ECD SYSTEM(w/ DPF), Diagnostic DTC:P2463

DTC Code DTC Name
P2463 Diesel Particulate Filter Restriction - Soot Accumulation

DESCRIPTION

A01VDVKE05

The DPF catalyst has the ability to reduce particulate matter (PM). The DPF catalyst is a monolithic type catalyst. Alternating passages in the catalyst have either their inlet or outlet blocked. This forces the exhaust gasses to flow through the walls of the passages (see illustration above). Due to the flow of the exhaust gases through micro-cavities in the passage walls, it is called a "wall-flow" type converter.

During driving with PM accumulation exceeding the threshold, when the exhaust temperature exceeds 250°C (482°F) (Ex.: 3rd gear at 65 to 100 km/h (40 to 62 mph)), PM regeneration will be performed and PM accumulation will be reduced.

During PM regeneration, post injection (injector fuel injection during the exhaust stroke) is performed, and exhaust temperature before the DPF catalytic converter increases to approximately 500 to 700°C (932 to 1292°F).

P2463
DTC Detection Drive Pattern DTC Detection Condition Trouble Area
With a warm engine, drive the vehicle at a constant vehicle speed between 65 to 100 km/h (40 to 62 mph) (shift position: 3rd) for 5 minutes.

Amount of PM (Particulate Matter) is the specified value or more

(1 trip detection logic)

  • Blockage in transmitting pipe sub-assembly for differential pressure sensor

  • Blockage in exhaust pipe air hose

  • Exhaust gas leaks

  • Exhaust manifold converter sub-assembly (CCo catalytic converter)

  • No. 2 exhaust manifold converter sub-assembly (DPF catalytic converter)

  • Injector assembly

Tech Tips

Due to fail-safe operation when other DTCs are stored, PM regeneration may be prohibited.

These DTCs may be stored due to the fact that PM regeneration is prohibited due to the fail-safe operation of other DTCs.

MONITOR DESCRIPTION

In order to detect abnormality in the DPF catalytic converter, the ECM monitors the differential pressure in front of and behind the DPF catalyst.


CAUTION / NOTICE / HINT

Note


  • When replacing the ECM, injector assembly and/or DPF catalyst, the ECM needs Registration and Initialization Click here.

  • When cleaning the electric EGR control valve assembly or diesel throttle body assembly, use a piece of cloth soaked with cleaning solvent. Spraying solvent directly onto these parts or soaking the parts in solvent may damage the parts.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the intelligent tester. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the tester display.

  • Read freeze frame data using the intelligent tester. 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.

  • Before performing the repair, confirm the recent operation conditions with the customer. If the vehicle is driven primarily at low speeds or under light load, the DPF catalytic temperature does not increase, and PM will accumulate.

    Under these conditions, even if the DPF catalytic converter and the engine are operating normally, the DTC might be stored.

    In this case, perform PM regeneration using the intelligent tester, check that the DTC does not recur, and then return the vehicle to the customer.

      Note

      Do not fill engine oil above the full level mark.

      Tech Tips


      • Toyota recommends the use of approved "Toyota genuine motor oil". Another oil of matching quality can also be used.

        Oil grade: ACEA C2

      • Using engine oil other than ACEA C2 may damage the catalytic converter.

      • ACEA C2 is best choice for prevention of increasing the DPF differential pressure.

    3. Reset the oil maintenance indicator Click here.

    4. Start the engine and warm it up until the engine coolant temperature reaches 75 to 86°C (167 to 187°F).

    5. Drive the vehicle for 2 minutes or more at an engine speed of 1800 to 3000 rpm and a vehicle speed of 15 km/h (9.3 mph) or more.

    1. Check the engine assembly to determine the cause of low compression and other factors that would cause the exhaust gas temperature to rise insufficiently.

      Tech Tips

      The speed of each cylinder can be measured (compression test) by using the intelligent tester.

      In the compression test, perform Active Test using intelligent tester (Check the Cylinder Compression) and crank the engine for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.


      1. Warm up the engine.

      2. Turn the ignition switch off.

      3. Connect the intelligent tester to the DLC3.

      4. Turn the ignition switch to ON and turn the tester on.

    2. Start the engine and turn the tester on.

    3. Clear the DTCs Click here.

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

      Tech Tips

      After clearing DTCs, immediately enter the Active Test / Activate the DPF Rejuvenate (PM), and then drive the vehicle.

    5. Perform the Active Test and then drive the vehicle at a constant engine speed of 2000 rpm or more (shift position: 3rd) and a vehicle speed within 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 / Activate the DPF Rejuvenate (PM) is performing, the accelerator pedal opening angle should be kept as constant as possible.

    6. Confirm that both Exhaust Temperature B1S1 and Exhaust Temperature B1S2 reach 250°C (482°F) or more 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 2000 rpm or more (shift position: 3rd) and a vehicle speed within 65 to 100 km/h (40 to 62 mph).

      • Perform Active Test / Activate the DPF Rejuvenate(PM) until the DPNR/DPF Status Reju(PM) displays "Compl".

  22. READ VALUE USING INTELLIGENT TESTER (PM ACCUMULATION RATIO)


    1. Drive the vehicle at a constant engine speed of 2000 rpm or more (shift position: 3rd) and a vehicle speed within 65 to 100 km/h (40 to 62 mph) for 5 minutes or more.

      CAUTION:

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

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to ON and turn the tester on.

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

    5. Enter the following menus: Powertrain / Engine and ECT / Data List / PM Accumulation Ratio.

    6. Take a snapshot with the tester at an engine speed of 4000 rpm without load.

      Tech Tips


      • When reading the values of Data List, confirm that PM regeneration is not activating (value of "After Injection Period" is 0) by entering the following menus: Powertrain / Engine and ECT / Data List / After Injection Period.

        If PM regeneration is activating (value of "After Injection Period" is not 0), drive the vehicle until the PM regeneration is complete (value of "After Injection Period" becomes 0).

      • Detailed graphs can be displayed by transferring the stored snapshot from the tester to a PC (personal computer) with Intelligent Viewer installed.

      Standard
      "PM Accumulation Rate before the first PM regeneration" - "PM Accumulation Rate after the second PM regeneration" is 50% or more.

      Tech Tips

      In some cases, even if the "PM Accumulation Rate before the first PM regeneration" - "PM Accumulation Rate after the second PM regeneration" is less than 50%, the DPF catalytic converter is normal when the value of PM Accumulation Rate after the second PM regeneration is 40% or less.
