DESCRIPTION

The turbocharger system is comprised of the Variable Nozzle (VN) type turbocharger, turbo motor driver and ECM.
The turbocharger has a nozzle vane which opens and closes to control the volume of the exhaust gas flowing into the turbine. This, in turn, controls the boost pressure. When the nozzle vane moves towards the closing direction, the pressure increases. When the vane moves towards the opening direction, the pressure decreases.
The turbocharger actuator, which consists of the DC motor and the nozzle vane position sensor, is built on the turbocharger sub-assembly, and activates the nozzle vane. The nozzle vane position sensor detects the opening angle of the nozzle vane. The turbo motor driver receives an opening angle request from the ECM and a nozzle vane position signal from the nozzle vane position sensor. Based on these signals, the turbo motor driver operates the DC motor and adjusts the nozzle vane opening angle. The turbo motor driver sends the status as a turbo driver status signal to the ECM.
The ECM sends a target nozzle vane position signal to the turbo motor driver to obtain the nozzle vane position for the optimal boost pressure in accordance with the driving conditions.

INSPECTION PROCEDURE

HINT:
  1. 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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
  2. Excessive electrical noise, such as from wireless radios or electrical modifications, may cause a DTC to be stored.
NOTICE:
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
