Event Code
Description Conditions which Activate the Code System Response
E243 (1) High Left Turbo Turbine Outlet Temperature The temperature at the outlet for the left turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E243 (3) High Left Turbo Turbine Outlet Temperature The shutdown output is activated. The code is logged. The engine is shut down.
E244 (1) High Right Turbo Turbine Outlet Temperature The temperature at the outlet for the right turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E244 (3) High Right Turbo Turbine Outlet Temperature The shutdown output is activated. The code is logged. The engine is shut down.
E245 (1) High Right Turbo Turbine Inlet Temperature The temperature at the inlet for the right turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E245 (3) High Right Turbo Turbine Inlet Temperature The fuel is shut off. The shutdown output is activated. The code is logged. The engine is shut down.
E246 (1) High Left Turbo Turbine Inlet Temperature The temperature at the inlet for the left turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E246 (3) High Left Turbo Turbine Inlet Temperature The fuel is shut off. The shutdown output is activated. The code is logged. The engine is shut down. Note: Refer to Troubleshooting, "Engine Monitoring System" for information on trip points and delay times.Probable Causes
High inlet air temperature
Incorrect base timing
Exhaust restriction
A buildup of deposits in the cylinder or internal oil leaksRecommended Repairs
Check for Event Codes for High Inlet Air Temperature
Use the Caterpillar Electronic Technician (ET) to check for the following event codes:
E027 (1) High Inlet Air Temperature Warning
E368 (1) High Inlet Air Temperature Warning
E025 (2) High Inlet Air Temperature Derate
E368 (2) High Inlet Air Temperature Derate
E026 (3) High Inlet Air Temperature Shutdown
E368 (3) High Inlet Air Temperature ShutdownIf either code is active or logged, refer to Troubleshooting, "Inlet Air Temperature Is High".Check the Base Timing
Verify that the base timing is correct. Refer to Systems Operation/Testing and Adjusting, "Ignition Timing - Adjust".Measure the Exhaust Restriction
Measure the exhaust restriction during engine operation with a load. For data that is specific to the engine, refer to the Technical Marketing Information.Investigate the cause of the exhaust restriction. Perform adjustments and/or make repairs, as needed.Check for Deposits in the Cylinder and Check for Internal Oil Leaks
Use a borescope to inspect the cylinders. Look for the following conditions:
Deposits on the valve seats
Deposits on the valve faces
Deposits on the cylinder walls that are above the upper limit of the piston stroke
Signs of internal oil leaksOther signs of internal oil leaks include high oil consumption and blue smoke.Note: Excessive deposits contribute to guttering of the valves.If excessive deposits and/or signs of internal oil leaks are found, investigate the cause of the condition. Make repairs, as needed.
