175-4 Engine Oil Temperature 1 : Voltage Below Normal The ECM detects signal voltage that is less than 0.2 VDC for 8 seconds. System OperationUse this procedure to troubleshoot any suspect problems with the following sensors for the primary ECM:
Coolant temperature sensor (Primary & Secondary ECM)
Intake manifold air temperature sensor (Primary & Secondary ECM)
Engine oil temperature sensor (Primary ECM)
Turbocharger inlet temperature sensor (Primary ECM)
SCAC temperature sensor (Primary ECM)This engine utilizes a redundant control system in the case of an ECM failure. If the primary ECM fails, the secondary ECM provides for engine control and engine system monitoring. The secondary ECM utilizes several additional active sensors to monitor engine operation. The following sensors can be found on the engine and are only utilized by the secondary ECM during a failure of the primary ECM:When troubleshooting these sensors, ensure that the secondary ECM is controlling the engine. except for the secondary intake manifold air temperature sensor, each secondary sensor utilizes the same diagnostic code as the primary version of the sensor. The troubleshooting procedure for each secondary passive sensor is the same as the troubleshooting for the primary passive sensors.

Troubleshooting Test Steps Values Results
1. Check for "Active" or "Logged" Diagnostic Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector.
B. Restore the electrical power to the ECM.
C. 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.
D. Determine if the problem is active and related to one of the following diagnostic codes:
-3
-4
Codes
Results: No diagnostic codes are active at this time.
Repair: The problem may be intermittent. If the problem is intermittent refer to Troubleshooting, "Electrical Connectors - Inspect"
Results: An active -3 diagnostic code is present.
Proceed to Test Step 2
Results: An active -4 diagnostic code is present.
Proceed to Test Step 4
2. Check for a Short to the +Battery at the Sensor Connector
A. Measure the voltage on the harness side of the sensor connector between pin 1 and pin 2 for the suspect sensor.
+Battery
Results: The supply voltage is less than Battery voltage.
Proceed to Test Step 3
Results: The supply voltage is equal to Battery voltage.
Repair: There is a short in the harness to the +Battery. Repair the wiring.
Verify that the repair eliminated the problem.
