Kubota P3013 – Engine Control Unit (ECU) / Common Rail System module: Parked Regeneration Time Out (Tractor)

A parked active regeneration cycle was inhibited or failed to complete within the allotted time due to the Diesel Particulate Filter (DPF) experiencing abnormally low temperatures.

1. 1

   Place the key switch in the OFF position and attach the diagnosis tool to the CAN1 connector.

2. 2

   Turn the key switch to the ON position.

3. 3

   Access the data monitor function and select 'Exhaust Gas Temperature Sensor 0', 'Exhaust Gas Temperature Sensor 1', and 'Exhaust Gas Temperature Sensor 2' to monitor their readings.

4. 4

   Perform the diagnosis tool active test for 'DPF Manual Regeneration' to observe if the sensors are reading the temperature increases correctly.

5. 5

   Check for related fault codes (such as P0543, P0546, and P242C) which indicate specific exhaust gas temperature sensor failures.

1. 1

   Diagnose components

   Diagnose the exhaust gas temperature sensors (T0, T1, and T2) and the engine thermostat to determine which component is preventing the DPF from reaching regeneration temperatures.

2. 2

   Replace exhaust gas temperature sensor

   If an exhaust gas temperature sensor is faulty (reading out of range or dead), remove and replace the affected sensor.

3. 3

   Replace engine thermostat

   If the engine is failing to reach operating temperature (preventing the DPF from getting hot enough), drain the coolant, remove the thermostat housing, and replace the engine thermostat.

4. 4

   Verify repair

   Clear the fault codes and initiate a manual parked regeneration to verify the repair.
