The Engine Control Module (ECM) monitors the temperature at the intake of the Diesel Particulate Filter (DPF). The ECM activates the applicable code when the conditions are met.
Note: Refer to Troubleshooting, “Cat ET Service Features” for information about service features.

| E1014 (2) | 3242-18 | Low DPF #1 Intake Temperature | The Aftertreatment Regeneration Device (ARD) has ignited and the ARD has detected Low DPF inlet temperature.
Active regeneration is immediately disabled. Engine power is derated. The code is logged. The code remains active until electrical power to the ECM is cycled. The following conditions can cause this code: The exhaust piping between the outlet of the ARD and the intake of the DPF is disconnected and/or the DPF Inlet Temperature sensor has failed. |

1. Inspect the Exhaust Piping
A. Carefully Inspect the exhaust piping between the outlet of the ARD and the intake of the DPF. Look for the following problems: 1. Missing piping, cracked piping, or disconnected piping |
Damaged or missing piping |
Result: The piping is not damaged or missing.
Proceed to Test Step 2. Result: The piping is damaged or missing. Make the necessary repairs. Proceed to Test Step 2. |
|
2. Inspect the DPF Inlet Temperature Sensor and Wiring
A. Carefully inspect the DPF Inlet temperature sensor wiring for damage. B. Carefully inspect the DPF Inlet temperature sensor for damage. |
Damaged wiring or sensor |
Result: The wiring and sensor are not damaged.
Proceed to Test Step 3. Result: The wiring and sensor are damaged. Make the necessary repairs. Proceed to Test Step 3. |
|
3. Perform an ARD Ignition Test
A. Connect to Cat ET. B. Select the Diagnostics tab. C. Select the Diagnostic Tests tab. D. Select the ARD Ignition Test tab. The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using Cat ET. |
Test was successful |
Result: The ARD Ignition Test was successful.
Return the engine to service. Result: The ARD Ignition Test was not successful. Replace the DPF Inlet Temperature sensor. Repeat the ARD Ignition Test. If the ARD Ignition test was not successful, troubleshoot the generated codes. |
Complete the procedure in the order in which the steps are listed.
