What is a turbo actuator?

A turbocharger uses a vehicle’s exhaust to power a turbine, which forces more air into the vehicle’s engine, to help it go faster.

As the important part of TURBO, A turbo actuator is a valve that diverts exhaust gases away from the turbine wheel — helping to control the speed of the turbine and prevent it from over-speeding, and in turn, regulating the speed of the compressor and so the boost pressure.

It controls the speed of the TURBO, preventing it from over-speeding, and regulating the speed of the compressor. Ultimately, this helps to protect the turbocharger from unnecessary wear and tear, by capping the maximum boost pressure of the turbo at a safe level.

How does Turbo actuator work?

A turbo actuator is a fairly simple piece of equipment — it features a spring and a diaphragm. The spring holds the wastegate shut until the boost pressure reaches a set level, and then opens, allowing the gas to escape and reducing the boost pressure.

What problem does Turbo actuator may have?

As with all components, things can go wrong with Turbo actuator.

Over time, the pressure and heat will start to take its toll, which can weaken the spring. This can lead to the wastegate opening earlier than it should, reducing the boost pressure and performance of the turbo.

The diaphragm can also fail, meaning that the valve will no longer open. This can lead to the boost pressure rising to the point that it causes serious, catastrophic damage to your engine!

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.
