The fuel delivery pressure switch opens when the fuel system pressure reaches 365 kPa 53 psi or above. Go to the fuel system and look at the diagrams and footnotes. Finally, instead of a high pressure oil passage machined in the heads, the 6. Diesel Particulate Filter The diesel particulate filter traps soot from the exhaust to lower particulate emissions. Trouble Code Fault Location Probable Cause P0001 Fuel volume regulator control -circuit open Wiring, regulator control solenoid We recommend What Does Code P0001 Mean? It regulates the volume of fuel from the internal transfer pump to the high pressure pumping components. The filtered fuel leaves the secondary fuel filter and flows to the high pressure pump.
If the voltage ever drops below 0. The 2 compressor wheels are similar to each other. Perform the injector return flow test. But replacing parts based upon a code is not recommended. Ford Diesel Diagnostics 2011 — 2016 6. The longer the engine runs before it dies, the further back toward the tank the problem is.
This will require that the head be pulled in order to replace the glow plug sleeve. During certain driving conditions the engine will perform a regeneration cycle, which will use additional fuel injections and the catalyst to heat up the exhaust temperatures to the point where the soot will be burnt out and form ash. Connect the test light clamp to the battery negative post. These techs really have their hands tied most of the time. The rocker arms are prone to breaking or having the tips wear out.
The PowerStroke requires a special anti-foaming agent in its oil to prevent this aeration. Sounds like it may be a problem with one of the valves on the high pressure fuel pump. Try increasing the rail pressure, we find injector nozzles that leak at idle pressure, but do not leak at higher pressure. A small amount of return is normal, but more than 3 ml in 15 seconds while cranking or at idle is considered excessive. High pressure fuel entering your bloodstream may result in amputation or loss of life. If there is nothing in the intake side, remove the downpipe and check for excessive oil.
Verify that the injection pump has a good, clean, not aerated fuel supply. Fuel Coolers serve as a radiator for the fuel system. The pressure drop is enough for the upward force in the high pressure chamber to overcome the downward force of the control piston which allows the nozzle needle to move up, the fuel to atomize and enter the combustion chamber. These include lack of power and a no start condition. Examine the connections, do pin tension tests also smell for burnt wires. If it shows no oil pressure then there could be a problem with the low oil pressure side.
The nozzle needle is held closed by a spring and by fuel pressure in the control chamber. Serious bodily injury could result. Make sure the oil level is correct and the oil is in good condition less than 3000 miles before trying to cure any other drivability or starting issues. The tappet galleries pan before being routed through a passage in the block, a also provide oil to the piston cooling jets. Pull lightly on the feeler guage. This can be setup as a regulated return, or used on a pressure side of the pump with a return back to the tank. .
Volume control valve controls the low pressure side, the pressure control valve controls the high pressure side. A secondary, 2-stage radiator is mounted in front of the primary engine cooling system radiator. What is the Fitch Fuel Catalyst? This port is also used as the deaeration port. Normal oil change intervals are critical for this reason. It is also a good idea to check supply pressure with a gauge. Look through the pages in the 6. This pump is rebuilt in-house at Alliant, using 100% new volume control and pressure control valves, and bench tested to ensure desired performance.
Each fuel rail is connected to 4 injectors through individual high pressure pipes. The frequency is getting closer and closer. With this particular code, the solution could be simple or require extensive time to diagnose and repair. If the voltage does exceed this range, backprobe a ground into the ground circuit of the sensor, if the voltage is still above 4. There is really no commonality between the two engines besides the name. These changes make for a very different diagnostic process from the 7. If it does not, there is problem in the power supply circuit and you will need to consult the factory wiring diagram.
Gasoline and diesel is at its most optimal quality when it is first refined but unfortunately during storage and transportation, the fuel quality drastically diminishes. When energized, the piezo crystals expand, lifting the control valve off of its seat via a hydraulic coupler connecting plunger below to begin injection. Code P20E8 suggests the pump did not reach that target. If there is a measurable amount of return, the valve is bad. If the P2033 code resets right away, suspect a failed sensor.
