Note: If 633-7 Pressure Limiter Emergency Open has occurred, replacement of the common rail manifold and high-pressure tubes are required. Refer to the Disassembly and Assembly, "Fuel Manifold (Rail) - Remove and Install". After replacing, the “Fuel Pump Calibration” must be performed in Cat ET. Refer to “Cat ET Service Features” for this calibration.
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.

Troubleshooting Test Steps Values Results
1. Diagnostic Codes
A. Establish communication with Caterpillar Electronic Technician (Cat ET). Check for active diagnostic codes.
Diagnostic Codes
Result: Active diagnostic codes are present.
Troubleshoot the diagnostic code.
Result: Active diagnostic codes are not present.
Proceed to Test Step 2.
2. Fuel Rail Pressure
A. Check the fuel rail pressure in Cat Electronic Technician (Cat ET)
Low Idle: 39989 kPa (5800 psi) to 49642 kPa (7200 psi)
Accelerating to Hi Idle: 96526 kPa (14000 psi) to 131000 kPa (19000 psi)
Hi Idle: 96526 kPa (14000 psi) to 131000 kPa (19000 psi)
C3.8 Tier 4 Final / Stage IV (ONLY)
Low Idle: 35-60 MPa (5100-8700 psi)
Accelerating to Hi Idle: 0-100% (During acceleration) Max value 155 MPa (22500)
No-Load Max speed: 75 to 155 MPa (10900 to 22400 psi)
Result: The fuel pressure is not within specification.
Refer to Testing and Adjusting, "Air in Fuel - Test"
Result: The fuel pressure is within specification.
Proceed to Test Step 3.
3. Check the Fuel System
Refer to Systems Operation/Testing and Adjusting, "Fuel System" for additional information.
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the vent in the fuel cap is not filled with debris.
C. Inspect the fuel system for external leaks.
D. Check that there is no air in the clear primary fuel filter. Refer to Systems Operation/Testing and Adjusting, Low-Pressure Fuel System - Test.
E. Check fuel quality. Refer to Systems Operation/Testing and Adjusting, "Fuel Quality - Test" for the proper procedure. Check the fuel tank for debris or foreign objects which may block the fuel supply.
F. Check for the proper operation of the fuel transfer pump. Replace the pre-filter if excessive contamination or if the maintenance interval is exceeded. Refer to Systems Operation/Testing and Adjusting, "Fuel System" for test information.
Fuel System
Result: The fuel system is OK.
Proceed to Test Step 4.
Result: The fuel system is not OK.
Replace the fuel filters. Clean the primary filter/water separator of debris. Refer to the Operation and Maintenance Manual for details.
4. Check the Fuel Rail Pressure Sensor
Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test" for more information.
Fuel Rail Pressure Sensor
Result: The fuel rail pressure sensor is OK.
Proceed to Test Step 5.
Result: The fuel pressure sensor is NOT working properly.
Repair: Replace the fuel rail pressure sensor and verify that the problem has been corrected.
5. Check SCV Resistance
(Does not apply to C3.8 Tier 4 Final / Stage IV)
A. Check resistance at the SCV terminals. At 20° C (68° F) the resistance should approximately be 2.1 ohms.
B. With the plug connected to the SCV, check resistance at the ECM connector to check the harness. The resistance should be approximately 2.1 ohms.
SCV Resistance
