Troubleshooting Test Steps Value Results
1. Diagnostic Codes
A. Establish communitcation with Cat ET. Refer to Troubleshooting, "Electronic Service Tools" for more information.
B. Check for active diagnostic codes.
Codes
Result: Diagnostic codes are present.

B. Use Cat ET to monitor the status of the exhaust temperature while the engine is warming to operating temperature.
C. Ensure that the reading that is displayed is reasonable.
Sensor
Result: The exhaust temperature displays a reasonable reading.
Result: The exhaust temperature reading is NOT reasonable.
Refer to Troubleshooting, "Sensor Signal (PWM) - Test" for information that is related to troubleshooting the circuit that is for the exhaust temperature sensor.
