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
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures 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
CHECK HARNESS AND CONNECTOR (NOZZLE VANE POSITION SENSOR - ECM)
Disconnect the nozzle vane position sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.

CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off.
Turn the ignition switch to ON.
Turn the ignition switch off and wait for 30 seconds or more.
Turn the ignition switch to ON and wait for 10 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Confirm that the DTC is not output again.
