This category is dedicated to the legendary Ford PowerStroke engines including the 7.3, 6.0, 6.4, and 6.7 liter diesels. We also cover some topics on the smaller 3.0 PowerStroke. From our guide on rebuilding the 7.3 PS IPR to bulletproofing the Ford 6.0 PowerStroke we have dozens and dozens of helpful, quality Ford PowerStroke articles.
The Ford 7.3L Powerstroke diesel is a legendary engine. It’s well known for its reliable history and solid performance from the factory considering the era it was released. However, there are many ways to get more performance out of the 7.3 turbodiesel Powerstroke engine. Of course, risks exist when upping the boost and power with…
A hard start or no start issue can be a troublesome problem to run into on the 7.3 Powerstroke. There are a number of sensors and other engine components that can cause both of these issues which makes it difficult to pinpoint what the exact problem might be. This guide is going to discuss the…
Power Stroke OBD-II Code P1211 – “ICP Higher/Lower Than Desired” (7.3L) OBD-II Code P1211 from a 7.3 Liter Power Stroke is often caused by running “Hot Chips” or tunes that are demanding more ICP (Injection Control Pressure) than the HPOP (High Pressure Oil Pump) can deliver and can be accompanied by a lack of power or…
The 7.3 Power Stroke diesel engine is: a four-cycle turbocharged V-8 with overhead valves. 7.3 liter (444 cubic inch) displacement. Separated into two banks, the right bank numbered 1, 3, 5, 7 and the left bank numbered 2, 4, 6, 8. rated at 250 horsepower for automatic transmission and 275 horsepower for manual transmission. Â The…
Purpose:To determine if the PowertrainControl Module (PCM) has detected any fault conditions that would cause a hard start or no start condition. Key On Engine Off (KOEO) On-Demand Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test will check that all inputs…
Purpose:To determine if the injection control system can supply enough injection control pressure to sustain starting. Recommended Procedure:Connect OBDII Scan Tool to the data link connector (DLC) under the dash. Access ICP PID on Scan tool menu nd monitor ICP reading while cranking the engine. Note: CMP signal is required before injection control pressure is allowed…
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…
Ford’s turbodiesel 6.7L Power Stroke V8 is already an impressive engine from the factory. Early models come in at 400 horsepower and 800 torque following the software update. 6.7 Power Stroke performance only improved throughout the years. 2020 Power Stroke’s now make an insane 1050 torque. However, all these numbers may not be enough for…
