J1939 Code and Description CDL Code and Description Conditions which Generate this Code
157–17
Engine Injector Metering Rail #1 Pressure : Low - Least Severe (1) E398(1)
Engine Injector Metering Rail #1 Pressure : Least Severe (1) The fuel rail pressure is lower than expected.
157–18
Engine Injector Metering Rail #1 Pressure : Low - Moderate Severity E398(2)
Engine Injector Metering Rail #1 Pressure : Moderate Severity (2) The fuel rail pressure is lower than expected.
1440–0
Engine Fuel flow Rate #1 : High - Most Severe (3) E1106(3)
High Fuel Rail Pump Flow : Most Severe (3) There is excessive leakage in the high-pressure fuel system. The code is logged. The check engine light will illuminate.
1440–15
Engine Fuel Flow Rate #1 : High - Least Severe (15) E1106(1)
High Fuel Rail Pump Flow : Least Severe (1) The ECM has detected that the fuel leakage on the high-pressure fuel system is above an acceptable threshold.
1440–16
Engine Fuel Flow Rate #1 : High - Moderate Severity (2) E1106(2)
High Fuel Rail Pump Flow : Moderate Severity (2) This code will only trip if an issue is detected in the low rail pressure range of operation. The check engine light will turn on when the code is tripped. This action signifies an increased risk that the engine might not restart if the engine is shut off. The truck should be taken to safe place for service.
5585–17
Engine Injector Metering Rail #1 Cranking Pressure : Low - Least Severe (1) E1220 (1)
Low Cranking Fuel Rail Pressure The fuel rail pressure is too low while cranking. This action can be caused by a fuel system service prior to starting the engine.

Troubleshooting Test Step Value Result
1. Check for Codes
A. Turn the keyswitch to "ON".
B. Connect Cat® Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
C. Determine if the diagnostic trouble code that directed to this procedure is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this procedure.
Codes
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Refer to the appropriate troubleshooting story.
Result: A 157, 1440, or 5585 code is present.
Proceed to Test Step 2.
2. Check the Low-Pressure Fuel System
A. Start the engine.
B. Connect Cat ET to the service tool connector.
C. With the engine running at low idle, record the "Fuel Pressure" value.
D. With the engine running at high idle, record the "Fuel Pressure" value.
Fuel pressure
Result: The gauge value is greater than 250 kPa (36 psi) at low idle and greater than 450 kPa (65 psi) at high idle or the engine does not start.
Proceed to Test Step 3.
Result: The gauge value is less than 250 kPa (36 psi) at low idle and/or less than 450 kPa (65 psi) at high idle.
A problem has been detected with the low-pressure fuel system.
Repair: Refer to Troubleshooting, "Fuel Pressure Is Low (Fuel Transfer System)" to troubleshoot the cause of the low pressure.
3. Check the Fuel Rail Pressure Sensor
A. Turn the keyswitch to "OFF".
B. Allow the engine to sit for 10 minutes.
C. Turn the keyswitch to "ON".
D. Connect Cat ET to the service tool connector.
E. Monitor the "Fuel Rail Pressure".
Rail Pressure
Result: The fuel rail pressure is less than 5000 kPa (725 psi) after 10 minutes.
Proceed to Test Step 5.
Result: The fuel rail pressure is greater than 5000 kPa (725 psi) after 10 minutes.
Proceed to Test Step 4.
4. Check the Fuel Rail Pressure Sensor
A. Turn the keyswitch to "ON".
B. Vent the pressure from the fuel system. Refer to Testing and Adjusting, "Fuel Rail Pressure – Release".
C. Turn the keyswitch to "ON".
D. Connect Cat ET to the service tool connector.
E. Monitor the "Fuel Rail Pressure".
Rail Pressure
Result: The fuel rail pressure is less than 5000 kPa (725 psi) after mechanically venting the pressure from the fuel system.
Proceed to Test Step 5.
Result: The fuel rail pressure is greater than 5000 kPa (725 psi) after mechanically venting the pressure from the fuel system.
The fuel system has been mechanically vented. A failed fuel rail pressure sensor has been detected.
Repair: Replace the fuel rail pressure sensor.
Proceed to Test Step 9.
5. Check the Torque On All The High-Pressure Fuel Lines
A. Check the torque on all the high-pressure fuel lines on the fuel rail, from the fuel rail to the cylinder head.
B. Check the torque on all the high-pressure fuel lines on the fuel pump and high-pressure junction block and connection points in between.
Torque value
Result: All torque values are within specifications.
Proceed to Test Step 6.
Result: All torque values are not within specifications.
Repair: Tighten the lines and/or accumulators quills that were not properly torqued.
Proceed to Test Step 9.
