Description Default Conditions which Generate this Code System Response
E363(1) High Fuel Supply Temperature The fuel temperature is above an acceptable level. If equipped, the warning light will illuminate.
The code is logged. Probable Causes
Fuel return pressure regulating valve
Fuel level
Fuel injector
Fuel lines
Overheated engine
Fuel temperature sensorsRecommended Actions
Fuel Return Pressure Regulating Valve
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
Do not loosen any high pressure fuel lines when the engine is running. The high pressure in the fuel lines can cause personal injury or death. Wait 60 seconds after the engine has stopped to allow pressure to purge before any service or repair is performed on the engine fuel lines.
An improperly operating fuel pressure regulating valve may cause high fuel temperature. If a problem is suspected, inspect the return fuel pressure regulating valve for contamination or debris. Clean any contamination or debris that may keep the regulating valve from operating properly. If debris is present, find the source of the contamination. If the return fuel pressure regulating valve is suspect, replace the valve assembly.Check the complete fuel system. Refer to Systems Operation/Testing and Adjusting, "Fuel System Pressure - Test".Fuel Level
Ensure that the fuel tank contains enough fuel. As the fuel tank level decreases, the fuel temperature generally increases. Fuel Injector
Perform the "Cylinder Cutout Test" on Cat ET in order to identify any injectors that might be misfiring.Verify that all of the trim files are correctly loaded into the ECM. Refer to Troubleshooting, "Injector Trim File - Install".Perform the "Cylinder Cutout Test" on Cat ET in order to verify that the injectors are correctly firing.Fuel Lines
Verify that the fuel supply valve (if equipped) is in the full open position.Restricted fuel return lines may produce very high fuel temperatures. Ensure that the fuel return flow to the fuel tank is not obstructed.Visually inspect the fuel supply line between the secondary fuel filter base and the inlet to the cylinder head. Check for pinching, restrictions and swelling. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect".Overheated Engine
The fuel is returned through a passage in the cylinder head. Abnormally high ambient air temperature could cause the fuel temperature to reach the trip level. An overheated engine could cause the fuel temperature to reach the trip level.Fuel Temperature Sensor
Start the engine. Run the engine until normal operating temperature is achieved. Use Cat ET to monitor the following parameters:
"Fuel Temperature"
"Fuel Rail Temperature"Check the value of each parameter while the engine is at normal operating temperature. Install a new temperature sensor and record the fuel temperature. Use Cat ET to compare the fuel temperature against the recorded fuel temperature. If the recorded temperature is within 5° C (41° F) of the temperature shown in Cat ET the sensor is OK. Otherwise, replace the sensor.If necessary, troubleshoot the circuit and the fuel temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".Perform the "Cylinder Cutout Test" on Cat ET in order to identify any injectors that might be misfiring.Verify that all of the trim files are correctly loaded into the ECM. Refer to Troubleshooting, "Injector Trim File - Install".Perform the "Cylinder Cutout Test" on Cat ET in order to verify that the injectors are correctly firing.
