SHAFT-PINION 2276056 - Caterpillar

Use this procedure to troubleshoot a high fuel flow in the high-pressure fuel system. Also, use this procedure if the following event code is active.
Table 1
J1939 Code and Description CDL Code and Description Comments
157-17
Engine Injector Metering Rail #1 Pressure : Low - least severe (1) E398 (1)
Low Fuel Rail Pressure The fuel rail pressure is below an acceptable level.
The code is logged. The check engine light will illuminate.
157-18
Engine Injector Metering Rail #1 Pressure : Low - moderate severity (2) E398 (2)
Low Fuel Rail Pressure The fuel rail pressure is below an acceptable level. The code is logged. The check engine light will illuminate.
1440-0
Engine Fuel Flow Rate #1 : High - most severe (3) E1106 (3)
High Fuel Rail Pump Flow 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 (1) E1106 (1)
High Fuel Rail Pump Flow There is excessive leakage in the high-pressure fuel system. The code is logged. The check engine light will illuminate.
1440-16
Engine Fuel Flow Rate #1 : High - moderate severity (2) E1106 (2)
High Fuel Rail Pump Flow There is excessive leakage in the high-pressure fuel system. The code is logged. The check engine light will illuminate.
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. Apply electrical power to the engine.
B. Connect Cat® Electronic Technician (ET) to the service tool connector.
C. Apply electrical power to the engine.
D. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Refer to the appropriate troubleshooting story.
Result: An E1220 or a 5585–17 code is present.
Proceed to Test Step 2.
Result: An E398, E1106, 157, or a 1440 code is present.
Proceed to Test Step 3.
2. Check the Service History.
A. An E1220 or 5585-17 code can be caused by a recent service on the fuel system. If the high-pressure system was not primed after the last service, this code will log.
B. Prime the fuel system.
C. Apply electrical power to the engine.
D. Connect Cat ET.
E. Clear the fault E1220 or 5585-17 code.
F. Start the engine.
Code
Result: An E1220 or a 5585-17 code came active after clearing.
Proceed to Test Step 4.
Result: An E1220 or a
