Diagnostic Trouble Codes for the Active Temperature Sensor Circuit    
J1939 Code    Description    Notes    
3241-3     Exhaust Gas Temperature 1 : Voltage Above Normal     The ECM detects the following conditions:
The signal voltage for the ARD flame detection temperature sensor is greater than 4.7 VDC for at least 4 seconds.
The ECM has been powered for at least 7 seconds.
If equipped, the warning light will come on. The ECM will log the diagnostic code. The engine will be derated.
If a regeneration is in progress, the process will be stopped. Future regenerations will be prevented while the code is active.    
3241-4     Exhaust Gas Temperature 1 : Voltage Below Normal     The ECM detects the following conditions:
The signal voltage for the ARD flame detection temperature sensor is less than 0.3 VDC for at least 4 seconds.
The ECM has been powered for at least 7 seconds.
If equipped, the warning light will come on. The ECM will log the diagnostic code. The engine will be derated.
If a regeneration is in progress, the process will be stopped. Future regenerations will be prevented while the code is active.    
3242-3     Particulate Trap Intake Gas Temperature : Voltage Above Normal     The ECM detects the following conditions:
The signal voltage for the DPF inlet temperature sensor is greater than 4.7 VDC for at least 4 seconds.
The ECM has been powered for at least 7 seconds.
If equipped, the warning light will come on. The ECM will log the diagnostic code. The engine will be derated.
If a regeneration is in progress, the process will be stopped. Future regenerations will be prevented while the code is active.    
3242-4     Particulate Trap Intake Gas Temperature : Voltage Below Normal     The ECM detects the following conditions:
The signal voltage for the DPF inlet temperature sensor is less than 0.3 VDC for at least 4 seconds.
The ECM has been powered for at least 7 seconds.
If equipped, the warning light will come on. The ECM will log the diagnostic code. The engine will be derated.
If a regeneration is in progress, the process will be stopped. Future regenerations will be prevented while the code is active.    Pull-up VoltageThe ECM continuously outputs a pull-up voltage on the circuit for the sensor signal wire. The ECM uses this pull-up voltage in order to detect an open in the signal circuit. When the ECM detects the presence of a voltage that is above a threshold on the signal circuit, the ECM will generate an open circuit diagnostic code XXXX-3 for the sensor.If the sensor is disconnected at the sensor connector, the presence of pull-up voltage at the sensor connector indicates that the wires from the sensor connector to the ECM are not open or shorted to ground. If the sensor is disconnected at the sensor connector, the absence of pull-up voltage at the sensor connector indicates an open in the signal wire or a short to ground. If the sensor is disconnected at the sensor connector and the voltage at the sensor connector is different from pull-up voltage, the signal wire is shorted to another wire in the harness.Note: The DPF inlet/ARD flame detection temperature sensor is a single sensor with two temperature probes. One probe is connected to the DPF. The other probe is connected to the ARD. The probes cannot be disconnected from the sensor.

Turn the keyswitch to the OFF position.
Thoroughly inspect the 31-pin connector, the 40-pin connector, and the connector for the DPF inlet/ARD flame detection temperature sensor. Refer to Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the temperature sensor.
Check the screws for the ECM connector for the correct torque of 6 N m (53 lb in).
Check the harness for abrasions, for pinch points, and for corrosion.Expected Result:All connectors, pins, and sockets are correctly connected. The harness is free of corrosion, of abrasion, and of pinch points.Results:
The connectors and wiring appear to be OK - Proceed to Test Step 2.
There is a fault in the connectors and/or wiring. - Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are correctly installed and ensure that the connectors are correctly connected.If necessary, perform the "Wiggle Test" on the electronic service tool.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Check For Active Diagnostic Codes
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position.
Download the following items before performing any troubleshooting or clearing any diagnostic codes:
Warranty Report
Aftertreatment Regeneration Trigger History
Product Status Report with Histograms
Monitor the active diagnostic code screen on the electronic service tool. Check and record any active diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.Note: A diagnostic code that is logged several times is an indication of an intermittent prob
