICP sensor code is incorrect?
An ICP pressure sensor code will fool the engine computer with an incorrect reading which will derate the engine. Working with high pressures causes problems and seeks out all of the weak spots.
Where is the fuel pressure sensor on a MaxxForce 7?
During engine operation, if pressure is low, the ECM turns on the amber FUEL lamp to alert the operator when the fuel filter needs servicing. Sensor Location The EFP sensor is installed in the secondary fuel filter housing on the top front of the engine.
What should the air pressure be on a MaxxForce diesel?
Shop air usually runs around 120 psi so when that is hooked to the manifold inlet the leak will be obvious most times. An ICP pressure sensor code will fool the engine computer with an incorrect reading which will derate the engine. Working with high pressures causes problems and seeks out all of the weak spots.
What is the code for MaxxForce DT fuel delivery?
The code was DTC N/A SPN 94 FMI 1 Fuel Delivery Below Critical. We just had one of these. Try to clamp off the return from the fuel filter canister (Grey/silver line).
What causes low ICP on MaxxForce diesel pump?
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. One step for troubleshooting is applying shop air to the high pressure manifold which eliminates the high pressure oil pump all together.
Why does my MaxxForce 13 have high pressure?
Bad high pressure pump is probably the most common cause. (12-30-2018, 10:43 AM)IROC Wrote: Bias pressure sensor? Leaking injector? (but that wouldn’t cause high pressure) There could be any number of things causing the issue. Bad high pressure pump is probably the most common cause.
