ECD SYSTEM, Diagnostic DTC:P00BB

DTC Code DTC Name
P00BB Fuel Injector Insufficient Flow - Forced Limited Power

DESCRIPTION

In order to detect blockages in the positive pressure filter, the ECM determines if the fuel pressure of the common rail has deviated from the target value every 5000 km. If the average value of the judgment values recorded every 5000 km exceeds the threshold, a blockage is determined to be occurring in the positive pressure filter and a DTC is stored.

Also, at the same time, a message is displayed on the go to service warning light and engine output is limited. The message on the go to service warning light disappears after clearing the DTC.

  • Fuel filter element assembly

  • Fuel filter cap with element

PROCEDURE


  1. CHECK DTC OUTPUT


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG) and turn the GTS on.

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

    4. Read the DTCs.

      Standard
      P00BB is output.

      Tech Tips

      When P00BB is output, the fuel filter cap with element needs to be replaced. In order to inspect the fuel filter element assembly for blockages, do not perform replacement at this stage.

  2. INSPECT FUEL FILTER ELEMENT ASSEMBLY


    1. A01XDZ5

      Disconnect the clogging switch connector from the fuel filter element assembly.

    2. Start the engine and warm it up.

    3. Connect a circuit tester to the clogging switch.

    4. Check that the clogging switch does not turn OFF (10 kΩ or higher) when revving the engine up from idling.

      Tech Tips

      If the clogging switch turns OFF, it can be determined that the fuel filter element assembly is becoming clogged.

      Standard
      The clogging switch does not change from ON (below 1Ω) when revving the engine up from idling.

    OK
