CLAMP 1P8952 - Caterpillar

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.

Diagnostic Trouble Codes    
CDL Code    J1939 Code    Code Description
(code descriptions may vary)    Comments    
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.

Troubleshooting Test Steps    Values    Results    
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:
Missing piping, cracked piping, or disconnected piping
Broken clamps or missing clamps
   
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.
Repair: 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.
Repair: Replace the DPF Inlet Temperature sensor. Repeat the ARD Ignition Test.
If the ARD Ignition Test was successful, return
