VNTT-PRO Turbocharger actuator tester

VNTT-PRO Turbocharger actuator tester

VNTT-PRO tester is designed to perform diagnosis of actuators (electric valves, DC motors) of VNT(Variable NozzleTurbine) turbochargers.

Apart from testing electronic turbocharger units VNTT- PRO tester can be used to check variable geometry position sensors.

They enable readout of variable geometry vanes opening percentage.
The tester is also able to diagnose boost pressure valve operation.
VNTT-PRO device allows you to check potentiometric sensors and inductive sensors (Hall).

The device supports actuators manufactured by HELLA, SIEMENS, MITSUBISHI, SONCEBOZ, DENSO, MAHLE.

VNTT-PRO device allows you to check:

• - uniformity of actuator lever movement,

• - lever tractive resistance,

• - range of actuator lever movement,

• - mechanical parts as well as actuator electronics,

• - DC motor used in turbo actuators to change lever position,

• - correctness of variable geometry range adjustment,

• - correctness of variable geometry position sensor operation,

• - correctness of internal temperature sensor operation,

• - vacuum solenoid valve controlling turbo actuator.
