Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check the Fuel Pressure Sensor
A. Connect Cat ET.
B. Record the fuel pressure from Cat ET.
Use a mechanical gauge to check the system fuel pressure. Refer to Testing and Adjusting, "Fuel Pressure (Gas System)" for additional information.
C. Record the fuel pressure on the pressure gauge.
Note: If a mechanical gauge is not available, determine if the fuel pressure reading on Cat ET is reasonable.
Sensor
Result: The gauge value of the fuel pressure is reasonable when compared to the fuel pressure reading shown in Cat ET.
Proceed to Test Step 3.
Result: The gauge value of the fuel pressure is not reasonable when compared to the fuel pressure reading shown in Cat ET.
Repair: Replace the pressure sensor. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position.
Verify that the repair eliminated the problem.
3. Check the Fuel Filter
A. Measure the fuel filter's differential pressure according to Operation and Maintenance Manual, "Fuel System Fuel Filter Differential Pressure - Check".
Fuel Filter
Result: The fuel filter is OK.
Proceed to Test Step 4.
Result: The fuel filter is NOT OK.
Repair: Replace the filter element.
If the problem is not resolved, proceed to Test Step 4.
Gaseous fuel is present. Personal Injury or Death can result from an open flame or spark igniting the gaseous fuel causing an explosion and/or fire. Always use a gas detector to determine the presence of gaseous fuel when maintaining and servicing. Contact your local gas provider immediately for assistance in the event of a leak.
Table 3
4. Check the Fuel System
A. Obtain a fuel analysis.
Note: If the quality of the gas is inconsistent, obtain several analyses over a period of time.
B. Enter the data into Caterpillar Software, LERW4485, "Gas Engine Rating Pro (GERP)".
C. Verify that the fuel supply pressure is adequate and stable.
D. Verify that the size of the fuel line is sufficient.
E. Inspect the fuel system for leaks.
Note: Always use a gas detector to determine the presence of gaseous fuel. Contact your local provider of gas immediately for assistance.
F. Inspect the following fuel system components:
- Fuel filter
- Gas pressure regulator
- Gas shutoff valve
- Gas shutoff valve solenoid
Fuel System
Result: The fuel system is OK.
Proceed to Test Step 5.
Result: The fuel system is NOT OK.
Repair: Repair or replace damaged fuel system components.
Use Cat ET to program the results for the "Fuel Specific Heat Ratio", "Fuel Quality", and "Gas Specific Gravity" parameters. Refer to Systems Operation, "Electronic Control System Parameters" for additional information.
Program the "Fuel Quality" parameter to the average value of the LHV. Adjust the engine operation according to Testing and Adjusting, "BTU and Precombustion Chamber Adjustments".
If the problem is not resolved, proceed to Test Step 5.
5. Adjust the Gas Pressure Regulator
A. Adjust the gas pressure regulator. Refer to Testing and Adjusting, "Fuel Pressure (Gas System)".
10.3 to 24.1 kPa or 1.5 to 3.5 psig
Result: The gas pressure is NOT OK.
Repair: Adjust the gas pressure regulator. Refer to Testing and Adjusting, "Fuel Pressure (Gas System)" for additional information.
If the gas pressure regulator cannot be adjusted to the correct setting, repair the regulator or replace the regulator.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
