The service tool displays "Error Indicator" on the status screen for this parameter.
105-4 Engine Intake Manifold #1 Temperature : Voltage Below Normal The ECM detects a signal voltage that is less than 0.2 VDC for eight seconds.
110-3 Engine Coolant Temperature : Voltage Above Normal The ECM detects a signal voltage that is more than 4.95 VDC for ten seconds. The code is logged.
The amber warning lamp is illuminated.
The service tool displays "Error Indicator" on the status screen for this parameter.
110-4 Engine Coolant Temperature : Voltage Below Normal The ECM detects a signal voltage that is less than 0.2 VDC for eight seconds.
175-3 Engine Oil Temperature 1 : Voltage Above Normal The ECM detects a signal voltage that is more than 4.95 VDC for ten seconds. The code is logged.
The amber warning lamp is illuminated.
The service tool displays "Error Indicator" on the status screen for this parameter.
175-4 Engine Oil Temperature 1 : Voltage Below Normal The ECM detects a signal voltage that is less than 0.2 VDC for eight seconds. System OperationUse this procedure to troubleshoot any suspect problems with the temperature sensors for the engine.The sensor signal for the passive sensor is routed from the ECM to terminal 1 of the sensor connector. The sensor return for the passive sensors is routed from the ECM to terminal 2 of the sensor connector.The most likely cause of a code is a problem with an electrical connector or wiring. The least likely cause of a code is the ECM.

Turn the engine control to the OFF position. Remove electrical power from the engine.
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Restore electrical power to the engine. Turn the engine control to the STOP position.
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. The poor connection can occur between a socket and a pin in a connector or between a wire and a terminal.
Determine if the problem is active and related to one of the following failure modes for the analog passive sensor:
-3 code
-4 code
Turn the engine control to the OFF position. Remove electrical power from the engine. Expected Result:A diagnostic code is not active.Results:
OK - A diagnostic code is not active.Repair: There may be an intermittent electrical problem in the harness or in a connector. If an intermittent electrical problem is suspected, refer to Testing and Adjusting, "Electrical Connectors - Inspect" for information that is related to troubleshooting these problems.STOP
Active -3 - An active -3 diagnostic code is present. The ECM detects an open in the circuit for the sensor. Proceed to Test Step 2.
Active -4 - An active -4 diagnostic code is present. Proceed to Test Step 4.Test Step 2. Check for Battery Voltage on the Signal Wire
Restore electrical power to the engine. Turn the engine control to the STOP position.
Measure the voltage on the harness side of the sensor connector between pin 1 and engine ground for the suspect sensor.
Turn the engine control to the OFF position. Remove electrical power from the engine. Expected Result:The signal voltage is less than battery voltage.Results:
OK - The signal voltage is less than battery voltage. The circuit for the signal is not shorted to the +Battery. Proceed to Test Step 3.
Not OK - The signal voltage is equal to battery voltage.Repair: There is a short circuit to the +Battery in the harness. Repair the wiring harness or replace the wiring harness. Verify that the repair has resolved the original problem.STOPTest Step 3. Create a Short Circuit at the Connector for the Suspect Sensor
Disconnect the harness connector for the suspect sensor.
Fabricate a jumper wire that is long enough to create a test circuit across the harness side of the sensor connector. Crimp connector pins to each end of the jumper wire.
Install the jumper wire between terminal 1 (sensor signal) and terminal 2 (sensor return) at the sensor connector.
Restore electrical power to the engine. Turn the engine control to the STOP position.
Access the "Active Diagnostic Code" screen on Cat ET. Check for an active -4 diagnostic code for the suspect sensor. Wait at least 30 seconds in order for the diagnostic codes to become active.
Turn the engine control to the OFF/RESET position. Remove electrical power from the engine. Expected Result:A -4 diagnostic code is now active for the suspect sensor.Results:
OK - A -4 diagnostic code became active with the jumper wire in place.Repair: A -3 diagnostic code was active before creating the short at the sensor connector. A -4 diagnostic code became active after creating the sho
