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.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
---|---|---|---|---|---|

CAUTION / NOTICE / HINT
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).
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 OTHER DTC OUTPUT (IN ADDITION TO DTC P2564 OR P2565)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read the DTCs.

CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off and leave the vehicle for 15 seconds.
Turn the ignition switch to ON for 1 second.
Turn the GTS on.
Confirm that the DTC is not output.
Perform the following procedure using the GTS to determine whether or not the DTC judgment has been carried out.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Powertrain > Engine and ECT > UtilityTester Display |
---|
All Readiness |
Input DTC P2564 and/or P2565.
Check that STATUS is NORMAL. If STATUS is INCOMPLETE or N/A, idle the engine.
