1318-0
Engine Exhaust Temperature Bank Imbalance : High - most severe (3) E2163 (3)
High Turbocharger Turbine Intake Differential Temperature There is a temperature differential greater than a threshold between the left and right cylinder banks.
1318-15
Engine Exhaust Temperature Bank Imbalance : High - least severe (1) E2163 (1)
High Turbocharger Turbine Intake Differential Temperature There is a temperature differential greater than a threshold between the left and right cylinder banks.
1318-16
Engine Exhaust Temperature Bank Imbalance : High - moderate severity (2) E2163 (2)
High Turbocharger Turbine Intake Differential Temperature There is a temperature differential greater than a threshold between the left and right cylinder banks. If the engine is shut down due to an exhaust temperature differential is high event, the power to the engine Electronic Control Module (ECM) must be cycled to restart the engine.Probable Causes

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Inspect the Exhaust System
A. Remove electrical power from the engine.
B. Inspect the following exhaust components:
- Lines
- Hoses
- Bellows
- Clamps
- Exhaust manifolds
Note: Verify that all the bellows have the correct orientation. Ensure that the arrow on the bellows is pointing in the direction of the exhaust flow.
Exhaust System
Result: The exhaust system is OK.
Proceed to Test Step 3.
Result: The exhaust system is NOT OK.
Repair: Repair or replace damaged exhaust components.
If the problem is not resolved, proceed to Test Step 3.
3. Test the Fuel Injectors
A. Connect Cat ET.
B. Use Cat ET to perform the following fuel injector tests:
- "Injector Solenoid Test"
- "Cylinder Cutout Test"
Refer to Troubleshooting, "Cat ET Service Features" for additional information.
Fuel Injectors
Result: The tests were successful.
Proceed to Test Step 4.
Result: The tests were not successful.
Repair: Diagnose the problem. Repair or replace damaged components.
If the problem is not resolved, proceed to Test Step 4.
4. Inspect the Turbochargers for Damage
A. Remove electrical power from the engine.
B. Inspect the following turbocharger components for damage:
- Compressor wheel
- Compressor housing
- Turbine wheel
- Turbine housing
- Temperature sensor
Turbocharger
Result: The turbochargers are OK.
Proceed to Test Step 5.
Result: There is a problem with the turbochargers and/or temperature sensors.
Repair: Repair or replace damaged turbocharger or temperature sensor.
If the problem is not resolved, proceed to Test Step 5.
5. Inspect the Valve Train Components
A. Remove the valve mechanism cover and the camshaft covers.
B. Check the valve lash. Refer to Testing and Adjusting, "Valve Lash - Adjust" for additional information.
C. Check the following valve train components for damage:
- Camshaft
- Valve rotocoil
- Valve springs
- Camshaft followers
- Rocker shaft
- Bridges
- Pushrods
- Injectors
D. Check for valves that do not move freely. Remove the cylinder head and inspect the valves. Refer to the Disassembly and Assembly manual for additional information.
Valve Train
Result: The valve train components are damaged.
Repair: Repair or replace damaged valve train components.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
