Power Stroke 7.3 Liter Diesel Engine Low Pressure Oil Flow The Power Stroke 7.3 Liter Diesel engine lubrication system is comprised of a low-pressure system and a high-pressure system. The low-pressure system provides primary engine lubrication while the high-pressure system provides the hydraulic pressure required to actuate the fuel injectors. The low-pressure lubricating system draws oil from the…
Power Stroke 7.3 Liter Diesel Engine High Pressure Oil Flow During initial start or cold start, the Power Stroke 7.3 Liter Diesel Engine 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…
Key On Engine Off (KOEO) Injector Electrical Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test determines if the injector circuits and solenoids are electrically operating without fault. All injectors will first buzz (audible feedback of the injector solenoids energizing the injector…
7.3 Powerstroke IPR General Info: A Power Stroke engine utilizes an electromagnetic spool valve, to regulate the HP oil pressure on the engine to tailor the injection characteristics of the injectors. This valve is called the Injection Pressure Regulator or IPR. In the 7.3 Power Stroke engine, pressure control in the injector control pressure system…
The injector control pressure (ICP) sensor is on both the 7.3L and 6.0L Powerstroke engines. They use a high pressure oil system as a way to pressurize fuel in the injector body. ICP sensors on the Ford 7.3 diesel engines read the oil pressure in the HPOS. This allows the PCM to increase or decrease…
