Retarded timing or timing that is too far out of range either way will cause white smoke. The fill stage pre-injection reduces the combustion noise, mechanical load and exhaust emissions. The maximum allowable leakage for one injector is 3 ml in 15 seconds, cranking or at idle. The return fuel from the fuel injectors flows through the injector return hose to a tee containing an orifice controlling the backpressure on the injectors, and from the tee back into the secondary fuel filter inlet fitting. A secondary, 2-stage radiator is mounted in front of the primary engine cooling system radiator.
The colors on our replacement sensor were indistinguishable from one another, therefore we simply matched the locations of the wires with that of the old connector. The best way to get to them is to remove the turbo. Of course the debris may have gotten into the injectors as well and could cause problems with a miss or rough run. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. There is really no commonality between the two engines besides the name. Look for injection control pressure sensors with direct-fit repair harnesses and precision cut threads for a perfect fit.
If it does, replace the injector. High Pressure Pump The high pressure fuel injection pump is gear driven by the camshaft gear and is located at the rear of the engine. Lack of power, rough running, diagnostic code P2291: This may occur on new trucks, trucks that have had the fuel filter or fuel pump replaced, the high pressure fuel system repaired, or have been run out of fuel due to air in the fuel system. Verify that the belt is not frayed and is tracking true, and there are no obvious pulley concerns. Verification requires disconnecting the turbo oil supply tubes replace the banjo sealing washers, W302474 and removing the turbo heat shield to inspect. Heater core noise: Some 2008 F-SuperDuty trucks built prior to 6-18-07 may exhibit noise from the heater core.
First, check the harness connector s at the affected bank s at the rocker box to see that they are fully seated. Any use of such information is at the user's sole risk, and in no event shall the provider be liable for any consequential, incidental, special, punitive or direct or indirect damages arising from such use. Fuel injector replacement, Field Service Action 07T07: Certain trucks built at the Kentucky Truck Plant between 4-3-07 and 5-21-07 have three injectors that may have had their polarity reversed. It is intended to be used with the proper tools to help diagnose and solve drivability issues. Do not use you fingers to find fuel leaks! There is a procedure for installing a temporary filter between the power steering pump and cooler to clean the system. Regeneration cycles will cause some fuel to leak past the piston rings in the cylinder and drain into the oil.
If the P2033 code resets right away, suspect a failed sensor. The injectors have a piezo stack instead of an electro-magnetic solenoid. If the observed acceleration deviates from the expected acceleration by more than 50%, then an additional routine is called that adjusts the injection energizing time until observed acceleration matches expected. A residue is normal, but puddles of oil are excessive. On all fuel injected engines there are only 2 types of design, port injection or throttle body injection. Film on inside of headlight: Some 2008 F-SuperDuty trucks may have headlights that appear foggy, smokey or seem to have a film on the inside of the lens.
Excessive blow by will be pushed out the crank vent and pulled in by the turbocharger. Crank the engine and watch for fuel flow from the valve. Ive been a Ford diesel tech for about 4 years now and 6. You must compare the amount of oil at the compressor inlet with the amount of oil at the compressor outlet, before condemning a turbo. This can lead to injectors leaking after the engine is off and flooding the engine with fuel.
Fuel Injectors The fuel injectors are connected to the high pressure fuel rail and deliver a calibrated amount of fuel directly into the combustion chamber. Or less likely that you have 4-6 glow plugs that have opens and are not working. If the pump is still not reaching its target goal, unplug the reductant dosing module injector , remove it, and see if it leaks when the pump is commanded on. Fuel Supply and Fuel Filter Housing The electric fuel pump in the fuel conditioning module draws fuel from the fuel tank through the fuel supply line. Clear the code and drive the vehicle to clear the warning message. Referrence bulletin Q-157 at for more information.
Verify the system is completely filled and bled as per the service manual. The 2 compressor wheels are similar to each other. Considerably more air is forced into the intake manifold causing the pressure to be much greater than normal atmospheric pressure. Engine sounds like it is cranking faster than usual. The turbocharger uses variable vanes that surround the turbine wheel to dynamically adjust turbo speed using exhaust gases.
