Use this procedure in order to troubleshoot high fuel temperature. Use this procedure if the following event code is active. Refer to Troubleshooting, "Event Codes" for information about event codes and the default trip points for this code. You must access the engine monitoring system on AVSpare Electronic Technician (ET) in order to view the current trip points for this code. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".

Code and Description     Conditions which Generate this Code     System Response    
E363(1) High Fuel Supply Temperature     The fuel temperature is above the trip point temperature.     The code is logged.    

Probable Causes

  • Fuel pressure regulating valve

  • Fuel level

  • Fuel lines

  • Overheated engine

Recommended Actions

Fuel Pressure Regulating Valve

An improperly operating fuel pressure regulating valve may cause high fuel temperature. If a problem is suspected, inspect the return fuel pressure regulating valve. Clean any contamination or debris that may keep the regulating valve from operating properly. If debris is present, find the source of the contamination. Replace the return fuel pressure regulating valve if the valve is worn or damaged.

Fuel Level

Ensure that the fuel tank contains enough fuel. As the fuel tank level decreases, the fuel temperature generally increases.

Fuel Lines

Restricted fuel return lines may produce very high fuel temperatures. Ensure that the fuel return flow to the fuel tank is not obstructed.

Overheated Engine

The fuel is supplied to the injectors 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.
