Land Cruiser. Urj200, 202 Grj200 Vdj200.1Vd-Ftv Engine Control.Ecd System (W/ Dpf). Dtc P200C Diesel Particulate Filter Temperature Too High Bank 1

The exhaust fuel addition injector assembly is mounted on the exhaust port of the cylinder head, and low pressure fuel is supplied to the exhaust fuel addition injector assembly by the feed pump in the fuel supply pump assembly. This exhaust fuel addition injector assembly 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 assembly adds fuel to raise the DPF* catalyst temperature.
HINT:
  1. For more information on the exhaust fuel addition injector assembly and DPF, refer to the following procedures (Click here).
  2. If P200C, P200D, P200E, P200F, P2428 and P2429 are present, refer to the diagnostic trouble code (DTC) chart for Diesel Particulate Filter System (Click here).

HINT:
  1. 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 P20CF, P20D5, P244B, P2465, P244C, P244E and P2463 may be stored due to the fact that PM forced regeneration is prohibited due to the fail-safe operation of other DTCs.
  2. The air-fuel ratio and the exhaust gas temperature can be checked by entering the following menus on the GTS: Engine and ECT / Data List / AF Lambda B1S1 (AF Lambda B2S1), Exhaust Temperature B1S1 (Exhaust Temperature B2S1), Exhaust Temperature B1S2 (Exhaust Temperature B2S2) and Exhaust Temperature B1S3 (Exhaust Temperature B2S3).
  3. Malfunctions in the engine itself may affect the DPF system control and cause storage of these DTCs. 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

NOTICE:
  1. After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
  2. After replacing the fuel supply pump assembly, the ECM needs initialization (Click here).
  3. After replacing an injector assembly, the ECM needs registration (Click here).
HINT:
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.
1.READ OUTPUT DTC (RECORD STORED DTC AND FREEZE FRAME DATA) (PROCEDURE 1)

  1. Connect the GTS to the DLC3.

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

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

  1. Record the stored DTC and freeze frame data.

  1. If DTC P200C, P200D, P200E, P200F, P2428 or P2429 is output, the exhaust gas temperature sensors need to be replaced. However, make sure to perform all diagnostic procedures for P200C, P200D, P200E, P200F, P2428 or P2429 before replacing the exhaust gas temperature sensors.

    HINT:
    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.
