Electronic Actuator:

An actuator regulates the turbo pressure within the engine. Without proper pressure control, the turbo would keep forcing air into the engine without adjustment. The actuator guarantees that the turbo pressure is tailored to the specific conditions, ensuring optimal performance for both the turbo and the engine. The Electronic Actuator features electrical circuits that transmit pulses or signals to a motor. This motor, in turn, adjusts the position of the actuator arm connected to the variable vanes. Within the actuator, there are predefined start and stop positions that govern the turbo's boost control. These positions vary slightly for each turbo, rendering each electronic actuator uniquely tailored to a specific unit  

Electronic Boost Pressure Control

Modern diesel and petrol engines are almost universally equipped with exhaust gas turbochargers to enhance performance and efficiency. To maintain optimal boost pressure under varying load conditions, electronic boost pressure control systems are used in most modern vehicles.

Common Actuator Malfunctions:

A malfunctioning turbo actuator typically doesn't result in engine damage but does lead to a decrease in power. This reduced power may be due to partial or complete turbo failure or a lack of power in the vehicle. The actuator comprises multiple components, including an electric motor, plastic worm wheel, and printed circuit boards, all of which can develop weaknesses. In the event of component failure, Turbovanes can provide replacements.

Turbocharger Actuator for Exhaust Gas Turbochargers

The turbocharger actuator, also known as a control box or boost pressure regulator, is an electronic device used in Variable Nozzle Turbine (VNT) and Variable Turbine Geometry (VTG) turbochargers.

It precisely controls the guide vanes, adjusting exhaust flow to the turbine wheel and optimizing boost pressure across all engine speeds. The engine control unit (ECU) sends signals to the actuator, which adjusts the vanes to match the required boost pressure.

Benefits of Electronic Control:

  • Faster turbocharger response at low speeds
  • Precise vane adjustment across speed ranges
  • Improved emission performance

Turbocharger Actuator: Design and Function
The actuator positions the shaft based on ECU specifications or map calculations, using a contactless, inductive position sensor (CIPOS) for precise and wear-free angle measurement. CIPOS technology ensures high accuracy, resistance to magnetic fields, and temperature stability throughout its lifetime. 
Integrated electronics manage the electric motor, detect errors, and enable automatic responses. The actuator operates within a flexible angle range, performing controlled movements up to the limit stop.

Communication with the vehicle is supported via CAN bus or pulse-width modulated (PWM) signals, depending on the model.

Testing and Remanufacturing a Turbo Actuator : 

Turbovanes has designed an in-house test setup that enables the simulation and testing of the actuator. This test evaluates not only the smooth operation of the actuator but also the optimal functioning of its electronics. At the conclusion of the remanufacturing process, a comprehensive final test is performed to guarantee that the remanufactured product performs as effectively as the original one.

Electronic Turbocharger Actuators in comparison to vacuum turbo actuators provide a much faster response time and a much more responsive and precise control of the VNT turbochargers.

Electronic Turbo Actuators are now the chosen control unit of the Turbocharger Wastegate for both passenger and commercial vehicles with diesel engines from as small as 1000cc Turbo engine to over 6500cc size engines.

Turbochargers that have Electronic Turbo Actuators can be identified with an Electronic ‘Black Box’ which would be bolted onto the compressor cover of the turbo's which in turn would be connected to an actuator rod inside the turbocharger.

This type of Electronic Turbo Actuator offers faster response than the vacuum turbo actuator, Turbo control is a lot more precise due to the turbo position sensor; therefore, it helps to improve engine performance and fuel economy.

Electronic Turbo Actuator repairs start from affordable price depending on the damage and will be returned to you normally within 3 days of us receiving the damaged Electronic Turbo Actuator for repairs.


Turbo Actuator brands we can recondition:

▶️ Hella Turbo Actuator

▶️ Garrett Turbo Actuator

▶️ Borg Warner Turbo Actuator

▶️ Mitsubishi Turbo Actuator

Common faults with Electronic Turbo Actuators which can be repaired if the fault is with the Turbocharger Actuator:

◻️ Turbo limp mode 
◻️ Turn the engine off the restart the engine and turbo is working again
◻️ Cutting out when hot
◻️ Whistling noise
◻️ Lights coming on the dash
◻️ Engine management light on
◻️ No boost on the Turbo
◻️ Over boost on the Turbo
◻️ Complete loss of power
◻️ Intermittent low pressure
◻️ ECU error symptoms control
◻️ Fault codes

Typical fault codes shown on diagnostic equipment pointing towards a faulty electronic turbo actuator include:

P132A, P132B, P139A, P1952, P1953, P2263

Several Factors Can NNecessitate a Turbo Actuator Repair:

  • Actuator failures can result from various issues like gearbox, connector, or turbo mishandling, water ingress, power loss, or engine vibrations. 
  • Gearbox problems, often due to "sticky vanes," lead to low boost and limp mode. Board connector issues may only manifest when heated. Turbo mishandling can necessitate full actuator replacement. 
  • Damage from foreign objects may require careful evaluation for repair or replacement. Water ingress can cause rust and contamination. Engine vibrations can wear down electronic actuators.
  • Power loss can cause inefficiencies if the actuator fails to open the nozzle ring, impacting turbo performance.

Electronic Boost Pressure Control Defect: Causes and Troubleshooting

Symptoms of a Faulty Turbocharger Actuator:

  • Loss of performance
  • Poor or sluggish acceleration
  • Engine warning light activation
  • Reduced vehicle speed
  • Vehicle operating in "emergency mode"

Causes of Defect:

  • Stiff or damaged control rod or guide vanes
  • Corrosion of electrical components due to environmental factors (e.g., water, salt)
  • Mechanical damage from external impact
  • Contamination inside the turbocharger causing guide vane malfunction, increased torque demands, and actuator gearbox failure

Repair and Troubleshooting:

  1. Inspection: Begin with a visual check of the turbocharger after diagnosing the ECU.
  2. Diagnosis: Treat the turbocharger and its components as a single unit, as individual parts are often unavailable. Turbocharger and actuator calibration require precision matching, usually done on a specialized flow bench.
  3. Calibration: Some actuators may need pre-activation with specific maps to ensure recognition by the ECU.

Actuator Variants:

  • "Smart" Actuators: Feature an integrated control unit for autonomous guide vane adjustment.
  • "Simple" Actuators: Rely on the ECU for guide vane control.

Both versions differ in electronics, gearbox design, and housing, making component interchangeability impractical.
