Photo 4/14 | 1009 Ford Power Stroke Controls high Pressure Oil Pump | The 7.3L and 6.0L HEUI systems use an engine-driven high-pressure oil pump to create injection pressure for the fuel injectors.
Photo 5/14 | 1009 Ford Power Stroke Controls thepiezo Injector | The piezo injector from a 6.4L does not interface with engine oil, it is attached to a common-rail fuel supply.
Photo 6/14 | 1009 Ford Power Stroke Controls idm | The 7.3L engine design employed an IDM to open and close the HEUI system's injectors.
Photo 7/14 | 1009 Ford Power Stroke Controls ficm Injector Operation | Injector operation on the 6.0L was the function of an FICM, which replaced the 7.3L's IDM.
Photo 8/14 | 1009 Ford Power Stroke Controls maf Sensor Hot Wire Design | The 6.0L and 6.4L Power Stroke engines' MAF sensor uses a hot-wire design. The PCM or ECM measures the current required to keep the sensing wire at a predetermined temperature.
Photo 9/14 | 1009 Ford Power Stroke Controls maf Sensor And Iat Unit | The MAF sensor incorporates IAT #1 sensor internally. The MAF and IAT #1 can be considered one single unit.
Photo 10/14 | 1009 Ford Power Stroke Controls pcm Mounted Under Hood | Trucks equipped with the 6.0L have the PCM mounted under the hood on the driver-side fender. The unit has three plugs.
Photo 11/14 | 1009 Ford Power Stroke Controls camshaft Position Sensor | All the Power Strokes use a camshaft position sensor that is triggered by an interrupter on the timing gear.
Photo 12/14 | 1009 Ford Power Stroke Controls iat 2 Sensor | The IAT #2 sensor can be serviced separately. It measures the air temperature going through the intake manifold and can give some insight on the intercooler and turbocharger efficiency.
Photo 13/14 | 1009 Ford Power Stroke Controls bp Sensor | Exhaust backpressure is determined by the BP sensor.
