Engine Turbocharger 1 Turbine Inlet Temperature : Voltage Above Normal 3908-3
Engine Turbocharger #1 Turbine Intake Temperature Sensor : Voltage Above Normal 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 of 0 °C (32 °F) is used.
The code is logged.
1180-4
Engine Turbocharger 1 Turbine Inlet Temperature : Voltage Below Normal 3908-4
Engine Turbocharger #1 Turbine Intake Temperature Sensor : Voltage Below Normal 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 of 0 °C (32 °F) is used.
The code is logged.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: A -3 code is active or logged.
Proceed to Test Step 2.
Result: A -4 code is active or logged.
Proceed to Test Step 3.
Result: A -8 code is active or logged.
Proceed to Test Step 5.
2. Create a Short at the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor with the active -3 code.
C. Install the jumper wire between the following terminals at the sensor connector:
- Pin 2 (sensor return) and Pin 3 (sensor signal)
D. Connect Cat ET.
E. Use Cat ET to monitor the following:
- -4 code
F. Turn the keyswitch to the OFF position.
Create a Short
Result: A -4 code became active.
Repair: The wiring harness is OK. Replace the sensor.
Verify that the repair eliminated the problem.
Result: A -4 code did not become active.
Proceed to Test Step 4.
3. Create an Open at the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor with the active -4 code.
C. Connect Cat ET.
D. Use Cat ET to monitor the following:
- -3 code
E. Turn the keyswitch to the OFF position.
Create an Open
Result: A -3 code became active.
Repair: The wiring harness is OK. Replace the sensor.
Verify that the repair eliminated the problem.
Result: A -3 code did not become active.
Proceed to Test Step 4.
4. Check the 8 VDC Supply Voltage at the Sensor Connector
A. Turn the keyswitch to the ON position.
B. Measure the voltage at the following pin locations of the affected sensor connector:
- Pin 1 and Pin 2
C. Reconnect the sensor.
Supply Voltage
Result: The supply voltage is approximately 8.0 0.2 VDC
Proceed to Test Step 8.
Result: The supply voltage is not approximately 8.0 0.2 VDC.
Repair: There is a short in the wiring harness to the battery. Repair or replace the wiring harness.
If the problem is not resolved, proceed to Test Step 5.
5. Check the PWM Circuit for an Open
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor with the active -8 code.
C. Disconnect the J2 connector at the Electronic Control Module (ECM).
D. Measure the
