*a Exhaust Gas - -

The exhaust fuel addition injector assembly is mounted on the exhaust manifold, and low pressure fuel is supplied to the exhaust fuel addition injector assembly by the feed pump in the fuel supply pump assembly. This injector adds fuel in response to a control signal from the ECM, in order to perform PM forced regeneration.

During PM forced regeneration, the exhaust fuel addition injector adds fuel to raise the DPF* catalyst temperature.

This injector adds fuel by a control signal from the ECM.

This injector is used for two different controls: PM forced regeneration and PM reduction.

During PM forced regeneration, the injector adds fuel to raise the catalyst temperature.

In the other control, the injector helps the air-fuel ratio become rich. As a result, PM in the exhaust gas will be reduced in response to the rich air-fuel ratio.

Tech Tips


  • Due to fail-safe operation when other DTCs (that involve the engine power limit) are stored, PM forced regeneration may be prohibited.

    This DTC or P0420, P20CF, P244B and P2463 may be stored due to the fact that PM forced regeneration is prohibited due to the fail-safe operation of other DTCs.

  • The air-fuel ratio and the exhaust gas temperature can be checked by entering the following menus on the GTS: Powertrain / Engine and ECT / Data List / Diesel Exhaust / AF Lambda B1S1, Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.

  • Malfunctions in the engine itself may affect the DPF system control and cause storage of this DTC. For example, malfunctions in the injector assemblies that cause a large amount of smoke emission: These affect the exhaust fuel addition injector assembly operation. Blockages or leaks in the air intake system, or an EGR system malfunction such as EGR passage blockages: These malfunctions affect the DPF catalyst temperature control. Therefore, the engine condition itself should also be checked, in addition to the exhaust fuel addition injector assembly.

INSPECTION PROCEDURE

Note


  • After replacing the ECM, the new ECM needs registration Click here and initialization Click here.

  • After replacing an injector assembly, the ECM needs registration Click here.

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.

PROCEDURE


  1. READ OUTPUT DTC (RECORD STORED DTC AND FREEZE FRAME DATA) (PROCEDURE 1)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    4. Record the stored DTC and freeze frame data.

  2. REPLACE EXHAUST GAS TEMPERATURE SENSOR


    1. Confirm "Exhaust Temperature B1S1", "Exhaust Temperature B1S2" and "Exhaust Temperature B1S3" in the freeze frame data which was recorded in step 1 and determine which exhaust gas temperature sensor to replace.

      Result
      Result Items to be Replaced
      Exhaust Temperature B1S1 value is 850°C (1562°F) or more Exhaust gas temperature sensor
      Exhaust Temperature B1S2 value is 850°C (1562°F) or more No. 2 exhaust gas temperature sensor
      Exhaust Temperature B1S3 value is 850°C (1562°F) or more No. 3 exhaust gas temperature sensor

    2. If DTC P200C, P200E and/or P2428 is output, the exhaust gas temperature sensors need to be replaced. However, make sure to perform all diagnostic procedures for P200C, P200E and/or P2428 before replacing the exhaust gas temperature sensors.

      Tech Tips

      If the exhaust gas temperature sensors are subjected to an abnormally high temperature, the internal resistance of the sensor increases. This causes incorrect temperature measurement.

  3. CHECK FOR BLACK SMOKE


    1. Start the engine and drive the vehicle until the engine coolant temperature reaches 75°C (167°F) or higher.

    2. Stop the vehicle and allow the engine to idle.

    3. Fully depress the accelerator pedal for 5 seconds, and then release it [A].

    4. Repeat the above procedure [A] 10 times [B].

    5. Check for black smoke emission during procedure [A] and [B].

      OK
      Black smoke is emitted less than 5 times.

      Tech Tips

      Even if the black smoke is very thin, count the number of black smoke emissions if there is any visible smoke.

  4. REPLACE EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY


    1. Even though it has been determined that the exhaust manifold converter sub-assembly (DPF catalyst) needs to be replaced, make sure to perform all diagnostic procedures for DTC P200C, P200E and/or P2428 before replacing it.

      Tech Tips

      This DTC is stored because an excessive amount of PM has accumulated and resulted in abnormal combustion. It is necessary to diagnose the cause of abnormal PM accumulation and repair the problem. Therefore, do not perform replacement at this time.
