Troubleshooting Test Steps    Values    Results    
1. Determine the Code
A. Connect Cat® Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if a diagnostic trouble code is present or an associated code is present.
   
Codes
   
Result: An E198 or 5580 code is present.
Proceed to Test Step 2.
Result: An associated code is present.
Repair: Troubleshoot the associated code. Refer to the proper troubleshooting procedure.
STOP
   
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.
Repair: 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. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
   
Fuel System    
Result: No leaks were found.
Proceed to Test Step 4.
Result: Leaks were found in the fuel system.
Repair: Repair the leaks. Verify that the problem is resolved.
If the problem is not resolved, proceed to Test Step 4.
   Note: Cold weather adversely affects the characteristics of the fuel. Refer to the engine Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation.

Troubleshooting Test Steps    Values    Results    
4. Check the Fuel Pressure Sensor
A. Record the fuel pressure from Cat ET. Record the value in Table 6.
B. Remove the fuel pressure sensor .
C. Install a 8t-7860 Connector into the port of the pressure sensor .
D. Install the 110-6349 Fitting As onto the 8t-7860 Connector .
E. Install a 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 from Cat ET and on the pressure gauge. Record the data in Table 6.
   
Pressure Sensor    
Result: The gauge value of the fuel pressure is within 69 kPa (10 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
69 kPa (10 psi) of the fuel pressure reading shown in ET.
Repair: Replace the pressure sensor. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 5.
