WASHER 1388864 - Caterpillar

Use this procedure in order to troubleshoot high oil temperature or use this procedure if one of the following event codes is active.
Table 1
Event Code
Code and Description Conditions which Generate this Code System Response
E197(1) High Engine Oil Temperature The engine oil temperature has exceeded the trip point and the delay time has expired. The code is logged.
E197(2) High Engine Oil Temperature The code is logged.
Engine power is derated.
E197(3) High Engine Oil Temperature The code is logged.
The engine is shut down. If the engine is shut down due to a high engine oil temperature, the power to the engine Electronic Control Module (ECM) must be cycled in order to restart the engine.Probable Causes
Diagnostic codes and event codes
Coolant temperature is high

Repair: Troubleshoot any associated codes before continuing with this test.
Result: An E197 code is present.
Proceed to the next step.
Result: No active codes
STOP
2. Check the Engine Coolant Temperature
A. Determine if a high coolant temperature condition exists.
Temperature
Result: The temperature is OK.
Result: The temperature is NOT OK.
Repair: Repair refer to the symptom Troubleshooting, "Coolant Temperature Is High"injectors.
3. Check the Engine Oil Level
Level
Result: The level is OK.
Proceed to the next step.
Result: The level is NOT OK.
Repair: Add oil and repair any leaks.
If the problem is not resolved, proceed to the next step.
4. Check the Engine Oil Cooler Bypass Valve
A. Ensure that the bypass valve is not stuck in the open position. Clean the bore for the valve.
Inspect the components of the engine oil cooler bypass valve for damage.
Valve
Result: The valve is OK.
Proceed to the next step.
Result: The valve is NOT OK.
Repair: Free the valve or replace the valve.
If the problem is not resolved, proceed to the next step.
