Troubleshooting Test Steps Values Results
1. Determine the Code
A. Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Determine if a diagnostic trouble code is present.
Diagnostic trouble code
Result: A E198 or 5580 code is present.
Proceed to Test Step 2.
Result: A code other than E198 or 5580 code is present.
Troubleshoot the code. Refer to the proper troubleshooting procedure.
2. Check the Fuel Level in the Tank
A. Visually inspect the fuel level in the fuel tank. Ensure that the fuel tank contains enough fuel in order to operate the engine.
B. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
Fuel level
Result: The fuel level is OK.
Proceed to Test Step 3.
Result: The fuel level is not OK.
Fill the tank. Verify that the problem has been resolved. If the problem is not resolved, proceed to Test Step 3.
3. Inspect the Fuel System for Leaks
A. Perform a visual inspection of the fuel system. Verify that there are no fuel leaks. Inspect the fuel lines from the fuel transfer pump to the secondary fuel filter base for restrictions.
Leaks
Result: No leaks were found.
Proceed to Test Step 4.
Result: Leaks were found in the fuel system.
Repair the leaks. Verify that the problem is resolved. If the problem is not resolved, proceed to Test Step 4.

4. Check the Fuel Pressure Sensor
A. Record the fuel pressure from Cat ET. Record the data in Table 4.
B. Remove fuel pressure sensor (3).
C. Install an 8T-7860 Connector into the port of the pressure sensor (3).
D. Install the 110-6349 Fitting as onto the 8T-7860 Connector.
E. Install an 8T-0855 Pressure Gauge onto a 6V-3990 Coupler.
F. Install the 6V-3990 Coupler onto the 110-6349 Fitting as.
G. Record the fuel pressure on the pressure gauge. Record the data in Table 4.
Fuel Pressure Sensor
Result: The gauge value of the fuel pressure is within 137 kPa (20 psi) of the fuel pressure reading shown in ET.
Proceed to Test Step 5.
Result: The gauge value of the fuel pressure is not within 137 kPa (20 psi) of the fuel pressure reading shown in ET.
Replace the pressure sensor. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 5.

Troubleshooting Test Steps Values Results
5. Verify that the Fuel Pressure Is Within Specifications
A. Verify that the recorded fuel pressure is above the minimum acceptable fuel specifications. Refer to Table 6 for the minimum acceptable specifications.
Fuel pressure
Result: The fuel pressure is above the minimum acceptable fuel specifications.
Proceed to Test Step 7.
Result: The fuel pressure is not above the minimum acceptable fuel specifications.
Proceed to Test Step 6.
6. Replace the Fuel Filters
A. Replace the primary filter, the secondary filter, and the tertiary fuel filters.
The fuel system will need to be primed after the filters are replaced.
B. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the fuel pressure is above the minimum acceptable pressure specifications. Refer to Table 6 for the proper specifications.
Fuel filters
Result: The fuel pressure meets the minimum acceptable fuel pressure specifications.
Return the engine to service.
Result: The fuel pressure does not meet the minimum acceptable fuel pressure specifications.
Proceed to Test Step 7.
7. Check for Air in the Fuel System
A. Check for air in the fuel. Refer to Systems Operation/Testing and Adjusting, "Air in Fuel - Test" for the proper procedure.
Air
Result: Air is in the system.
Refer to Systems Operation/Testing and Adjusting, "Air in Fuel - Test" for the proper repairs.
If the problem is not resolved, proceed to Test Step 8.
