DESCRIPTION
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 turbo motor driver. The turbo motor driver determines the actual nozzle vane position from the electric signals in order to calculate the target nozzle vane position.

WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- After replacing the ECM, the new ECM needs registration (Toyota Fortuner RM0000012XK04BX.html) and initialization (Toyota Fortuner RM000000TIN04NX.html).
- HINT:
- Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is 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.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2563) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.
- Result:

| 2.CHECK HARNESS AND CONNECTOR (NOZZLE VANE POSITION SENSOR - TURBO MOTOR DRIVER) |
Disconnect the T11 nozzle vane position sensor connector.
Disconnect the T34 turbo motor driver connector.
Measure the resistance of the wire harness side connectors.
- Standard resistance (Check for open):
Tester Connection
| Specified Condition
|
VTA1 (T11-1) - VTA1 (T34-9)
| Below 1 Ω
|
VNE2 (T11-2) - VNE2 (T34-8)
| Below 1 Ω
|
VNVC (T11-3) - VNVC (T34-1)
| Below 1 Ω
|
VTA2 (T11-4) - VTA2 (T34-10)
| Below 1 Ω
|
E2S (T11-5) - E2S (T34-11)
| Below 1 Ω
|
VCS (T11-6) - VCS (T34-6)
| Below 1 Ω
|
- Standard resistance (Check for short):
Tester Connection

VNE2 (T11-2) or VNE2 (T34-8) - Body ground
| 10 kΩ or higher
|
VNVC (T11-3) or VNVC (T34-1) - Body ground
| 10 kΩ or higher
|
VTA2 (T11-4) or VTA2 (T34-10) - Body ground
| 10 kΩ or higher
|
E2S (T11-5) or E2S (T34-11) - Body ground

|
| 3.INSPECT TURBO MOTOR DRIVER |
Disconnect the T11 nozzle vane position sensor connector.
Turn the ignition switch ON.
Measure the voltage between the terminals of the nozzle vane position sensor connector.
- Standard voltage:
Tester Connection
| Specified Condition
|
VNVC (T11-3) - VNE2 (T11-2)
| 4.5 to 5.5 V
|
VCS (T11-6) - E2S (T11-5)
| 4.5 to 5.5 V
|
| | REPLACE TURBO MOTOR DRIVER |
|
|
| 4.INSPECT NOZZLE VANE POSITION SENSOR |
Turn the ignition switch ON (IG).
Measure the voltage between the terminals of the turbo motor driver connector.
- Standard voltage:
Tester Connection
| Specified Condition
|
VTA1 (T34-9) - VNE2 (T34-8)
| 0.5 to 4.5 V
|
VTA2 (T34-10) - E2S (T34-11)
