Diagnostic Codes Table
Description Conditions which Generate this Code System Response
1181-3 Engine Turbocharger 2 Turbine Inlet Temperature : Voltage Above Normal The ECM detects a duty cycle that is greater than 96 percent for ten seconds. The code is logged.
If the signal from the other exhaust temperature sensor is OK, the signal from that sensor is used. If the signal from the other exhaust temperature sensor is not OK, a default value is used.
1181-4 Engine Turbocharger 2 Turbine Inlet Temperature : Voltage Below Normal The ECM detects a duty cycle that is less than 4 percent for ten seconds.
1181-8 Engine Turbocharger 2 Turbine Inlet Temperature : Abnormal Frequency, Pulse Width, or Period The ECM detects a sensor frequency that is greater than 600 Hz or less than 400 Hz.
1180-3 Engine Turbocharger 1 Turbine Inlet Temperature : Voltage Above Normal The ECM detects a duty cycle that is greater than 96 percent for ten seconds. The code is logged.
If the signal from the other exhaust temperature sensor is OK, the signal from that sensor is used. If the signal from the other exhaust temperature sensor is not OK, a default value is used.
1180-4 Engine Turbocharger 1 Turbine Inlet Temperature : Voltage Below Normal The ECM detects a duty cycle that is less than 4 percent for ten seconds.
1180-8 Engine Turbocharger 1 Turbine Inlet Temperature : Abnormal Frequency, Pulse Width, or Period The ECM detects a sensor frequency that is greater than 600 Hz or less than 400 Hz. System OperationUse this procedure to troubleshoot any suspect problems with the sensor for the left turbocharger turbine inlet temperature or the right turbocharger turbine inlet temperature.The Pulse Width Modulated Sensor (PWM) provides a signal to the engine ECM. The PWM signal is used to represent certain engine operating conditions. The sensors receive 8.0 0.4 VDC from a regulated power supply.The ECM performs an automatic calibration of these sensors whenever the ECM is powered and the engine has been off for at least five seconds.The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.The following components can cause problems with the power supply:
Electrical connector or wiring
Sensor
ECMThe most likely cause of a problem is a problem with an electrical connector or wiring. The least likely cause is a problem with the ECM.

(Terminal 3) Signal Test Step 1. Check for an "Active" Diagnostic Code
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
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. Many intermittent problems are the result of a bad connection between a socket and a pin in a connector. A bad connection between a wire and a terminal may also cause intermittent problems.
Look for one or more of the following diagnostic codes that are active or logged:
-03
-04
-08Expected Result:No diagnostic code is active for the exhaust temperature sensors.Results:
OK - No diagnostic codes are active.Repair: There may be an intermittent problem in the harness or in a connector. If an intermittent problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct procedures for inspecting electrical connectors.STOP
Not OK - One of the diagnostic codes that are listed above are active or logged. The ECM detects a problem in one of the circuits for the exhaust temperature sensors. Proceed to Test Step 2.Test Step 2. Check the Digital Supply Voltage at the Sensor Connector
Turn the main disconnect switch to the OFF position.
