Code No. P252F: Engine Oil Level Malfunction <Vehicles with closed type DPF>


FUNCTION



  • The engine oil level may ascend if the fuel runs into the engine oil on the DPF regeneration.
  • The engine-ECU monitors the engine driving conditions to estimate the ascend of engine oil level.

TROUBLE JUDGMENT


Check Condition
  • Ignition switch is in "ON" position.
Judgement Criterion
  • The estimated increased amount of the engine oil exceeds the 1,000 cc.

PROBABLE CAUSE



  • The engine oil is increased.

DIAGNOSIS PROCEDURE

STEP 1. Replace the engine oil.

  • Replace the engine oil, When the engine oil is replaced, initialise the learning value (Refer to GROUP 00 - Precautions before Service - Initialisation Procedure for Learning Value in Diesel Particulate Filter (DPF) System ). After initialising the learning value, reconfirm diagnosis code.

Q. Is the diagnosis code set?
Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - Precautions Before Service - How to Perform Chassis Number Writing ). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ). After registering the injector identification code, carry out the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
Check end.
