Royok,on the ma side.there is a desired and actual reading for the quantity control valve current draw.what is the low pressure fuel pressure readido you have the service link program from freightliner???ok,valve is working.can you get to the screen for low pressure fuel pump and tell me how many bar it is putting out??? also,have you pulled theok,look for the fuel pressure for me20 bar is not enough on the high side.if the low side is around 7-10 bar then the fuel pump has failed.if that is the case,make sure there is nothat is correctok,good,then low pressure pump is good.it needs a high pressure fuel pump.get the pump,lines.Roynot sure,I believe it is low preesure pump output yes,7-10 bar 1 bar equals 15 lbs quantity control valve comes with the new pump.the spec of 1DD15 Troubleshooting - Section 16.10 Pressure Limiting Pressure Limiting Valve Trend Data Examples Component Normal PLV (cold start) Normal PLV (after drive cycle) Normal PLV (after drive cycle) Leaking PLV Fuel Rail Surface Temperature 82-89°F 187°F 168°F 90-97°F PLV Line Surface Temperature 76-77°F 160°F 155°F 105-108°FVersion Conducted ForCoolant Pressure at Jacket Inlet,kPa (gauge) 250 250 Exhaust Pressure in Tailpipe,kPa (absolute) 105.5 125.5 Air Pressure in Intake Manifold,kPa (absolute) 202.5 327.5 Air Pressure in Engine Intake,kPa (absolute) 96.4 94.8 Ranged QuantitiesC,units Coolant Flow Rate,L/min 340 to 360 340 to 360
