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 Electronic Control Module (ECM) before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if a diagnostic trouble code is present.
   
Codes    
Result: An E1218 (2) code is present.
Proceed to Test Step 2.
Result: A code other than a E1218 (2) code is present.
Repair: Troubleshoot the code. Refer to the proper troubleshooting procedure.

2. Check Fuel Pressure Sensor "A"
A. Record the unfiltered fuel pressure from Cat ET. Record the value in Table 6.
B. Remove fuel pressure sensor "A" (2) .
C. Install a 5P-1318 Adapter into the port of the pressure sensor "A" (2) .
D. Install the 123-0783 Fluid Sampling Valve Gp onto the 5P-1318 Adapter .
E. Install a 8T-0855 Pressure Gauge onto a 6V-3990 Coupler .
F. Install the 6V-3990 Coupler onto the 123-0783 Fluid Sampling Valve Gp .
G. Record the fuel pressure from the pressure gauge. Record the pressure in Table 6.
   
Pressure Sensor    
Result: The gauge value of the fuel pressure is within 69 kPa (10 psi) of the unfiltered fuel pressure reading shown in Cat ET.
Proceed to Test Step 3.
Result: The gauge value of the fuel pressure is not within
69 kPa (10 psi) of the unfiltered fuel pressure reading shown in Cat ET.
Repair: Replace the pressure sensor. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 3.

3. Inspect the Fuel Supply and Return Lines
A. Visually inspect the fuel lines between the primary filter base and the inlet to the fuel injection pump. Also, inspect the fuel cooler, if equipped. Inspect the fuel return line from the head to the fuel tank. Inspect the lines for restrictions, pinching, and swelling. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
   
Lines    
Result: The fuel lines and the cooler (if equipped) are OK.
Proceed to Test Step 4.
Result: The fuel lines and the cooler (if equipped) are not OK.
Repair: Make the necessary repairs. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 4.
