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 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
- 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 HARNESS AND CONNECTOR (TURBO MOTOR DRIVER - NOZZLE VANE POSITION SENSOR) |
Disconnect the nozzle vane position sensor (for Bank 1) connector.
Disconnect the nozzle vane position sensor (for Bank 2) connector.
Disconnect the turbo motor driver connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance (Check for Open):
for Bank 1 Tester Connection Condition Specified Condition A48-21 (VTAI) - C89-1 (VTA1) Always Below 1 Ω A48-12 (VNE2) - C89-2 (VNE2) Always Below 1 Ω A48-6 (VNVC) - C89-3 (VNVC) Always Below 1 Ω A48-22 (VTA) - C89-4 (VTA) Always Below 1 Ω A48-13 (E2S) - C89-5 (E2S) Always Below 1 Ω A48-7 (VCS) - C89-6 (VCS) Always Below 1 Ω for Bank 2 Tester Connection Condition Specified Condition A48-23 (VTI2) - z66-1 (VTI2) Always Below 1 Ω A48-14 (VE2) - z66-2 (VE2) Always Below 1 Ω A48-8 (VNC2) - z66-3 (VNC2) Always Below 1 Ω A48-24 (VTA2) - z66-4 (VTA2) Always Below 1 Ω A48-15 (E2S2) - z66-5 (E2S2) Always Below 1 Ω A48-9 (VCS2) - z66-6 (VCS2) Always Below 1 Ω
- Standard Resistance (Check for Short):
for Bank 1 Tester Connection Condition Specified Condition A48-21 (VTAI) or C89-1 (VTA1) - Body ground Always 10 kΩ or higher A48-12 (VNE2) or C89-2 (VNE2) - Body ground Always 10 kΩ or higher A48-6 (VNVC) or C89-3 (VNVC) - Body ground Always 10 kΩ or higher A48-22 (VTA) or C89-4 (VTA) - Body ground Always 10 kΩ or higher A48-13 (E2S) or C89-5 (E2S) - Body ground Always 10 kΩ or higher A48-7 (VCS) or C89-6 (VCS) - Body ground Always 10 kΩ or higher for Bank 2 Tester Connection Condition Specified Condition A48-23 (VTI2) or z66-1 (VTI2) - Body ground Always 10 kΩ or higher A48-14 (VE2) or z66-2 (VE2) - Body ground Always 10 kΩ or higher A48-8 (VNC2) or z66-3 (VNC2) - Body ground Always 10 kΩ or higher A48-24 (VTA2) or z66-4 (VTA2) - Body ground Always 10 kΩ or higher A48-15 (E2S2) or z66-5 (E2S2) - Body ground Always 10 kΩ or higher A48-9 (VCS2) or z66-6 (VCS2) - Body ground Always 10 kΩ or higher
