Turbocharger Electronic Actuator
The Turbocharger Electronic Actuator controls the turbocharger boost output. It is used in Variable Geometry Turbochargers, which are fitted with movable vanes that determine the direction of the exhaust flow. The actuator acts as a relief valve that can adjust the direction of the vanes and thereby, the direction of the exhaust. It does this with the help of the boost pressure of the primary turbocharger and the vacuum inside the intake manifold. The actuator is controlled by the Engine Control Unit which measures the speed and load on the engine.
At low rpms, the load is low and the actuator keeps the vanes closed. At higher loads, the boost pressure is higher and thus the actuator opens the vanes to allow the exhaust gases to flow over the impeller. This causes the impeller to rotate at a high speed, thereby boosting the pressure in the inlet manifold.
A faulty electronic actuator will cause the vanes to open even at low loads or fail to open the vanes when the load is high. This will cause your vehicle to lose power and the engine light on your dashboard will light up. A defective turbocharger electronic actuator should be replaced at once to prevent any further damage to the turbocharger and the engine.
