Which Generate This Code:The Electronic Control Module (ECM) detects the following conditions:363-1
The fuel temperature is at least 80 °C (176 °F) for 30 seconds.
The engine has been running for at least three minutes.Note: This event can be triggered from either of the two fuel temperature sensors on the marine auxiliary application.System Response:363-1The ECM will trigger a snapshot. The event code will be logged once the fuel temperature drops below 78 °C (172 °F) for four seconds.363-1NoneTest Step 1. Evaluate the Conditions
Evaluate the environmental conditions.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. Also, an overheated engine could cause the fuel temperature to reach the trip level.Expected Result:The reason for the high fuel temperature was determined.Results:
OK - The reason for the high fuel temperature was determined.Repair: Avoid operating the machine in conditions that could cause the engine and the fuel to overheat. Damage to the engine and injectors could result.STOP
