ECD SYSTEM(w/ DPF), Diagnostic DTC:P2564, P2565

DTC Code DTC Name
P2564 Turbocharger/Supercharger Boost Control Position Sensor "A" Circuit Low
P2565 Turbocharger/Supercharger Boost Control Position Sensor "A" Circuit High

DESCRIPTION

The variable nozzle vane type turbocharger consists primarily of a compressor wheel, turbine wheel, nozzle vane, unison ring, DC motor and nozzle vane position sensor.

The nozzle vane position sensor consists of a Hall IC and a magnetic yoke that rotates in unison with the movement of the linkage that actuates the nozzle vane. The nozzle vane position sensor converts the changes in the magnetic flux that are caused by the rotation of the DC motor (hence, the rotation of the magnetic yoke) into electric signals, and outputs them to the ECM. The ECM determines the actual nozzle vane position from the electric signals in order to calculate the target nozzle vane position.

CAUTION / NOTICE / HINT

Note

When replacing the ECM, the ECM needs Registration and Initialization Click here.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. 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 GTS display.

  • 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. CHECK HARNESS AND CONNECTOR (ECM - NOZZLE VANE POSITION SENSOR)


    1. Disconnect the B36 nozzle vane position sensor connector.

    2. Disconnect the B104 ECM connector (for LHD).

    3. Disconnect the B103 ECM connector (for RHD).

    4. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition
      B36-3 (VTA1) - B104-82 (VTAI) Always Below 1 Ω
      B36-1 (VNVC) - B104-67 (VNVC) Always Below 1 Ω
      B36-2 (VNE2) - B104-114 (VNE2) Always Below 1 Ω
      B36-3 (VTA1) or B104-82 (VTAI) - Body ground Always 10 kΩ or higher
      B36-1 (VNVC) or B104-67 (VNVC) - Body ground Always 10 kΩ or higher
      B36-2 (VNE2) or B104-114 (VNE2) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition
      B36-3 (VTA1) - B103-82 (VTAI) Always Below 1 Ω
      B36-1 (VNVC) - B103-67 (VNVC) Always Below 1 Ω
      B36-2 (VNE2) - B103-114 (VNE2) Always Below 1 Ω
      B36-3 (VTA1) or B103-82 (VTAI) - Body ground Always 10 kΩ or higher
      B36-1 (VNVC) or B103-67 (VNVC) - Body ground Always 10 kΩ or higher
      B36-2 (VNE2) or B103-114 (VNE2) - Body ground Always 10 kΩ or higher
