Electronic service tool will change to INACTIVE immediately after the diagnostic runs and passes. I know the fuel pressure sensor has been changed. This truck has had a lot of mechanics work on it so Im not sure what alls been done so far. If fuel inlet restriction is not excessive, the source of air entry could be isolated to one of the following: suction fuel lines, OEM fuel lines, suctionside fuel filter assemblies, or stand-pipe(s) in the fuel tank(s). Engine fuel 1 injector metering rail 1 pressure ulcer. CAT Engine Reprogramming Tool for flash programming C1. Cummins ISX15 CM2250 (2010-12) Fault Code: 559 (CL) PID: 157 SPN: 157 FMI: 18 Injector Metering Rail 1 Pressure- Data Valid But Below Normal Operating Range- Moderately Severe Level.
Online for applicable fixes to the calibration stored in the ECM. If the accuracy of the fuel rail pressure sensor is being questioned, a key ON accuracy check can be performed. Engine could possibly not start. 0% found this document useful (2 votes). 2022 ( 1 PC)ISUZU $126. Air-in-fuel will cause starting complications. Use the following procedure in the ISC8.
Check the High Pressure Connector (HPC) and connector torque and torque to specification if necessary. When Fault Code 559 occurs, the fuel system has lost the ability to maintain rail fuel pressure. Document Information. Original Title: Full description. PDF, TXT or read online from Scribd. 3 and ISL9 CM2250 Service Manual, Bulletin 4022257. Restricted fuel screen, located in the banjo bolt, at the high-pressure fuel pump inlet, if equipped. SPN 101 - FMI 16 (Fault Code 555). A foamy appearance is an indication of a leak that allows air to enter, a severe inlet restriction that causes cavitation, or a system that is not yet primed. Engine fuel 1 injector metering rail 1 pressure washing. Fault Code 559 sets when the engine is operating and measured rail fuel pressure remains at least 250 bar [3625 psi] less than commanded pressure. Everything you want to read. 559 is likely going to be a bad front fueling actuator.
The pressure control loop relies on fuel pressure supplied to the high pressure pump by the fuel gear pump. Report this Document. Anyone have any experience with these codes? Engine fuel 1 injector metering rail 1 pressure freightliner. If the engine will not start, Fault Code 559 becomes active during cranking, and no speed sensor fault codes exist, it is likely that the engine is not developing rail pressure during cranking. Allison 1000 & 2000 Gen 4 Fault Codes: U1301 J1850 (Class 2) Serial Data Communication Link Low1000 & 2000 Gen 4 $50. Since you are not, it is very very unlikely that there is a blockage in only the front bank of cylinders and not the rear. Bobcat Service Library [03.
Another mechanic changed out the fuel filters and screen. Intermittent ECM power supply connections can cause Fault Code 559. The fault code status displayed by INSITE? The ECM has detected the measured fuel rail pressure is below the commanded fuel rail pressure by at least 250 bar [3625 psi] for 7 seconds. The troubleshooting has been designed to isolate the problem into four categories: 1. SERVICE MANUAL International Engines MaxxForce 11 & 13 (2014 & Newer)INTERNATIONAL ENGINES $20. The steps of this fault code tree assume that the fault condition is repeatable (this does not necessarily mean that the fault code is active with the engine at idle). I cleared the codes and after driving it under a load the 559 code comes back but the crankcase pressure codes dont. SERVICE MANUAL HINO 2018HINO $41. The ECM illuminates the amber CHECK ENGINE lamp and/or the malfunction indicator lamp (MIL) immediately when the diagnostic runs and fails. • Fuel gear pump pressure. Allison DOC 2019 PC software + GEN5 2019 truckAllison $40.
Circuit Description. There are two fuel pumps - priming pump (used before start) and gear driving pump. Damaged ceramic plungers can cause severe engine damage. Changes to the flow command result in the opening (or closing) of the fuel pump actuator to supply more (or less) fuel to the high pressure pump. At key ON, a depressurized rail pressure sensor should read 0? Allison 1000 & 2000 Gen 4 Fault Codes: P1892 Throttle Position Sensor Pulse Width Modulation (PWM) Signal High Input1000 & 2000 Gen 4 $50. Causes of this fault include: • Fuel inlet restrictions. Operate the engine on a chassis dynamometer or conduct a diagnostic road test to duplicate the fault code. Eaton Service Ranger 4. Fuel rail pressure relief valve opens at a pressure too low (Fault Code 3727 detects this condition). Conditions for Running the Diagnostics. Is this content inappropriate?
It is typical for Fault Code 559 to become active when the engine is heavily loaded and become inactive when the engine is lightly loaded. For engines with high counts of inactive Fault Code 559, or if the troubleshooting tree has been exhausted, operate the engine on a chassis dynamometer or conduct a diagnostic road test to duplicate the fault code. If the engine is running with an active Fault Code 559 and Fault Codes 449, 1911, or 2311 are not present, check the ECM power supply for intermittent connections or battery issues. Which would expose the fuel system or internal engine component to potential contaminants prior to disassembly, clean the fittings, mounting hardware, and the area around the component to be removed. 5) High-pressure fuel pump head failure. Engine torque will be reduced if the engine is operated for an extended period of time with this fault active. Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system, to allow the pressure to decrease to a lower level. Isuzu E-IDSS Diagnostic Service System 04. This diagnostic runs continuously when the engine is operating. Electronic service tool can be used to clear active and inactive faults, as well as extinguish the MIL for OBD applications. Sticking check valve in ECM cooling plate. It could be necessary to manually relieve the pressure from the high pressure fuel rail. EFFECT: Possibly hard to start or low power. The fuel pump, high-pressure fuel lines, and fuel rail contain very high-pressure fuel.
The procedures referred to in this troubleshooting tree also have checks for engine no start conditions.
