Diagnostic Codes Table    
Code and Description    Conditions which Generate this Code    System Response    
110-3 Engine Coolant Temperature Sensor voltage above normal     The engine's Electronic Control Module (ECM) detects signal voltage that is more than 4.95 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.     The code is logged if the engine has been running for more than 7 minutes. The ECM uses the last valid engine coolant temperature. If the diagnostic code is active at start-up, the ECM will use intake manifold temperature. If intake manifold air temperature is not valid, the ECM will default to 90 °C (194 °F) for engine coolant temperature. The ECM will activate the cooling fan after this code has been active for more than 8 seconds.    
110-4 Engine Coolant Temperature Sensor voltage below normal     The ECM detects signal voltage that is less than 0.2 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.    
172-3 Intake Manifold Air Temperature Sensor voltage above normal     The engine's ECM detects signal voltage that is more than 4.95 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.     The ECM will log the diagnostic code. The ECM will flag the intake manifold air temperature as invalid data and the intake manifold air temperature is set to a default value of
40 °C (104 °F).    
172-4 Intake Manifold Air Temperature Sensor voltage below normal     The ECM detects signal voltage that is less than 0.2 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.    
174-3 Fuel Temperature Sensor voltage above normal     The engine's Electronic Control Module (ECM) detects signal voltage that is more than 4.95 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.     The code is logged. The ECM will flag the fuel temperature as invalid data and the fuel temperature is set to a default value of
40 °C (104 °F).    
174-4 Fuel Temperature Sensor voltage below normal     The ECM detects signal voltage that is less than 0.2 VDC for 2 seconds.
The ECM has been powered for at least 2 seconds.    
175-3 Engine Oil Temperature Sensor voltage above normal     The engine's Electronic Control Module (ECM) detects signal voltage that is more than 4.95 VDC for 8 seconds.
The ECM has been powered for at least 2 seconds.     The code is logged. The ECM will flag the oil temperature as invalid data and the oil temperature is set to the engine coolant temperature.    
175-4 Engine Oil Temperature Sensor voltage below normal     The ECM detects signal voltage that is less than 0.2 VDC for 2 seconds.
The ECM has been powered for at least 2 seconds.    
2117-3 Intake Valve Actuation System Oil Temperature Sensor : Voltage Above Normal     The ECM detects signal voltage is above the expected value..     The code is logged.    
2117-4 Intake Valve Actuation System Oil Temperature Sensor : Voltage Below Normal     The ECM detects signal voltage is below the expected value..     The code is logged.    System OperationUse this procedure to troubleshoot any suspect problems with the following sensors:
Coolant temperature sensor
Intake manifold air temperature sensor
Fuel temperature sensor
Engine oil temperature sensorThe sensor signal for the passive sensor is routed from the ECM to terminal 1 of each sensor connector. The sensor return for the passive sensors is routed from the ECM to terminal 2 of each sensor connector.

Remove electrical power from the ECM.
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Restore electrical power to the ECM.
Monitor the diagnostic codes on Cat ET. Check and record any diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Determine if a diagnostic code has occurred several times.Note: A diagnostic code that is logged several times is an indication of an intermittent problem. Most intermittent problems are the result of a poor connection between a socket and a pin in a connector or of a poor connection between a wire and a terminal.
Determine if the problem is active and related to one of the following diagnostic codes:
-3
-4
Remove electrical power from the ECM.Expected Result:A diagnostic code is not active.Results:
OK - A diagnostic code is not active.Repair: The problem may be intermittent. If the problem is intermittent, refer to Troub
