P1093 Large Leak; difference between commanded fuel pressure and actual pressure is greater than 20 Mpa. Short drive cycles and other codes that may stop regeneration are the typical causes. Stripped allen head return banjo bolts may not torque or seal properly. In on minute at idle the high resolution circuit needs to read about 180,000 windows, in order to not set a code. Do not forget to share and love our reference to help further develop our website. Higher oil pressure and volume at higher rpm will force the unison ring to move, the turbo needs to be replaced. The design of these turbos is nearly identical to 6.
Fuel Supply and Fuel Filter Housing The fuel filter housing is on the suction side there is not a supply pump from the factory and are prone to suck air. Fuel is drawn through the diesel fuel conditioning module 8 , which combines a water separator, hand operated fuel prime pump, filter element and then through a fuel filter vacuum switch 9 to the fuel injection pump. So we attempted to get some good duramax lly map sensor location graphic to suit your needs. The fuel tank pick up may also be plugged. This procedure is best performed with the turbo as hot as possible as metal expands with heat, so allowing the turbo to cool may not give you an accurate gauge of its condition. Pressurize the return circuit with the valve covers off and look for bubbles or vacuum test the return circuit off of each head, the return should hold 15 inches Hg of vacuum. This will provide a look and see distant generalization of what you may be getting into and some live experiences of those who did.
Common items that suck air are old fuel lines, bad o-rings in quick connect fittings, tank switch valves, primary fuel filters especially early 6. Crack open fuel lines to see if knock goes away. Now on to the location. I searched it and something to do with vane position lly does not have an iat 2 sensor. Repeat above steps on the other bank of injectors.
This code usually sets when the unison ring in the turbo is sticking. Try increasing the rail pressure, we find injector nozzles that leak at idle pressure, but do not leak at higher pressure. If the return volume is less than 144 ml for all 8 injectors, refer to the high pressure pump test. Known area of harness rub-through. If it is more, replace the regulator. Use the following information regarding diagnostic trouble codes in addition to the normal diagnostic procedures outlined in the service manual or technical service bulletins. It is normal for the turbo to discharge oil from the compressor housing.
Perform diagnostics as outlined in service information. If there is any movement, the reluctor wheel retaining bolts are loose. However, using the scan tool to kill the injector does not reduce rail pressure in the injector and the tip can still leak fuel, cap off lines one at a time to pinpoint injector. Any Ideas why it's Boosting so High? You will need to try to fix the one you broke or just go buy a new one. Retarded timing or timing that is too far out of range either way will cause white smoke. I offered to burn a friends 2007.
Use the following information regarding diagnostic trouble codes in addition to the normal diagnostic procedures outlined in the service manual or technical service bulletins. More than 20% idle time is excessive. Duramax Lly Map Sensor Location -- thanks for visiting our site, this is images about duramax lly map sensor location posted by Maria Nieto in Duramax category on May 01, 2019. When they fail it is often catastrophic and they send metal particles throughout the high pressure side of the fuel system, causing further damage. Unless you know where to get the tool that sees through black rubber lines to find air, your only other option is to bounce around and replace parts.
Turn off ignition and record measurements. If an injector is leaking excessively into the return the balance rates are often at the edge of specification. If the return volume is greater than 72 ml per bank, replace any individual injector with return volume greater than 18 ml. Or run without it, it seems to run just fine The sensor that you broke that is on the lbz y bridge. I gave him the plate for free just because it ran so bad without it while tuned with the edge. If return quantity exceeds 450 cc in one minute at idle, then the injection pump is worn out.
Doing this correctly requires special tools. There is normally a pick up sock or fuel strainer in the tank. This switch will also be in trucks without rear steer! If it is oil smoke; how many miles per quart of oil burned? Truly, we also have been realized that duramax lly map sensor location is being one of the most popular subject right now. If my truck was throwing supercharger codes I would assume it has a supercharger. This direct replacement Cartridge allows you to repair your turbocharger without needing to purchase an entire turbocharger assembly. An essential component of the turbo system, replacement of a failed original turbo cartridge will restore drivability and proper engine performance.
Also look at the balance rates, if the tip is leaking fuel then the balance rates may be out of specification. Check the service manual for the year you are working on. Each Wicked Wheel 2 from Diesel Site has been tested in multiple wheel configurations of blade numbers, dimensional changes and pitch adjustments before coming up with the absolute best results for each application. Fuel Supply and Fuel Filter Housing The fuel filter housing is on the suction side there is not a supply pump from the factory and are prone to suck air. Signal x 0 x x x Cam signal x x 0 x 0 Crank signal 0 x x 0 x Will it start? Usually sets in conjunction with a P003A Turbo Boost Control Position Not Learned code. Remove return hoses from one bank of injectors. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.
Excess idle time could be defined as leaving the pick up running while hooking up a trailer. More than 20% idle time is excessive. If you still have too much restriction after changing the filter, check for collapsing soft fuel lines by the drivers side valve cover and under the truck near the transmission. If the coolant level is low, diagnose the cooling system. A bad Fuel control Solenoid part of the injection pump can cause the same symptoms and codes. The design of these turbos is nearly identical to 6.
