There are no performance effects.198(2)
The engine power is derated.198(3)
The engine is shut down.Test Step 1. Check the Fuel System's Components
Inspect the pressure relief valve that is in the body of fuel transfer pump. Check for damage to the spring or to the valve assembly.
Verify that the pressure regulating valve in the fuel manifold is operating correctly. Check for damage or for dirt in the valve assembly.
Check the return line from the fuel filter base to the fuel tank for damage or collapse. Expected Result:There is a problem in the pressure relief valve, in the pressure regulating valve, or in the return line to the fuel tank.Results:
OK - A problem was found in the pressure relief valve, in the pressure regulating valve, or in the return line to the fuel tank.Repair: Make the necessary repairs. Verify that the repair eliminates the problem.Refer to Systems Operation/Testing and Adjusting.STOP
Not OK - A mechanical problem has not been found with the fuel system.Repair: If an electrical problem with the sensor circuit is suspected, refer to the diagnostic functional test Troubleshooting, "Engine Pressure Sensor Open or Short Circuit - Test".STOP
