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.

INSPECTION PROCEDURE
- HINT:
- 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.
| 1.CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2563, P2564, P2565, P2588 AND/OR P2589) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.
Result Result Proceed to P2563, P2564, P2565, P2588 and/or P2589 is output A P2563, P2564, P2565, P2588 and/or P2589 and other DTCs are output B

| 2.CHECK HARNESS AND CONNECTOR (NOZZLE VANE POSITION SENSOR - TURBO MOTOR DRIVER) |
Disconnect the nozzle vane position sensor connector.
Disconnect the turbo motor driver connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition C40-1 (VTA1) - C39-9 (VTA1) Always Below 1 Ω C40-2 (VNE2) - C39-8 (VNE2) Always Below 1 Ω C40-3 (VNVC) - C39-1 (VNVC) Always Below 1 Ω C40-4 (VTA2) - C39-10 (VTA2) Always Below 1 Ω C40-5 (E2S) - C39-11 (E2S) Always Below 1 Ω C40-6 (VCS) - C39-6 (VCS) Always Below 1 Ω C40-1 (VTA1) or C39-9 (VTA1) - Body ground Always 10 kΩ or higher C40-2 (VNE2) or C39-8 (VNE2) - Body ground Always 10 kΩ or higher C40-3 (VNVC) or C39-1 (VNVC) - Body ground Always 10 kΩ or higher C40-4 (VTA2) or C39-10 (VTA2) - Body ground Always 10 kΩ or higher C40-5 (E2S) or C39-11 (E2S) - Body ground Always 10 kΩ or higher C40-6 (VCS) or C39-6 (VCS) - Body ground Always 10 kΩ or higher
