ECD SYSTEM(w/ DPF), Diagnostic DTC:P252F

DTC Code DTC Name
P252F Engine Oil Level High

DESCRIPTION

In the DPF system, after the main injection and at the end of expansion stroke, the injector assembly sprays a small amount of fuel to control PM regeneration; this is called "post injection".

Because the temperature and pressure of the sprayed fuel are low, it arrives at the catalytic converter unburned. The fuel is then oxidized by the catalytic action and the temperature of the DPF catalyst bed increases to burn accumulated soot.

However, some of the unburned fuel goes down to the oil pan through clearances in the cylinder walls. This fuel is mixed into the engine oil, causing the engine oil volume to increase.

P252F

CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

  4. PERFORM ACTIVE TEST USING GTS (FIRST TIME OF ACTIVATE THE DPF REJUVENATE (PM))


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Start the engine.

    5. Clear the DTCs Click here.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the DPF Rejuvenate (PM) / Data List / MAF, Exhaust Temperature B1S1, Exhaust Temperature B1S2, DPF Differential Pressure and DPNR/DPF Status Reju(PM).

      Tech Tips

      After clearing DTCs, immediately enter the Active Test and then drive the vehicle.

    7. Perform the Active Test and then drive the vehicle at a constant engine speed of 2500 to 3000 rpm or more (If DPF Differential Pressure judgment will be performed in the following step, then to keep the MAF at 30 gm/sec or more, use a higher engine rpm range than normal) (shift position: 3rd gear) at a vehicle speed between 65 to 100 km/h (40 to 62 mph).

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      Tech Tips

      While the Active Test being performed, the accelerator pedal opening angle should be kept as constant as possible.

    8. Confirm that both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 reach 220°C (428°F) or higher and the DPNR/DPF Status Reju(PM) turns from "Ready" to "Operate".

      Tech Tips


      • If the exhaust gas temperature does not reach the specified value, drive the vehicle again with a constant engine speed of 2500 to 3000 rpm or more (shift position: 3rd gear) at a vehicle speed between 65 to 100 km/h (40 to 62 mph).

      • Perform Active Test until one of the following conditions is met:


        1. DPNR/DPF Status Reju(PM) displays "Compl".

        2. DPNR/DPF Status Reju(PM) turns from "Operate" to "Ready" even if the cumulative time of "Operate" exceeds 35 minutes.

        3. DPNR/DPF Status Reju(PM) stays "Ready" even if both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 have reached 220°C (428°F) or higher for more than 10 minutes with an engine speed of 2000 rpm or more. (PM regeneration could not operate.)

    9. Take a snapshot with the GTS when the Exhaust Temperature B1S1 and Exhaust Temperature B1S2 rise and become stable.

    10. Enter the following menus: Powertrain / Engine / Data List / DPNR/DPF Status Reju(PM).

    11. Confirm the DPNR/DPF Status Reju(PM).

      Tech Tips


      • While the performing PM regeneration, the DPNR/DPF Status Reju(PM) displays "Operate".

      • If the PM regeneration is stopped (DPNR/DPF Status Reju(PM) displays "Ready") because the exhaust gas temperature is reduced due to the driving conditions, the PM regeneration is restarted automatically (DPNR/DPF Status Reju(PM) displays "Operate") when the exhaust gas temperature is recuperated by high engine speed driving.

      • If the cumulative time of DPNR/DPF Status Reju(PM) at "Operate" exceeds 35 minutes, the Active Test will be canceled. In this case, the DPNR/DPF Status Reju(PM) turns to "Ready" and the Active Test / Activate the DPF Rejuvenate (PM) will be prohibited for one hour while the engine running. Thus, perform the Active Test again after running the engine for one hour.
