Hey guys, dad's SD 7.3 PStroke is leaking oil from his high pressure oil sensor. I am curious if that can be bypassed? Can we jumper the wires, or add a resistance to eliminate the sensor?

 

No, it cannot. I know what it does, I just cant explain it. :/ Hopefully someone else can, or you can try the 7.3 forum further down the list.

 

The vehicle can not run without the icp.
From the manual
Overview
The High Pressure Oil Control system consists of the high-pressure oil reservoir, highpressure oil pump, injection control pressure regulator, Injection Control Pressure (ICP)sensor, high-pressure hoses, and oil rails in the cylinder heads.
The High Pressure Oil Control system is used to actuate the HEUI fuel injectors. The PCM controls an electronic pressure regulator to regulate oil pressure to the injectors. The high-pressure oil flow within the fuel injectors is controlled by a solenoid located on top of the injectors. Oil pressure supplies the force needed to pressurize the fuel in the
injector to initiate fuel injection. High Pressure Oil Control Subsystem
Description & Operation The lubrication system is comprised of a low-pressure system and a high-pressure system.
The low-pressure system provides primary engine lubrication while the highpressure system provides the hydraulic pressure required to actuate the fuel injectors.
The low-pressure lubricating system draws oil from the engine oil pan through the oil pump screen cover and tube into the oil inlet passage in the front cover. The Gerotor oil pump pumps the oil back out through the outlet passage in the front cover. One oil path sends oil flow to the high-pressure pump reservoir initial fill gallery (integral to the cylinder block) and through the anti-drainback check ball. During cold start the oil feeds in two directions from the anti-drainback check ball. One feed leaves the check ball and enters the front cover. From there it enters the high-pressure oil reservoir. The second feed exits the check ball and enters the left bank valve lifter oil gallery. Pressurized oil that enters the turbocharger assembly lubricates the compressor/turbine shaft. The oil drains back through the turbocharger mounting pedestal and back into the oil pan. The valve lifter oil gallery supplies pressurized oil to the valve tappets and to the piston cooling oil jets. Oil from the valve tappets is routed upward to the cylinder head
valve train through hollow push rods. Oil drains back to the oil pan through return ports. High Pressure Oil System Explanation
During initial start or cold start, the high-pressure oil pump receives unfiltered oil from the left side valve lifter oil gallery through the anti-drain back check ball valve. Once the engine starts or during warm engine starts, the check ball closes and the high-pressure oil pump receives filtered oil from the high-pressure oil pump reservoir.
The high-pressure oil pump pumps the oil under extremely high pressures (4,115-20,577 kPa [600-3,000 psi]) through the left and right side high-pressure supply hoses to the high-pressure oil rails (integral to the cylinder heads). Once in the oil rail, oil is fed to the fuel injector bores through oil feed galleries (4) drilled and machined in the cylinder
head. The high-pressure oil then actuates the fuel injectors.

 

Thanks, new one it is!

 

do you have a diagram of how to rebuild the high pressure oil injection pump need to know which way thje springs go inside etc thanks , Shane
